Answer:
y=5x
Step-by-step explanation:
A product means multiplication, and you need to multiply x by 5 in order to make the product have a factor of 5.
75 + 10 = 85
85 - 10 = 75
85 - 75 = 10
There is nothing to solve for.
Answer:
C =131.88 cm
Step-by-step explanation:
We can find the circumference of a circle by using
C = pi * diameter
C = 3.14 * 42
C =131.88 cm
Let's solve your equation step-by-step.
−2(x+3)=(−10)(−2)
Step 1: Simplify both sides of the equation.
−2(x+3)=(−10)(−2)
(−2)(x)+(−2)(3)=(−10)(−2)(Distribute)
−2x+−6=20
−2x−6=20
Step 2: Add 6 to both sides.
−2x−6+6=20+6
−2x=26
Step 3: Divide both sides by -2.
−2x
−2
=
26

x=−13
Answer:
m = 0
Step-by-step explanation:
1/2(-1.4m+0.4)=m+0.2
We move all terms to the left:
1/2(-1.4m+0.4)-(m+0.2)=0
Domain of the equation: 2(-1.4m+0.4)!=0
m∈R
We get rid of parentheses
1/2(-1.4m+0.4)-m-0.2=0
We multiply all the terms by the denominator
-m*2(-1.4m+0.4)-(0.2)*2(-1.4m+0.4)+1=0
Wy multiply elements
-2m^2(--(0.2)*2(-1.4m+0.4)+1=0
We use the square of the difference formula
-2m^2(+(0.2)*2(-1.4m+0.4)+1=0
