21x + 84 + 12x - 16
33x + 68
The correct answer is 1.) 33x + 68.
Hope this helps!
Since both angle are congruent (equal/same), which means that both side is equal to 40 degrees, we will put the equation like this:
5x - 5 = 40
Now we’ll solve for x:
5x - 5 = 40
+ 5 + 5 (Add 5 to both sides)
5x = 45
—- —— (Five both side by 5)
5 5
x = 9
Now we left with x, so x is equal to 9.
The answer is 29% first you subtract the first number by the second number then make a fraction with the difference and the second number then make a decimal and make a percent out of that decimal
6 feet:10 hours
multiply by 1.5 on both sides
9 feet:15 hours
answer: 9 ft
The circumference of the top of the cake is 
in.
It sounds like the baker is trying to line the circumference with cherriesto fit as many as possible along the border, like in the picture I've attached below.
This comes down to dividing the cake's circumference by the diameter of each cherry:
or about 39 cherries, making the answer D.
