Isaiah was given a gift card for a coffee shop. Each morning, Isaiah uses the card to
buy one cup of coffee. The original amount of money on the gift card was $10 and
each
cup
of coffee costs $2. Write an equation for A, in terms of x, representing the
amount money remaining on the card after buying x cups of coffee.
Answer:
$10 - $2x = A
Step-by-step explanation:
The equation for A, in terms of x, represents the amount of money remaining on the card after buying x cups of coffee is $10 - $2x = A.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Given that Isaiah was given a gift card for a coffee shop. Each morning, Isaiah uses the card to buy one cup of coffee. The original amount of money on the gift card was $10 and each cup of coffee costs $2.
The equation will be written as below,
$10 - $2x = A.
A is the amount of money remaining on the card
x is cups of coffee.
Therefore, the equation for A, in terms of x, represents the amount of money remaining on the card after buying x cups of coffee is $10 - $2x = A.

what does i2x + 3(x - 5) = 20 equal
Answer:
x=7
Step-by-step explanation:
2x+3(x-5)=20
2x+3x-15=20
5x-15=20
5x=35
x=7
Answer:
x = 5
Step-by-step explanation:
2x + 3(x - 5) = 20
simplify
5x - 5 = 20
get the variable and the number on different sides
5x - 5 + 5 = 5x
20 + 5 = 25
5x = 25
now divide each side by 5
5x / 5 = x
25 / 5 = 5
x = 5

Step-by-step explanation:
Answer:
D
Step-by-step explanation:
The third one down.
32.1y+3.1+2.4y-8.2=34.5y-5.1
Combine like terms
34.5y + 3.1 - 8.2 = 34.5y - 5.1
34.5y - 5.1 = 34.5y - 5.1 y can be anything
===========================
Remove the brackets from D
11y + 17 = 5y - 10 + 6y
11y + 17 = 11y - 10
This gives 17 = - 10 which of course is nonsense.
D has no solution.

What are the first 4 terms use the explicit rule:
f(n)= 3n-1
(show your work)
Answer:
25811Step-by-step explanation:
We are given the rule [ f(n) = 3n - 1 ] and n represents the term.
First term:
f(n) = 3n - 1
f(1) = 3(1) - 1
f(1) = 3 - 1
f(-1) = 2
Second term:
f(n) = 3n - 1
f(2) = 3(2) - 1
f(2) = 6 - 1
f(2) = 5
Third term:
f(n) = 3n - 1
f(3) = 3(3) - 1
f(3) = 9 - 1
f(3) = 8
Fourth term:
f(n) = 3n - 1
f(4) = 3(4) - 1
f(4) = 12 - 1
f(4) = 11
As you can see, the common difference is 3.
Best of Luck!

h(x)=2x+5 k(x)=x+3 find (h(k(x)))
Answer:
h(k(x)) = 2x + 11
Step-by-step explanation:
Step 1: Define
h(x) = 2x + 5
k(x) = x + 3
h(k(x))
Step 2: Substitute and Evaluate
k(x) = x + 3 = x
h(k(x)) = 2(x + 3) + 5
h(k(x)) = 2x + 6 + 5
h(k(x)) = 2x + 11
One year Terry had the lowest ERA (earned-run average, mean number of runs yielded per nine innings pitched) of any male pitcher at his school, with an ERA of 2.85 . Also, Karla had the lowest ERA of any female pitcher at the school with an ERA of 2.95 . For the males, the mean ERA was 4.893 and the standard deviation was 0.949 . For the females, the mean ERA was 4.348 and the standard deviation was 0.997 . Find their respective z-scores. Which player had the better year relative to their peers, Terry or Karla ? (Note: In general, the lower the ERA, the better the pitcher.)
Answer:
Their respective z-scores are:
Thomas : -2.15279
Karla : -1.40221
Which player had the better year relative to their peers, Terry or Karla ?
Terry had a better year because he had a lower Era and he was a better pitcher.
Step-by-step explanation:
The formula for calculating a z-score is is z = (x-μ)/σ,
where x is the raw score,
μ is the population mean
σ is the population standard deviation.
any male pitcher at his school,
For Thomas:
z = (x-μ)/σ
x = 2.85 μ = 4.893 σ = 0.949.
z = 2.85 - 4.893/0.949
z = -2.15279
For Karla
z = (x-μ)/σ
x = 2.95 μ = 4.348 σ = 0.997.
z = (2.95 - 4.348) /0
z = -1.40221
Their respective z-scores are:
Thomas : -2.15279
Karla : -1.40221
Which player had the better year relative to their peers, Terry or Karla ? (Note: In general, the lower the ERA, the better the pitcher.)
Terry had a better year because he had a lower Era and he was a better pitcher.
the average rain fall in cuba in the summer is 5.3 inches per month. if cuba gets 6.3 inches in june and 7.1 in july how much rain do they need in august to exceed their average
Answer:
They need more than 2.5 inches.
Step-by-step explanation:
average = 5.3
June: 6.3
July: 7.1
August: x
The average of the amounts for June, July, and August is
(6.3 + 7.1 + x)/3
To exceed the average, the average must be greater than 5.3.
(6.3 + 7.1 + x)/3 > 5.3
Multiply both sides by 3.
6.3 + 7.1 + x > 15.9
x + 13.4 > 15.9
Subtract 13.4 from both sides.
x > 2.5
Answer: They need more than 2.5 inches.

Answer:
y=3x+2
Step-by-step explanation:
y=mx+b
We have our m, which is slope, but we need our y intercept, b.
Substitute your slope, x, and y into the formula and solve for b.

Step-by-step explanation:
The sum of all exterior angles of any quadrilateral= 360°
3x+2x+40+x+50+4x = 360°
11x + 90 = 360°
11x = 360 - 90
10x = 270
x = 270/10
x = 27
