25mm is the answer if its not tell me
Solve for y for both equations then equate and solve:
5x + 9y = 160
9y = 160 - 5x
y = 160/9 - 5/9x
9x + 8y = 202
8y = 202 - 9x
y = 202/8 - 9/8x
160/9 - 5/9x = 202/8 - 9/8x (common denominator is 72)
1280/72 - 40/72x = 1818/72 - 81/72x
1818/72 - 1280/72 = 81/72x - 40/72x
538/72 = 41/72x
538 = 41x
538/41 = x
x = 13 5/41
0.5,0.55,0.005,0.505 is my answer
please can i have a brainliest
Answer:
5w^2 + 6w - 32
Step-by-step explanation:
Subtract as needed and combine like terms
(-2w^2 + 6w - 19) - (-7w^2 +13) dont forget to distribute the negative
so you get this:
-2w^2 + 7w^2 = 5w^2
6w
-19 - 13 = - 32
your answer is 5w^2 + 6w - 32
hope this helps :)
Answer $9.00 per pound for almonds
Reason
First, 70# x $3.50 = $245 of peanuts
Second, $515 total cost - $245 of peanuts = $270 of almonds
Third, we know 100# - 70# peanuts = 30# of almonds
Last, $270 cost of almonds divided by 30# of almonds = $9.00 per pound for almonds
