Answer:
Let x = the number of quarters
Let y = the number of nickels
X + y = 62 x = 62 - y
.25x + .05y = 12.50 Multiply both sides of the equation by 100 to get rid of the decimal points.
25x + 5y = 1250
25(62-y) + 5y = 1250
1550 - 25y + 5y = 1250
-20y = -300
y = 15 nickels
x = 62 - y = 62 - 15
x = 47 quarters
<u>1/4 x = -2</u>
Multiply each side of the equation by 4 :
<em> x = -8</em>
Answer: I believe is 65/99
Step-by-step explanation: my teacher once told me when it has that infinite thing you place 99 under as a fraction [ however I'm not sure but I think thats right]
Answer:
x=20
m<B=92 degrees
m<C=40 degrees
Step-by-step explanation:
48+6x-28+2x=180
20+8x=180
8x=160
x=20
(6(20)-28)=92
2(20)=40
So, x=20, m<B=92 degrees and m<C=40 degrees
B and d because they cancel out x
Hope this helps
