Eli wants to combine 0.5 gallons of a 10% acid solution with a 35% solution to make a 15% acetic acid solution. He needs to determine how many gallons of 35% solution are needed.
Eli decides to let v represent the volume of the 35% solution and makes a table to help solve the problem.
Help Eli by completing the table.
Answers
Answer:
Here you go :)
Step-by-step explanation:
0.0125 gallons of 35% solution is needed.
Given that,
Eli wants to combine 0.5 gallons of a 10% acid solution with a 35% solution to make a 15% acetic acid solution.
Eli decides to let v represent the volume of the 35% solution.
We have to find,
How many gallons of 35% solution is needed?
According to the question,
Eli decides to let v represent the volume of the 35% solution.
And 0.5 gallons of 10% acid solution,
the volume of the 15% acid solution is (v +0.5).
Therefore,
0.5 gallons of a 10% acid solution with a 35% solution to make a 15% acetic acid solution.
[tex]\rm = 0.5 \times \dfrac{10}{100} + v \times \dfrac{35}{100} = (v+0.5) \times \dfrac{15}{100}\\\\= 0.5 \times 0.01 + v \times 0.35 = (v+0.5) \times 0.15\\\\= 0.05 + 0.35v = 0.15v + 0.075\\\\= 0.35v - 0.15v = 0.075 -0.05\\\\= 0.20v = 0.025\\\\v = \dfrac{0.025}{0.20}\\\\v = 0.0125[/tex]
Hence, 0.0125 gallons of 35% solution is needed.

Determine if (3, 7) is a Solution or not Solution to the linear system.
y = 2x + 1
y = -4x + 7
Answers
Answer:
y = 2x + 1 --> linear
y = -4x + 7 --> non-linear
Not a solution for linear system.
Step-by-step explanation:
for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:
7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.
for (b), we have to substitute our values again. You get:
7 = -4x3 + 7, which is
7 = -12+7, which is not true. So, (b) is not linear.
This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.

Theo bought 2 hot dogs and two drinks for $4.00. At the same concession stand, Vicky bought 3 hot dogs and a drink for $4.50. Write a system of equations and find what is the price of a hot dog concession stand?
Answers
Answer:
The hot dog are $2.63
Step-by-step explanation:
Hot Dogs = H
Drinks = D
2H + 2D = 4
Divide both sides by 2
H + D = 2
Subtract D from either side
H = 2 -D
3H + D = 4.50
Plug in 2 - D for H
3(2- D ) + D = 4.50
6 - 3D + D = 4.50
6 - 4D = 4.50
Add 6 to either side
-4D = 10.50
Divide either side by -4
D = -2 . 625

pearl will put wire around a rectangular lot with a width of 20m and a length that is two times its width.how many mters of wire will she need?
Answers
Let's see what to do buddy...
_________________________________
STEP (1)
First we need to find the length.
(( length is two times the width ))
Length = 20 × 2 = 40 m
_________________________________
STEP (2)
Pearl will put wire around a rectangular.
Around of rectangular = Perimeter of it
So we must to find the perimeter of the rectangular.
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: p = 2(length + width) \\ \\ p = 2(20 + 40) \\ \\ \: \: \: \: p = 2 \times 60 = 120[/tex]
So Pearl needs 120 meters of wire.

Which expression shows 7+21 written as a product of two factors?
(A)3(1+7)
(B)3(3+7)
(C)7(3+3)
(D)7(1+3)
Answers
Expressing or writing 7+21 as a product of two factors requires the application of Distributive Property
The expression that shows 7+21 written as a product of two factors is
7(1 + 3).
To solve the above question, we apply the Distributive property.This is expressed as:a (b + c) = ab + ac
Where
a is the common factor
We are given the expression:
7 + 21
Splitting this into two factors using the distributive property
7 + 21
The common factor for 7 and 21 is 7
Hence, by factorising we have:
7 + 21 = 7(1 + 3)
Therefore, the expression that shows 7+21 written as a product of two factors is :
7(1 + 3)
The correct option is D

Un número desconocido es multiplicado por 11 y a este resultado se le resta 24. El resultado de esta operación es 86. Escribe en lenguaje algebraico la expresión anterior y contesta: ¿Cuánto vale el número desconocido?
Answers
Answer: The number is 10.
Step-by-step explanation:
Let x be the required number.
Given: 11 is multiplied to the number then 24 is subtracted from that and the result is 86.
The mathematical statement for the given situation,
11x -24 = 86
To solve the equation, Add 24 on both sides , we get
11x - 24 +24 = 86+24
⇒ 11x = 110
Divide both sides by 11, we get
x = 10
hence, the number is 10.
