Answer:

C = 8

Hope this helps!

Step-by-step explanation:

C - 12 = -4

C - 12 + 12 = -4 + 12 ( Add both sides by 12 )

C = 8 ( Simplify )

Answer:

C = 8

Step-by-step explanation:

Rearrange the equation to make C the subject.

C - 12 = -4

Add 12 to both sides.

C - 12 + 12 = -4 + 12

C = -4 + 12

C = 8

Check it:

C = 8

So substitute the new found value into the original equation:

C - 12 = -4

8 - 12 = -4

-4 = -4

All good.

Solve for y 2x-5y=10

scZoUnD [109]

Answer:

y = 2/5x - 2

Step-by-step explanation:

Step 1: Write equation

2x - 5y = 10

Step 2: Solve for y

Subtract 2x on both sides: -5y = 10 - 2x
Divide both sides by -5: y = -2 + 2/5x
Rewrite: y = 2/5x - 2

Someone please help me !!! i need it by 7:30!! ammm!!!

Answer:

LON and MLN are both equal to 126 degrees,

since the angles with the value '4x + 7' and '7x - 35' degrees are equal to each other, you can rewrite it like this:

4x+7=7x-35

now, take the 7x away from both sides:

-3x+7=-35

then, subtract 7 from both sides:

-3x=-42

now, divide both sides by -3:

x=14

now that we know the value of x (14), we can plug it into the expressions.

4(14)+7=63

7(14)=63

add them together to find the angle MLN

and since the opposite angle (LON) is equal to MLN, they both = 126 degrees

hope this helped :)

What is the answer to 21=(x+3)2

IceJOKER [234]

First, distribute 2 to the (x+3) to get:
21 = 2x+6
subtract 6 from both sides to get:
15 = 2x
Finally, we divide both sides by 2 to simplify x to:
x = 7.5 (OR) x = $7 \frac{1}{2}$
(Just so you know, if you pick a brainliest answer, both you and the person who got the brainliest answer get some points.
