Answer: B) 4.90

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Katrina: 69.75 inches tall
Allison: 64.85 inches tall.

Since Katrina is taller than Allison, to calculate the how many inches taller is Katrina than Allison, we have to subtract Allison’s height to Katrina’s height:

Mathematically speaking:

69.75 -64.85 = 4.9 inches.

3/4(12x−8)+3=10−1/2(6x+2)

Aleonysh [2.5K]

Answer:

$x=1$

Step-by-step explanation:

$\frac{3}{4}(12x-8)+3=10-\frac{1}{2}(6x+2)$

$(9x-6)+3=10-(3x+1)$

$9x-6+3=10-3x-1$

$9x-3=9-3x$

$9x=12-3x$

$12x=12$

$x=1$

Help with both questions offering 10 points

Alexandra [31]

Answer:

$\:\mathrm{First\: problem:\:}-2,\\\:\mathrm{Second\: problem:\: }-3$

Step-by-step explanation:

The slope of a line passing through points $(x_1, y_1)$ and $(x_2, y_2)$ is:

$m=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}$

Plugging in any two points in the table we have:

First problem:

$m=\frac{1-5}{2-0}=\frac{-4}{2}=\fbox{$-2$}$

Second problem:

$m=\frac{-1-5}{2-0}=\frac{-6}{2}=\fbox{$-3$}$
