9514 1404 393

Answer:

14(x +5)

Step-by-step explanation:

The denominator of the first expression is ...

2x+10 = 2(x +5)

The denominator of the second expression is ...

7x +35 = 7(x +5)

The least common denominator (LCD) is the product of the unique factors in these denominators:

2×7×(x +5)

= 14(x +5) . . . . least common denominator

= 14x +70

Write the equation in standard form<br><br> y = -10x + 6

Mumz [18]

Step (1) Flip the equation

−10x+6=y

Step (2) Add -6 to both sides

−10x+6+−6=y+−6

−10x=y−6

Step (3) Divide both sides by -10

−10x−10=y−6−10

ANSWER
$x = \frac{ - 1}{10} y + \frac{3}{5}$

Margarita [4]

Answer:

= 221

Step-by-step explanation:

Lenght = 250

Width= x

Perimeter = 2 (l+b) = 942

2 x (250 +x) = 942

500 + 2x = 942

2x = 942 - 500= 442

x = 442 /2 = 221

I hope Im right!!
