The sum of Jahiem and his sister's age is 21. If Jahiem is 7 years older than his sister, write and solve a system of equations using ) to represent Jahiem's age and s
to represent his sister's age

Step-by-step explanation:

I think it is meant to use "j" for Jahiem's age.

so,

j + s = 21

j = s + 7

=> s + s + 7 = 21

=> 2s + 7 = 21

=> 2s = 14

=> s = 7

=> j = s + 7 = 7 + 7 = 14

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.

step-by-step explanation:

6mm^3 or .6cm^3

factor trees are nice.
