5 0

Answer: 172

Explanation:

<u>Mystery</u>          <u>Science Fiction</u>          <u>Biographies</u>

   4x                  3x

                                       4y                       5y

Science Fiction = 48

3x = 48      ⇒    x  = 16          

4y = 48      ⇒     y  = 12


Mystery: 4x   = 4(16)   = 64

Biographies: 5y   = 5(12)   = 60


Mystery + Science Fiction + Biographies = Total

     64     +          48            +         60        = Total

                                                         172    = Total

Y=2x+5 (B) You have to bring 8x to the other side of the equal sign (by addition) and divide both sides by 4.

Please answer this multiple choice question CORRECTLY for 30 points and brainliest!!
JulijaS [17]

Solve the inequality for x:

5x - 3 ≤ 7x +7

Subtract 7x from each side:

-2x -3 ≤ 7

Add 3 to each side:

-2x ≤ 10

Divide both sides by -2, also when dividing  both sides of an inequality you flip the direction of the inequality sign:

x ≥ -5

The dot will be on -5, because the inequality includes equal to, the dot is solid and is greater than, the arrow will point to the right.

The correct answer is D.

In which quadrants do solutions for the inequality y is less than or equal to two sevenths times x plus 1 exist?
hram777 [196]

Answer:

y will be in every single quadrant

Step-by-step explanation:

So we have the equation y\leq \frac{2}{7} x+1  first we will have to look at the equation. It says that y is less than or equal to \frac{2}{7} x+1 since y is less than \frac{2}{7} x+1 the only place the shaded area where y can be is under the line that is drawn be the equation. When the equation is graphed the y-intercept will be on positive 1 it since slope is rise over run it will look something like the file attached to this. so under the line you can see every single quadrant so that is why it would be that way
