They are simple linear equations with one unknown, lets tackle them, one step at the time solving for the unknown:
4x - 2(x - 5) = x + 13
4x - 2x + 10 = x + 13
2x + 10 = x + 13
2x - x = 13 - 10
x = 3
that is the solution.
3(6 - x) - 4 = 5x + 2(7x + 3)
18 - 3x - 4 = 5x + 14x + 6
14 - 3x = 19x + 6
14 - 6 = 19x + 3x
8 = 22x
x = 8/22 = 4/11
Answer:
Hey there!
Angela will have 7+2, or 9 cups of rice.
Let me know if this helps :)
Answer:
Step-by-step explanation:
difference of x-coordinates = 4-(-6) = 10
difference of y-coordinates = -1-9 = -10
partition the differences into a ratio of 1:4
10 × 1/(1+4) = 2
-10 × 1/(1+4) = -2
(-6+2,9-2) = (-4,7)
.25 or 1/4
How:
2^4=16
2^-6=<span>.015625
16*.015625 = .25</span>
