Answer:
32
Step-by-step explanation:
Alright, so think of the "what number" as x in this case. (Or any number/symbol you choose.)
So our simple equation looks something like this:
[tex]24= x *\frac{3}{4}[/tex]
So, to find out what the "what number" would be we'd flip the fraction around/find the reciprocal and multiply 24 by it. That gives us "x" or the number we're missing.
So: [tex]24 * \frac{4}{3} = x[/tex]
Doing the simple math we get:
[tex]24 * \frac{4}{3} = 32[/tex].
32 is your answer.
Hope this helps and have a nice day! Sorry I'm not great at explaining it!

The value of Rita's house increased by 5%.
Her house then had a value of £210 000.
Work out the value of Rita's house before the increase.
Answer: £200,000
Step-by-step explanation:
From the question, we are informed that the value of Rita's house increased by 5% and that her house then had a value of £210 000.
The value of Rita's house before the increase will be calculated as:
= 210,000 ÷ (100% + 5%
= 210000 ÷ 105%
= 210000 ÷ 105/100
= 210000 × 100/105
= £200,000

solve the simultaneous Equation
3/x- 4/y= 1/3
Answer:
a simultaneous equation is a set of equations. you need at least another equation.
Answer:
Step-by-step explanation:
Let's solve for x.
3x−4y= 1/ 3
Step 1: Add 4y to both sides.
3x−4y+4y= 1/ 3 +4y
3x=4y+ 1/ 3
Step 2: Divide both sides by 3.
3x/ 3 = 4y+ 1/ 3
3 x= 4/ 3 y+ 1/ 9
Answer:
x= 4/ 3 y+ 1/ 9
Let's solve for y.
3x−4y= 1/ 3
Step 1: Add -3x to both sides.
3x−4y+−3x= 1/ 3 +−3x
−4y=−3x+ 1/ 3
Step 2: Divide both sides by -4.
−4y/ −4 = −3x+ 1/ 3
−4 y= 3/ 4 x+ −1/ 12
Answer:
y= 3/ 4 x+ −1/ 12

What is 10 times something equal 24
Answer:
2.4
Step-by-step explanation:
An easy way to find this is via division.
24 ÷ 10 = 2.4 | therefore,
2.4 × 10 = 24
Answer:
2.4
Step-by-step explanation:
"something" = x
10x = 24
divide both sides by 10
10x/10 = 24/10
x = 2.4

Select all expressions that are equivalent to 6x + 1 - (3x - 1).
Select one or more:
a. 6x - 3x + 1 - 1
b. 6x + 1 + -3x - -1
c. 6x + -3x + 1 + 1
d. 3x + 2
e. 6x + 1 - 3x - 1
Answer: B, C, D
Step-by-step explanation:
6x + 1 - (3x -1)
=> 6x + 1 - 3x + 1
=> 3x + 2
So Answers: B, C, D
The expression that should be equivalent to 6x + 1 - (3x - 1) is option B, C, D.
Calculation of the expression:Since the equation is 6x + 1 - (3x - 1)
So,
6x + 1 - (3x -1)
6x + 1 - 3x - (-1)
6x + 1 -3x + 1
And, 3x + 2
Therefore, we can conclude that The expression that should be equivalent to 6x + 1 - (3x - 1) is option B, C, D.

Use the Pythagorean theorem to solve each problem. Show Calculations.
Answer:
1) 25 miles
2) 20 m
Step-by-step explanation:
Number 1 is going to be
[tex]a^{2} + b^{2} = c^{2}[/tex] because it's a right triangle
So
[tex]24^{2}[/tex] + [tex]7^{2}[/tex] = [tex]c^{2}[/tex]
625 = [tex]c^{2}[/tex]
c = 25 mile
Number 2 uses the same process, but changing to using C instead of A
a^2 = c^2 - b^2
a^2 = 625 - 225
a = \sqrt(400)
a = 20m
