X=75

Step-by-step explanation:

FD/DJ=SJ/YJ=FS/DY(BEING CORESSPONDING SIDE OF SIMILAR TRAINGLES)

TAKING FIRST AND SECOND RATIO

OR X/50=63/42

OR X*42=63*50

OR X=3150/42

OR X=75

Answer:

x=75

Step-by-step explanation:

∆FSJ~∆DYJ

so the sides are proportional

SJ/YJ=FJ/DJ

(63+42)/42=(x+50)/50

105/42 ×50=x+50

125-50=x

x=75

Oksanka [162]

Answer:

10 green and 1 blue pencils

Step-by-step explanation:

Exactly 11 pencils were added

Blue pencils became highest, for it to be highest, it has to be more than all the other ones. So if 10 is added to the original number it will make it 13 higher than all, and the remaining one is added to green to make it 12 higher than red.

Can you help me solve and describe the steps used to find x for the equation 2(x + 4) – 10 = 12

Anettt [7]

Hi there!

To solve, let's rewrite this equation.

$2 (x + 4) - 10 = 12$

Step 1) Simplify both sides of the equation.

$(2) (x) + (2) (4) + - 10 = 12 2x + 8 + - 10 = 12$ (Distribute)

$(2x) + (8 + - 10) = 12$ (Combine Like Terms)

$2x + - 2 = 12 2x - 2 = 12$

Step 2) Add 2 to both sides.

$2x - 2 + 2 = 12 + 2 2x = 14$

Step 3) Divide both sides by 2.

$\frac{2x}{2} = \frac{14}{2}$

$x = 7$

Final Answer -

$x = 7$

Hope this helps!
