Answer:
(x, y) = (-8, 19)
Step-by-step explanation:
9x + 3y = -15
-4x - 3y = -25
(9x + 3y) + ((-4x) - 3y) = -15 + (-25)
5x = -40
x = -8.
So,
9x + 3y = -15
9 * (-8) + 3y = -15
-72 + 3y = -15
3y = 57
y = 19

A train traveled 1/4 of the distance between two cities in 2/3 of an hour. at this rate, what fraction of the distance can the train travel in one hour
Answers
====================================================
Explanation:
A = fraction of the distance traveled in 2/3 of an hourB = time value that pairs up with AC = fraction of the distance traveled in 1 hourD = time value that pairs with CIn this case,
A = 1/4B = 2/3C = unknownD = 1We can set up the proportion
A/B = C/D
Which cross multiplies to
A*D = B*C
Let's plug in the known values and solve for C
A*D = B*C
(1/4)*(1) = (2/3)*C
1/4 = (2/3)*C
(2/3)*C = 1/4
3*(2/3)*C = 3*(1/4) ..... multiply both sides by 3
2C = 3/4
(1/2)*2C = (1/2)*(3/4) .... multiply both sides by 1/2
C = (1*3)/(2*4)
C = 3/8
The train travels 3/8 of the distance in 1 hour.

if 10 shirts cost $80, what is the unit rate (the cost of 1 shirt)?
Answers
Answer:
Each shirt is $8
Step-by-step explanation:
80÷10 = 8
Answer:
$8
Step-by-step explanation:
Form your equation, there are 10 shirts at x price, and they equal $80:
10x = $80
solve for x by dividing both sides by 10
10x/10 = $80/10
x = $8
what is x? -2.5x- 2=18
Answers
Answer:

Add 2 to both sides.
-2.5x = 20.
Divide both sides by -2.5.
x = -8
2. If 1/2 of a gallon of paint covers 1/8 of a wall, how much paint is needed to cover the entire wall?
A) 8 2/3 gallons
B) 8 1/3 gallons
C) 3 gallons
D) 2 gallons
Please help !
Answers
C.) 3 gallons
Answer: 4 gallons.
Step-by-step explanation:
With this equation, we can use the ratio 1/2 : 1/8. For every 1/2 gallon of paint, 1/8 of a wall is painted.
If 1/2 gallons covers 1/8 of a wall, then we need 8 of the 1/2 gallons to cover the whole wall. We canrepresent this by multiplying 8 and 1/2.
8 x 1/2 = 4.
Because of this, 4 gallons of paint are needed to cover he entire wall.
(Quick note: I don't know why, but the answer choices seem kind of weird. But the answer is 4 :])

Increase £120 by 35%
Answers
Answer:
£162
Step-by-step explanation:
Let's first find 35% of £120.
35% here is our multiplier, so we can turn it into a decimal (0.35) in order to use it in our sum.
£120 × 35% = £42
Now add £42 to £120.
£120 + £42 = £162
Super simple!
explanation:
50% of 120= 60
5% = 6
30% = 36
35%= 36+6= 42
120+42=162
