Answer:
C. Subtract 19
Step-by-step explanation:
Answer:
Subtract 19 from each side
Step-by-step explanation:
19 + 8x = 91
Subtract 19 from each side
19-19 + 8x = 91 -19
8x = 72
Then divide each side by 8
8x/8 = 72/8
x = 9
Simplify the given equation.
5x + 2(x - 3) = -2(x - 1)
a. 7x - 3 = -2x - 1
b. 7x - 6 = -2x + 2
c. 7x - 6 = -2x - 2
Solve
5x + 2x -6 = -2(x - 1)
7x - 6 = -2(x-1)
Distribute
7x - 6 = -2(x - 1)
7x - 6 = -2x + 2
Add 6 to each side
7x - 6 + 6 = -2x + 2 + 6
Simplify
7x = -2x + 8
x = 8/9
So your answer is B. I believe
5x + 2(x - 3) = -2(x - 1)
its 8/9

Find the solution of the system equation.
Choose the expressions below that are equivalent to the following algebraic expression.
2(5x-3) + 4x
Select ALL that apply.
7x-5+ 4x
-6 + 14x
10x - 6+ 4x
11x-5
-5 + 11x
14x-5
Please help
Answer:
10x -6 +4x & -6 + 14x are equivalent to the algebraic Expression : 2(5x -3) + 4x
Step-by-step explanation:
First, you should Simplify the expression.
2(5x -3) + 4x = 10x -6 +4x <-- Here we distributed. We see this expression is an option, so you would choose that.
We Contiue:
10x -6 + 4x = -6 + 14x <-- here we added the like terms, 10x and 4 x
Next:
-6x + 14 = -2.3. <-- here we got our answer, but our choices are only expressions, so this is just an extra step.
Answer
-6 + 14x
10x - 6+ 4x

If you are riding your bike west to your friend’s house, and you ride the 1.25 miles in 5 minutes, what is your velocity, in miles per hour?
Answer:
v= 15miles/hr (west)
Step-by-step explanation:
This is physics, so I'll use the most common formula. v=d/t. Convert 5 mins to an hour. 5min/60min = 1/12hr.
v= 1.25 miles / 1/12hr
v= 15miles/hr (west). Don't forget the right arrow on the v.
Answer:
15miles/hr (west)

What is the value of n 10/2 = 4/n
1. 20
2. 35
3. 25
4. 30
Answer:
20
Step-by-step explanation:
We can simplify 10/2 = 5
5 = n/4
Multiply each side by 4
5*4 = n/4*4
20 =n
Answer: n = 20
Explanation: To solve for n in this proportion,
we simply use the means-extremes property.
Since 10/2 = n/4, we know that the product of the extremes,
(10)(4), equals the product of the means, (2)(n).
So we know that (10)(4) or 40 equals (2)(n) or 2n.
Dividing both sides by 2, 20 = n.

Answer:
13.83
Step-by-step explanation:
12*106/92=13.82
Answer:
13.83Step-by-step explanation:
If y varies inversely it has equation:
y = k/xWe have
y = 106, x = 12Then, finding the value of k:
106 = k/12k = 106*12= 1272For x = 92
y = 1272/92 = 13.83 roundedThe last option is correct

Asia woke up late. It is 5:45 a.M. And is trying to decide if she has enough time to catch the bus. If it takes her 5 minutes to throw on an outfit, a minimum of twice as long to do her hair and make-up, and eight minutes longer than that to walk to the bus stop. Her bus driver regularly arrives at 6:15 am. Will she make it?
Answer:
Step-by-step explanation:
If Asia woke up by 5:45am and her bus regularly arrives at 6:15 am, the the total amount of time Asia needs to finish up to meet the bus is time within this interval of time i.e 30mintes.
Total time taken to dress up:
Time taken to throw an outfit = 5minutes
Time taken to do her hair and make up = 2(5) = 10 minutes
Time to walk to bus stop = 5+8 = 13minutes(8 minutes longer)
Total time she took to finish up and get to the bus = 5+10+13 = 28 minutes
Since the time used by Asia is less than the 30 minutes expected of her hence she will meet the bus
Answer:
She would be 3 minutes late.
Step-by-step explanation:
The time difference between 5:45 am and 6:15 am = 30 minutes
If it takes her 5 minutes to throw on an outfit = 5 minutes
A minimum of twice as long to do her hair and make-up = ≤ 5 × 2
≤ 10 minutes
Eight minutes longer than that to walk to the bus stop.
= 8 minutes longer than how long it takes her to do her hair and makeup
= 10 + 8
= 18 minutes
Total number of times it takes her to make it to the busstop
=( 5 + 10 + 18)minutes
= 33 minutes
Therefore, she will not make it because she would be 3 minutes late.

