Answer: x= -4
Step-by-step explanation:
Combine like terms
-4x -7 -3x + 4 = 25
-7x -3 =25
Add 3 on both sides
-7x=28
Divide by -7 on both sides
x= -4
Hope this helps! :)
a. Write and graph an equation in two variables that represents the total cost of ordering the shirts.
For this case, the first thing we must do is define variables:
c = total cost
x = x number of shirts.
The equation that adapts to the problem is:
c (x) = 10x + 20
Answer:
c (x) = 10x + 20
b. Choose an ordered pair that lies on your graph in part (a). Interpret it in the context of the problem.
Let's choose the next ordered pair:
(x, c (x)) = (0, 20)
We verify that it is in the graph:
c (20) = 10 (0) + 20
c (20) = 20 (yes, it belongs to the graph).
In the context of the problem, this point means that the cost per shipment is $ 20
Answer:
(0, 20)
Cost per shipment is $ 20
Answer:
21 1/2 yd
Step-by-step explanation:
43/4 + 43/4 = 21 1/2 yd
4 + (14 - 2) = 4 + 14 - 2
A. 4 - (-14 - 2) = 4 + 14 + 2 ------------------------WRONG
B. (4 - 14 ) - 2 = 4 - 14 - 2 --------------------------WRONG
C. 4 - (-14) - (2) = 4 + 14 - 2 ------------------------RIGHT
D. 4 + 14 + (-2) = 4 + 14 - 2 ------------------------RIGHT
E. - (-4 - 14) - 2 = 4 + 14 - 2 ------------------------RIGHT
Answer: C, D and E.
Answer:
Step-by-step explanation:
35.7826087
I'm guessing you want it estimated to the nearest tenth so 35.8
