Answer:
The expression would be 8w
Answer:
To solve for an equation with two variables, substitute a zero(0) into the other variable and find one variable.
Step-by-step explanation:
To solve for an equation with two variables, substitute a zero(0) into the other variable and find one variable.
Simple Example:
3x+3y=12
Substitute 0 as y,
3x+0=12
3x=12
12/3=4
x=4
Now substitute 4 into the main equation,
3(4)+3y=12
12+3y=12
-12 -12
3y=0
0/3=0
y=0
So the answer is
3(4)+3(0)=12
12=12
Answer:
we have
(x,y). rotation through 90° anti-
clockwise about the origin(-y,x)
point (−8, 4) when rotated through 90° anti-
clockwise about the origin(-4,-8)
<u>Option.i. (−4, −8)</u>
The formula to solve:

(10 being the percent)


Therefore it had a 180% decrease.
Answer:
<h2><u><em>
$1.75</em></u></h2>
Step-by-step explanation:
if a wire of length 2 meters costs $10. find the cost of a wire of length 35cm $1.75
2m = 200 cm
200 : 10 = 35 : x
x = 10 * 35 : 200
x = 1.75
