Answer:
x=1
Step-by-step explanation:
3x-15=17-x
3x-x=17-15
2x=2
x=1
Answer:
x=8
Step-by-step explanation:
3x-15=17-x move variable to the left and change its sign
3x+x-15=17 collect like terms
4x=17 + 15 (3x=x=4x)
4x= 32 divide both sides by 4
x=8 (dividing 4x by 4 cancels the 4,s out and leaves x)

The length of a rectangle is 7 cm more than its width. If the diagonal of
the rectangle is 35 cm, find the dimensions of the rectangle.
What is the width an length ?
Answer:
Length = 12, width = 5
Step-by-step explanation:
The diagonal is the hypotenuse of a rectangular triangle.
Equation: d^2 = l^2 + w^2
35^2 = (x + 7)^2 + x^2
169 = (x + 7)(x + 7) + x^2
169 = x^2 + 7x + 7x + 49 + x^2
169 = 2x^2 + 14x + 49
subtract 169 from both sides
0 = 2x^2 + 14x - 120
divide by 2
0 = x^2 + 7x - 60
factor, to find the numbers just think of what number multiplied by what number would equal -60 and have the same numbers added together equals 7. 12 times 5 is 60 but it has to be -60, and 12 - 5 equals 7 so the numbers would be 12 and -5
0 = (x + 12)(x -5)
x = -12, and x = 5, but u can only use positive solutions so length equals 12 and width is 5

x=3m/2-m
make m the subject of the formula
help me plss
Answer:
2X/(3+X)
Step-by-step explanation:
X = 3m/2-m
Cross multiply both sides
X × (2-m)= 3m
2X-Xm= 3m
2X= 3m+Xm
2X= m(3+X)
Divide both sides by the coefficient of m which is (3+X)
m= 2X/(3+X)
Changing the subject of a formula involves rearranging the formula
m as the subject of the formula is: [tex]\mathbf{m = \frac{2x}{3 + x}}[/tex]
The equation is given as:
[tex]\mathbf{x = \frac{3m}{2-m}}[/tex]
Cross multiply
[tex]\mathbf{x(2-m) = 3m}[/tex]
Open brackets
[tex]\mathbf{2x-mx = 3m}[/tex]
Collect like terms
[tex]\mathbf{2x= 3m +mx}[/tex]
Factor out m
[tex]\mathbf{2x= m(3 +x)}[/tex]
Divide both sides by 3 + x
[tex]\mathbf{\frac{2x}{3 + x}= m}[/tex]
Rewrite the above equation as:
[tex]\mathbf{m = \frac{2x}{3 + x}}[/tex]
Hence, m as the subject of the formula is:
[tex]\mathbf{m = \frac{2x}{3 + x}}[/tex]

How do you do this question?
Answer:
a. 42%

a. According to the curve, the bottom 80% of families has about 58% of the income, so the top 20% has about 42%.
b. The bottom 60% of families have about 32% of the income, and the bottom 40% of families have about 16% of the income. So the third quintile has about 32% − 16% = 16%.
A worker in an assembly line takes 5 hours to produce 24 parts. At that rate, how many parts can she produce in 25 hours?
Answer: 120
Step-by-step explanation: To get how many parts is produced every hours you divide 24 and 5 which gets you 4.8. And to get how many is produced in 25 hours you do 25 x 4.8.
The number of parts that can be produced in 25 hours is 120 parts.
First find out the number of parts that can be produced in an hour:
= Number of parts/ Number of hours
= 24 / 5
= 4.8 parts per hour
Now that you have the parts produced per hour, you can find out how much can be produced in 25 hours:
= Parts produced per hour x number of hours
= 4.8 x 25
= 120 parts

20 pts, try to find short story and novel pages, A novel has 13 times as many pages as a short story. The combined number of pages in the books is 448 pages. How many pages are in each book?
Short Story:
Novel:
Answer:
short story has 32 pgs
novel has 416 pgs
Step-by-step explanation:
a novel (N) has 13 times as many pages as a short story (x) so, N = 13X
total pages is the equation N + x = 448
plug the equation for N into this
13x + x = 448, combine like terms
14x = 448, divide both sides by 14
x = 32. so now we know that the short story has 32 pages. subtract that from 448. and the novel has 416 pages.
There are 32 pages in the short story and 416 pages in the novel.
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
Let x be the number of pages in the short story.
We know that the novel has 13 times as many pages as the short story, so the number of pages in the novel is 13x.
The combined number of pages in the books is the sum of the number of pages in the short story and the number of pages in the novel, which is x + 13x = 14x = 448 pages.
So the number of pages in the short story is x = 32 pages.
And the number of pages in the novel is 13x = 13 × 32 = 416 pages.
