Answer:
38
Step-by-step explanation:
We have to substitute x with 2 and y with 4
when the sign of a operation is not expressed it means that the operation is a
multiplication
So we have
3*2 + 2*(4)^2
6 + 2*(16)
6 + 32
38
You would keep the first fraction the same , turn the division sign into a multiplication sign , and flip the 2nd fraction upside down.
10/14 ÷ 7/16
10/14 x 16/7= 80/49 = 1 31/49
Answer:
19. A
20. A
Step-by-step explanation:
19. tan(53)=15/x
x(tan(53))=15
x=15/(tan53))
x=11.3 feet
20. tan(60)=12/x
x(tan(60))=12
x=12/(tan(60))
x=6.93, or 4sqrt3
The answer is c
25/5 is 5
So 5>4
False
-3 is not greater than positive 3
