How many solutions exist for the equation: 8(4-2x)=4(3-5x)+4x

A) Two solutions
B) One solution
C) No solution
D) Many solutions

Answers

Answer 1

Answer:

C

Step-by-step explanation:

We have the equation:

[tex]8(4-2x)=4(3-5x)+4x[/tex]

Let's expand both sides. Distribute on the left:

[tex]32-16x=4(3-5x)+4x[/tex]

Distribute on the right:

[tex]32-16x=12-20x+4x[/tex]

Combine like terms on the right:

[tex]32-16x=12-16x[/tex]

Add 16x to both sides:

[tex]32\neq12[/tex]

This is not true.

So, our equation has no solutions.

This would mean that our two linear equations are parallel to each other.

Our answer is C

Answer 2

Wednesday morning, the temperature was −12 ∘F. By the afternoon, the temperature was 23 ∘F. Write and then evaluate a subtraction expression to determine the number of degrees of change in temperature between the morning and the afternoon.

Answers

23-12=11 11 degrees should be the answer

The change in temperature between the morning and the afternoon would be 35° F.

What is the Subtraction operation?

Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.

We have been given that Wednesday morning, the temperature was −12° F. By the afternoon, the temperature was 23° F.

We have to determine the change in temperature between the morning and the afternoon

As per the given question,

Here, final temperature = 23° F and initial temperature = −12° F

The change in temperature = final temperature -  initial temperature

The change in temperature =  23° F - ( -12° F )

Apply the subtraction operation,

The change in temperature =  23° F + 12° F

The change in temperature =  35° F

Hence, the change in temperature between the morning and the afternoon would be 35° F.

At Gas Station Z, the cost of 15 gallons of gasoline is $51.30, and the cost of 8 gallons of gasoline is $27.36. What is the cost, in dollars per gallon, of the gasoline at the gas station with the greater cost?

Answers

At gas station Z, it is $3.42 per gallon. At gas station Y, it is $3.37 per gallon. Gas station Y is a better deal and the cost per gallon of the gasoline at the gas station with the greater cost (gas station Z), is $3.42

Gas station Y is cheaper than gas station Z

What is Unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

At Gas Station Z, the cost of 15 gallons of gasoline is $51.30

So, cost of 1 gallon at station Z

=51.30/15

= 3.42

and, At Gas Station Y, the cost of 5 gallons of gasoline is $16.85

So, cost of 1 gallon at station Y

=16.85/5

= 3.37

Hence, Gas station Y is cheaper than gas station Z

Step 3:

∠ABC = 65°    Alt. Int. ∠'s   ( Alternate Interior ∠'s)

Answer:

B: 65°

Hope This Helps :)

[tex]\tt Step-by-step~explanation:[/tex]

To find the measure of ∠ABC, we need to know that the sum of the interior angles of a triangle is 180º.

[tex]\tt Step~1:[/tex]

Triangle CED has two given angles: 65º and 50º. We can add them together and subtract that from 180 to get the third measure.

[tex]\tt 65+50=115\\180-115=65[/tex]

[tex]\tt Step~2:[/tex]

Since lines AB and ED are parallel, that means m∠ACB is also 65º since the vertical angle is also 65º. Then, we can add 65 and 50 together and subtract that from 180 to get our answer.

Mike hiked to a lake in 5.5 hours at an average rate of 2 1/5 miles per hour. Pedro hiked the same distance at a rate of 2 3/5 miles per hour. How long did it take for Pedro to reach the lake? Round to the hundredths place.

Answers

We first need to find the distance.

The information about Mike will provide the distance we need to answer the question about Pedro.

We will use D = rt

Mike:

(6.5)((17/5) = D

22.1 miles = D

Pedro:

D = rt

22.1 = (19/5)t

We need to find t.

22.1 ÷ 3.8 = t

5.8157894737 = t

We now round off as instructed.

5.82 = t

It took Pedro 5.82 hours to reach the lake.
