You start with the equation 70(.20)
Where .20 is the % as a decimal.
The answer is 14
Answer:
300
Step-by-step explanation:
Is means equals and of means multiply
18 = 6% * N
Change to decimal form
18= .06N
Divide by .06 on both sides
18/.06 = .06N/.06
300 = N
The number is 300
Answer:
x = -1 and y = -1
Step-by-step explanation:
Solve 3x+3y=−6;−x+y=0
Steps:
I will solve your system by substitution.
−x+y=0;3x+3y=−6
Step: Solve−x+y=0for y:
−x+y+x=0+x(Add x to both sides)
y=x
Step: Substitutexforyin3x+3y=−6:
3x+3y=−6
3x+3x=−6
6x=−6(Simplify both sides of the equation)
6x
6
=
−6
6
(Divide both sides by 6)
x=−1
Step: Substitute−1forxiny=x:
y=x
y=−1
Answer:
x=−1 and y=−1
Answer:
Uh, this isnt solvable, you sure u got the right problem???
Step-by-step explanation:
Answer:
Step-by-step explanation:
The equation has one solution.
6(x+2)=5(x+7)
6x+12=5x+35
6x+12-5x=35
6x-5x=35-12
x=23
Therefore, the equation has ONE solution.
