−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

In which equation would you multiply both sides by 4.5 to get the variable alone?
A.6.1p = 4.5
B.p ÷ 6.1 = 4.5
C.p ÷ 4.5 = 6.1
D.4.5p = 6.1
By applying the multiplication property, the equation you would multiply both sides by 4.5 to get the variable p alone is: C. p ÷ 4.5 = 6.1
Recall:
When applying the multiplication property of equality to find a variable, both sides of the equation will be multiplied by the same term/value.Therefore, for the equation p ÷ 4.5 = 6.1, which is:
p/4.5 = 6.1
To get the variable p alone, multiply both sides by 4.5
Thus:p/4.5 × 4.5 = 6.1 × 4.5
p = 27.45
Therefore, by applying the multiplication property, the equation you would multiply both sides by 4.5 to get the variable p alone is: C. p ÷ 4.5 = 6.1

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.

Please answer I really need help I will give BRAINIEST for whoever answers first, second, third, fourth, and fifth.
Answer:
the answer is C because according to the graph, the y-intercept is -6 and the slope is 3.
slope is rise over run, so find a point thats directly on a corner of the grid (i chose the y-intercept) and then count to see how many lines are between that point and the next one that's directly on the lines. (it's (1, -3)) making the slope 3/1 or 3
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.

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.

X-Y=3
2x+2y=50
Answer:
abcdefg
Step-by-step explanation:
Answer:
x = 14
y = 11
Step-by-step explanation:
x - y = 3
2x + 2y = 50
multiplty x - y = 3 by two so we can get an equal value
2x - 2y = 6
2x + 2y = 50
-2y and 2y can be cancled out. That means we don't need to change any signs and we can add everything exept 2y and -2y becuase they will be cancled out.
4x = 56
Divide each side by 4 to leave x alone.
x = 14
Now that we know the x value, take one of the equations in the question and plug it in. I am going to use the equation x - y = 3 to make it easier.
14 - y = 3
-y = 3 - 14
-y = -11
y = 11
Now we know that y = 11.

e
It will take them 1 hour to drive 50 miles
Answer: To convert the time it takes to travel a certain number of hours, you need to know your ... how many hours it takes to drive a certain number of miles, and you can also ... If you're traveling in a line from point A to point B, determining your average ... often use the words speed and velocity interchangeably, they aren't the same!
Step-by-step explanation:
Answer:
B. it will take them 8 hours to drive 400 miles
D. It will take them 18 hours to drive 900 miles
E. It will take them 1 hour to drive 50 miles
Step-by-step explanation:
First, you solve for how fast there going an hour so in three hours they go 150 so we can divide 150 by 3 and we get 50. That means they go 50 miles in an hour. Then we can multiply 50 by the hours and see if we get the same number on miles.

Mathematics includes the study of such topics as quantity, structure, space, and change. It has no generally accepted definition. Mathematicians seek and use patterns to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof.
Step-by-step explanation:
Mathematics is the study of numbers, shapes and patterns. The word comes from the Greek word "μάθημα" (máthema), meaning "science, knowledge, or learning", and is sometimes shortened to maths (in England, Australia, Ireland, and New Zealand) or math (in the United States and Canada). ... Numbers: how things can be counted.
Therefore, Mathematics is the abstract study of topics such as quantity (numbers), structure, space, and change!

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
