−15x−40=23−8x
What does x =
Answer:
x = -9
Step-by-step explanation:
-15x - 40 = 23 - 8x
Add 8x to both sides
-15x + 8x - 40 = 23
-7x - 40 = 23
Add 40 to both sides
- 7x = 23 + 40
-7x = 63
Divide both sides by (-7)
x = 63/-7
x = -9
Answer:
x = -9
Step-by-step explanation:
-15x - 40 = 23 - 8x
add 8x to both sides to bring -8x to the left side
-15x + 8x - 40 = 23
add 40 to both sides to bring -40 to the right side
-15x + 8x = 23 + 40
add the common terms
-7x = 63
for x to be alone divide -7 to both sides
x = -9

The Hendersons went on a driving vacation. They decided to travel 1/3 of the distance on the first day. Owing to bad weather, they had to stop for the night having gone only 1/4 of the distance to the one-third point.
What fraction of the total distance did they travel the first day? Show your work and reduce to lowest terms.

Nathan used 2(5/6) loaves of bread to make sandwiches for a lunch. He made equal numbers of 4 different types of sandwiches.
What fraction of a loaf of bread did Nathan use for each type of sandwich?
Answer:
A)
[tex]\displaystyle \frac{1}{12}[/tex]
B)
[tex]\displaystyle \frac{3}{5}[/tex]
C)
[tex]\displaystyle \frac{17}{24}[/tex]
Step-by-step explanation:
Part A)
The Hendersons were traveling 1/3 of the distance on the first day.
However, they had to stop, having only traveled 1/4 of the 1/3 distance.
So, we can multiply the two fractions together.
Therefore, the fraction of the total distance they traveled is given by:
[tex]\displaystyle \frac{1}{4}\times\frac{1}{3}=\frac{1}{12}[/tex]
The Hendersons traveled 1/12 of the total distance.
Part B)
We are assuming the bottle of milk was full at the beginning.
So, at the beginning, there were 1/1 bottle of milk left.
Howie fed a piglet 1/5 of the bottle. So, there is now:
[tex]\displaystyle 1-\frac{1}{5}[/tex]
Of the bottle left.
Making common denominators and subtracting yields:
[tex]\displaystyle =\frac{5}{5}-\frac{1}{5}=\frac{4}{5}[/tex]
So, after feeding the piglet, 4/5 of the bottle of milk was still there.
3/4 of the remainder was fed to a calf.
So, the amount that was fed to the calf is 3/4 times 4/5. Therefore:
[tex]\displaystyle \frac{3}{4}\times\frac{4}{5}[/tex]
Multiply:
[tex]\displaystyle =\frac{12}{20}=\frac{3}{5}[/tex]
So, the calf drank 3/5 of the bottle of milk.
Part C)
Nathan used 2 (5/6) loaves of bread to make 4 sandwiches.
First, convert 2 (5/6) to an improper fraction. So:
[tex]\displaystyle 2\frac{5}{6}=\frac{12+5}{6}=\frac{17}{6}[/tex]
Nathan made 4 sandwiches using this. So, we will divide this by 4. Note that this is the same as multiplying by 1/4. Therefore:
[tex]\displaystyle \frac{17}{6}\times\frac{1}{4}=\frac{17}{24}[/tex]
So, Nathan used 17/24 loaves of bread per sandwich.

Ben bought 2 shirts for $16 each, 3 pairs of socks for $2.50 a pair, and a pair of jeans for $37.75. If the sales tax rate is 6.5%, how much did he pay for his items, including tax?
$127.46
$92.81
$82.27
$59.91
Answer:92.81
Step-by-step explanation:
Answer:
$82.27
Step-by-step explanation:
First, figure out how much it would be without tax.
(2*16=32) + (3*2.50=7.50) + 37.75 = 77.25
Then, multiply this number by your tax rate.
77.25*6.5 = 5.02
Lastly, add your original total with this tax amount for your answer.
77.25+5.02= 82.27
a car drives at a rate of 65 mi/hr. what is the speed of the car in ft/s? note: 1 mi = 5280 ft
Answer:. 95.33 ft/sec

9. The two figures below have a scale factor of 3 : 2. What is the value of x?
The value of x can be found by setting up a proportion based on the given scale factor of 3:2 is 16/3 units.
The breadth of the first parallelogram is 8 and the breadth of the second parallelogram is x.
Setting up the proportion, gives:
8/3 = x/2.
To solve for x, cross-multiply:
[tex]8 \times 2 = 3 \times x.[/tex]
Simplifying the equation, gives:
16 = 3x.
Next, divide both sides of the equation by 3 to isolate x:
x = 16/3.
Therefore, the value of x is 16/3.

Kayla is given a monthly allowance. She uses 40% of this allowance to purchase a designer bag, and then donates $15 to a charity. If she ends up with $155, which of the equations below can be used to determine what her monthly allowance was?
a. 0.40 X -15 = 155
b. 40 X + 15 = 155
c. 0.60 X - 15 = 155
d. 60 X -15 = 155
Answer:
A. 0.40x - 15=155
Step-by-step explanation:
40% can be written as 0.40
x = total money earned
-15 from that total
The expression which can be used to calculate her monthly allowance is 0.6X - 15 = 155
Let :
monthly allowance = X Designer bag purchase = 40% of X = 0.4X Donation to charity = $15Total amount left = $155Percentage left after bag purchase :
1 - 0.4X = 0.6X0.6X - charity = amount left
Therefore, the required expression is 0.6X - 15 = 155
