Answer:
minus it
Step-by-step explanation:
So 3 apples=6 dollars
therefor if we divide both sides by 3
1 apple=2 dollares
so therfor for every 1 apple, you pay 2 dollars
so if 12 apples
12 times 2=24
24 dollars
anonther way is
3 apples=6 dollars
6 apples=12 dollars
9 apples= 18 dollars
12 apples= 24 dollars
Assuming the spaces mean plus (+):
2(3y+5) = 3(5y+13)
6y+10 = 15y+39
10 = 9y+39
9y = -29
Therefore, y = -29/9 or -3.22
A good ol’ copy and paste into the Google calculator. The answer you’re looking for is 8.5354363e+8 (I copy and pasted that too).
Let x = cups of 11% wheat, and y = cups of 63% wheat
He wants 12 cups in total, so we need:
x + y = 12
These 12 cups need to have 50% wheat, which means we are looking at 12*.5 = 6 cups of wheat in total, so our second equation is:
.11x + .63y = 6
We have two equations and two variables. So we can solve by using any means you want. I used substitution:
x = 12 - y
.11(12-y) + .63y = 6
1.32 -.11y + .63y = 6
.52y = 4.68
y = 9
Which means x = 3
Thus, 3 cups of 11% and 9 cups of 63%.
