Area = base * height = 35 square inches
When we make the dimensions 2.5 by 3.5 then,area = 2.5 * 3.5 = 8.75 square inches
35 / 8.75 = 4So, when we reduce the width AND the height by 2, the area decreases by 4.Why? Because when we are reducing 2 dimensions:area = width/ 2 * length / 2 = area / 4
Answer:
Line PU has points R and S between points P and U, lines QR and ST are parallel, line QR intersects line PU at point R, line ST. intersects line PU at point S, the measure of angle PRQ is 135 degrees, and the measure of angle UST is 15 ( x plus 2 ) degrees. X = −1 x = 7 x = 9 x = 13
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
7x + 21 = 12x - 4
25 = 5x
5 = x

Answer:
200 adults
Step-by-step explanation:
We can set-up a system of equations to find the number of adults. We know children and adults attended. We will let c be the number of children and a be the number of adults. Since 200 people attended, then c+a=200.
We also know they made $800 and adult tickets cost $4 and child tickets cost $2. We can write 2c+4a=800.
We will solve by substituting one equation into the other. We start by solving the first equation for c. c+a=200 becomes c=200-a.
Now we substitute c=200-a into 2c+4a=800. Simplify and isolate the variable a.
- 2(200-a)+4a=800
- 400-2a+4a=800
- 400+2a=800
- 400-400+2a=800-400
- 2a=400
- a=200
This means that 200 adults attended and 0 children attended.
