Maybe try this <span>2x+y=16
3x-y=4
------------
Add the two equations to solve for "x":
5x = 20
x = 4
--------
Substitute to solve for "y":
2*4 + y = 16
y = 8
----------
Solution: (4,8)</span>
Slope is rise over run, or the change in y over the change in x. So, you go up vertically then directly horizontal and whatever the change is is the slope.
For example, the first one is -1/3. It's slope is going down to the right, so it's negative . It goes down 1 (y value) and over to the right 3 (x value). Since it goes down and to the right it is a slope of -1/3.
Area of square pizza = 15 *15 = 225 in²
area of circular pizza = πr² = 3.14 * 8² = 200.96 in²
how much more = 225 - 200.96 = 24.04 in²
Answer:
x=−2
Step-by-step explanation:
He would need 11.1 gallons of gas if he was/would drive 296 miles.
12 divided by 320 = .0375
.0375 x 296 = 11.1 Gallons of Gas needed to drive the distance.
