Answer: 38
Step-by-step explanation:
Step 1: use variables to replace the two numbers
the second number = x
six more than twice the second number = 2x + 6
Their sum is 120: 3x + 6 = 120
Step 2: solve the equation
3x = 114
x = 114/3 = 38
Step 3: check your answer (optional)
six more than twice 38 = 82
38 + 82 = 120
hope this helps
The equation in the problem solves the speed as 48.99 miles per hour. At this speed the car takes 100 feet to stop ( also shown in the equation as they replaced d with 100).
This means any speed below 48.99 miles per hour would stop before hitting the tree.
The fastest the car can go would be 48.98 miles per hour.
Justify by replacing s in the equation with 48.98 and solve for d:
48.98 ^2 = (sqrt( 30(0.8)d)
2399.04 = 24d
D = 2399.04/24
D = 99.96 feet
This is less than 100 feet so the car will not hit the tree.
Answer:
180
Step-by-step explanation:
1 foot a minute = 0.0113636364 miles a hour
15840 • 0.0113636364 = 180.000001
So pretty much just round down
The formula for volume is base×height×width
To prime factorization would be A: 2 X 3 X 5 X 7
Because if your do 2 X 3 it would be 6
Then you do 5 X 7 it would be 35
And 6 X 35 would be 210
AND THAT IS FACTORING THE PROBLEM
