Answer:
12
Step-by-step explanation:
We can write the following ratio
1:3 (for every student who gets an A 3 gets a b)
We then can write a new ratio
4:x
We can solve this ratio by multiplying the original ratio by 4
4:12
This means that 12 people earned an B
Answer:
<em>Question 7. Option B,</em>
<em>Question 8. Option C</em>
Step-by-step explanation:
<em>Question 7.</em>
Let us create a proportionality, and solve for the value of s, through cross multiplication;

<em>Question 8.</em>
We can solve this problem in a similar manner, through setting a proportionality and solving for the length of the shadow of the tree, which we can pose as x;

Answer: y - 2 = 2(x + 7)
Step-by-step explanation:
Point-slope form is written as y -
= m(x -
) where m is the slope and (
,
) are points on the line.
y -
= m(x -
)
y - 2 = 2(x + 7)
$1,041,666.70 I'm not sure but that what I think the answer is
-x^2+6x+3
hope this helps :)
