Answer:

x + x + x + x is the same as 4x

because its "x four times"

5x and x+5 are not the same because x+5 in not "x five times"

5x is 5 multiplied by x.

x + 5 is 5 added to x.

Test worth 75 points ; test score of 96%
vfiekz [6]
Presuming the question is "How many points did he miss", you would find the solution by multiplying the amount of possible points by the test score as a fraction. 96% is the fraction \frac{96}{100}. Therefore, you get the equation 75*\frac{96}{100}. This is equal to 72, so he missed 3 points, or 75-72 points. 

He missed 3 points.

Someone help pretty please!
Nonamiya [84]
The answer is choice B
y > (2/3)x + 1

The boundary line is the equation y = (2/3)x + 1 which can be found through the slope formula to get m = 2/3. Then you use one of the two points on the line to find b = 1. 

The equal sign in y = (2/3)x + 1 changes to a "greater than" sign to indicate two things
A) The shaded region is above the boundary line
B) The boundary line itself is a dashed line to indicate "no solution points on this line"

Simplify to create a equivalent expression.
Ratling [72]

Answer:

\boxed{\bold{66k+9}}

Explanation:

Expand \bold{5\left(10k+1\right): \ 50k+5}

= \bold{50k+5+2\left(2+8k\right)}

Expand \bold{2\left(2+8k\right): \ 4+16k}

= \bold{50k+5+4+16k}

Simplify \bold{50k+5+4+16k: \ 66k+9}

= \bold{66k+9}
