Answer: fin the bottom half by multiplying 10 by 20 which gives you 200 then find the top half with the formula for a trapezium so it would be 2x (1/2(14+20)) in this case the 2 and the half cancel eachother out so you end up with 34. then add the 2 halves together so 34+200=234 and theres your answer

3x + 4y =10 6x -2y = 40

Answers

Simplifying

3X + 10 = 6X + 40

Reorder the terms:

10 + 3X = 6X + 40

Reorder the terms:

10 + 3X = 40 + 6X

Solving

10 + 3X = 40 + 6X

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '-6X' to each side of the equation.

10 + 3X + -6X = 40 + 6X + -6X

Combine like terms: 3X + -6X = -3X

10 + -3X = 40 + 6X + -6X

Combine like terms: 6X + -6X = 0

10 + -3X = 40 + 0

10 + -3X = 40

Add '-10' to each side of the equation.

10 + -10 + -3X = 40 + -10

Combine like terms: 10 + -10 = 0

0 + -3X = 40 + -10

-3X = 40 + -10

Combine like terms: 40 + -10 = 30

-3X = 30

Divide each side by '-3'.

X = -10

Simplifying

X = -10

Carmela is growing her hair to donate to a charity. The hair must be a minimum length of 10 inches. Her hair is already 4 inches long. If hair grows at the rate of 6 inches a year, write and solve an inequality to find the minimum number of years she must grow her hair to be able to make a donation.

I think that would work.

Solve for u -5/2u = 15

Answers

Answer:

U = -1/6

How to solve:

Multiply both sides by 2U to get rid of the denominator and you should end up with

- 5 = 15(2u)

then multiply and devide to get your U by itself.

you should then get

u =  -  (1)/(6)

after symplifying.

Answer:

Answer:

u=−10

Step-by-step explanation:

Let's solve your equation step-by-step.

u−5/2u=15

Step 1: Simplify both sides of the equation.

u−5/2u=15

u+−5/2u=15(u+−52u)=15

(u+−52u)=15(Combine Like Terms)

−3/2u=15

−3/2u=15

Step 2: Multiply both sides by 2/(-3).

(2−3)*(−32u)=(−3)*(15)

u=−10

What is 7 divided by 2/3? (Need this done quickly)

Answers

Hi there! We make 7 a fraction, 7=7/1 and we change the division sign into a multiplication sign, we flip 2/3 into 3/2. Now, we have a multiplication problem of 7/1*3/2. 7*3=21 and 1*2=2, now we have a fraction of 21/2. 21/2 as a mixed number is 10 1/2. Therefore, the answer is 10 1/2

Dr. Stein bought 30 notebooks, 60 pencils and 300 erasers for his class to make identical packages with some notebooks, some pencils and some erasers for his students. He used everything he bought, and every student got a package. What is the largest number of students Dr. Stein can have in his class?

Answers

There are 30 students

The key word is "identical." If all students received identical packages, then Dr. Stein could have handed out 30 packages. He has a maximum of 30 notebooks to hand out, so if each package has one notebook, he can hand out 30 packages. Each of those 30 packages will also have 2 pencils and 10 erasers.

ANSWER: There are 30 packages maximum so he can have a maximum of 30 students.

Hope this helps! :)
