Answer:
Thy bought 150 Sweatshirts (x) and 250 tshirts (y)
Step-by-step explanation:
35x + 25y = 11500
x + y = 400
-25 (x + y = 400) Multiply by -25 to get the y's to disappear when you add the two equations together
-25x - 25y = 10000
<u> 35x + 25y = 11500 </u>
10x =1500
x = 150
Plug 150 in either equation for x to find y
150 + y = 400
y = 250
Answer:
The answer for the problem would be -12
Step-by-step explanation:
(28+35) = 63
63-75= -12
Answer:
126
Step-by-step explanation:
set up a proportion, 59/140= x/300. Cross multiply: 140x= 17700. Then divide both sides by 140. the answer is 126.42857... ore rounded, 126.
Answer:
i think 9 but 6 could also be right
Step-by-step explanation:
18-12=6------18-3=15-------15-3=12-----------12-3=9
Answer:
Option C
Step-by-step explanation:
from the graph: y<4
so option A and B are wrong.
also if we choose any points in the area, always x will be bigger than y. so x>y
