Answer:
5
Step-by-step explanation:
First multiply inside of the parenthesis with 3 then add the like terms
3x + 6 - 6 = 15 ➡ 3x = 15 divide both sides with 3 and x = 5
Answer:
3 3/7 minutes
Step-by-step explanation:
This calculated using the formula:
1/x + 1/y = 1/n
Where
x = Number of minutes it took Ann to walk = 6 minutes
y = Number of minutes it took Alek to walk = 8 minutes
n = Number of minutes it would take An and Alek to reach the starting point at the same time
1/6 + 1/8 = 1/n
Lowest Common Denominator = 24
4 + 3/24 = 1/n
7/24 = 1/n
Cross Multiply
7n = 24
n = 24/7
n = 3 3/7 minutes
It would take them 3 3/7 minutes to reach the starting point at the same time.
Answer:
Slope is y2-y1/x2-x1
Let’s make the point (-3,18) our x1 and y1 and make the point (12,-15) our x2 and y2.
-15-18/12-(-3)
-33/15
-11/5 would be your answer.
Hope I helped!
