At the movies, you order 3 boxes of popcorn and a bottle of water. The cost of the bottle of water Is $1.75. Your total is $9.25
Phoenix [80]
If popcorn is p and water is w the equation can be written as

3p + w = 9.25

because there was 3 boxes of popcorn and one water (hence the coefficients) and the total is 9.25

then plug in 1.75 for w the price of water:

3p+ 1.75 = 9.25

you can move stuff around algebraically now (subtract 1.75 on both sides and divide by three on both aides) to get the cost of one box of popcorn (p).

The answer is 2.50

The radius of a circle is 2 inches. what is the circles diameter
andrey2020 [161]
The diameter is a line that stretches across the middle of a circle from end to end.  The radius is one half of this line, stretching from the center of the circle to a point on the side of the circle.  This means that the diameter is 2 times the length of the radius.  2 times 2 is 4, meaning that the diameter is 4 inches.

Suppose you borrow 13,000 for four years at 7% toward the purchase of a car.
dangina [55]
Amount borrowed, P = 13000
Interest, i = 0.07/12 per month
number of periods (months),  n = 4*12 = 48

Monthly payment, 
A=\frac{P(i*(1+i)^n)}{(1+i)^n-1}
=\frac{13000(.07/12*(1+.07/12)^{48}}{(1+.07/12)^{48}-1}
=311.30   (to the nearest cent)

I WILL NAME BRAINLIEST FOR WHOEVER CAN WRITE THE ANSWER! I WILL NOT GIVE IT ANYONE WHO JUST POINTS! What is the area of the figu
PtichkaEL [24]

Answer:

48.5cm^{2}

Step-by-step explanation:

This shape is actually just a rectangle with a missing triangle. We can first find the area of the rectangle with 7*8=56 and subtract the triangle.

Area of missing triangle = \frac{1}{2} *b*h (b is the base and h is the height)

Base = 8-3=5

Height = 7-4=3

Area of missing triangle = \frac{1}{2} *5*3=7.5

Area of the figure: 56-7.5=48.5

--------------------------------------------------------------------------

Alternatively, you can find the area of each individual shape and add them all up.

Area of the rectangle: 8*4=32

Area of square: (7-4)*3=9

Area of triangle: \frac{1}{2} *(8-3)*(7-4)=\frac{1}{2} *5*3=7.5

Total Area: 32+9+7.5=48.5
