Answer: B, E
Step-by-step explanation:
Answer:
(1/2,4)
Step-by-step explanation:
First, determine y in first equation: 2x+y=5 or y=5-2x
replace value of y determined in first equation (5-2x) into 2nd equation
4x-3(5-2x)=-10
4x-15+6x=10
10x=5
x=1/2
put value of x into either equation to solve for y so
2(1/2)+y=5
1+y=5
y=4
answer: x=1/2, y=4
check answer by substituting x and y into either equation:
4x-3y=-10
4(1/2)-3(4)=-10
2-12=-10
-10=-10
or
2x+y=5
2(1/2)+4=5
1+4=5
5=5
So if 18 + x =43, then what you need to do is
18 + x =43
-18 -18
——————
x = 25
because whatever you do to one side, you need to do to the other
Answer:
10
Step-by-step explanation:
The volume of a cube is equal to its (side length)^3
so s^3 = 1000
![s=\sqrt[3]{1000} =10](https://tex.z-dn.net/?f=s%3D%5Csqrt%5B3%5D%7B1000%7D%20%3D10)
D 1/7 because only one chair is sort. Out of 7 only one person will have the short chair. 1/7 is the answer. trust me
