Jordan is mixing water and flour to make tortillas. The
number of cups of water, w, needed for f cups of flour
is described by the equation w= = 0.75f
How many cups of water are needed to mix with 4 cups
of flour?
Please help!!!

Answers

Answer:

w = 3 cups when f = 4 cups

Step-by-step explanation:

Given:

w = 0.75f

Where,

w = number of cups of water

f = number of cups of flour

Find w when f = 4 cups

w = 0.75f

Substitute f = 4 into the equation

= 0.75(4)

= 3

w = 3 cups when f = 4 cups

suppose 4<a<7. find all the possible values of 15-2a

Answers

9514 1404 393

Answer:

1 < 15 -2a < 7

Step-by-step explanation:

There are a couple of ways you can do this.

1) Put the minimum and maximum values of a into the expression to see what its corresponding values are:

15-2a for a=4:

15-2(4) = 7

15-2a for a=7:

15-2(7) = 1

Then ...

1 < 15-2a < 7

2) Solve for a in terms of the value of 15-2a, then impose the limits on a.

x = 15 -2a

2a = 15 -x

a = (15 -x)/2

Now, impose the given limits:

4 < (15 -x)/2 < 7

8 < 15 -x < 14 . . . multiply by 2

-7 < -x < -1 . . . . . . subtract 15

7 > x > 1 . . . . . . . . multiply by -1

1 < 15-2a < 7 . . . . . use x=15-2a

_____

The vertical extent of the attached graph is the range of possible values of 15-2a. It goes from 1 to 7.

Answers

Answer:

x = 4

Step-by-step explanation:

A:3(x+2)=18

Divide each side by 3

3/3(x+2)=18/3

x+2 = 6

This is the same equation as equation B

They will have the same solution since they are the same equation

x+2-2 = 6-2

x = 4

tall, how many folders can you fit into this cabinet? (Draw a picture!)

Can two people with blue eyes have a child with brown eyes? Why or why not? also i really don´t really know the subject so i put it in math.

Answers

Answer:

Yes

Step-by-step explanation:

In the family the blue eyed people may have had a gene with brown eyes. So if both parents carry that gene even if they don't display it, it can be still shown because brown eyes are the most dominant trait.

BR Elder 1: BL BR BL Elder 2: BL BL BL Elder 1: BL BL BL Elder 2: BR BL

I I I I

I I

Parent 1: Blue gene brown gene Parent 2: Blue gene brown gene

Child Brown eyes: BR BL

Because the brown gene is dominant if the gene shows up in both parents the child would be more likely to have brown eyes than blue.

I have 5 digits. My q is worth q * 10,000. My 2 is worth 2 thousand. One of my 7s is worth 70. The other is worth 10 times as much. My other digit is a 6. What number am l

Answers

Answer:

92,776

Step-by-step explanation:

I have 5 digits. My 9 is worth 9*10,000. My 2 is worth 2 thousand. One of my 7s is worth 70. The other is worth 10 times as much. My other digit is a 6. What number am I?

My 9 is worth 9*10,000 = 9 * 10,000

= 90,000

My 2 is worth 2 thousand = 2,000

One of my 7s is worth 70 = 70

The other is worth 10 times as much = 70 * 10

= 700

My other digit is a 6 = 6

The number is

90,000 + 2,000 + 700 + 70 + 6

= 92,776
