Answer:

$\frac{53}{64}$

Step-by-step explanation:

$\frac{7}{8} - \frac{3}{64} \\ \frac{7 \times 8}{8 \times 8} - \frac{3}{64} \\ \frac{56}{64} - \frac{3}{64} \\ = \frac{53}{64}$

30 = -5(6b+6)<br> Please help

Serga [27]

Answer:

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

$30 = - 5(6b + 6)$

<u>let's simplify the parenthesis first ~</u>

$30 = - 30b - 30$

<u>now , bring the like terms at one side of the equation !</u>

$- 30b = 30 + 30$

$- 30b = 60$

<u>dividing</u><u> both sides of the equation by 30 ,</u>

$\\ \frac{ - \cancel{30}b}{\cancel{30}} = \cancel\frac{60}{30} \\$

$\dashrightarrow \: - b = 2 \\ \\ \dashrightarrow \: b = - 2$

hope helpful :)

Choose the equation that has solutions (5,7) and (8,13).

Alekssandra [29.7K]

<h2>Answer:y=2x-3</h2>

Step-by-step explanation:

$(x_{1},y_{1})$ is called solution of a equation if $(x_{1},y_{1})$ satisfies the equation.

Consider the equation $y=2x-3$ ,

For point $(5,7)$ ,

$LHS=y=7$

$RHS=2x-3=2(5)-3=10-3=7$

So, $RHS=LHS$

The point $(5,7)$ satisfies the equation.

For point $(8,13)$ ,

$LHS=y=13$

$RHS=2x-3=2(8)-3=16-3=13$

So, $RHS=LHS$

The point $(8,13)$ satisfies the equation.

So,both the points satisfy the equation $y=2x-3$

Am I correct if not help plzzz

Hey there!

You got the first part right where you added r to both sides. However, you need to make sure that you complete all actions on both sides, including canceling out parts of terms by division. The only thing you need to do is divide both sides by h instead of just the left. This will make your answer:

$y = \frac{b+r}{h}$

Hope this helped you out! :-)
