(4x - 10) + (12x + 6) = 68
16x - 4 = 68
16 x = 72
x = 4.5
So, 12 (4.5) + 6 = 60
14 weeks is the answer
60+ 30w = 480
-60 -60
30w = 420
Divide by 30 on each side
w = 14
Answer:
Find the volume of the rectangular prism and
divide by the volume of the cube.
Volume of cube = side measure ^3
Cube = (1/8)3 = 1/512
Volume of prism = Ixwxh
Prism (1/4)(1/2)(3/8) =3/64
3/64/1/512
3/64 x 512/1
3x 512/64
1536/64

Answer:
35% of the sixth grade is in the chess club
Step-by-step explanation:
if there are 100 students consider that as 100%
20 is a fifth of 100
20 x 5 =100
since 7/20 is a fraction you multiple the numerator (7) with the same number you multiplied to the denominator (20) which is 5.
7 x 5 = 35
35/100 = 35%
D = x
E = .5x
F = 2x-2
(x)+(.5x)+(2x-2)=180
3.5x-2=180
3.5x=182
x=52
F = 2(52)-2 = 102 degrees
