Answer:

Step-by-step explanation:

$let \: the \: number = y \\ from \: the \: queston \: \frac{3}{8} \: of \: y = 24 \\ \frac{3}{8} \times y = 24 \\ \frac{3y}{8} = 24 \\ 3y = 8 \times 24 \\ 3y = 192 \\ divide \: bothsides \: by \: 3 \\ \frac{3y}{3} = \frac{192}{3} \\ y = 64 \\ therefore \: \: the \: number \: is \: 64$

Answer:

The number is 32

Step-by-step explanation:

Let the number be x

$\frac{3}{4} \times x = 24 \\ \frac{3x}{4} = 24 \\ cross \: multiply \\ 3x = 24 \times 4 \\ 3x = 96 \\ x = \frac{96}{3} \\ x = 32$

Answer:

The solution to the system of equations be:

$x=3,\:y=-1$

Hece, option B is correct.

Step-by-step explanation:

Given the system of equations

$\begin{bmatrix}x-3y=6\\ 2x+2y=4\end{bmatrix}$

Multiply x − 3y = 6 by 2: 2x-6y=12

$\begin{bmatrix}2x-6y=12\\ 2x+2y=4\end{bmatrix}$

$2x+2y=4$

$-$

$\underline{2x-6y=12}$

$8y=-8$

so the system of equations becomes

$\begin{bmatrix}2x-6y=12\\ 8y=-8\end{bmatrix}$

Solve 8y = -8 for y

$8y=-8$

Divide both sides by 8

$\frac{8y}{8}=\frac{-8}{8}$

$y=-1$

$\mathrm{For\:}2x-6y=12\mathrm{\:plug\:in\:}y=-1$

$2x-6\left(-1\right)=12$

$2x+6=12$

subtract 6 from both sides

$2x+6-6=12-6$

$2x=6$

Divide both sides by 2

$\frac{2x}{2}=\frac{6}{2}$

$x=3$

Therefore, the solution to the system of equations be:

$x=3,\:y=-1$

Hence, option B is correct.

A runner ran at a steady rate, stopped to retie their shoes, and then ran at a steady rate again, this time slower than they ran

daser333 [38]

The First Graph represents the situation.
The runner goes a lot of distance in a short amount of time (Demonstrated by the steep incline of the first portion). When the runner is tying their shoe, the distance remains the same, thus eliminating the second graph and the last graph because the last graph doesn't show the beginning of the problem. Finally, we know that the runner is slower after tying their shoe, this means the incline of the line would be far less as steep (Meaning the slope would be smaller). The only graph that depicts all of these, is the first one.

I Hope this Helps!
