Answer:

x=3

Step-by-step explanation:

Given: 15=7x-6

To solve this equation, we need to isolate x on one side of the equation algebraically. I see that we have like terms, but they are on opposite sides of the equal sign. Let's add 6 to both sides.

21=7x

To isolate x, divide both sides by 7.

x=3

Answer:

Step-by-step explanation:

the only thing we can say for sure is that JL is splitting the triangle and also its baseline IK in half.

so, both sides of the baseline must be equal :

3x = x + 6

2x = 6

x = 3

=> LK = x + 6 = 3 + 6 = 9

At Alan's auto shop, it takes him minutes to do an oil change and minutes to do a tire change. Let be the number of oil changes
kirill [66]

Complete question :

At Alan's auto shop, it takes him 9 minutes to do an oil change and 12 minutes to do a tire change. Let x be the number of oil changes he does. Let y be the number of tire changes he does. Using the values and variables given, write an inequality describing how many oil changes and tire changes Alan can do in less than an hour ( minutes).

Answer:

9x + 12y < 120

Step-by-step explanation:

Given that:

Time taken for oil change = 9 minutes

Time taken for tire change = 12 minutes

x = number of oil changes ; y = number of tire changes

Total hours = 1 hour = 60 minutes

Number of oil and Tyre changes possible in less than an hour

(Number of oil changes * time taken) + (number of tire changes * time taken) less than 60 minutes

9x + 12y < 120

What is the greatest common divisor of 33489, 3948, and 3949
storchak [24]

33489 = 32×612

3948 = 22×3×7×47

3949 = 11×359

GCD = 1

33489 / 1 = 33489

3948 / 1 = 3948

3949 / 1 = 3949
