0.25(x + 4) - 3 = 28

Answers

Answer 1

Answer:

x = 120

Step-by-step explanation:

0.25(x + 4) - 3 = 28

Multiply 0.25 into the parenthesis

0.25x + 1 - 3 = 28

Combine like-terms

0.25x - 2 = 28

Add 2 to both sides

0.25x = 30

Divide both sides by 0.25

x = 120

Answer 2

The answer is 120

0.25(x+4)-3=28
0.25x+1-3=28
0.25x-2=28
0.25x=30
x=120

Answer:

g=2-X/-3

Step-by-step explanation:

X=3g+2

To make g the subject, make it stand alone

While transferring 3g to the other side of the equation, the sign changes i.e + changes to -

The equation will then be written as: -3g = -X + 2 or -3g = 2 - x

Divide both sides by -3

g= (2-x)/-3

Help Ill give 100 points!

Answers

Answer:

0, 1, 1/2

Step-by-step explanation:

First you would have to make them have the same denominators.

The lowest one they share is 24.

What ever you do to the bottom you have to do to the bottom.

1/6, times each by 4.

1 * 4 = 4

6 * 4 = 24

4/24.

Now you have to do the same thnig for 5/8.

But times it by 3, since 8 times 3 is 24.

5 * 3 = 15

8 * 3 = 24

15/24

Now subtract.

15 - 4 = 11/24

the difference is close to one half.

4/24 = 1/6 is close to 0.

15/24 = 5/8 is close to 1.

In right triangle ABC, m∠B ≠ m∠C. Let sin B = r and cos B = s. What is sin C – cos C?

Answers

Answer: s - r

==================================================

Explanation:

We'll need these trig ratios

sine = opposite/hypotenusecosine = adjacent/hypotenuse

Refer to the diagram below.

sin(B) = r = r/1 which tells us that the side opposite angle B is r units long. The hypotenuse is 1.

cos(B) = s = s/1 means the adjacent side to angle B is of length s

sides r and s are the two legs of the right triangle.

----------

From that diagram, we can then say:

sin(angle) = opposite/hypotenuse

sin(C) = s/1

sin(C) = s

This is identical to cos(B). We can say cos(B) = sin(C)

Also, we can say:

cos(angle) = adjacent/hypotenuse

cos(C) = r/1

cos(C) = r

So cos(C) = sin(B)

This works because B+C = 90

----------

So,

sin(C) - cos(C) = cos(B) - sin(B) = s - r

131 minutes, an = 15 + (n - 1)(4)

Step-by-step explanation:

each time she is increasing by 4 minutes

we can write this equation like this since we have the difference and the first part:

an = 15 + (n - 1)(4)

note

"an" (or ace of n)'s n is in subscript and is written just like a superscript but on the bottom

we can plug in this equation to find ace of 30 (a30)

15 + (30 - 1)(4)

15 + 29*4

116 + 15

a30 = 131
