Answer:

28x+8y+2

Step-by-step explanation:

-2\left(3x+12y-5-17x-16y+4\right) -> =-2\left(-14x-4y-1\right)

\mathrm{Distribute\:parentheses}

=\left(-2\right)\left(-14x\right)+\left(-2\right)\left(-4y\right)+\left(-2\right)\left(-1\right)

\mathrm{Apply\:minus-plus\:rules}\\\left(-a\right)\left(-b\right)=ab\\=2\cdot \:14x+2\cdot \:4y+2\cdot \:1\\=28x+8y+2

Solve for y. -2y=3x+10
patriot [66]

Answer:

y= -(3/2)x -5

Step-by-step explanation:

Divide both sides by negative 2

-2y=3x+10

This halves the 3 and the 10 resulting in (3/2) and 5 values, since they are positive integers dicided by a negative integer they become negative. Negative 2 divided by begative two becomes positive 1 since negatives cancel each other out.

y= -(3/2)x -5

Which mized numbers can you write for 24/7
IgorLugansk [536]
How many times does 24 go into 7?

7 × 1 = 7
7 × 2 = 14
7 × 3 = 21
7 × 4 = 28

7 goes into 24 only three times, leaving three remainder. So you would write it like this: 3 \frac{3}{7}. 7 goes into 24 three times, there is three left over as remainder, and the denominator from before is 7. Thus the answer.

I do hope this helped :))

The formula for the area of a triangle is A=12bh. Solve this equation for b.
aksik [14]

Step-by-step explanation:

Hey there!

Given;

[A = 1/2b*h]

Divide both sides by 'h'.

A/h = 1/2(b*h/h) [ on right side'h' gets cancelled].

Multiply '2' and 'A'.

A*2/h = b

b = 2A/h.

want to get rid of 14 from each side so 14 - 14 would get rid of that 20 - 14 = 6 now you still have a negative 2x

-2x / -2x gives you X to be alone now divide 6 with -2 which gives you -3
