If both the integers are negative, then their sum is _____
Answer:
they are always positive
Step-by-step explanation:
they are always positive because two negatives equal a positive.
If both the integers are negative, then their sum is always negative.
We need to find if both the integers are negative, then what is their sum.
What are integers rules?Adding integers is the process of finding the sum of two or more integers. It may result in an increase or a decrease in value, depending on whether the integers are positive or negative or a mixture. The addition of integers is an arithmetic operation performed on integers with the same sign or with different signs to find the sum.
Adding two positive integers always results in a positive value that is greater than both the integers.Adding two negative integers always results in a negative number that is smaller than the given numbers.Therefore, if both the integers are negative, then their sum is always negative.

if 1/4x=5-1/2 y what is the value of 8x-1
Answer:
8x - 1 = 159 - 16y
Step-by-step explanation:
1/4x=5-1/2 y what is the value of 8x-1
Beginning from the given equation, we will find the required
Which mean, we will transform the left hand side (1/4 x) to (8x-1)
[tex]\frac{1}{4} x=5-\frac{1}{2} y[/tex] multiply both sides by 4
∴ x = 20 - 2y
multiply both sides by 8
∴ 8x = 8 * ( 20 - 2y)
∴ 8x = 160 - 16y
Subtract 1 from both sides
8x - 1 = 160 - 16y - 1
∴ 8x - 1 = 159 - 16y
So, the value of 8x - 1 = 159 - 16y

Step 1: Given
BD bisects ∠ADC
Step 2: Given
BD ⊥ AC
Step 3: Corresponding Parts of Congruence Triangles are Congruent
∠1 ≅ ∠2
Step 4: By definition of perpendicular
∠ABD = ∠CBD = 90° (BD ⊥ AC )
∠3 and ∠4 are right angles.

The equations give the total cost for x hours of work for each painter. For how many hours of work are Otis's and Shireen's costs equal? what is the cost for this number of hours?
Y= 45x + 75 - Otis
Y= 55x + 30 - Shireen
Answer:
For 4.5 hours of work Otis's and Shireen's costs are equal
The cost for this number of hours is $277.5
Step-by-step explanation:
Let
x ----> the number of hours
y ----> the total cost
we have
Otis
[tex]y=45x+75[/tex] ----> equation A
Shireen
[tex]y=55x+30[/tex] -----> equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (4.5,277.5)

The probability of drawing a yellow or green marble out of a bag containing 3 blue, 2 green , 8 yellow , 4 red , and 3 orange marbles.
Final answer:
The probability of drawing a yellow or green marble from a bag with various colored marbles is calculated by adding the individual probabilities of drawing a yellow marble and a green marble. Since there are 8 yellow and 2 green marbles out of a total of 20, the combined probability is 0.5 or 50%.
Explanation:
The question relates to the probability of drawing a yellow or green marble from a bag containing marbles of various colors. To find this probability, we must consider the total number of marbles and the number of yellow and green marbles specifically. If a bag contains 3 blue, 2 green, 8 yellow, 4 red, and 3 orange marbles, the total count of marbles is 20.
The probability of drawing a yellow marble (P(Yellow)) is the number of yellow marbles divided by the total number of marbles, which is 8/20 or 0.4. The probability of drawing a green marble (P(Green)) is the number of green marbles divided by the total number of marbles, which is 2/20 or 0.1.
The combined probability of drawing either a yellow or a green marble is found by adding the individual probabilities because these two events are mutually exclusive (they cannot both happen at the same time). So, the probability of drawing a yellow or green marble (P(Yellow or Green)) is P(Yellow) + P(Green) = 0.4 + 0.1 = 0.5.
Therefore, the probability of drawing a yellow or green marble is 0.5 or 50%.

target sells 25 bottles of water for 3 dollars, and 36 bottles for 4 dollars. Which is a better buy and by how much? PLEASE REPLY ILL GIVE BRAINLIEST
Answer:
36 bottles for 4 is a slightly better deal per bottle.
Step-by-step explanation:
3÷25=0.124÷36=0.11111111The cost per bottle is 0.1111111$ per bottle in the 36 pack.
Answer:
36 bottles for $4
Step-by-step explanation:
First you need to calculate the price for one bottle, the lower the cost, the better buy. Do this by dividing the price by the amount of bottles:
= $3 ÷ 24
= 0.125 cents
= $4 ÷ 36
= 0.111 cents
The cheaper option and the better buy is the 36 bottles for $4.
To find the product of 42.12 and 10³, move the decimal point in 42.12 __ places to the right because 10³ has __ zeros.
Solution:
Given that,
[tex]\text{ product of } 42.12 \text{ and } 10^3[/tex]
Which means,
[tex]42.12 \times 10^3[/tex]
Here, the exponent of 10 is positive ( which is 3)
When the exponent is positive, we have to move the decimal point to right
When you multiply a number by a power of 10, ( 10!, 10^2, and so on ) move the decimal point of the number to the right the same number of places as the number of zeros in the power of 10
Here, exponent is 3 , therefore move the decimal point right 3 places in 42.12
Therefore,
[tex]42.12 \times 10^3 = 42120[/tex]

Answer:
the answer is 5 1/4
Step-by-step explanation:
because u flip it then multiply then u get ur answer
To divide 1/6 and 7/8, we first find the reciprocal of 7/8 which is 8/7, then multiply 1/6 by 8/7 to get 8/42. We simplify this fraction to lowest terms by dividing both the numerator and denominator by their GCD, which is 2, to get the final result, 4/21.
Explanation:This mathematics question is asking you to divide two fractions, which is 1/6 and 7/8. To do this, you would multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is achieved by switching the numerator and the denominator.
In this case, the reciprocal of 7/8 is 8/7. So, the equation becomes 1/6 * 8/7, which simplifies to 8/42. But this is not in lowest terms. To find the fraction in lowest terms, you would find the Greatest Common Divisor (GCD) of the numerator and the denominator. In this case, the GCD of 8 and 42 is 2.
Dividing both the numerator and denominator by 2, we get 4/21, which is the fraction in lowest terms.