granola bite contains 27 calories. Most of the calories come from grams of carbohydrates. The rest come from other ingredients. One gram of carbohydrate contains 4 calories. The equation LaTeX: 4c+5=27 represents the relationship between these quantities.
Answer:
5 1/2
Step-by-step explanation:
The calories contained are from grams of carbohydrates and other ingredients
One gram of carbohydrate contains 4 calories
The equation 4c + 5 = 27 represents the relationship between these quantities.
1. 5 from the equation represent calories from other ingredients
2. Neither 8 nor 3 is the solution to the equation
4c + 5 = 27
When 8 is the solution
4(8)+5=27
32+5=27
37=27
When 3 is the solution
4(3)+5=27
12+5=27
17=27
Neither 8 nor 3 is the solution to the equation because 8 gives a higher calories in the granola bite and 3 gives a lower calories in the granola bite.
3. Solution to the equation
4c + 5 = 27
4c= 27-5
4c = 22
Divide both sides by 4
c=22/4
=5 2/4
=5 1/2
The solution to the equation is 5 1/2
Totsakan and Lea each improved their yards by planting hostas and geraniums. They bought their supplies from the same store. Totsakan spent $178 on 14 hostas and 12 geraniums. Lea spent $71 on 7 hostas and 4 geraniums. What is the cost of one hosta and the cost of one geranium?
Answer:
The cost of one hosts is $5 and the coat of one geranium is $9
Step-by-step explanation:
Let the cost of one hosta be x
Let the cost of one geranium be y
If Totsakan spent $178 on 14 hostas and 12 geraniums, then the expression to represent this statement will be;
14x+12y = 178
7x+6y = 89 .... 1
Also if Lea spent $71 on 7 hostas and 4 geraniums, the the expression that represent the statement is;
7x+4y = 71..... 2
Subtract equation 1 from 2:
(7x-7x)+(6y-4y) =89-71
0+2y = 18
2y = 18
y = 18/2
y = 9
Substitute y = 9 into equation 1:
7x+6(9) = 89
7x +54 = 89
7x = 89-54
7x = 35
x = 35/7
x = 5
Therefore the cost of one hosts is $5 and the coat of one geranium is $9

A trapezoid has a base of 4.5 inches, a height of 6 inches, and an area of 21 square inches. The equation below can be used to determine b2, the length in inches of the second base of the trapezoid.
12(4.5+b2)(6)=21
What is the length, in inches, of the second base of the trapezoid?
Answer:
The second base of the trapezoid b2 is 2.5 inches
Step-by-step explanation:
Here, we want to calculate the second base of the trapezoid.
Mathematically, the area of a trapezoid can be given as;
A = 1/2(a + b) h
where a and b represents the parallel bases and h is the height of the trapezoid
so this, we have from the question
1/2(4.5 + b2) * 6 = 21
3(4.5 + b2) = 21
divide both sides by 3
4.5 + b2 = 7
b2 = 7-4.5
b2 = 2.5 inches

The ingredients are doubled in the large Totally Turkey Sandwich. On Wednesday, three times as many customers ordered the regular sandwich as the large sandwich. If 27 customers ordered the regular sandwich, how many total slices of turkey were used to make the sandwiches that day?
Answer:
45 slices of turkey used
Step-by-step explanation:
In order to figure out this problem we first need to calculate the total amount of sandwiches that were ordered. Since 27 regular sandwiches were ordered and we know that three times as many customers ordered the regular sandwich as the large sandwich. Then we simply divide 27 by 3 to find out how many large sandwiches were ordered.
27 / 3 = 9 large sandwiches.
Now, assuming that each regular sandwich only takes one slice of turkey, we can multiply 9 by 2 since each large sandwich takes double the slices and add that to 27 to calculate the total number of slices used in all of the sandwiches for that day.
(9*2) + 27 = s
18 + 27 = s
45 = s
There were a total of 45 slices of turkey used.
