Answer:
The answer would be 280
Step-by-step explanation:
If there are about 4 weeks in each month and she eats out every week for 45 dollars.
45x4=180
and if she goes to the movies each week at 25 dollars do the same thing.
25x4=100
when you add the two sums together
180+100=280
finally you subtract 280 from the original number,
500-280=220
so delores would have 220 dollar left over for other activities.

Answer:
170
Step-by-step explanation:
First, find the area of the rectangles. It's length is 10, and the width is 5. Multiply them to get an area of 50. Since there are 3 congruent rectangles, multiply that by 3. Then find the area of the triangle. It's height is 4, and the base is 5. Multiply and divide by 2, giving you 10. Since there is a congruent triangle add 10 again, as well as the area of the 3 rectangles.
50+50+50+10+10 = 170
8,000 is 10 times as much as 800
2/5 ÷ x = 4/5
multiply both sides by x to get it out of the denominator.
2/5 = 4/5x
now divide each side by 4/5 to get x by itself.
2/5 ÷ 4/5 = x
divide fractions by multiplying the reciprocal of the divisor.
2/5x × 5/4 = x
10/20 = x
1/2 = x
So 2/5 divided by 1/2 =4/5
