5x - x + 12 + 2x - 7 = 10

We're simply just trying to isolate x :)

However, we must first simplify the equation by adding like terms.

(5x - x + 2x) + (12 - 7) = 10

Simplify.

6x + 5 = 10

Then, we must subtract 5 from both sides.

6x = 10 - 5

Simplify.

6x = 5

Divide both sides by 6.

6x ÷ 6 = 5 ÷ 6

Simplify.

x = 5/6

B. x = 5/6

~Hope I helped!~

Combine like terms. Like terms are completely the same excluding coefficients.
6x+5=10

Subtract 5 from both sides
6x=5

Divide bith sides by 6
x=5/6

Final answer: B

A bus leaves Los Angeles at 8am moving northeast at 60 mph. Three hours later, a truck leaves the same place traveling 1 2/3 tim
love history [14]

Answer:

7.5 hours

Step-by-step explanation:

Using the variable 't' for time, you can set up an equation to find out how long it will take the truck to catch up to the  bus.  Since the bus is traveling at 60mph and the truck is traveling 1 2/3 times faster, we need to first find the rate of the truck:

1\frac{2}{3}=\frac{5}{3}

\frac{60}{1}*\frac{5}{3}=\frac{300}{3}=100mph

Using 't' and the knowledge that they will have traveled the same distance we the truck catches up to the bus and the fact that the truck left 3 hours later:

60t = 100(t - 3)  or 60t = 100t - 300

Solve for 't':  60t - 100t = -300 or -40t = -300  so, t = 7.5 hours

gregori [183]

Answer:

x=2,3

Step-by-step explanation:

(x- 2) (x - 3) =0

Using the zero product property

x-2 =0                 x-3 =0

x-2+2=0+2          x-3+3 =0+3

x=2                        x+3

A line passes through the points (6, 2) and (5, 0). What is its equation in slope-intercept form?
Makovka662 [10]

Answer:

y = 2x - 10

Step-by-step explanation:

y2 - y1/ x2 - x1

0 - 2 / 5 - 6

= 2

y = 2x + b

2 = 2(6) +b

2 = 12 + b

-10 = b

The equation is y = 2x - 10
