For 1 kilometer, it is 100,000 Centimeters.
Answer:
The original price was $30
Step-by-step explanation:
H = Alice's home runs
p = Peter's home runs
p = 2(h - 6)
p + h = 18
Simplified:
p = 2h - 12
p - 2h = -12
p + h = 18
Solve simultaneously:
p - 2h = -12 ...1
p + h = 18 ...2
1 - 2:
-3h = - 30
h = -30/-3
h = 10
Substitute into 2:
p + h = 18
p + 10 = 18
p = 18 - 10
p = 8
Therefore, Peter hit 8 home runs and Alice hit 10 homeruns.
Answer:
$19
Step-by-step explanation:
the following equations can be determined from the question
5j + 2s = 208 equation 1
3j + 4s = 178 equation 2
where j = jeans
s = sweatshirts
simultaneous equation would be used to determine the values
Multiply equation 1 by 2
10j + 4s = 416 equation 3
subtract equation 2 from 3
7j = 238
j= $34
substitute for j in equation 1
5(34) + 2s = 208
2s = 38
s = $19
