Brian bought 4 yards of fabric. How much is this in feet?

Answer:

20:25

Step-by-step explanation:

To find an equivilant Ratio is very simple. You only need to multiply both numbers by the same number. FOr example 3:6. To find an equivilant ratio for that you can multiply 3 by 4 and 6 by 4 to get 12:24 or 1:2

Hope this helps!

Answer:

Inverse Proportion

Step-by-step explanation:

As x increases, y decreases. so. inverse proportion

Answer:

Part A:

40 = 16 + 4·s

Part B:

The length of the top and bottom and the two shelves are each = 6 ft.

Part C:

The width of the bookshelf is 6 feet

Step-by-step explanation:

The given parameters are;

The length of the lumber Henry is using to make the book case = 40 ft.

The height of the left and right side of the book case = 8 ft. each

The length of the top and bottom and the two shelves are each = s

Therefore, we have;

Part A:

The equation is given as follows;

40 = 8 × 2 + 4·s = 16 + 4·s

40 = 16 + 4·s

Part B:

The solution of the equation is given as follows;

40 = 16 + 4·s

4·s= 40 - 16 = 24

s = 24/4 = 6 ft.

s = 6 ft.

The length of the top and bottom and the two shelves are each = 6 ft.

Part C:

The width of the bookshelf is 6 feet

Answer:

x=43

Step-by-step explanation:

Subtract 61 from both sides giving:

x=43

Answer: x=43

Step-by-step explanation:

subtract 61 on both sides to isolate the variable. Divide 1x by 43 to get 43

Answer:

the number is 20

Step-by-step explanation:

Denote the number as "x",

write out the problem:

(1/2(x)) + 4 = x - 6

inverse operations

(1/2(x)) + 4 = x - 6

           +6        +6

(1/2(x)) + 10 = x

-(1/2(x))           -(1/2(x))

10 = ((1/2)x)

*2       *2

20 = x

Answer:

470(32 - n)

Step-by-step explanation:

Here are the given:

> 32 volunteers

> n volunteers who didn't donate

> 470 mL each

So your expression is: 470(32 - n).

Why?

Subtract the 32 volunteers who want to donate blood from the volunteers who were not able to donate then multiply it by 470.

17. True (bc anything multiplied by 0 equals 0)

18. True (bc 13=13)

19. True (bc 6=6)

20. True (bc 7(x-3)=7x-21)

21. True (bc the negative sign cancels out the positive sign)

22. True (bc y=3 and 3=y are the same)

23. True (bc they are the same just rearranged)

24. True (because x and z both equal -1)

25. True (anything multiplied by 1 stays the same)

Answer:

8. x=18  9. x=33   10. x=65  11. x=19  12. x=59

Step-by-step explanation:

8.  The angles are essentially vertical so they have to be equal to each other.

42=2x+6   subtract 6 from both sides  36=2x   x=18

9.  These angles are supplementary and equal 180 when added together.

98+(3x-17)=180  subtract 98 and add 17 to both sides  3x=99  x=33

10.  Angles are essentially vertical so they are equal to each other.

2x+2=3x-63  add 63 to both sides subtract 2x from both sides  65=1x

11.  Angles are supplementary so they equal 180 when added together.

112+(4x-8)=180 subtract 112 and add 8 to both sides   4x=76   x=19

12.  Angles are vertical so they are equal to each other.

(3x-33)=(2x+26)  add 33 to both sides and subtract 2x   59=1x

Answer:

the answer is b

Answer:

-9/4 or -2 1/4 (it is the same amount)

Step-by-step explanation:

Answer:

A=40°

Step-by-step explanation:

All angles in a triangle add up to 180°, so we take 60 away from 180 because we know that angle.

180-60=120

Next, we add up the number of x,

10x+20x=30x

Third, we need to find out what x is, so we divide 120 by 30, which gives us 4.

x=4

to find out what 10x is (A), we multiply 4 by 10

4×10=40

A=40

Answer: y = 0.5x - 10

Step-by-step explanation:

2x + y = -4

y = -2x - 4

perpendicular, so slope = 1/2

y + 6 = (1/2)(x - 8)

y = (1/2)x - 10

Answer:

Tenley will use _9_ feet of wood.

Step-by-step explanation:

The key here is to multiply 4 by 2.25. If just adding 2.25 4 times is easier, go for that. Either way the correct answer will be 9 feet.
