given: x+y=10 if x=-21, what is y?
Answer: y = 31
Step-by-step explanation: all you need to do is plug in the x
since x = -21 we can put: -21 + y = 10
now we add 21 to both sides giving us: y = 31
Answer:
(-21,22)
Step-by-step explanation:
x+y=10
x=-21
subtitue the x value
-21+y=2
solve for y
y=22
Then write your answer by ordered pair

To evaluate g(r - 9), substitute p = r - 9 into g(p) , that is
g(r - 9) = (r - 9)² + 8 ← expand factor using aFOIL
= r² - 18r + 81 + 8
= r² - 18r +89

A family of 2 adults and 3 children went on holiday to Miami.
The family visited a theme park.
They paid a total of 322 dollars to go in.
The exchange rate was £1 = 1.84 dollars.
Change 322 dollars to pounds (£).
Answer:
£175
Step-by-step explanation:
Given the exchange rate was £1 = 1.84 dollars.
We are to change 322 dollars to pounds (£).
£1 = 1.84 dollars.
x = 322 dollars
Cross multiply
1.84 * x = 322
1.84x = 322
x = 322/1.84
x = 175
Hence 322 dollars in pounds will be £175

Heather invests $3572 in a retirement account with a fixed annual rate of 5% compounded 4 times per year what will the account balance be after 16 years
Answer:
$7910.3
Step-by-step explanation:
Given data
P=$3572
n=4
T=16 years
R= 5%
The compound interest is expressed as
A= P(1+r/n)^nt
Substitute
A=3572(1+0.05/4)^16*4
A=3572(1+0.0125)^64
A=3572(1.0125)^64
A=3572*2.21453241061
A=$7910.3

Belvedere goes to the store and buys a soccer ball for $50. The store
is running a discount of 10%. What is the price of the soccer ball after
the discount?
Answer:
$45 after the discount
Step-by-step explanation:
Set up a proportion.
[tex]\frac{x}{50} = \frac{10}{100}[/tex] $50 is the total amount and make the 10% a decimal
x(100) = 50(10)
100 = 500
100 ÷ 500
x = 5 <-- We have to subtract this amount from the total
$50 - $5 = $45 <-- total after the discount
Hope this helps!!

1/3(c) when c = 64. What’s the answer using PEMDAS
Answer:
21.3 repeated
Step-by-step explanation:
Let's look at our equation
1/3c
We also have the number that c stands for, which is 64, so what we must do is replace c with 64.
1/3(64)
Now we have the equation 1 over 3 multiplied by 64, so multiply as is.
64 * 1 = 64
Therefore,
64/3
Now divide :
21.3 repeated

Solve for X. 12y-4x=10
Answer:
x=-5/2+3y
Step-by-step explanation:
If this answer helped you then please consider making this brainliest and thank this response :)
Answer:
x = -2.5 + 3y
Step-by-step explanation:
Simplifying
12y + -4x = 10
Reorder the terms:
-4x + 12y = 10
Solving
-4x + 12y = 10
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-12y' to each side of the equation.
-4x + 12y + -12y = 10 + -12y
Combine like terms: 12y + -12y = 0
-4x + 0 = 10 + -12y
-4x = 10 + -12y
Divide each side by '-4'.
x = -2.5 + 3y
Simplifying
x = -2.5 + 3y
