Answer 1

Answer:

1. y=4

y=x+7

4=x+7

x= -3 , y= 4

2. y=3x

y=x+5

3x=x+5

2x=5

x=5/2 or 2.5

y= 3(5/2)

y= 15/2 or 7.5

x= 2.5, 7= 7.5

Answer 2

Answer:

1. x= -3           2. x= 5/2

Step-by-step explanation:

You need to substitute the second y equation given into the first one to find x. Then get x by itself on one side.

1. 4= x + 7

  -7       -7

  -3 = x

  x= -3

2. 3x= x + 5

   -x    -x

   2x= 5

  (2x= 5) /2

   x= 5/2

Jerry built a 2 inch cube to hold his marble collection. He wants to build a cube with a volume 8 times larger. How much will each edge measure?

Answers

Answer:

4 inches

Step-by-step explanation:

Jerry built a 2 inch cube to hold his marble collection.

Volume of this cube = 2³ = 8 cubic inches

He wants to build a cube with a volume 8 times larger.

Hence: 8 × 8 in³ = 64 in³

The measurement of each edge is calculated as:

√64 in³ = 4 inches

Step-by-step explanation:

Let us find component of these forces in x and y direction.

The solution along with diagram can be found in attachment.

We have found resultant in X- direction = 6√3 N

resultant in Y- direction = 2 N

therefore net force resultant force = [tex]\sqrt{(6\sqrt3)^2+2^2}[/tex]

Find the value of x. Round to the nearest tenth.

Answers

Answer:

1) x = 20. 8

2) x = 42.3

3) x = 13.0

4) x = 42.1

Step-by-step explanation:

1) Use Sine

(Sine = [tex]\frac{opposite}{hypothenuse}[/tex]) Sine 53 = [tex]\frac{x}{26}[/tex]

(sine of 53 is 0.80) 0.80 = [tex]\frac{x}{26}[/tex]

(multiply 26 on both sides) 0.80 x 26 = [tex]\frac{x}{26}[/tex] x 26

(solve) 20.8 = x

2) Use Tan

(Tan = [tex]\frac{opposite}{adjacent}[/tex]) Tan 78 = [tex]\frac{x}{9}[/tex]

(tan of 78 is 4.70) 4.70 =  [tex]\frac{x}{9}[/tex]

(multiply 9 on both sides) 4.70 x 9 =  [tex]\frac{x}{9}[/tex] x 9

(solve) 42.3 = x

3) Use Cosine

(Cosine = [tex]\frac{adjacent} {hypothenuse}[/tex]) Cos 22 = [tex]\frac{14}{x}[/tex]

(cos of 22 is 0.93) 0.93 = [tex]\frac{14}{x}[/tex]

(multiply 14 on both sides) 0.93 x 14 = [tex]\frac{14}{x}[/tex] x 14

(solve) 13.02 = x

(round to the nearest tenth) 13.02 = 13.0

4) Use tan

(Tan = [tex]\frac{opposite}{adjacent}[/tex]) Tan 39 = [tex]\frac{52}{x}[/tex]

(tan of 39 is 0.809) 0.809 = [tex]\frac{52}{x}[/tex]

(multiply 52 on both sides) 0.809 x 52 = [tex]\frac{52}{x}[/tex] x 52

(solve) 42.068 = x

(round to the nearest tenth) 42.068 = 42.1

Solve. 20/n+10 = 10/n+20 n = -10 n = -20 n = 30 n = -30

Answers

Answer:

20/n+10 = 10/n+20 n

multiply both side n,

n (20/n+10) = n(10/n+20 n)

20+10n = 10+20n^2

20+10n -20 = 10+20n^2 -20

10n  = 20n^2 -10

10n  - 10n  = 20n^2 -10 -10n

0 = = 20n^2 -10 -10n

20n^2 -10 -10n = 0

n = 1 or n = -0.5
