Answer: -44

Step-by-step explanation: PEMDAS(Parenthesis; Exponent; Multiply; Divide; Add; Subtract)

First you multiply the seven with the other seven to get 49. The problem will look like this: (-3) + 8 - 49. Now just add the -3 and 8. You'd get 5.

Now the problem looks like this: 5 - 49. And you then get -44.

108 = -2(-5 - 7b) What does b equal?
mario62 [17]

Answer:

b = 7

Step-by-step explanation:

108 = -2(-5 - 7b)

Distribute -2 to the terms inside the parenthesis:

108 = 10 + 14b

Subtract 10 from both sides of the equation to isolate 14b:

108 - 10 = 10 + 14b - 10

98 = 14b

Divide 14 on both sides of the equation to solve for b:

\frac{98}{14}  = \frac{14b}{14}

7 = b

What is the value of x?
lilavasa [31]

The little rectangle in the top right means the angle is a right angle which equals 90 degrees.

This also means all the other angles are also 90 degrees.

Solve for x:

2x+8 = 90

Subtract 8 from both sides:

2x = 82

Divide both sides by 2:

x = 82/2

x = 41

Please help me gow to this bro , im confused
Airida [17]
Ok so remember that a circle is 360 degrees and a line is 180 degrees
so

IKJ
ok so we see that we have a triangle
to find the internal angles (which add to 180)
we do, opposite angles are equal
JIK=59
also CJI+KJI=180 so 132+KJI=180, KJI=48
so
59+48+IKJ=180
73=IKJ




HIB
we can assume that AB is paralell to CD
so therefor IJK=HIB=48 (from previous question)

EIJ is adding to EIH to get 180
EIJ+59=180
EIJ=121

AIK=AIJ+JIK
JIK=59
AIJ=HIB=48
AIK=59+48=107


IKJ=73
HIB=48
EIJ=121
AIK=107

What’s the answer to this

Answer:

slope: -1/3

you find the slope by taking one point (0,2) and then finding the change in y over the change in x from it to another point (3,1) :

1-2/(3-0) = -1/3
