Answer:
10 songs
Step-by-step explanation:
20 + 1x = 3x
20 = 2x
10 = x
—
20 + 1(10) = 3(10)
20 + 10 = 30
30 = 30
Answer:
- 102 + (3x +2) = 180 . . . . equation to solve
- x = 25 1/3 . . . . . . . . . . . . value of x
Step-by-step explanation:
It can be helpful to draw a diagram of a parallelogram ABCD and identify the angles in the problem statement. You will find they are adjacent angles.
Adjacent angles in a parallelogram are supplementary, so the sum of the given angle measures will be 180°.
102 + (3x +2) = 180 . . . equation used to solve for x
3x = 76 . . . . . . . . . . . . . subtract 104
x = 76/3 . . . . . . . . . . . . divide by 3
x = 25 1/3 . . . the value of x
Answer:
She needs 168 more cels to draw to complete the film sequence
Step-by-step explanation:
120 Cells in 5 seconds
You want 12 seconds.
Ratio (Proportion)
120:5
Lets find the "unit rate" of the proportion.
120/5 = 24
So the unit ratio is 24:1
Now, we can deduce to it being:
120:5
240:10
264:11
288:12
She has 120 done.
So, 288-120 = 168.
She needs 168 more cels to draw to complete the film sequence
Answer:
56 - 2b = a
Step-by-step explanation:
Step 1:
60 + 2a - 4 = 2b + 3a
Step 2:
56 + 2a = 2b + 3a
Step 3:
56 = 2b + a
Answer:
56 - 2b = a
Hope This Helps :)
