Output Variable: Earnings
Step-by-step explanation:
Given
Earnings = $3 per chore
Required
Determine the input and the output variables
The given parameter
Earnings = $3 per chore
i.e.
If he does 1 chore, he earns $3
If he does 2 chores, he earns $6
If he does 3 chores, he earns $9
---
--
-
If he does n number of chores, he earns $3n
So, we can conclude that:
His earning is dependent on the number of chores.

Mr Singh is paid £11.70 per hour after tax is deducted.
a) How much does he earn if he works 5 hours?
b) How much does he earn if he works 10 hours?
c) He works 37.5 hours per week.
How much does he earn in a week?
Please help!
Answer:
a) £58.5
b) £117
c) £438.75
Step-by-step explanation:
Mr Singh is paid £11.70 per hour after tax is deducted.
This means that for x hours of work, his earning are given by:
[tex]E(x) = 11.7x[/tex]
a) How much does he earn if he works 5 hours?
This is E(5).
[tex]E(5) = 11.7*5 = 58.5[/tex]
b) How much does he earn if he works 10 hours?
This is E(10).
[tex]E(10) = 11.7*10 = 117[/tex]
c) He works 37.5 hours per week. How much does he earn in a week?
This is E(37.5).
[tex]E(37.5) = 11.7*37.5 = 438.75[/tex]
Dennis is selling chocolate bars for a
fundraiser, and if he sells over $175 worth of
candy, he'll win a prize. If chocolates sell for
$2.50 a bar, and Dennis has already sold $40
worth of candy, then how many more bars does
he have to sell in order to win a prize? (Solve for x with inequalities)
Answer:
54 , 2.50x+40=175
Step-by-step explanation:
Answer:
2.5x + 40 > 175 (Dennis has to sell 55 chocolate bars)
Step-by-step explanation:
When you solve the inequality, you get...
2.5x + 40 > 175
Subtract 40 on both sides...
2.5x > 135
Divide 2.5 on both sides...
x > 54
When you substitute 54 for x in the original inequality you get...
175 > 175
Dennis needs to make more than 175 so he needs to sell 55 not 54.
Hope this helps :)

Least common denominator of 3/4 and 3/8
Answer:
8
6/8 and 3/8
4 = 2²
8 = 2³
LCM = 2 × 2 × 2
LCM = 8
The Least common denominator of the fraction numbers 3/4 and 3/8 is 9/24
What is least common denominator?The least common denominator (LCD) of 3/4 and 3/8 is the smallest number that both 4 and 8 can divide into evenly.
The prime factorization of 4 is 2 x 2, and the prime factorization of 8 is 2 x 2 x 2.
Next, we list the prime factors of each denominator and identify any factors that are common to both:
4: 2 x 2
8: 2 x 2 x 2
The common factors are 2 x 2, which means that we only need to include one set of these factors in the LCD.
So, the LCD of 3/4 and 3/8 is:
LCD = 2 x 2 x 2 x 3 = 24
For 3/4, we need to multiply both the numerator and denominator by 6 to get:
3/4 = (3 x 6)/(4 x 6) = 18/24
For 3/8, we need to multiply both the numerator and denominator by 3 to get:
3/8 = (3 x 3)/(8 x 3) = 9/24

Write the slope-intercept form of the equation of each line.
12x - 11y= 18
Answer:
y=[tex]\frac{12}{11}x[/tex]+[tex]\frac{-18}{11}[/tex]
Step-by-step explanation:
What you do first is you move the 12x to the other side of the equation to get
-11y=18-12x
Move the 12x to the front to get the slope intercept form set up
-11y=-12x+18
Then divide the whole thing by -11 to get the y to become by itself
y=[tex]\frac{12}{11}x[/tex]+[tex]\frac{-18}{11}[/tex]
The 12/11 will become positive and the b value will become negative

Zack has an old car. He wants to sell it for 15% off its current value. The market value is
$500. How much money would he receive in exchange for the car if he sells it at that rate?
425 dollars is 500 with a 15% discount
Answer:
$425
Step-by-step explanation:
The easiest way of calculating discount is, in this case, to multiply the normal price $500 by 15 then divide it by one hundred. So, the discount is equal to $75. To calculate the sales price, simply deduct the discount of $75 from the original price $500 then get $425 as the sales price.

Please hurry; Which function increases the fastest? A. y 5 14x B. y 5 23 · 17x C. y 5 120x D. y 5 2275x^x
a y = 14^x
b y = -3 (17)^x
c y = 120x
d y = -275x
Answer:The given equation is of the form y = mx + b where m is the slope and b is the y-intercept.
Here, m = -14
Two parallel lines have the same slope. So, the slope of the new line will be -14.
To calculate the y-intercept substitute x=4 and y=4 in the equation.
4 = (-14)(4) + b
Solving for b, we get b = 60.
So, the new equation will be y = -14x + 60

52 - 2y = -48
2x + 3y = -23
Answer:
y=50 and x=-173/2
Step-by-step explanation:
52-2y=-48
∴-2y=-100
y=50
and 2x+3y=-23
y=50→(1)
2x+3y=-23→(2)
Putting y=50 in equation (2), we get
⇒2x+3y=-23
⇒2x+3(50)=-23
⇒2x+150=-23
⇒2x=-23-150
⇒2x=-173
⇒x=-173/2
∴y=50 and x=-173/2
