8 0

\bf Step-by-step~explanation:

\bf Step~1:

To solve this, we have to simplify these numbers by adding like terms.

42x^2+34-8-12\\\\(34-8=26, 26-12=14)\\\\42x^2+14\\

\bf Step~2:

Next, we factor our expression. To do so, we look for the greatest common factor of 42 and 14, which is 14. We know that because 42 divided by 14 is 3.

\frac{42}{14} =3

\boxed{ \bf Our~final~answer: 14(3x^2 + 1)}

Solve 5/4y-18=y/2<br> pls solve it <br> i'll mark you as brainliest
Volgvan

Answer:

y = 24

Step-by-step explanation:

5/4y-18=y/2

Multiply by 4 on all sides to get rid of the fractions

4(5/4y-18)=4*y/2

5y - 72 =2y

Subtract 5y from each side

5y-5y - 72 =2y-5y

-72 = -3y

Divide by -3

-72/-3 = -3y/-3

24 =y

What is the answer??????​
Lina20 [59]

Answer:

<h2>1) B. 1 1/32</h2>

<h2>2) A. 1.8</h2>

Solution:

2 3/4 as an improper fraction is 11/4.

2 2/3 as an improper fraction is 8/3.

11/4 ÷ 8/3

11/4 ÷ 3/8 (reciprocal method)

11/4 × 3/8 (change the operation to multiplication)

11/4 × 3/8 = 33/32 (multiply)

33/32 ⇒ 1 1/32 (simplify)

1 4/5 as an improper fraction is 9/5.

9/5 ⇒ 1.8
