Answer:
10 nickels and 10 quarters
Step-by-step explanation:
Given
Number of coins: 20
Vaiue of coins = $3.00
Required
Number of Nickels and Quarters;
<em>Let N =Nickels and Q =Quarters</em>
The total coins is represented as:
1 nickel is equivalent to $0.05 and 1 quarter is equivalent to $0.25; So
Make N the subject of formula in the first equation
Substitute this in the second equation

Recall that N = 20 - Q
Answer:
if 
is divided by 
, the remainder is -9
Step-by-step explanation:
We need to find the remainder if is divided by
Dividing by
The division is shown in figure attached.
The remainder = -9
The quotient = x+3
So, if is divided by , the remainder is -9
EF = 50 in.
In similar figures, corresponding sides are proportional. We use the similarity statement ABCD~EFGH to write a proportion:
Cross multiply the proportion:
45*x = 75*30
45x = 2250
Divide both sides by 45:
45x/45 = 2250/45
x = 50
Answer:
it's b 59° because it's at the side
