3(x - 2) = 18
Answers
Answer:
Standard form:
3x − 24 = 0
Factorization:
3(x − 8) = 0
Solutions:
x = 24

= 8
Step-by-step explanation:
Hope this helps? :))
To solve for x, we have to isolate the variable.
First, we distribute 3 to (x - 2) because when there are parentheses with terms inside it next to another term, then we have to multiply them together.
Next, we add six on the left side of the equation to cancel out - 6. We also add 6 to the right, because we have to do whatever we do on both sides of the equation.
Finally, we divide both sides by 3 to isolate x and get our answer.

area=πr²
1) we calculate the radius of this circle.
Data:
area=9π m²
area=πr²
9π m²=πr²
r²=9π m² / π
r²=9 m²
r=√(9 m²)=3 m
2) we calculate the circumference:
circumference=2πr=2π(3 m)=6π m
Answer: the circumference is 6π m
parallel to the line 4x – 3y = 16?
Answers
Add 4x to each side, and get -3y=16+4x. Rearrange it to get it in the right order (y=mx+b).
This is -3y=4x+16. So the number in front of 'x' is 'm', which is the slope. You never actually see 'm', it is represented by a number. So four is the slope.
Answer:
the given eqaution y=mx+b represents a straight line with slope m and the y intercept b.
So now let us see how to graph the equation y=5x+(-6):
Putting x=0, we get y=-6 which implies one coordinate is (0,-6)
Now putting x=1, we get y=-1 which implies the coordinate is (1,-1)
Putting x=2, we get y=4. So the coordinate is (2,4)

b=brother age
s= 2 times b
s=2b
if difference beteeen ages is 15
sarah is older so
s-b=15
we now have
s=2b
s-b=15
since s=2b
sub 2b for s in othe equaiton
2b-b=15
b=15
