Hi there!

The next step is most likely the following:
3x = 18

This is because you add up 3 on both sides on the equation.

Answer:

Next step would be 3x=18

Step-by-step explanation:

We have given some steps to find the value of value of x and we have to evaluate the next step.

Step 3 is given by

$3x-3=15$

3 is in subtraction with 3x. Hence, in order to get rid of 3 from the left hand side, we can do the reverse operation of subtraction.

The reverse operation of subtraction is addition.

Hence, add 3 to both sides of the equation.

$3x=15+3\\3x=18$

Thus, the next step would be 3x=18

A line parallel to the x-axis could contain which point? Choose all that apply. A. (-10,4) B. (2,0) C. (0,2) D. (4,0) E. (0,0) F

zzz [600]

Answer:

The points (2,0), (4,0), and (0,0) are on the line which is parallel to the x-axis.

Step-by-step explanation:

If a line is parallel to the x-axis then, the x-coordinate changes but the y-coordinate remain constant.

Now, in the points (2,0), (4,0), and (0,0) the y-coordinate remains the same but is equal to 0.

Since x-axis itself is a parallel to the x-axis with distance fro the x-axis equal to zero.

Therefore, the points (2,0), (4,0), and (0,0) are on the line which is parallel to the x-axis. (Answer)

Sally deposits 4000 in a certificate of deposit that pays 6.94% simple interest.What is her balance after one year?

nadezda [96]

Answer:

4277.6

Step-by-step explanation:

Hello, I can help you with this

Step one

find the profit using a simple rule of three

4000 ⇔ 100%

then, how much(x) is 6.94?

x ⇔ 6.94%

the relation is

$\frac{4000}{100}=\frac{x}{6.94}\\ solve\ for\ x\\\\x=\frac{4000*6.94}{100}\\x=277.6\\$

the profit is 277.6

hence, her balance after one year is the initial amount plus interest earned

balance= 4000+277.6

balance= 4277.6

I hope it helps, Have a great day

You measure a sheet of paper. The width is 8.47 inches and the length is 10.98 inches. What is the area of the paper in mks unit

Hoochie [10]

SOLUTION - GIVEN

Width = 8.47 inches

Length = 10.98 inches

FIND OUT - Area of a paper in mks units.

TO PROOF - Paper shape is like rectangle.

Formula

Area of a rectangle = length × breadth

= 10.98 × 8.47 $inches^2$

= 93.0006 $inches^2$

Now we require answer in mks units.

( mks units stand for the length in meter, mass in kilogram & time in

seconds.)

That means we require answer in meter unit.

1 inches = 0.0254 meter

Area of a paper = 93.0006 × 0.0254 × 0.0254 $meter^2$

= 0.0600002671 $meter^2$

Hence proved
