HELP DUE IN 30 MINS! Leave Answers As Simplified Fractions If Necessary.z =??

Answers

Answer 1

Answer:

z = 15/4

Step-by-step explanation:

6/z = 8/5z = 6*5/8z = 30/8  z = 15/4
Answer 2

Answer:

z=15/4

Step-by-step explanation:

First you want to take z and multiple it by both sides:

6/ZxZ=8/6xZ

6=8z/6

Now you want to do the same thing with 5:

6x5=8z/5x5

30=8z

Now finally you divide both sides by 8 to get z alone:

30÷8=8z÷8

3.75=z

3.75=15/4

I hope this helps ❤️

125% of e is 30. What is e? e =
35% of f is 14. What is f? f =

Answers

Answer:

If 125% of e is 30, then 25% of e is 6. So then 100% of e would be 24

If 35% of f is 14, then 5% of f is 2. So then 100% of f would be 40

Answer:

Step-by-step explanation:

125% = 125/100 = 5/4

5/4 is 30, so 4/4 is 24. to check: multiply 5/4 and 24 together, you will get 30.

for the second: 28 would be 70%  or 7/10

28 divided by 7 is four so every ten percent would be 4. 4 times 10 would get you forty. 35 percent of fourty it equals 14.

THE FIRST ANSWER IS 24 THE SECOND IS 40

A box of chocolates contains milk chocolates and dark chocolates in the ratio 4:3
The box contains 35 chocolates
how many milk chocolates are there in the box?

Answers

Answer:

20 milk chocolates

Step-by-step explanation:

The first step is adding together 4 + 3. You will get 7. This is the total number of units in the box.

Then, divide 35 by 7. You will get 5 as the answer.

To find the number of milk chocolates, multiply 5 and 4. You will get 20 as the answer.

4x+3x=35
7x=35
x=5

milk chocolate 4(5) = 20
dark chocolate 3(5) = 15

y is inversely proportional to x.when y=7 x=9 a) work out an equation connecting y and x b) work out the value of y when x=21

Answers

Answer:

a) y = k/x

7 = k/9

b) y = 3

Step-by-step explanation:

From the question, we are told that:

y is inversely proportional to x.

Mathematically:

y ∝ 1/x

y = k × 1/x

y = k/x

k = Constant of Proportionality

a) work out an equation connecting y and x

To find this Equation,

y = k/x

when y=7 x=9

Hence:

7 = k/9

b) work out the value of y when x=21

We find the value of k first

7 = k/9

k = 7 × 9

k = 63

Hence, the value of y when x=21

y = k/x

k = 63, x = 21

y = 63/21

y = 3
