Note that: EF + FG = EG

Plug in to corresponding places.

10x + 20 + 36 = 156

Simplify

10x + 56 = 156

Isolate the x. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.

10x + 56 (-56) = 156 (-56)

10x = 156 - 56

10x = 100

10x/10 = 100/10

x = 10

10 is your answer for x

if you practice a musical instrument each day for 2/3 of an hour how many hours of practice would you get in each week?

RideAnS [48]

In order to find the answer of the given problem above, we need to make the solution below:
Given: 2/3 of an hour = practice each day
2/3 of an hour is equivalent to 40 minutes
And per week, there are 7 days. So we will multiply 40 minutes by 7, and the result is 280 minutes. Since there are 60 minutes in an hour, we divide 280 by 60 and we get 4.67 hours. Therefore, each week, you would get 4.67 hours of practice on playing a musical instrument.

Answer:

x = $\frac{+}{-}$ 7

Step-by-step explanation:

$x^{2}$ = 49

$\sqrt{49}$ can equal 7 or -7

7 x 7 = 49. -7 x -7 = 49

Hatshy [7]

Answer:

$\boxed{ \text{B. 10 weeks, \$310 }}\\$

Step-by-step explanation:

We have two conditions:

$\begin{array}{lrcll}(1) & y & = & 25x + 60 & \\(2) & y & = & 30x + 10 & \\ & 25x + 60 & = & 30 x + 10 & \text {Set (1) = (2)} \\ & 50 & = & 5x & \text{Subtracted 25x from each side} \\& x & = & 10 &\text{Divided each side by 5} \\\end{array}\\$ $\\\boxed{ \textbf{The number of weeks is }x = 10}\\$

Bella: y = 25x + 60 = 25(10) + 60 = 250 + 60 = 310

Heather: y = 30x + 10 = 30(10) + 10 = 300 + 10 = 310
