Answer:
23 yards
Step-by-step explanation:
During a test flight, Jeri's rocket reached a height of 18 yards. This was 7 yards less than the height of Devon's rocket. Write and solve a subtraction equation to find the height of Devon's rocket.
Let us represent the height of Devon's rocket = x
18 yards = x - 7 yards
x = 18 yards + 7 yards
x = 23 yards
The height of Devon's rocket = 23 yards

Answer:
The probability of a student receiving a C in the course is p=0.3.
Step-by-step explanation:
We have a absolute frequency for each of the grades (A to F), of a total of 300 course tests.
It is assumed that this sample gives a dood estimation of the distribution of the grades. Then, we can estimate the probability of obtaining a C in the course usign the relative frequency for C.
The relative frequency is calculated as the division between the absolute frequency (in this case, 90 for a C grade) and the size of the sample (in this example, 300).
Answer:
8x + 13
Step-by-step explanation:
The perimeter is the sum of the 5 sides of the polygon, that is
perimeter = x + 5 + 3x + x + x + 5 + 2x + 3 ← collect like terms
perimeter = 8x + 13
