Answer:
RQ = 10
Step-by-step explanation:
When two triangles are similar, the ratio of their corresponding sides are equal;
Thus, we have it that;
QP/RQ = BC/AB
12/RQ = 36/30
RQ = 12 * 30/36 = 10
Answer:
Number 1 is 12.
Step-by-step explanation:
{Solve by cross multiplication}
17 • x = 3 • (80 - x)
{Multiply 3 by distribution,}
17x = 240 - 3x
{Add 3x to both sides of the equation,}
20x = 240
{Divide through out by 20,}
20r/20 = 240/20
x = 12
Thus there were 12 pens :)

Answer:
$58.33
Step-by-step explanation:
From the question;
If you spent $7.00 of the savings which is 12% of the savings, then we can determine the savings you had.
We need to know that the total savings is 100%
Therefore;
If $7.00 = 12%
Then;
The total savings will be given by;
= ($7.00 × 100%) ÷ 12%
= $58.33
Therefore, the amount of savings you had is $58.33
