Answer:
when z=3 or 5 , values of x is ; 6 or 10.
I think that there is a lack of information or misspelling in the question.
Step-by-step explanation:
4x-3=6x-4z-3
4z=2x
2z=x
z=3 => x=6
z=5 => x=10
Answer:
x = 2.2
Step-by-step explanation:
-15 + 12x = 5x + 7 - 3x
Combine like terms
-15 +12x = 2x +7
Subtract 2x from each side
-15 +12x -2x = 2x-2x +7
-15 +10x = 7
Add 15 from each side
-15+15 +10x = 7+15
10x = 22
Divide each side by 10
10x/10 = 22/10
x = 2.2
Answer:
Step-by-step explanation:
1. -3( x - 4) = 2x + 4 - x
-3x + 4 = x + 4
4 = 2x + 4
2x = 0
x = 0
2. 4 + 2 (x - 2) = 2 (x - 1) + 2
4 + 2x - 4 = 2x + 2 + 2
2x = 2x + 4
x = 4
3. 3(x - 4) = 2x - 7 + x
3x - 12 = 3x - 7
x = 5
4. 4x + 15 = 3(x + 5)
4x + 15 = 3x + 15
x = 0
5. 2(x - 3)
for the rest i'm confuse what it is suppose to be
Answer:
2)16.5
Step-by-step explanation:
step1:v/2.2 -0.1=7.4
add 0.1 on both sides
step2:v/2.2=7.5
multiply by 2.2 on both sides
step3:v=16.5
24 cookies
dean ate 8 cookies
elise ate 4 cookies
clark ate 6 cookies
Step-by-step explanation:
i am pretty sure this is correct
make a diagram of a circle with twelve spots
change 1/3 to 4/12, so color in 4 spots for dean
multiplie 1/4 times 8/12 ( the remaining spots), color in that number of spots for elise
do the same with 1/2, color in the amount of spots for clark
you will have 3 spots left, meaning each spot is worth 2 cookies
multiplie the number of spots times two to get your answer for each person
