A father is 35 years more than his son’s age. After 5 years the father’s age will be twice of his son’s age.Find the present age of both.
The son is 30 years and the father is 65 years.
Let x represent the present age of the son and y represent the present age of the father.
Hence:
y = x + 35
-x + y = 35 (1)
In 5 years time:
y + 5 = 2(x + 5)
y + 5 = 2x + 10
-2x + y = 5 (2)
Solving equations 1 and 2 simultaneously gives:
x = 30, y = 65
The son is 30 years and the father is 65 years.

Son = 30 years
Father = 65 years
Present Details:
Son: "s" years (lets consider son's present age to be s)
Father: "s + 35" (father is 35 years older than the son)
After 5 years:
Son: "s + 5" [son will be 5 years older]
Father: 2(s + 5) [twice the son's age] and (s + 35) + 5 = (s + 40) years
Solve father's age simultaneously:
2(s + 5) = (s + 40)2s + 10 = s + 402s - s = 40 - 10s = 30⊕ Thus, the Son is 30 years old.
Father's age:
s + 35 ⇒ 30 + 35 ⇒ 65 years2(4w+7)=62
Whats the answer how do I do it?
[tex]2(4w + 7) = 62[/tex]
Divide both sides by 2
[tex] \frac{2(4w + 7)}{2} = \frac{62}{2} \\ [/tex]
[tex]4w + 7 = 31[/tex]
Subtract both sides 7
[tex]4w + 7 - 7 = 31 - 7[/tex]
[tex]4w = 24[/tex]
Divide both sides by 4
[tex] \frac{4w}{4} = \frac{24}{4} \\ [/tex]
[tex]w = 6[/tex]
Answer:
w=6
Step-by-step explanation:
Step 1 : Simplifying
2(4w + 7) = 62
Step 2 : Recorder the terms :
2(7 + 4w) = 62
(7 * 2 + 4w * 2) = 62
(14 + 8w) = 62
Solving-
14 + 8w = 62
Solving for the variable 'w'
Move all terms containing w to the left side, all other terms to the right.
Add '- 14' to each side of the equation.
14 + - 14 + 8w = 62 + - 14
Combine like terms: 14 + - 14 = 0
0 + 8w = 62 + - 14
Combine like terms: 62 + - 14 = 48
8w = 48
Divide each side by '8'
W = 6
Simplifying
W = 6
The circumference of a circle is 12.56 feet. What is the circle's area?
[tex]\huge \sf༆ Answer ༄[/tex]
As we know, Circumference of the circle can be expressed as :
[tex] \large \boxed{ \: \: \: \: \: \sf2\pi r \: \: \: \: \: }[/tex]
where, r is the radius of the circle, now equate the expression with the given Circumference to find the Radius.
[tex] \sf2\pi r = 12.56[/tex][tex] \sf \: r = \dfrac{12.56}{2\pi} [/tex][tex] \sf \: r = \dfrac{12.56}{2 \times 3.14} [/tex][tex] \sf \: r = \dfrac{12.56}{6.28} [/tex][tex] \sf \: r = 2 \: \: ft[/tex]Therefore, it's radius is 2 feet.
Now, let's calculate its area using the formula ~
[tex] \large \boxed{ \: \: \: \: \: \: \sf \pi {r}^{2} \: \: \: \: \: \: }[/tex]
plug the value of r (radius) as 2.

3x - y = 23
2x + 3y = 8
Answer: x = 11
Step-by-step explanation:
You didn't state what you needed for these problems so I'm going to assume you need to solve for X.
1st Equation:
3x - y = 23 --> y = 3x - 23
2nd Equation:
2x + 3y = 8 --> (3y = 8 - 2x)/3 = y = 8/3 - 2x/3
Set Equations = to Each other
3x - 23 = 8/3 - 2x/3 --> 3x - 2x/3 = 8/3 + 23
9x/3 - 2x/3 = 8/3 + 69/3 --> 7x/3 =77/3
7x/3 X 3/7 = 77/3 X 3/7
x = 11
If you need to solve for y as well plug the x value back into the original equation and solve.

There are 4 Year 11 pupils in a football club, out of a total of 29 pupils.
Write this proportion as a percentage.
Give your answer correct to 1 decimal place when appropriate.
Answer:
14%
Step-by-step explanation:
So if we have 4 Year 11 pupils out of a total of 29 pupils at a football club, the fraction for that would be 4/29, if we convert 4/29 into a decimal number we get 0.13793103448, so we round this number up to the nearest 1 decimal place, and that would be 0.14 which equals 14%. Hope this helps.

What is the remainder when 3 is
synthetically divided into the polynomial -2x2 + 7x - 9?
A. -6
B. -4
C. 2
D. 0
The remainder when 3 is synthetically divided into the given polynomial is; Choice A; -6.
What is the remainder when 3 is synthetically divided into the polynomial?It follows from the task content that the remainder when 3 is synthetically divided into the polynomial is to be determined.
On this note, it follows that the expression evaluation at x = 3 represents the required remainder.
Therefore, we have;
-2 (3)² + 7 (3) - 9
= -18 + 21 - 9
= -27 + 21
= -6
Ultimately, the required remainder when 3 is synthetically divided into the polynomial is; -6.
Therefore, the correct answer choice is; Choice A; -6.

A floor is 40 m long and 15 m broad. It is covered with tiles, each measuring 60 cm by 50 cm. Find the number of tiles required to cover the floor.
Answer:
2,000 tiles
Step-by-step explanation:
area of the floor divided by the area of one tile
area of a rectangle is length*width
so it's 40*15= 600
area of tile is 0.6m*0.5m = 0.3
600÷0.3 = 2,000 tiles
