Solve for j.-13j - 20 = -8j + 20​

Mathematics
1 answer:
aleksley [76]3 years ago
8 0

Answer:

j = -8

Step-by-step explanation:

-13j - 20 = -8j + 20​

Add 13 j to each side

-13j+13j - 20 = -8j+13j + 20

-20 = 5j+20

subtract 20 from each side

-20-20 = 5j +20-20

-40 = 5j

Divide by 5

-40/5 = =5j/5

-8 =j

Alex Ar [27]

Answer: C

Step-by-step explanation:

We know that \angle AHB=90^{\circ}, and thus by the exterior angle theorem,

90^{\circ}+\alpha=4\alpha\\\\90=3\alpha\\\\\alpha=30^{\circ}

Thus, \angle CAB=2\theta=\boxed{60^{\circ}}

Solve for the equation 4a-8=28
hoa [83]
4a-8=28
add 8 to both sides to start to isolate the variable (a)
-8+8 cancels each other out
28+8=36
4a=36
to completely isolate the variable divide both sides by 4
4a÷4=a
36÷4=9
a=9

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Find endpoints from graph</em>

Point (-3, -3)

Point (4, 2)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>

  1. Substitute in points [Distance Formula]:                                                         \displaystyle d = \sqrt{(4- -3)^2+(2- -3)^2}
  2. [√Radical] (Parenthesis) Subtract:                                                                    \displaystyle d = \sqrt{7^2+5^2}
  3. [√Radical] Evaluate exponents:                                                                       \displaystyle d = \sqrt{49+25}
  4. [√Radical] Add:                                                                                                  \displaystyle d = \sqrt{74}
