Answer: The equation that represents the give situation is, y = 0.75 x + 12
Step-by-step explanation:
Here, x represents the number of batteries the child bought and y represents the total cost.
Since, the cost of one batteries = $ 0.75
⇒ The cost of x batteries = 0.75 x
The cost of one toy = $ 12
Hence, the total cost = The cost of one toy + The cost of x batteries
= y = 0.75 x + 12
Which is the required equation that represents the given situation.
Answer:

Step-by-step explanation:
Since the triangles are congruent then corresponding angles are congruent.
Thus ∠D = ∠A and substituting values
2x = x + 31 ( subtract x from both sides )
x = 31
Hence
∠A = x + 31 = 31 + 31 = 62
∠D = 2x = 2 × 31 = 62
Answer:
y=8x+7
Step-by-step explanation:
Use the form y=mx+b
M= the slope
B= the y-intercept
y=8x+?
Since the y coordinate of (0,7) is 7
b=7
So y=8x+7
Answer:
-10/7
Step-by-step explanation:
w - 5 = 8w + 5
w - 8w = 5 + 5
-7w = 10
w = - 10/7
