Answer:
60°
Step-by-step explanation:
angle A +angle B +angle C = 180
30° +B+90°= 180
120°+B=180°
B=180°-120°
B=60°
Answer:
6000 pounds
Step-by-step explanation:
calculator
If we say A = ream of paper and B = cost of ink than we can set-up an expression to calculate when A is equal to a number what the number of B will be.
Maximim of 270$ so anything we buy must be equal to this.
Ream of paper cost 6$ each so 6A represents the number of reams bought since we said A is number of reams of paper.
Ink Cartridges are 18$ each so 18B would represent this based on B = to cost of ink.
Now setting up our equation
6A + 18B = 270
When A = 1
B = 14.67 Ink Cartridges
When A = 1 Ream ofpaper
Answer:
Step-by-step explanation:
The side length of a square is represented by the expression 2x + 5.
The area of a square is given as:
where a = length of side of the square
The area of the square is therefore:
The perimeter of a square is given as:
The perimeter of the square is therefore:
The difference between the area of the square and the perimeter of the square is:
The expression that represents the difference between the area and the perimeter of the square is:
