$25. 25 x 3 is 75. Plus the 100 is 175. 200 - 175 is $25
Answer:
x=3 and y=1
Step-by-step explanation:
subtract equation 2 from 1
then (2x+3y) -(2x+y) =9-7
2x-2x+3y-y =2
2y=2 therefore y=1
substitute y value in 2x+y=7
2x+1=7
2x=7-1
2x=6
x=3
Answer:
3•10^3 is 3,000, so the answer is 9,000
Answer:
18
Step-by-step explanation:
