Answer:
Step-by-step explanation:
Remember to use the order of operations stands for (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) from left to right.
First, do parenthesis.
6(3-5)+7(4+2)
(3-5)=-2
6(-2)+7(4+2)
(4+2)=6
6(-2)+7*6
Multiply.
6(-2)=-12
-12+7*6
7*6=42
-12+42
Add or subtract.
-12+42=30
30, which is our answer.
Answer:
C = 2 π r
Step-by-step explanation:
Your answer is 2 pi/π r.
The formula of a circumference is always 2 pi r.
18 x 3.14 x 2 = 113.04
in this case radius is 18
pi is 3.14
2 is just always there when finding out circumference.
let "one number" = x, and "another" = y
x = 4y + 4
(x + y) - 4 = 28
Plug in 4y + 4 for x
4y + 4 + y - 4 = 28
Simplify. Combine like terms
5y = 28
Isolate the y. Divide 5 from both sides
y = 28/5
y = 5.6
Plug in 28/5 for y.
x = 4y + 4
x = 4(28/5) + 4
Simplify
x = 22.4 + 4
x = 26.4
x = 26.4, y = 5.6
hope this helps
Answer:
Multiply both sides, then divide by 2.
Step-by-step explanation:
A triangle is either half of a square, or half of a rectangle. The two numbers given are the dimensions to the quadrilateral. Halving it gives you the area of a triangle.
First of all move all the Xs to the left side, and the numbers to the left.
So
x/2-x = -13
Which means
X/2-x/1 = -13
Which means x/2-2x/2 = -13
So u combine to two fractions
-x/2 = -13
-x = -13 * 2
Which means x = 26 (u flip the negativity)
