Answer:
5x?=30 and ?x5=30
Step-by-step explanation:
First of, these 2 are both the same, and the communitive property applies to both.
The question example is in division, since the communitive prop. doesn't apply on division, it would be almost impossible to find another answer in division form. 5x? Is asking 5 times what equals thirty, so we are using what we know to figure it out. Sorry, I can't provide a good explanation :<
62+92 is 154. 180- 154 is 26
Answer:
0.03 seconds
Step-by-step explanation:
10,000km = 300secs
1km = x seconds
Cross multiply the equation
10,000x = 300
Divide both sides by 10,000
<u>1</u><u>0</u><u>,</u><u>000x</u> = <u>3</u><u>0</u><u>0</u>
10,000 10,000
x = 0.03 seconds
Answer:
-6 = x
Step-by-step explanation:
3 sqrt (5x-4) = 3 sqrt (7x+8)
Divide each side by 3
3/3 sqrt (5x-4) = 3/3 sqrt (7x+8)
sqrt (5x-4) = sqrt (7x+8)
Square each side
(sqrt (5x-4))^2 = ( sqrt (7x+8) )^2
5x-4 = 7x+8
Subtract 5x from each side
5x-5x-4 = 7x-5x+8
-4 = 2x+8
Subtract 8 from each side
-4-8 = 2x+8-8
-12 = 2x
Divide by 2
-12/2 = 2x/2
-6 = x
