Answer:
C
Step-by-step explanation:
1. Let the shorter piece be x in. long
the longer piece will be x + 13 in. long
and the two pieces add up to be 47 in., so
x + ( x + 13 ) = 47
2x = 47 - 13
2x = 34
x = 17
the longer piece is x + 13 in. long,, or 17 + 13 = 30 in. long
2. number of dimes: x
number of quarters: y
x + y = 27....(1)
10x + 25y = 405...(2)
(1)*10: 10x + 10y = 270....(3)
(2) - (3):15y = 135
y = 9
plug y = 9 into (1), you will find that x = 18
so 18 dimes, 9 quarters
Y+6 should be the equation
Ben's age in x yeears=30+x
daniel's age in x years is 2+x
when will ben's age in x years be 3 times of daniel's age in x years
30+x=3(2+x)
30+x=6+3x
minus x both sides
30=6+2x
minus 6 both sides
24=2x
divide by 2 both sides
12=x
