Answer:
x = 133/4 or x = 33.25 decimal
Step-by-step explanation:
Solve for x:
7 - 4 x = -126
Subtract 7 from both sides:
(7 - 7) - 4 x = -7 - 126
7 - 7 = 0:
-4 x = -7 - 126
-7 - 126 = -133:
-4 x = -133
Divide both sides of -4 x = -133 by -4:
(-4 x)/(-4) = (-133)/(-4)
(-4)/(-4) = 1:
x = (-133)/(-4)
Multiply numerator and denominator of (-133)/(-4) by -1:
Answer: x = 133/4
Answer:

5
Step-by-step explanation:
Start by multiplying 2 and -4/5 as fractions
2 -4 -8
------ x ------ = -------
1 5 5
Then multiply 6 and 1/3 as fractions
6 1 6 2
------ x ------ = ------- = -----
1 3 3 1
Lastly,add the two results after converting 2/1 to 10/5 to use the Greatest Common Factor so you can add.
-8 10 2
------- + ------ = -------
5 5 5
Slope intercept form is y=mx+b m=slope, b=y-intercept
13-18 Solve the equations so that y is by itself.
19-21 Plug in the slope, and plug in the points for x and y, then solve for b.
22 Find the slope, then plug in the points for x and y, and solve for b.
23 There is no slope, so it is just y=-5
24 Slope is zero, so it is just x=-4

Answer:
The radius will be half of your diameter so,
since 26 is your diameter half of that is = 13 is your new radius.
Now finding the area:
13^2 = 169
169 x 3.14 = 530.66 cm2 is your area.
Formula of an area of a circle:
πr^2
pi(3.14 or 22/7 depending on whatever they tell you to use for pi) x radius being squared
Answer:
Step-by-step explanation:
simplify by combining like terms
4x - 3x = x
