28.150=26.5 is the amount you can spend on water. so 26.5/1.29= 20.54 so you can buy 20 bottles of water

Eli wants to combine 0.5 gallon of a 10% acid solution with some 35% acid solution to make a 15% acid solution. Which equation c

Alex17521 [72]

Answer:

Equation is $0.5 \text{ gal }\times(0.1)+ x\text{ gal }\times (0.35)=(0.5 + x)\times (0.15)$

0.125 gallons of the 35% acid solution Eli should add.

Step-by-step explanation:

Given : Eli wants to combine 0.5 gallon of a 10% acid solution with some 35% acid solution to make a 15% acid solution.

To find : Equation can you use to determine how many gallons of the 35% acid solution Eli should add?

Solution :

Let x be the gallons of the 35% acid solution.

According to question,

For 0.5 gallon of a 10% acid solution = $0.5\times 0.1$

For x gallon of a 35% acid solution = $x\times 0.35$

For (0.5+x) gallon of a 15% acid solution = $0.5+x\times 0.15$

The equation form is

$0.5 \text{ gal }\times(0.1)+ x \text{ gal }\times(0.35)= (0.5+x)\times (0.15)$

Solving the above equation,

$0.05+0.35x = 0.075 + 0.15x$

$0.2x = 0.025$

$x =\frac{0.025}{0.2}$

$x=0.125$

Therefore, 0.125 gallons of the 35% acid solution Eli should add.

The equation is $0.5 \text{ gal }\times(0.1) + x \text{ gal }\times(0.35) =(0.5 + x)\times (0.15)$

Point D(2, 4) is rotated 180° about the origin, what is the coordinate of D

nadezda [96]

Answer: D(-2, -4)

All you have to do in this situation is make your answer negative, because they will both be going to the negative side. This also would be the same thing for if they are already negative you turn them positive.

Julio says, "If you subtract 12 from my number and multiply the difference by -5, the result is -40." What is Julio's numbe

ZanzabumX [31]

Answer:

Julio's number is 212

Step-by-step explanation:

(x - 12) ÷ -5 = -40

x - 12 = -40 times -5

x - 12 = 200

x = 200 + 12

x = 212

Check:

(x - 12) ÷ -5 = -40

((212 - 12)) ÷ -5 = -40

200 ÷ -5 = -40

-40 = -40
