Answer:
The value of x any y are "-5.29 and 0.79" and "3.79 and -2.29"
Step-by-step explanation:
Given values:
After solve equation (a) we get
After solve equation (b) we get
put the value of x in to equation (x)
The value of y is = -5.29 and 0.79, put the value of y in x1 equation so, we get: 3.79 and -2.29

Answer:
17% off $35
Step-by-step explanation:
The reason I say 17% off $35 is better price is because you get $5.95 off the original price.
So how did you do it they wonder, well in order to find out how much we are going to be taking off of a number as a percentage we have to turn 17% and 12% into a decimal by multiplying 17% and 12% by 100.
17% * 100 = 0.17
12% * 100 = 0.12
Now we multiply 0.12 by $32 and 0.17 by $35 in order to find out how much money you are saving:
0.12 * $32 = $3.84
0.17 * $35 = $5.95
So since $5.59 is bigger than $3.84 you have your answer 17% off $35 is a better price.
A cell with 2cm sides has a surface area of 6 × a2 or <span> a</span>2<span> + a</span>2<span> + a</span>2<span> + a</span>2<span> + a</span>2<span> + a</span><span>2

These are vertical angles, so they are equal in measurements.
First, simplify [2(x + 10)]
Distribute 2 to all terms within the parenthesis
2(x + 10) = 2x + 20
Next, place both expressions equal to each other
2x + 20 = 3x - 30
Solve for x. Isolate the variable. Subtract 3x and 20 from both sides
2x (-3x) + 20 (-20) = 3x (-3x) - 30 (-20)
2x - 3x = -30 - 20
Simplify
-x = -50
Isolate the x. Divide -1 from both sides
-x/-1 = -50/-1
x = 50
50 is your answer for x
hope this helps
