Answer:
The value of x is 3.
Step-by-step explanation:
Matthew earned 7500 of 15000, which is exactly half the total amount, meaning that the fraction corresponding to his earnings is 1/2.
Rate of 5:2:x, with number 5 corresponding to Matthew, mean that his fraction of the earnings, in function of x is given by:
[tex]\frac{5}{5 + 2 + x} = \frac{5}{7 + x}[/tex]
Both fractions are equal, so:
[tex]\frac{5}{7 + x} = \frac{1}{2}[/tex]
Applying cross multiplication:
[tex]7 + x = 10[/tex]
[tex]x = 10 - 7[/tex]
[tex]x = 3[/tex]
The value of x is 3.

22. Find the value of x.
Answer:
62° & 54°
Step-by-step explanation:
Answer 21 :-
We know that the measure of a straight line is 180° .
x + 118° = 180° x = 180° - 118° x = 62°Answer 22:-
2x + 1 + 71 = 180 2x = 180 - 72 2x = 108 x = 54°Answer:
62° & 54°
Step-by-step explanation:
Answer 21 :-
We know that the measure of a straight line is 180° .
x + 118° = 180°
=> x = 180° - 118°
=> x = 62°
Answer 22:-
2x + 1 + 71 = 180
=> 2x = 180 - 72
=> 2x = 108
=> x = 54°

Which of the following rational functions is graphed below?
Answer:
[tex]A = \frac{1}{(x-1)(x+1)}[/tex]
Step-by-step explanation:
Looking at the dashed lines in the graphic, these functions have two discontinuities, at x = -1 and at x = 1.
A discontinuity in a rational function is a point in which the denominator of the function is 0.
For these options, the denomiator is 0 at both x = -1 and x = 1 for only option A, so the answer is:
[tex]A = \frac{1}{(x-1)(x+1)}[/tex]

The diameter of a semicircle is 4 kilometers what is the semicircle's radius
Answer:
To find the radius, just take half of the diameter. The answer is 2.
Step-by-step explanation:
Semicircle Area and Perimeter
Area (A)
6.2832in²
A = πr²/2 = 2 * π [in²] ≈ 6.2832 [in²]
Perimeter (L)
10.2832 in
L = πr + d = 2 * π + 4 [inch] ≈ 10.2832 [inch]

190% of what number is 76
Plz hurry I really want to get this done
Answer:
190 is 76% of 250
Step-by-step explanation:
We have, 76% × x = 190
Multiplying both sides by 100 and dividing both sides by 76,
we have x = 190 × 100/76
x = 250
If you are using a calculator, simply enter 190×100÷76, which will give you the answer.

You were born, your mother deposited 2000 in an account that pays 5% simple interest. How much would the balance be in your account when you enter college 18 years after?
A. 18000
B. 1800
C. 3800
D. 20000
Answer:
C
Step-by-step explanation:
the formula for simple interest is given as A=P(1+rt), where A is the final balance, P is the initial principal balance (the amount of money that you start out with), r is the annual interest rate, and t is the time
we know that the mom deposited 2000 into an account when the person was born. This is our initial principal balance (the amount of money started out with)
substitute that value into the formula to get:
A=2000(1+rt)
we also know the rate, which is 5% and the time, which is 18
5%=0.05 (we need it as a decimal)
so substituting the values into the equation:
A=2000(1+0.05*18)
A=2000(1+0.9)
A=2000(1.9)
A=3,800
therefore the answer is C
Hope this helps!

Hey yall!! How do I do this ???
Answer:
Step-by-step explanation:
just pick three values (numbers) into the function and calculate the other unknown
You can pick an X or you can pick a Y, then solve for Y or X respectively.
Record these x,y pairs in the table
once you have at least two points you can graph the function
y = mx + b y-intercept form of the line function
m = slope b is the value of y when x = 0
y = -5x/2 -5 let x = 0 solve for y
y = -5(0)/2 -5
y = 0 - 5
y = -5
y = -5x/2 -5 solve for x
y + 5 = -5x/2 - 5 + 5 add 5 to both sides
y + 5 = - 5x/2
(y +5 )(-2/5) = (-5x/2) (-2/5)
(y +5 )(-2/5) = x let y = 0
(0) +5)(-2/5) = x
5(-2/5) = x
-2 = x
I'll let you have the third variable to pick and solve for the dependent variable. The dependent variable is just wha it sounds like, it is dependent on which ever independent (the value you randomly pick) variable.
Pick either x or y then solve for y or x
y = -5x/2 -5 solve for y
x = (-2/5) (y +5) solve for x
