1/5 i hope it helps. We knows this because 20 times 5 is 100. 5 times 2 is 10.
$22 = 88 quarters
One dollar = Four quarters
22 x 2 = 44
22 x 3 = 66
22 x 4 = 88
X = (1/2)y + 6
x + y = 21
Substitute (1/2)y + 6 as x into the equation x + y = 21 since x = (1/2)y + 6.
[(1/2)y + 6] + y = 21
0.5y + 6 + y = 21
1.5y = 15
y = 10
Same thing, now substitute 10 as y in the other equation.
x + y = 21
x + (10) = 21
x = 11
160 inches... I am 98% sure I am correct
Answer:
10^5 = 100.000
Step-by-step explanation:
We know that 10^5 = 10 * 10* 10 * 10 * 10 = 100.000.
So, we have that 10^5 = 100.000
