PLEASE HELPPPP<br><br> 4(x−2 1/4)=−3.7
LekaFEV [45]

First let’s convert the mixed numbers to improper fractions 2 1/4 =9/4
Then u get 4(X-9/4) =-3.7
Now your gonna divide both sides by four
4(X-9/4) over 4 = -3.7 over 4
4/4 =1 …X=-9/4
-3.7/4 = -0.925
Now you’re going to add 9/4 to each side
X-9/4+9/4=-0.925 +9/4
-9/4 + 9/4 =0 (X)
Now you have just -0.925 and nine fourths
I converted 9/4 —> 2.25
Then u still have -0.925
So add 2.25+-0.925 u get ur X which is 1.325 (this is ur answer)

What is the first step in solving the quadratic equation x^2=9 over 16
nikdorinn [45]

Answer:

"Take the square root of both sides of the equation"

A is correct

Step-by-step explanation:

We are given quadratic equation

We need to solve for x. We have to isolate x here.

Here square on x. So, first we get rid of square.

Taking square root both sides to get rid of square.

For example:

a2=25

sqare a2  = +- sqare 25

x2=9/16 to solve for x

sqare x2 +- sqre 9725

x=+- 3/5

Hence, "Take the square root of both sides of the equation"

Put these numbers in order from greatest to least.<br> 9, 9/10, -18/36, 28/40 Please help me
mojhsa [17]

Answer:

9>0.9>0.7>-18/36

Step-by-step explanation:

the smallest would be -18/36.

now we have 9,9/10,28/40

simplify 9/10: 0.9

simplify 28/40: divide 28 and 40 by 4. you will have 7/10 which is equal to 0.7.

now the greatest number is 9,then 0.9 and then 0.7

if anything is unclear, ask freely.
