So all the angles on one side should equal 180.
50+55= 105
180-105=75
12x+3=75
12x=72
12*6=72
x=6

What is the value of x? Enter your answer in the box. units

Answer:

x = 28

Step-by-step explanation:

If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.

Then x/(x +10) = 42/(42 +15)

x(57) = 42(x + 10)

57x = 42x + 420

15x = 420

x = 28

NEED ANSWER ASAP!! Find x

sineoko [7]

Step-by-step explanation:

$\frac{48}{2x + 7} = \frac{40}{5x - 2} \\ 48(5x - 2) = 40(2x + 7) \\ 240x - 96 = 80x + 280 \\ 240x - 80x = 96 + 280 \\ 160x = 376 \\ \frac{160x}{160} = \frac{376}{160} \\ x = 2.35$

Answer:

$\large \boxed{\text{There is no solution}}$

Step-by-step explanation:

$\begin{array}{rcll}3x - 4 + 1 & = & -2x - 5 + 5x & \\3x - 3 & = & 3x - 5 & \text{Combined like terms on each side}\\-3 & = & -5 & \text{Subtracted 3x from each side}\\\end{array}\\\text{This is impossible. There is $\large \boxed{\textbf{no solution}}$ to the equation.}$

The ratio of oranges to apples in Helen's basket is 4:3. The basket has 12 apples in it. How many oranges are in the basket?

frez [133]

Answer:

16 oranges

Step-by-step explanation:

The ratio of oranges to apples is 4:3 which means that for every four oranges, there are 3 apples.

Since there are 12 apples in the basket, to find the number of oranges, set up a ratio.

4/3 = x/12 (x represents the number of oranges)

Cross multiply.

48 = 3x

Divide by 3.

x = 16

There are 16 oranges in the basket.

Hope that helps.
