Kevin is twice as old as his sister Amy their father is five times as old as Amy if the sum of the ages is 64 how old is Amy
Answer:
8 years old
Step-by-step explanation:
Set Amy's age as x.
Kevin's age will be 2x, since he is two times as old as Amy.
Father's age will be 5x, since he is five times as old as Amy.
x + 2x + 5x = Sum of the ages = 64
x + 2x + 5x = 64
Combine like terms: 8x = 64.
Divide 8 on both sides: x = 8.
Amy's age = 8.
Hope this helps!

7x(x-2y)
(2+1)(+5)
Step-by-step explanation:
7x(x - 2y)
= 7x.(x - 2y)
= 7x² - 14xy
= (2 + 1)(+5)
= (3)(5)
= 3 × 5
= 15
Step-by-step explanation:
1) 7x(x - 2y)
= (7x . x) - (7x . 2y)
= 7x² - 14xy
2) (2 + 1)(+5)
= 3(+5)
= (3 . +5)
= (3 . 5)
= 15

A class has 40 students. The teacher asks how many students in the class have siblings and finds 3/10 of the students have siblings. How many students have siblings?
Answer:
12 students
Step-by-step explanation:
First, find the percentage of how many students have siblings:
3/10 = 0.3 = 30%
40 * 0.3 = 12
This means that 30% of this class are 12 students. These 12 students have siblings.

Determine the slope and y-intercept of the linear function represented by the following scenario: Brooke and her friends decide to go bowling. The cost for the group is $15 for shoe rentals plus $4.00 per game.
The slope of the given scenario will be 4.
The y - intercept of the given scenario will be 15.
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The cost for the group is $15 for shoe rentals plus $4.00 per game.
Now,
Let number of games = x
And, Total cost of the bowling's = y
Here, The cost for the group is $15 for shoe rentals plus $4.00 per game.
So, We can formulate;
⇒ y = $4.00x + $15
⇒ y = 4x + 15
Compare with the standard form of equation of line y = mx + c, we get;
⇒ Slope = 4
And, The y - intercept = 15
Thus, The slope of the given scenario will be 4.
The y - intercept of the given scenario will be 15.

A greengrocer bought 200 kg of oranges for $180 and sold them for $1.14 per kg. Find
a. His profit.
b. His percentage profit on the cost price.
Answer:
profit : $28
profit percentage: 14%
Step-by-step explanation:
his profit : $1.14 times 200kg = $228
228 -200 = 28
28 divided by 200 = 0.14
0.14 times 10 = 14 %

HW 6.7 #11
Find the half-life of an element which decays by 3.418% each day. Hint: use y = ab^t.
First setup the equation for how much element is remaining after each day:
y = a ( 100% - 3.418%)^t
where y is the amount remainig and t is the number of days
We can clean this up by subtracting the percentages and converting that to a decimal:
y = a (0.96582)^t
Now for the half-life, we need to figure out how long until there's half of what we started with. When does "a (0.96582)^t" equal "1/2 of a"
1/2a = a (0.96582)^t
divide by a on both sides and you get
1/2 = (0.96582)^t
take the log of both sides and you get:
log(1/2) = t log(0.96582)
divide both sides by log(0.96582)
log(1/2) / log(0.96582) = t
Throw that into a calculator and you have
t ≈ 19.93
A t-shirt increased in price by 1/4. After the increase, it was priced at £65. What was the original price of the t-shirt?
Answer:
52
Step-by-step explanation:
Given:
1/4
Price at 65
Solution:
Let x be the original price
Based on the given conditions, formulate: [tex]x[/tex] ×[tex](1+\frac{1}{4} )=65[/tex]
Apply Multiplicative Distribution Law: [tex]x+\frac{x}{4} =65[/tex]
Multiply both sides of the equation by the common denominator: [tex]x[/tex]×[tex]4+\frac{x X4}{4} =65 X 4[/tex]
Reduce the fraction: x×4+x=65×4
Multiply the monomials: 4x+x=65×4
Combine like terms: 5x= 65×4
Calculate the product or quotient: 5x= 260
Divide both sides of the equation by the coefficient of variable: x = [tex]\frac{260}{5}[/tex]
Calculate the product or quotient: x = 52
get the result: x = 52
Answer: x = 52
