Answer:
5y
Step-by-step explanation:
All you have to do is subtract 1 from both side so subtract 1 from one side than the other. If you have to find out what y equals, then after subtracting, divide 5 from both sides and y would equal 5. Hope this helped
Answer:
1) If you want to solve the equation, x is 0/5 or 0
2) If you want to subtract 1, the answer is 5y = 0
Step-by-step explanation:
1) 5y + 1 = 1
5y = 0
2) 5y + 1 = 1 Subtract both sides by 1
5y = 0 Isolate the variable by dividing 5 on both sides
y = 0/5 or 0
What is 5/3 as a whole number
Answer:
1 and 2/3
Step-by-step explanation:
The fraction 5/3 can be expressed as the mixed number 1 2/3.
The fraction 5/3 cannot be expressed as a whole number because it is an improper fraction. An improper fraction has a numerator that is greater than or equal to the denominator.
To convert the improper fraction 5/3 into a mixed number (a whole number plus a proper fraction), we divide the numerator (5) by the denominator (3):
5 ÷ 3 = 1 remainder 2
The result tells us that 5 divided by 3 equals 1, with a remainder of 2.
Therefore, the fraction 5/3 can be expressed as the mixed number 1 2/3.

Which net represents this solid figure?
Rectangular prism 6.
Net of a cube 5.
Net of a cube 6.
Net of a rectangular prism. Two rectangles have a width of eight units and a height of four units. Two rectangles have a width of eight units and a height of three units. Two rectangles on the left and right have a width of four units and a height of three units.
Net of a rectangular prism 12.
The net represents a rectangular prism with two rectangles of 4x8 units, two rectangles of 8x3 units, and two rectangles of 4x3 units. The net of a cube doesn't match these dimensions, as it has equal sides. The 6 and 12 rectangular prisms do not match, unless they can confirm to these specific dimensions.
Explanation:The question is asking to identify which net corresponds to a specified rectangular prism with given dimensions. A net in mathematics refers to a pattern that you can cut and fold to make a model of a solid shape. A net of a rectangular prism consists of six rectangles of two pairs with equal dimensions - however, within each pair, the two rectangles may not be identical in dimensions to the other pair.
For this case, the rectangular prism described will have two rectangles with a height of 4 units and a width of 8 units, two rectangles with a width of 8 units and a height of 3 units, and two rectangles with a width of 4 units and a height of 3 units.
Thus, the correct net for this rectangular prism is the one with these described dimensions. We can eliminate the net of a cube options as those will have equal sides on all faces, which this prism does not have. The rectangular prism 12, 6, unless they match the above dimensions, also will not be the correct answer.

which pair of points forms line that does no intersect the line that passes through the points (5,7) and (7,7)?
Answer:
(8, -9), (11, -9)
Step-by-step explanation:
The points (5, 7) and (7, 7) are on a horizontal line in which the y-coordinates of all points are 7. The line has equation y = 7.
For a line to not intersect the line y = 7, it must be parallel to y = 7.
The answer is the pair of points which both have the same y-coordinate, and that y-coordinate is not 7.
From the choices you added to your comments, the only choice with two points with the same y-coordinate is (8, -9) and (11, -9). This is the answer.
Answer: (8, -9), (11, -9)

Ona piece of paper usa protracter to construct right trangle ABC with AB = 4in. , m∠A90°, and m∠B= 45°
What statement is true about the triangle?
AC = 2 in.
BC = 8 in.
AC = 4 in.
BC = 4 in.
Answer:
AC = 4 in.
Step-by-step explanation:
Since m∠A = 90° and m∠B = 45°, you know that m∠C = 45° ( because you can tell it's an isosceles right triangle ).
This means that legs AB and AC both have to be congruent.
If leg AB is 4 in, then leg AC is 4 in.

What is the P(H,H,H,T,T) on 5 flips of a coin?
I need help
Answer:
The probability for Heads will be 60% or 3/5.
The probability for Tails will be 40% or 2/5.
Step-by-step explanation:
The coin flipped 5 times and landed on Heads 3 times. This shows that out of 5 situations, 3 situations were Heads. Therefore, the probability is 3/5.
The coin landed on Tails 2/5 times the coin was flipped, which is basically the probability.
The probability of getting 3 heads and 2 tails in 5 flips of a coin, in any order, is 0.3125 or 31.25%. This is calculated by figuring out the number of ways to get 3 heads and 2 tails out of 5 flips (10 ways) and dividing that by the total possible outcomes in 5 flips (32 outcomes).
Explanation:The question is asking about the probability of getting three heads and two tails in 5 flips of a fair coin. The order given in the question (H, H, H, T, T) doesn't matter in this case because the flips are independent events.
We calculate the probability by figuring out the number of ways we could get 3 heads and 2 tails out of 5 flips and divide that by the total number of outcomes in 5 flips of a coin. There are 10 ways to get 3 heads and 2 tails out of 5 flips, and there are 32 total possible outcomes in 5 flips of a coin (because 2^5 = 32, as each flip has 2 possibilities, heads or tails).
So, P(H, H, H, T, T) = 10 / 32 = 0.3125 or 31.25%

