PLEASE HELPP

Answer:

d = 9/10

Step-by-step explanation:

Hi,

d divided by 5/6 = 3/4

You can't divide fractions, instead, you flip the fraction and multiply. So, in this case, you would flip 5/6 to get 6/5 and multiply it by 3/4 to get d.

d ÷ 5/6 = 3/4

Multiply both sides by 6/5 (remember to flip)

d = 3/4 x 6/5

(when multiplying fractions, you can multiply straight across)

d = 18/20

(simplify - both numbers can be divided by 2)

d = 9/10

Hope this helps :)

2(x - 5) + 7 = x + 8 what is x represents

Misha Larkins [42]

Answer: $x=11$

Reorder the terms in parentheses

$+(+2x-10)+7=x+8$

Remove unnecessary parentheses

$+2x-10+7=+x+8$

Move all terms containing x to the left and all other terms to the right

$+2x-1x=+8+10-7$

Simplify left and right side of the equation

$+1x=+11$

divide both sides of the equation by 1 to get x

$x=11$

Answer:

D.) This system has no solutions (The one you chose is correct)

Step-by-step explanation:

y = 8x + 9

-8x + y = -1

y = 8x - 1

These two lines will also never meet as the slope are both 8, but the y-intercept is different, to check, look at the graph below.
