One fifth of a number plus three times the number is equal to 42 Moré than twice the number. Whats the number

Answers

Answer:

35

Step-by-step explanation:

Let number = x

(1/5 of x) + (3 * x) = 42 + (2 * x)

x/5 + 3x = 42 + 2x

1/5x + 3x - 2x = 42

1 1/5x = 42

6/5 x = 42

x = 42 ÷ 6/5

x = 42 * 5/6

x = 210 / 6

x = 35

The number is 35

Equation:
X=

Answers

Answer:

Step-by-step explanation:

Half the area of the rectangle shown is 24 square inches. Then value of x is 6

What is Area of Rectangle?

The area of Rectangle is length times of width.

Area = length x width.

24 = (x + 2)(x - 3) = x² - x - 6

x² - x - 30 = 0

(x + 5)(x - 6) = 0

We can eliminate the root x = - 5 because dimensions cannot be negative. So, the only valid answer is x = 6

The length = x + 2 = 6 + 2 = 8 in.

The width = x - 3 = 6 - 3 = 3 in

Hence, the value of x is 6.

Answers

Answer:

t_10 = 59049 x^25

Step-by-step explanation:

a = 3x^7

r = 3 x^2

t_10 = (3x^7)(3x^2)^10

t_10 = 3x^7 3^(10-1) * (x^2)^(10 - 1)

t_10 = 3x^7 * 3^9 * (x^2)^9

t_10 = 3x^7 * 19683 x^18

Answer:

x= 40 degrees

Step-by-step explanation:

The two angles inside must add up to 126, since the missing unknown angle is supplementary to 126 (where they add up to 180 degrees).

Thus

x + (2x+6) = 126

3x + 6 = 126

3x = 120

x = 40
