Answer:
a. We spent all together 40.2+24.5+37.8=$102.50.
b. We saved 19.8+10.5+7.2=$37.50
c.
Step-by-step explanation:
To find the amount we spend, we multiply the original price by the decimal conversion of each fraction. Then we add the amounts together.
- Sneakers cost $60 and you bought them at 2/3=0.6666....
60(0.67)=$40.20 and saved $19.80
- Sweater costs $35 and you bought it at 7/10=0.7
35(0.7)=$24.50 and saved $10.50
- A jacket costs $45 and you bought it at 5/6=0.8333...
45(0.84)=$37.80 and saved $7.20
We spent all together 40.2+24.5+37.8=$102.50.
We saved 19.8+10.5+7.2=$37.50
We could of spent paying regular price 60+35+45=$140. To find the fraction we place the total we actually paid over the total regular price.
C. 8.6 units because if you use the Pythagorean thereom and square the bottom side and the left side and add them, you get the square root of 74 which is 8.6023.... and you round it too 8.6
Answer:
2x-8+3x+2=4x+10+3x-6
We move all terms to the left:
2x-8+3x+2-(4x+10+3x-6)=0
We add all the numbers together, and all the variables
2x+3x-(7x+4)-8+2=0
We add all the numbers together, and all the variables
5x-(7x+4)-6=0
We get rid of parentheses
5x-7x-4-6=0
We add all the numbers together, and all the variables
-2x-10=0
We move all terms containing x to the left, all other terms to the right
-2x=10
x=10/-2
x=-5
Step-by-step explanation:
We can't tell without knowing its shape. Also, if it's a rectangle, we need to know one of its dimensions.
