[tex]x + 5 / 3[/tex] -[tex]X - 3 / 2[/tex]
Answer:
[tex]x + \frac{5}{3}-x - \frac{3}{2} = \frac{1}{6}[/tex]
Step-by-step explanation:
Given
[tex]x + \frac{5}{3}-x - \frac{3}{2}[/tex]
Required
Solve
[tex]x + \frac{5}{3}-x - \frac{3}{2}[/tex]
Collect like terms
[tex]x + \frac{5}{3}-x - \frac{3}{2} = x -x+ \frac{5}{3} - \frac{3}{2}[/tex]
[tex]x + \frac{5}{3}-x - \frac{3}{2} = \frac{5}{3} - \frac{3}{2}[/tex]
Take LCM
[tex]x + \frac{5}{3}-x - \frac{3}{2} = \frac{10 -9}{6}[/tex]
[tex]x + \frac{5}{3}-x - \frac{3}{2} = \frac{1}{6}[/tex]

One side of a tabletop is 12x – 5 units long. Another side of the tabletop is 7x + 4 units long. If the tabletop is a square, what is the value of x?
Answer:
Step-by-step explanation:
All the sides of a square are equal, so:
12x - 5 = 7x + 4
12x - 7x = 4 + 5
5x = 9
x = 9/5

Suppose a student visited 81 websites while conducting research. If 9 of the websites were "us.gov" websites, what percentage of the websites visited were NOT "us.gov" websites? Round your answer to the nearest whole percent.
Answer:
9/81 or 1/9 = .1111111111R
Step-by-step explanation:
It is that because that is the decimal and 9 goes into 9 once and 9 goes into 81 nine times
three odd consecutive integers are such that 3 times the smallest is 9 more than twice the largest .find the three numbers
Answer: 17, 19, 21
Step-by-step explanation:
Three consecutive odd numbers: x, x+2, x+4 (since odd numbers occur every other number)
Just to show you that the numbers are x, x+2, and x+4, just say x is 13 then x+2 is 15 and x+4 is 17 (3 consecutive odd numbers)
Now the second equation:
3x = 2(x+4) + 9
three times smallest number (which is x) is equal to 2 times the largest number (x+4) plus 9
Now solve
3x = 2(x+4) +9
3x = 2x + 8 + 9
3x = 2x + 17
x = 17
x+2 = 19
x+3 = 21

Bliss is collecting money for a fundraiser. She starts with a $2 bronze star donation from her parents, then receives 3 equal silver star donations from her neighbors. If she ends with $18, how much money does she receive from a silver star donor?
Answer: $5.33
Step-by-step explanation:
Bliss was able to collect $18 in total.
Out of this total, she received a $2.00 bronze star donation and the rest were 3 Silver star donations.
This means that the 3 equal silver star donations added up to:
= 18 - 2
= $16.00
This means that each silver star donation was:
= Amount in total / Number of silver stars
= 16 / 3
= $5.33

Colin invests £1100 into his bank account.
He receives 5% per year simple interest.
How much will Colin have after 3 years?
Give your answer to the nearest penny where appropriate.
£
Answer:
Colin will have $1,265 after three years.
Step-by-step explanation:
First, we find the amount of interest Colin will have by using the following formula,
simple interest = principal * interest rate * time
now that we know the formula, we substitute the numbers in.
simple interest = $1,100 * 5% * 3
since the interest rate is obviously a percentage, we have to convert it into a decimal.
simple interest = $1,100 * 0.05 * 3
now that it is a decimal, we can solve this expression.
simple interest = $1,100 * 0.05 * 3
simple interest = $55 * 3 (here, we did $1,100 * 0.05 first so that it doesn't get confusing with all the numbers, it will be easier with two final numbers)
simple interest = $165
Colin has $165 simple interest but over here asks how much she will have AFTER 3 years. think about it, can you have $165 after having $1,100 in your bank AFTER 3 years? no, so we need to add the interest by the principal by using the following formula,
total amount = principal + simple interest
now, we substitute the numbers in.
total amount = principal + simple interest
total amount = $1,100 + $165
total amount = $1,265
Therefore, Colin will have $1,265 after 3 years.
find the surface area of a cylinder with a base diameter of 4 yd and a height of 4 yd . write your answer in terms of π , and be sure to include the correct unit. How do I solve this?
Answer:
Surface area of cylinder = 24π
Step-by-step explanation:
Given:
Base diameter = 4 yd
So Radius = 4 / 2 = 2 yd
Height = 4 yd
Find:
Surface area of cylinder
Computation:
Surface area of cylinder = 2πr(h+r)
Surface area of cylinder = 2π(2)(4+2)
Surface area of cylinder = 2π(2)(6)
Surface area of cylinder = 24π

for what value of q is in the question -13(q+4)=7q+16
Answer:
q=-3 2/5
Step-by-step explanation:
First multiply -13 with (q+4)
-13q-52=7q+16
Now you have to change the order before = the numbers with q and after = the numbers without anything
-13q-7q=52+16
Remember that when you change positions the symbol too
Then solve it
-20q=68
Now u have to divide as i do
q=68/-20
you can simplify it
q=3 8/-20
Now divide by the greater divisor in this case is 4
q=3 2/-5
And organize it
q=-3 2/5
Never forget to do q=(answer)
Hopefully it helps.

Answer:
D. D₂ (∆XYZ)
Step-by-step explanation:
Dₙ = (x,y) → ((n)x, (n)y)
_________________
X = (-1, 2).
Y = (2, -1).
Z = (-2, -1).
_________
Dₙ ∆XYZ:
X(-1, 2) → X'(-2, 4)
Y(2, -1) → Y'(4, -2)
Z(-2, -1) → Z'(-4, -2)
______________
-2 / -1 = 2, 4 / 2 = 2.
4 / 2 = 2, -2 / -1 = 2.
-4 / -2 = 2, -2 / -1 = 2.
_______________
D₂ = (x,y) → ((2)x, (2)y).
X(-1, 2) → ((2)(-1), (2)(2)) = X'(-2, 4)
Y(2, -1) → ((2)(2), (2)(-1)) = Y'(4, -2)
Z(-2, -1) → ((2)(-2), (2)(-1)) = Z'(-4, -2)
