Answer:

x = 5

Step-by-step explanation:

Sides of large triangle: 4x and 15

Corresponding sides of small triangle: 3x + 1 and 12

$\dfrac{4x}{15} = \dfrac{3x + 1}{12}$

$60 \times \dfrac{4x}{15} = 60 \times \dfrac{3x + 1}{12}$

$16x = 15x + 5$

$x = 5$

What is the value of x in the equation 4(2x − 1) = 2x + 35?

Grace [21]

Answer:

x = 6.5 or 13/2

Step-by-step explanation:

4(2x − 1) = 2x + 35

distribute the 4 to 2x - 1

8x - 4 = 2x + 35

subtract 2x

6x - 4 = 35

add 4

6x = 39

divide by 6

x = 6.5 or 13/2
