Step-by-step explanation:

Half a number increased by 4 is the same as six less than that number

Answers

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

1. Henry is using a total of 40 ft. of lumber to make a bookcase. The left and right sides of the bookcase are each 8 ft. high. The top, bottom, and two shelves are all the same length, labeled .

Part A: Construct an equation to model the situation. (5 points)




Part B: Solve the equation. Show all your steps.

(5 points)





Part C: Use the solution to answer the question in a complete sentence. (5 points)

Answers

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

Help Needed!! Find The Measure Of Angle A In The Triangle

Answers

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:

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

470470 milliliters each.
How many milliliters of blood did the volunteers donate?

Answers

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.

Answers

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

Answers

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.
