How many three-fourths are in 2? 2 complete sets of three-fourths can be made and 2 of the 3 pieces need to make \frac34 are left over, so we have another \frac23 of a three-fourths. and we can see that there are 2 wholes with 4 fourths in each whole, so there are 2\times 4 fourths in 2.
Answer:
60 oz of water to add
45 oz of 35% salt solution should be used
Step-by-step explanation:
Let x = amt no. ounces in the first solution
and 105 - x = amt no. of ounces in the second solution
Ist solution contains 0% salt
2nd solution contains .35(105 - x) salt
.15(105= amt of salt in mix
So.
amt of salt in 1st solution + amt of salt in 2nd solution = amt of salt in the mix
0 + .35(105 - x) = .15(105)
Let's get rid of the fractions by multipying thru the equation by 100
35(105 - x) = 15(105)
3675 - 35x = 1575
-35x = -2100
x = 60 oz of water to add
105 - 60 = 45 oz of 35% salt solution should be used
The correct answer for this question is A.
Find the price for each apple by dividing the price over the number of apples. At Quixk Market, each apple costs 1.05/3 or $.35 per apple.
At Stop and Save, you can buy one apple for 2.45/5 or $.49.
The Quick Market is a better buy because It has $.15 less for each apple.
Hope this helps.
Answer:
<h2>y = -4x</h2>
Step-by-step explanation:
Solve 20x + 5y = for y
20x + 5y = 0
subtract 20x both sides
5y = -20x
simplify:
y = <u>-20x</u>
5
finally
y = -4x
