Answer:

9

Step-by-step explanation:

Hello, let me help you with this

in this case, all you have to do is put the values into the expression

Step 1

let

a=4

b=3

c=10

and the expression is

\frac{3a}{4b}-c\\

Step 2

put the value into the expression

\frac{3a}{4b}-c\\\frac{3*4}{4*3}-10\\\\\frac{12}{12}-10\\\\\\ 1-10=9\\

I really hope it helps, have a great day.

How many solutions does the following equation have?<br> |3x + 12| = 18 (5 points)
DedPeter [7]

Answer: 2 solutions.

The given equation breaks down into these two equations

3x+12 = 18 and 3x+12 = -18

Basically 3x+12 equal to plus 18 and minus 18. This is due to the fact that something like |x| = 7 means x = 7 or x = -7, ie those x values are exactly seven units away from zero on the number line.

If you want to solve each equation, then

3x+12 = 18

3x = 18-12

3x = 6

x = 6/3

x = 2 is one solution

and

3x+12 = -18

3x = -18-12

3x = -30

x = -30/3

x = -10 is the other solution

I need yo help B, on dis question
Anna71 [15]
For this case we can use the law of the sine to solve the problem.
 We have then:
 5 / sine (68) = 5 / sine (x)&#10;
 From here, we clear the value of x.
 We have then:
 sine (x) = (5/5) * (sine (68))&#10;
 Rewriting we have:
 sine (x) = (1) * (sine (68))&#10;&#10;sine (x) = sine (68)&#10;&#10;x = arcsine (sine (68))&#10;&#10;x = 68
 Answer:
 
The angle R is given by:
 
x = 68 degrees

9. What is the relationship between the estimates you found for the lengths of the two equators?4 grade student
Ann [662]

7. You have the equator's length of four planets, the distances are given in kilometers

8. Estimation for the Earth: 40.000 km. Jupiter: 400.000. These approximations come from the nearest whole number for each.

9. The relation is that if the Jupiter equator's length is divided by ten, you will get the Earth's equator length, which means that Jupiter's equator is ten times bigger than the earth.
