Answer:
Total number of quarters=10
Total number of nickels=19
Step-by-step explanation:
The expression for the total value of money you have is;
Quarters have a value of= $0.25
Nickels have a value of= $0.05
Total value=(value of quarters×number of quarters)+(value of nickels×number of nickels)
where;
Total value=$3.45
Value of a quarter=$0.25
number of quarters=x
Value of a nickel=0.05
number of nickels=y, but y=x+9
replacing;
3.45=(0.25×x)+0.05(x+9)
3.45=0.25 x+0.05 x+0.45
3.45=0.3 x+0.45
0.3 x=3.45-0.45
0.3 x=3
x=3/0.3
x=10
y=x+9=10+9=19
Total number of quarters=10
Total number of nickels=19

65/5
Answer:
Suppose you have two similar figures , one larger than the other. The scale factor is the ratio of the length of a side of one figure to the length of the corresponding side of the other figure. Here, XYUV=123=4 . So, the scale factor is 4 .Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor .
