I don't think you have the correct options. 9/12 + 6/12 = 15/12. To simplify, you divide each value by 3 and get 5/4, which, as a mixed number, would be 1 1/4, and neither 5/4 or 1 1/4 is an option. I hope this helps!
Answer:
x = .98
Step-by-step explanation:
-.5(17x - 24) = 3.4x - 6 + 6.3x
-8.5x + 12 = 9.7x - 6
-18.2x = -18
18.2x = 18
x = .98
Answer:
Perimeter: 2(3x+6)+ 2(2x-4)
X=9
Step-by-step explanation:
In order to create the expression you just have to remember that the perimeter of a rectangle equals 2 bases plus 2 sides, so the expression would be:
Perimeter: 2(heights)+ 2(bases)
Perimeter: 2(3x+6)+ 2(2x-4)
IN order to solve for X we just have to insert the value of perimeter, which is 94:
Perimeter: 2(3x+6)+ 2(2x-4)
94=2(3x+6)+ 2(2x-4)
94= 6x+12+4x-8
94=10x+4
94-4=10x
x=90/10
x=9
So the value of x would be 9.

Answer:
z=10
Step-by-step explanation:
We know that the ratio 7:21 is equal to the ratio of 10:3z.
Let's model that in proportions:
7 10
- = -
21 3z
Now that the equation is in proportional form, we can cross-multiply to find the value of z.
7 * 3z = 21 * 10 - Multiply both sides
21z = 210 - Divide both sides by 21
z=10
The answer is z=10.
