Answer:
Son age be 10
And, the father age be 40
Step-by-step explanation:
The computation of the present ages is shown below:
Let us assume the son age be x
And, the father age be x + 30
Now after five hence, their ages are
Son age = x + 5
And, the father age be = x + 30 + 5
Also the father age is thrice of his son age
So the equation would be
3(x + 5) = x + 35
3x + 15 = x + 35
2x = 20
x = 10
The son age is 10
And, the father age is = 10 + 30 = 40
The correct ans is Five,
Let the son’s present age be x years.
Then the father’s present age is (x+30) years.
Father’s age after 5 years =(x+40) years
Son’s age after 5 years = (x+5) years
(x+40) = 3[x + 5]
x + 40 = 3x + 15
2x = 10
∴ x = 5

Find the area of the figure above.
Answer:
84
Step-by-step explanation:
You do problems like these by finding the area of each shape individually and then adding them together. I first found the area of the rectangle by multiplying 6 in. by 11 in. to get 66 in.^2. I then found the area of the triangle by multiplying length of the base of the triangle which is the same as the short side of the rectangle at 6 in. by the 6 in. height and dividing it by 1/2. This gets 18 and 66+18=84

Randeep purchased sandwiches and a gallon of milk for himself and his friends. Each sandwich cost $8. The gallon of milk cost $4. The total cost of the meal was $44. Which answer choice represents and solves correctly the equation for x, the number of sandwiches that Randeep purchased? DON'T FORGET THE NUMBER OF SANDWICHES RANDEEP MUST BUY TO REACH $44.
Answer: He bought 5 sandwiches.
Step-by-step explanation:
We know that he purchased sandwiches (let's suppose that he bought X ) and one gallon of milk.
The cost of each sandwich is $8, then the cost of the X sandwiches will be X times $8, or: X*$8.
The cost of the gallon of milk is $4.
The total cost will be:
$4 + X*$8.
And we know that the total cost was $44, then we have the equation:
$4 + X*$8 = $44
We can solve this for X
X*$8 = $44 - $4
X*$8 = $40
X = $40/$8 = 5
This means that he bought 5 sandwiches

A chess club with 25 members is electing a new president. Abdul received 23 votes. What percentage of the club members voted for Abdul?
Answer
92%
Explanation
23 out of 25 people voted Abdul.
So that means [tex]\frac{23}{25}[/tex] people voted Abdul.
When you divide 23 by 25 you get 0.92 which is 92% (multiply by 100).
You divide because a fraction means the numerator divided by the denominator.

Answer:
The amount of fruit syrup Rex added is: 3 liters
and the amount of water he added is: 4 liters.
Step-by-step explanation:
3y = 2x + 6
x + y = 7
y = 7 - x
3(7 - x) = 2x + 6
21 - 3x = 2x + 6
21 - 6 = 2x + 3x

x + y = 7
3 + y = 7
y = 7 - 3

En un triangulo rectángulo, uno de los catetos mide 54 dm y su proyección sobre la hipotenusa, 32,4 dm. Calcula la medida de la hipotenusa
Answer:
63 dm (aproximadamente)
Explicación paso a paso:
Dada a medida dos dous lados do triángulo: 54 dm e 32,4 dm.
Dado que se afirma que o terceiro lado é o hipoteno, que é o lado máis longo dun triángulo rectángulo, o hipoteno (h) pódese obter así:
h = sqrt (54 ^ 2 + 32,4 ^ 2)
h = sqrt (2916 + 1049,76)
h = sqrt (3965,76)
h = 62,974280
h = 63 dm (aproximadamente)

The cost of a cheese pizza is $9.99 plus $0.35 for each additional topping, t .
Write an inequality that can be used to represent the cost of a pizza that is at most $12.
What is the most number of toppings that a pizza can have and still be at most $12?
Step-by-step explanation:
$9.99 + $0.35t <= $12
$0.35t <= $2.01
t <= 5.74
The most number of toppings would be 5.
Answer:
9.99 + 0.35t ≤ 12
5 toppings
Step-by-step explanation:
First part of question:
9.99 + 0.35t ≤ 12
"At most" means you use ≤.
Second part of question:
Take the inequality and solve for t:
9.99 + 0.35t ≤ 12
0.35t ≤ 2.01
t ≤ 5.74
So, the most number of toppings that a pizza can have and still be at most $12 is 5 toppings. You have to round down 5.74 to 5 otherwise the cost will exceed $12.

Multiply through by 6(x - 1)(x + 1) [ the LCM of the denominators ]
6(x + 1)² - 6(x - 1)² = 5(x - 1)(x + 1) ← expand factors and simplify
6(x² + 2x + 1) - 6(x² - 2x + 1) = 5(x² - 1)
6x² + 12x + 6 - 6x² + 12x - 6 = 5x² - 5
24x = 5x² - 5 ( subtract 24x from both sides )
0 = 5x² - 24x - 5 ← in standard form
0 = (x - 5)(5x + 1) ← in factored form
Equate each factor to zero and solve for x
5x + 1 = 0 ⇒ 5x = - 1 ⇒ x = - [tex]\frac{1}{5}[/tex]
x - 5 = 0 ⇒ x = 5

Step-by-step explanation:
x= -3.6 y= 14.4
HOW I SOLVED IT
-3.6 x 3 = -10.8 2 x 14.4 = 28.8 - 10.8 = 18 so correct since it must equal to 18
-2/3 x -3.6 =2.4 + 12 = 14.4 so correct since y = 14.4
