The sum of 5 and 8 is 13.
Unknown number is x
So 13x=42
x=4
Do a proportion
40/100= 8/x
8 x 100= 800
Cross multiply and divide
800 divided by 40= 20
So answer is 20
Answer:
The question = (7^3)*(7^x)
When multiplying two exponents with the same base, all you do is add the exponents together and keep the same base
Therefore,
(7^3)*(7^x) = 7^(3+x)
Step-by-step explanation:
7^3+x is the answer
Answer:
VP = 117 mm
Step-by-step explanation:
Corresponding sides of similar quadrilaterals are proportional.
VP/FD = BP/KD
VP = FD·BP/KD = (45 mm)·(78/30) . . . . multiply by FD; fill in the givens
VP = 117 mm
Answer:
w=3
Step-by-step explanation:
(w+3)x2=4w
2w+6=4w
2w+6-6=4w-6
2w-4w=4w-6-4w
-2w=-6
-2w/2 = -6/2
w=3