What is x?
factor completely (x^2-4)(x^2+6x+9)
Answer:
[tex](x-2)(x+2)\left(x+3\right)^2[/tex] is the required factor form.
Step-by-step explanation:
When the factor of the expression is required to be found, then take the common terms, or find the factor by splitting the terms, or by using the standard formulas.
So here we have to find the factor of the expression:
[tex](x^2-4)(x^2+6x+9)\\[/tex]
so we will first find the factors of:
[tex](x^2-4)=(x-2)(x+2)~~~~~~~~~~~~~~~~~\because x^2-y^2=\left(x+y\right)\left(x-y\right)\\[/tex]
Now the factors of:
[tex](x^2+6x+9)=\left(x+3\right)^2~~~~~~~~~\because \left(a+b\right)^2=a^2+2ab+b^2[/tex]
So the final factor is given as:
[tex](x^2-4)(x^2+6x+9)\\=(x-2)(x+2)\left(x+3\right)^2[/tex]

How do you determine the base when solving for x by converting to a log?
The answer was supposed to be
x= ln(3/2) / 4ln(1.0125)
why is it ln?
[tex]$x=\frac{\ln \left(\frac{3}{2}\right)}{4 \ln (1.0125)}[/tex]
Solution:
Given expression:
[tex]$(1.0125)^{4 x}=\frac{3}{2}[/tex]
To solve the expression:
[tex]$(1.0125)^{4 x}=\frac{3}{2}[/tex]
If f(x) = g(x) then ln(f(x)) = ln(g(x)).
Using the above condition, we can write
[tex]$\ln \left(1.0125^{4 x}\right)=\ln \left(\frac{3}{2}\right)[/tex]
Apply log rule: [tex]\log _{a}\left(x^{b}\right)=b \cdot \log _{a}(x)[/tex]
[tex]$4 x \ln (1.0125)=\ln \left(\frac{3}{2}\right)[/tex]
Divide both side of the equation by [tex]4 \ln (1.0125)[/tex].
[tex]$\frac{4 x \ln (1.0125)}{4 \ln (1.0125)}=\frac{\ln \left(\frac{3}{2}\right)}{4 \ln (1.0125)}[/tex]
[tex]$x=\frac{\ln \left(\frac{3}{2}\right)}{4 \ln (1.0125)}[/tex]
The answer is [tex]x=\frac{\ln \left(\frac{3}{2}\right)}{4 \ln (1.0125)}[/tex].
Final answer:
To solve for x by converting to a logarithm, the base used depends on the context and specific problem. In this case, the natural logarithm is used as the base is relevant to the equation.
Explanation:
To solve for x by converting to a logarithm, you need to determine the base of the logarithm. In this case, the answer is x = ln(3/2) / 4ln(1.0125), where ln represents the natural logarithm.
The natural logarithm, denoted by ln, is the logarithm with base e, where e is an irrational number approximately equal to 2.71828. It is commonly used in calculus and other fields of mathematics.
When converting to a logarithm, the base can be any positive number greater than 1. The choice of base depends on the context and the specific problem being solved. In this case, the natural logarithm is used because it is relevant to the given equation.

Three friends fill bags with trash at a neighborhood cleanup. Randall's bag weighs
3x - 7 pounds, Seth's bag weighs 2x -- 10 pounds, and Joanna's bag weighs
2x + 2 pounds. Together, Randall's and Joanna's bags weigh 3 times as much as
Seth's bag. How many pounds of trash does each friend pick up?
Answer:
Randall picks up 68 pounds
Seth picks up 40 pounds
Joanna picks up 52 pounds
Step-by-step explanation:
Let us make an equation in x to find it
∵ Randall's bag weighs 3x - 7 pounds
∵ Joanna's bag weighs 2x + 2 pounds
∵ Seth's bag weighs 2x - 10 pounds
∵ Randall's and Joanna's bags weigh 3 times as much as Seth's bag
- That means add Randall's bag and Joanna's bag and equate
the sum by 3 times Seth's bag
∵ Randall's bag + Joanna's bag = 3(Seth's bag)
∴ (3x - 7) + (2x + 2) = 3(2x - 10)
- Simplify the two sides
∴ (3x + 2x) + (-7 + 2) = 3(2x) - 3(10)
∴ 5x + (-5) = 6x - 30
∴ 5x - 5 = 6x - 30
- Add 5 to both sides
∴ 5x = 6x - 25
- Subtract 6x from both sides
∴ -x = -25
- Divide both sides by -1
∴ x = 25
Substitute x by 25 in the weight of each bag
∵ Randall's bag weighs = 3(25) - 7 = 75 - 7
∴ Randall's bag weighs = 68 pounds
∵ Seth's bag weighs = 2(25) - 10 = 50 - 10
∴ Seth's bag weighs = 40 pounds
∵ Joanna's bag weighs = 2(25) + 2 = 50 + 2
∴ Joanna's bag weighs = 52 pounds

factor q^2+q+5pq+5p by grouping
Answer:
(q + 1)(q + 5p)
Step-by-step explanation:
q² + q + 5pq + 5p
= (q² + q) + (5pq + 5p)
Consider that : q² + q = q(q + 1) and 5pq + 5p = 5p(q + 1)
then
q² + q + 5pq + 5p
= (q² + q) + (5pq + 5p)
= q(q + 1) + 5p(q + 1)
= (q + 1)(q + 5p)
Good luck :)
Final answer:
The expression q^2 + q + 5pq + 5p is factored by grouping into (q + 5p)(q + 1) by factoring out common factors from the grouped terms.
Explanation:
To factor by grouping the expression q2 + q + 5pq + 5p, we need to group the terms in a way that common factors can be factored out.
Firstly, we divide the expression into two groups:
q2 + q5pq + 5pWe can then factor out the common factor from each group:
q2 + q = q(q + 1)5pq + 5p = 5p(q + 1)Now, we can see that the term (q + 1) is common in both grouped expressions:
q(q + 1) + 5p(q + 1)
The expression can be factored as:
(q + 5p)(q + 1)
This is the factored form of the original expression.
