You guys are Smart, Answer me this. But I need It fast-
miss Akunina [59]

Answer:

E = 58

F = 32

G = 90

Step-by-step explanation:

3x + 31 + 5x -13 + 90 = 180

3x + 31 + 5x -13 = 90

8x = 90 - 31 + 13

8x = 72

x = 72 / 8

x = 9

E = 3(9) + 31 = 27+31 = 58

F = 5(9)-13 = 45 - 13 = 32

G = 90

The circle graph shows the percentage of time Jacob spent on homework in each subject last week.Time Spent on Homework12.5%25%ar
Goshia [24]

We are given a circle graph that shows the time spent on homework last week.

Jacob spent a total of 16 hours doing homework.

The time spent on doing science homework is given by

\begin{gathered} t_{\text{science}}=25\%\: of\: 16 \\ t_{\text{science}}=\frac{25}{100}\: \times\: 16=4\: \text{hours} \end{gathered}

The time spent on doing band practice is given by

\begin{gathered} t_{\text{band}}=12.5\%\: of\: 16 \\ t_{\text{science}}=\frac{12.5}{100}\: \times\: 16=2\: \text{hours} \end{gathered}

The difference between the time spent on science homework and band practice is

difference=t_{\text{science}}-t_{\text{band}}=4-2=2\: \text{hours}

Therefore, Jacob spent 2 more hours on science homework than band practice.

Find the equation for the line passing through the point (−1,1) ( − 1 , 1 ) and parallel to the line whose equation is y=2x+12.
tekilochka [14]
So, parallel lines have the same slope, therefore a parallel line to 2x+12, will have the same slope as that one, so which is it?   \bf y=\stackrel{slope}{2}x\stackrel{y-intercept}{+12}

so, we're really looking for the equation of a line whose slope is 2, and runs through -1,1.

\bf \begin{array}{lllll}&#10;&x_1&y_1\\&#10;%   (a,b)&#10;&({{ -1}}\quad ,&{{ 1}})&#10;\end{array}&#10;\\\\\\&#10;% slope  = m&#10;slope = {{ m}}= \cfrac{rise}{run} \implies 2&#10;\\\\\\&#10;% point-slope intercept&#10;\stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-1=2[x-(-1)]&#10;\\\\\\&#10;y-1=2(x+1)\implies y-1=2x+2\implies y=2x+3

Solve the system of equations and choose the correct answer from the list of options. d + e = 15 −d + e = −5 Label the ordered p
Shtirlitz [24]

Answer:

3) (5, 10)

Step-by-step explanation:

d + e = 15

-d + e = -5

e = -5 + d

substitude e for -5 + d

d + -5 + d = 15

2d = 10

d = 5

figure out e

5 + e = 15

e = 10
