Answer:3 1/2x = 280
Step-by-step explanation: Subtract 215 from both sides.
Answer:
subtract 215 from both sides
x = 80
Step-by-step explanation:
to get the 3 1/2 x alone subtract 215 from both sides.
this moves it to the other side.
495-215 =280
3 1/2 x = 280
divide both sides by 3 1/2
this will solve for x
x = 80

Trina's car uses 12 gallons of gas to travel 144 miles. If she has 6 gallons of gas in the tank, how much more gas will she need to drive 240 miles?
Answer:
34
Step-by-step explanation:
ok so first you need to divide 144 by 12 = 12
then you need to figure if you split that in half it equals 6.
now we know that for every 12 miles you drive, you need 1 gallon of gas
now you need to divide 240 by 6 = 40
so you will need 40 gallons of gas to drive that far
we are not one yet, then you need to take away 6 from 40 witch comes to 34.
so you will need 34 more gallons of gas

The 1 copy makes the cost equivalent in two options and the cost of 1 copy is $41.
Step-by-step explanation:
The given information are that,
Elsa could use a printer in which it cost a $38 setup fee and $3 for each copy.
Elsa could go to a supply store in which it cost $36 up-front fee and $5 for each copy.
To find the same amount for certain number of copies in both the cases :
Let us assume that the number of copies be 'x'.
In the first case, the total cost will be = setup fee + cost for x copies.
⇒ Total cost = 38 + 3x
In the second case, the total cost will be = up-front fee + cost for x copies.
⇒ Total cost = 36 + 5x
To find the x value :
Equating the total cost of both the cases, we get
⇒ 38 + 3x = 36 + 5x
⇒ 38-36 = 5x-3x
⇒ 2 = 2x
⇒ x = 1 copy
Therefore, taking 1 copy make the two options equivalent in terms of cost.
The cost of 1 copy = 38+ 3(1) = 41 dollars.
Therefore, it would cost $41 for 1 copy.
What is the answer to 1.5=0.6(w+0.4)
Answer:
W= 2.1
Step-by-step explanation:
The solution to the equation 1.5 = 0.6( w + 0.4 ) is w = 2.1.
What is the solution to the given equation?Given the equation in the question:
1.5 = 0.6( w + 0.4 )
To solve the equation 1.5 = 0.6(w + 0.4) for "w," first apply distributive property:
1.5 = 0.6( w + 0.4 )
Distribute 0.6 on the right side of the equation:
1.5 = 0.6(w) + 0.6(0.4)
Simplifying, we get:
1.5 = 0.6w + 0.24
Subtract 0.24 from both sides of the equation:
1.5 - 0.24 = 0.6w + 0.24 - 0.24
1.5 - 0.24 = 0.6w
1.26 = 0.6w
0.6w = 1.26
To solve for "w", divide both sides by 0.6:
0.6w / 0.6 = 1.26 / 0.6
w = 1.26 / 0.6
w = 2.1
Therefore, the value of w is 2.1.

Mr. Thompson got some money for his birthday He spent 1/5 of it on dog treats. Then, he divided the remainder among his 3 favorite charities.
If he donated $60 to each charity, how much money did he receive for his birthday?
Answer:
$225 of birthday money
Step-by-step explanation:
he spent 20 percent (1/5) of the money on dog treats, and the remaining 80 percent (4/5) went to 3 different charities. If $60 dollars were given to each charity, that means a total of $180 dollars was given to charity. if 4/5 of the money is equal to $180, we can divide 180 by 4 to get $45 dollars. this means that 1/5 of the birthday money would be equal to $45 dollars. so to find 5/5, or 100% of the money, simply multiply $45 by the denominator, 5, to get the answer. the total birthday money received was $225 dollars, and $45 dollars of that was used for dog treats.
The amount of money Mr. Thompson received for his birthday, work backwards from how much he donated to charities after spending 1/5 on dog treats, resulting in $300.
To find out how much money Mr. Thompson received for his birthday, we will work backwards from the information given.
Let's assume he received x amount of money for his birthday.
He spent 1/5 of it on dog treats, so he spent (1/5)x on dog treats.
The remainder after buying the dog treats is (4/5)x.
Since he divided this among 3 charities, each charity received $60, so [tex](\frac{4}{5} )x = 3*60.[/tex]
Solving this equation, we find x = $300.
Hence, Mr. Thompson received $300 for his birthday.
In the figure below, \overline{AD} AD start overline, A, D, end overline and \overline{BE} BE start overline, B, E, end overline are diameters of circle PPP. What is the arc measure of \stackrel{\LARGE{\frown}}{CD} CD ⌢ C, D, start superscript, \frown, end superscript in degrees? ^\circ ∘ degrees
Answer:
The measure of the arc CD = 64°
Step-by-step explanation:
It is required to find the measure of the arc CD in degrees.
So, as shown at the graph
BE and AD are are diameters of circle P
And ∠APE is a right angle ⇒ ∠APE = 90°
So, BE⊥AD
And so, ∠BPE = 90° ⇒(1)
But it is given: ∠BPE = (33k-9)° ⇒(2)
From (1) and (2)
∴ 33k - 9 = 90
∴ 33k = 90 + 9 = 99
∴ k = 99/33 = 3
The measure of the arc CD = ∠CPD = 20k + 4
By substitution with k
∴ The measure of the arc CD = 20*3 + 4 = 60 + 4 = 64°

Find the equation of a line that passes through the point
(0,7) with a slope that is the opposite of the slope of the
line with equation y = -x -5.
Answer:
y=x+7
Step-by-step explanation:
y-7=1(x-0)
y-7=x-0
y=x+7
Answer:
y=x+7
Step-by-step explanation:
You need a slope that is opposite the slope of equation y=-x-5. To do this you need to find the opposite reciprocal. For -1, the opposite reciprocal would be 1. So, your slope is going to be 1.
You need the line to pass through (0,7), which is a point on the y axis. b in y=mx+b is the y-intercept. So, you would make 7 your b.
By plugging in these numbers you end up with y = x + 7

solve the equation 4x — 3y = y —12 for x if y is 6. Make sure to first solve the equation for x in terms of y. X= ________
Answer:
x = 3
Step-by-step explanation:
4x - 3y = y - 12
If y = 6
4x - 3 x 6 = 6 - 12
4x -18 = -6
Add 18 to both sides
4x - 18 + 18 = -6 + 18
4x = 12
Divide both sides by 4
x = 12/4
x = 3

Write 6-1 as a fraction.
Answer: 5/1
Step-by-step explanation:
6-1=5
put that under 1 to make the fraction 5/1
I'm unsure if this is correct, but I assume the answer shall be:
6-1/1, Both numbers are whole numbers. So, as a fraction, whole numbers are put over 1. So 6 minus 1 over 1. (Sorry if this is incorrect.)
The width of a rectangle is 4x - 4.25 feet and the length is 7x + 7 feet. Write and
expression to find the perimeter of the rectangle.
Perimeter is 2l+2w in the case of a rectangle, so you would write:
2(4x - 4.25) + 2(7x +7)
Answer: The expression can be written as Perimeter = 22x + 5.5
Step-by-step explanation: The perimeter of a rectangle is given as 2(L + W), where L is the length and W is the width. In the question, the length L has been given as 7x + 7 while the width W has been given as 4x - 4.25.
Inserting the values of the length and the width, the perimeter can now be properly written as,
Perimeter = 2(L + W)
Perimeter = 2( {7x + 7} + {4x - 4.25} )
By collecting like terms we now have
Perimeter = 2(11x + 2.75)
Perimeter = 22x + 5.5
