Answer:
e = -2
Step-by-step explanation:
9e-7=7e-11
Subtract 7e from both sides
9e-7e -7=7e -7e-11
2e -7 = -11
Add 7 to each side
2e -7+7 = -11+7
2e = -4
Divide each side by 2
2e/2 = -4/2
e =-2
the corner angle=90⁰ 45+45+90=180
Answer:
3x - 8
Step-by-step explanation:
the factors of the following equation
are:

If you look the equation you can notice that you don´t have a term like -48x or 48x, so the factors must have a positive and negative sign.
Remember first you need to multiply each segment and finally add.
= 
<span>–122 < –3(–2 – 8x) – 8x
-122< 6 + 24x - 8x
-122 < 6 + 16x
-122 - 6 < 16x
-128<16x
-128/16<x
-8<x
x>-8
answer is </span>B. x > –8
Answer:
I dont know what you are supposed to answer with but I'll try to help you out. I take it that you have to find the letter ex. the letter <em>d</em> in 1/<em>2d</em> = 7. What you have to do is to get the <em>d</em> by itself and in order to do that you must move the 1/2 over to the 7. So what you would have to do is take the fraction that has the letter on it and move it to the whole number side or the side without the letter but without moving the <em>d</em><em>.</em><em> </em>The <em>d</em> stays on one side while the other numbers are on the other side. When you move the 1/2 over it should look like this sort of due to the limitations of only being able to use text: <em>d</em> = 7 ÷ 1/2. Now after that you have to divide 7 by 1/2 or .5 for question 13 in this instance. Your answer for 13 should be this: <em>d</em><em> </em><em>=</em><em> </em><em>4.5</em><em> </em><em> </em><em> </em><em> </em><em> </em><em>Make</em><em> </em><em>sure</em><em> </em><em>to</em><em> </em><em>show</em><em> </em><em>all</em><em> </em><em>your</em><em> </em><em>work</em><em> </em><em>just</em><em> </em><em>in</em><em> </em><em>case.</em>
13. <em>d</em> = 4.5
14. 18 = <em>f</em>
<em>1</em><em>5</em><em>.</em><em> </em><em>-</em><em>9</em><em> </em>=<em> </em><em>s</em>
<em>1</em><em>6</em><em>.</em><em> </em>-24 = <em>r</em>
17. 0.125 = <em>y</em>
18. -3 = <em>v</em>
Hope I could help as I am also a fellow 9th grader
