The area of the old rug, we know, is 8 * 4 = 32 feet squared.
If we double the dimensions, we get that 8 becomes 8 * 2 = 16 and 4 becomes 4 * 2 = 8.
Then, the new area is 16 * 8 = 128 feet squared.
128/32 = 4, or choice (J).
Answer:
- 40 popcorns and 90 pretzels sold.
============
Let the number of popcorns is x and pretzels is y.
Set up equations:
- x + y = 130
- 2.5x + 2y = 280
Solve by elimination, multiply the first equation by 2 and subtract from the second equation:
- 2.5x + 2y - 2x - 2y = 280 - 2*130
- 0.5x = 280 - 260
- 0.5x = 20
- x = 20/0.5
- x = 40
Find y:
- 40 + y = 130
- y = 130 - 40
- y = 90
Answer:
$5.46
Step-by-step explanation:
You would take $98.28 and divide it by 18 and the answer would be $5.46
Please give me brainliest :)
To solve, isolate the x. Cross multiply
3/13(13)(5) = x/5(5)(13)
3(5) = (13)x
Simplify
13x = 15
Isolate the x. Divide by 13.
13x/13 = 15/13
x = 15/13
x = 1.2
1.2 is your answer
hope this helps
