What do you mean? Question not clear.
Answer:
3x(x - 2)
Step-by-step explanation:
Given
3x² - 6x ← factor out the common factor 3x from each term
= 3x(x - 2)
Answer:
x = 9 and y = -7
Step-by-step explanation:
given:
using substitution method:
2(-4y - 19) + 2y = 4
-8y - 38 + 2y = 4
-6y = 42
y = -7
Solve for x:
x = -4(-7) - 19
x = 28 - 19
x = 9
Answer:
7:15 am
Step-by-step explanation:
1. Add the times together by finding a common denominator
3/4 = 9/12
1/6 = 2/12
1/12 = 1/12
1/4 = 3/12
9/12 + 2/12 + 1/12 + 3/12 = 15/12
It took him 15/12 of an hour in total.
2. Convert to hours
15/12 = 1 3/12
3/12 = 1/4
1/4 of an hour is 15 minutes.
I took him a total of 1 hour and 15 minutes.
3. Subtract 1 hour and 15 minutes from 8:30
8:30 - 1:15 = 7:15
10-3 2/5
First I'll do it with decimals and then fractions :)
10-3 2/5 is the same as 10-3.4 which is 6.6.
With fractions you can do:
10-3 2/5 is the same as 10-3 4/10 and also 100/10-34/10
100-34=66 so it would be 66/10 or 6 6/10 simplified to 6 3/5
Hope this helps :)
