Can someone help me on 2/3-3/8 show work

Answers

Answer:

It is 7/24

Step-by-step explanation:

So first you want a common denominator so we have to find the least common multiple of 3 and 8, which is 24.

Next you have to multiply the same to the numerator, I usually go by the phrase whatever you do to the bottom you do to the top. So 8 times 2 is 16 and 3 times 3 is nine.

Everything changed should be 16/24-9/24

then we do 16-9 is 7 and you never subtract the denominators so 2/3-3/8 is 7/24

Answers

answer: x=10 and y=15

solve x-5y=-30, 3x+5y=10 show your work

Answers

1) x = 5y - 30  

2) x = - 1.6y + 3.3

im assuming these are 2 different questions

Explanation:1)

Start with the equation:

x - 5y= -30

add 5y to both sides:

x = 5y - 30

Your answer is x = 5y - 30  

2)

Start with the equation:

3x+5y=10

subtract 5y from both sides:

3x = -5y + 10

divide by 3 to get x singular

x = - 1.6y + 3.3

Your answer is x = - 1.6y + 3.3

Hope this helps :)

The area of a circle is 379.94m². Using 3.14 for π, find the circumference of the circle.

Answers

Answer:

69.08

Step-by-step explanation:

The equation for circumference is C = 2πr and the equation for area is A = πr^2. First, do 379.94 = 3.14r^2. This means that r^2=121 so r=11. Now plug it in to C=2πr so it becomes C=2π(11). So C=22π or 69.08.

Question:

Find the circumference of the circle. Use 3.14 for π.

5 in.

Answer:

15.7 inches

Step-by-step explanation:

Identify the diameter of the circle.

d = 5 in.

Use the formula.

C = πd

C = π(5) Substitute 5 for d.

C ≈ 3.14(5) Substitute 3.14 for π.

C ≈ 15.7 Multiply.

The circumference of the circle is about 15.7 inches.

HELP, NO SCAM ANSWERS PLEASE!

Answers

Answer:

c = 2.99m+ 6.85

Step-by-step explanation:

one time fee of 6.85

2.99 per movie rental

in other words you must pay 6.85

and 2.99 times the number of movies you watch

m = movies watched

c = cost

therefore

c = 2.99m+ 6.85

watching 13 movies at movie mania would mean that m (movies watched) would be 13

put that into the equation:

c = 6.85+ 2.99(13)

c =  6.85+ 38.87

c = 45.72

Step-by-step explanation:

Step 1: Define

-2x > -12

Step 2: Solve for x

Divide -2 on both sides:                    x < 6

Here we see that any value x smaller than 6 would work as a solution to the inequality.

Answer:

x < 6

Step-by-step explanation:

Hello!

We can solve inequalities the same way as we solve equations. The most important rule is that when you divide or multiply both sides by a negative number, flip the sign.

Solve for x-2x > -12-2x / -2 < -12 / -2      (flip the sign!)x < 6

The solution set for x is all values less than 6.
