5(5r-7)=-185
25r - 35 = - 185
25r = - 150
r = - 6
Answer:
The answer to your question is 11.4 units
Step-by-step explanation:
Data
A (-3, -1)
B ( 0, 3)
C ( 1, 2)
Perimeter = ?
Formula
d = 
Process
1.- Find the length between the points
dAB = 
dAB = 
dAB = 
dAB = 
dAB = 5
dBC= 
dBC = 
dBC = 
dBC = 
dAC = 
dAC = 
dAC = 
dAC =
dAC = 5
2.- Perimeter
P = AB + BC + AC
P = 5 + + 5
P = 10 +
P = 10 + 1.42
P = 11.4
<h3>Answer</h3>
Sale Price = $36.4
Step-by-step explanation:
Sale Price = $36.4 (answer). This means the cost of the item to you is $36.4. You will pay $36.4 for a item with original price of $45.50 when discounted 20%. In this example, if you buy an item at $45.50 with 20% discount, you will pay 45.50 - 9.1 = 36.4 dollars.
Answer:
Step-by-step explanation:
“y varies directly as x”
y = kx
Plug in (4, 1.25) and solve for k:
1.25 = 4k
k = 1.25/4 = 0.3125
The equation becomes
y = 0.3125x
Answer:
The correct answer is D. 8
Step-by-step explanation:
In order to find this, solve by multiplying the top equation by -6. Then add the equations together to get the x values to cancel. Then you may solve for y.
-2x - 3/2y = -6
2x - 3y = -30
--------------------
9/2y = -36
y = 8
