The age of the father is 42, the age of the son is 9. After how many years will the father be twice as the age of the son?
Answer:
24 years
Step-by-step explanation:
First, I will set up an equation.
2(9 + x) = 42 + x
18 + 2x = 42 + x
x = 24
9 + 24 = 33
42 + 24 = 66
66 is 2 times 33.

Answer:
$66.50
Step-by-step explanation:
Given Us that:
⇒ Video game: $70 Sale: 5% off
To Find:
What is the new cost of the video game?
Note:
Off ⇒ Discount ⇒ decrease ⇒ subtract
5% = 0.05
Solve:
⇒ $70 × 0.05 = 3.50
⇒ $70 - 3.50 = 66.50

Toby thinks of a number less than 15. He divides it by 2 and then he adds 4. He then divides it by 3. His answer is 3.5
Answer:
13
Step-by-step explanation:
For this problem, work backwards to determine what the starting number was. Take 3.5 and multiply it by 3 to get 10.5, then subtract 4 to get 6.5. Finally, multiply 6.5 by 2 to get the starting number, which is 13. To check your work, you can always take 13 and perform the operations to make sure you end up with 3.5.

In a highway building project, 32 miles of a new highway have been
completed. This is three miles less than one third of the entire length.
How long will the new highway be when completed?
Answer: 105 miles
Step-by-step explanation:
You can write an equation for this problem and solve it.
32 miles=1/3x-3, where x is equal to the total length of the highway.
35=1/3x, and then you multiply by 3, to get x=105

What is a perfect square monomial?
A perfect square is an expression that factors into two other expressions that are identical. A monomial is a single phrase made up of a product of constants, variables, and their positive integer powers. As a result, a perfect square monomial is a monomial that factors into two monomials that are identical.
As given to us that the first row consists of tile 2x², and the second row also consists of tile 2x². Thus, the expression can be written as,

Antonio has just graduated from four years of college. For the last two years, he took out a Stafford loan to pay for his tuition. Each loan had a duration of ten years and interest compounded monthly. Antonio will pay each of them back by making monthly payments, starting as he graduates. Antonio’s loans are detailed in the table below. Year Loan Amount ($) Interest Rate (%) Subsidized? Junior 5,894 6. 9 Y Senior 5,258 7. 5 N Once all of his loans are paid off, what will Antonio’s total lifetime cost be? Round all dollar values to the nearest cent.

Antonio’s total lifetime cost will be $11680.99 after calculating all loans
What will be Antonio’s total lifetime cost?Given that
Loan Amount ($)
5,894$
5,258$
Interest Rate (%)
6.9%
7.5%
Now for the loan amount 5,894$ at 6.9% interest, the amount will be
[tex]A=P(1+\dfrac{r}{h} )^{n\times t}[/tex]

[tex]A=5258\times2.1120=111105.23[/tex]
So the total lifetime cost will be

Answer:
8) width = 30 cm
length = 60 cm
9) first side = 60 m
second side = 180 m
third side = 240 m
Step-by-step explanation:
Question 8
Let W = width
Given:
length of a rectangle is 30 cm less than 3 times the width⇒ Length = 3W - 30
Given:
Perimeter = 180 cmPerimeter of a rectangle = 2W + 2L
(where W is the width and L is the length)
Substituting equation for length into the equation for the perimeter and solving for W:
Perimeter = 2W + 2L
⇒ 180 = 2W + 2(3W - 30)
⇒ 180 = 2W + 6W - 60
⇒ 240 = 8W
⇒ W = 30 cm
Substitute found value of W into the equation for length and solve for length:
⇒ Length = 3(30) - 30
⇒ Length = 90 - 30
⇒ Length = 60 cm
Question 9
Given:
The second side is 3 times the first and the third side is 60 m more than the second.Let x = first side
⇒ second side = 3x
⇒ third side = 3x + 60
Given:
Perimeter of triangle = 480 mPerimeter = sum of length of all sides
⇒ 480 = x + 3x + 3x + 60
⇒ 420 = 7x
⇒ x = 60
Therefore,
first side = 60 m
second side = 3 × 60 = 180 m
third side = 3(60) + 60 = 240 m
width be x
length=3x-30
Now
2(3x-30+x)=1804x-30=904x=120x=303x-30=60°#2
sides be x,3x,3x+60
Now
x+3x+3x+60=4807x=420x=60°Hence

What is the solution set for 2x^2+15=-11x
Answer:
x = {-3, -2.5}
Step-by-step explanation:
Simplifying
3 + x = 0
Solving
3 + x = 0
Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + x = 0 + -3
Combine like terms: 3 + -3 = 0
0 + x = 0 + -3
x = 0 + -3
Combine like terms: 0 + -3 = -3
x = -3
Simplifying
x = -3
Simplifying
5 + 2x = 0
Solving
5 + 2x = 0
Move all terms containing x to the left, all other terms to the right.
Add '-5' to each side of the equation.
5 + -5 + 2x = 0 + -5
Combine like terms: 5 + -5 = 0
0 + 2x = 0 + -5
2x = 0 + -5
Combine like terms: 0 + -5 = -5
2x = -5
Divide each side by '2'.
x = -2.5
Simplifying
x = -2.5

On a trip Joel drove 25 miles more than half the number of miles
Rita drove. Together they drove 340 miles. How many miles did
Joel drive?
Answer:
194
Step-by-step explanation:
you would do 340 divided by 2 and that gets you 170 then you would subtract 24 from Rita and that is 146 so Rita drove 146 miles. then for Joel you add 170 +24 = 194. So Joel drove 194 miles.

11y=7
divide both sides by 11
y=7/11

x-a divides the polynomial where a is a zero of polynomial:
So x+4 divides [tex]2x^{3} +2x^{2} -19x+20[/tex]
If we factor out a two, we can use the quadratic formula.
2(x^2-3x+2.5) so we have x = (-(-3)+/-(9-4*1*2.5)^(1/2))/2*1)=(3+i) or (3-i)/2 .
Final answer:

If Event A is "the card is a face card" and Event B is "the card is a spade," demonstrate the equation holds true.
/ 52 = / 13 × / 52
The demonstration of the equation is an illustration of probability
The complete demonstration of the equation is:
3/52 = 3/13 * 13/52
How to demonstrate the equationIn a standard deck, we have the following parameters:
Event A = Face card = 12
Event B = Spade =13
Number of cards = 52
So, the probability that a card is a spade and a face card is:
P(A and B) = P(A) * P(B)
This gives
P(A and B) = 12/52 * 13/52
Simplify
P(A and B) = 3/13 * 13/52
Further simplify
P(A and B) = 3/1 * 1/52
Multiply
P(A and B) = 3/52
So, the complete demonstration of the equation is:
3/52 = 3/13 * 13/52
