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.

Answer:
therefore the second bouquet will have more flowers , as it will have 25 daisies
Step-by-step explanation:
3 roses for every 5 carnations
5 daisies for every 4 carnations
we can solve this using cross multiplication
3 : 5
x : 20
5x = 60
x = 60/5
<em>x = 12</em>
meaning that for a bouquet that has 20 carnations there will be 12 roses
5 : 4
x : 20
4x = 100
<em>x = 25</em>
meaning that for a bouquet that has 20 carnations there will be 25 daisies.
<u>therefore the second bouquet will have more flowers , as it will have 25 daisies</u>
Important: indicate exponentiation with " ^ "
Thus, x = ( y - 4 )2 + 27 becomes <span>x = ( y - 4 )^2 + 27
This can be re-written as x = y^2 - 8y + 16 + 27, or x = ay^2 - 8y + 43. This is the equation of the parabola in standard form x = ay^2 + by + c.</span>
I hope this helps you
x= -2
f (-2)= -2-7
f (-2)= -9
So basically, think of a ratio as a fraction for these problems. You see the 2 numbers and you put the first one as the numerator and the second as your denominator. For example:
5 to 10
We would change this into:

Because the problem says to simplify, we can divide both sides by 5 and simplify it into:

If the problem says 5:10 instead of "5 to 10" it's the same problem just with different wording. If the numbers are labeled, the you can write the labels next to the number it corresponds with.
