If your talking about decimals 2.1 then:

Step 1) Convert 2.1 into a fraction; 21/10

Step 2) Convert 21/10 into a mixed number. 10 can go in 21 2 times, leaving us with 1. 2 is the whole number and 1 is the numerator. 10 will continue to be the deniometor.

2 1/10

I hope I've helped!

D 1. Solve -4(3x - 7) = 40 for x.<br> x = -3.92<br> x= -1<br> X = 1<br> X = 3.92

<h3>ANSWER : </h3><h3></h3><h3> $x = -1$ </h3><h3></h3><h3> $\huge\bold{\textbf{\textsf{{\color{EXPLANATION :}{}}}}}$ </h3><h3></h3>

Solve for x, : $-4(3x-7) = 40 :~x = -1$

$-4(3x-7) = 40$

Divide both sides by : $-4$

$\frac{-4(3x -7)}{-4} =\frac{40}{-4}$

Simplify :

$3x - 7 = -10$

Add $7$ to both sides :

$3x -7~+~7=-10~+~7$

Simplify :

$3x = - 3$

Divide both sides by $3$ :

$\frac{3x}{3} =\frac{-3}{3}$

Simplify :

$x = -1$

Hope It Helps. . .

Brothers Raymond and Eduardo are saving up money to send their parents on an anniversary vacation. They have calculated that the

Advocard [28]

Given:

Money they've already saved = $270

Trip will cost at least $500.

To find:

The amount they need to save more in order to make enough for the trip.

Solution:

Let they need $x more.

Money they've already saved = $270

Total money they will have = $(x+270)

Now, the trip will cost at least $500. It means, they need $500 or more than that. So, total money they will have needs to be greater than or equal to 500.

$x+270\geq 500$

$x\geq 500-270$

$x\geq 230$

Therefore, they need $230 or more than that to make enough for the trip.
