This is just y = mx + b with two equations so

y = 0.15x + 39.98;
y = 0.13x + 53.98

Since y is equal to y and 0.15x + 39.98 = y, and 0.13x + 53.98 = y we can substitute y.

0.15x + 39.98 = 0.13x + 53.98

You need to use the subtraction property on both sides so
(0.15x +39.98)-39.98 = (0.13x + 53.98)-39.98

.15x + 0 = .13x + (53.98-39.98)
.15x = .13x + 14

Then subtract .13x from both sides

.15x - .13x = .13x - .13x + 14
.02x = 14

Simplify
.01x = 7

we want one x so multiply both sides by 100
(.01x)100 = (7)100
x = 700

Evaluate the following expression using the values given:
LiRa [457]
Hey there! :) 

2x - 3y - z ; When x = -2, y = 3, & z = -2

Since we're given the values of x, y, & z, we can very simply plug everything in! 

2(-2) - 3(3) - (-2)

Simplify.

(-4) + (-9) + 2

Get rid of parenthesis.

-4 - 9 + 2

Remember to do PEMDAS! 

Parenthesis
Exponents
Multuply
Divide
Add
Subtract

So, since adding comes before subtracting, let's add! :) 

-4 - 9 + 2

-4 - 7

Simplify.

-11

So, our answer is [A] : -11

~Hope I helped!~

6289002 rounded to the nearest million
daser333 [38]
It's easier to see the numbers if you use commas.
6,289,002
The 6 is in the millions place. When rounding, if the following number is 5 or higher, you would round up. If the following number is 4 or less, you would round down. The number following the 6 is a 2, so you would round down. The nearest million would be 6,000,000.
