Answer:

2x+4=60

Step-by-step explanation:

let X represent Danny's age.

and X+4 represent Levar's age since he's 4 years older than Danny we add 4.

subtract 4 from both sides and then divide by 2 and Danny's age is 28 and Levar is 32

Answer:

0.8

Step-by-step explanation:

"percent" means "per 100" which is the same as "divide by 100."

To change a percent to a decimal, divide the percent by 100.

80% = 80/100 = 0.8

Step-by-step explanation:

Answer:

Step-by-step explanation:

If an elephant charged 13.3 meters in 15 seconds, to calculate the distance charged by the elephant in one minute, the following steps will be arried out.

15 seconds = 13.3 meters

1minute (60 seconds) = x

cross multiply

15 * x = 13.3 * 60

15x = 798

Divide both sides by 15

15x/15 = 798/15

x = 53.2metres

Hence the elephant will charge 53.2 meters for 1 minute

Answer:

B

Step-by-step explanation:

So we want to find the value of x.

Note that the entire segment (JK) is the sum of the segments JI and IK. In other words:

[tex]JK=JI+IK[/tex]

We know that JK is (2x-1), JI is (2), and IK is (x+3). Substitute:

[tex]2x-1=(2)+(x+3)[/tex]

On the right, add:

[tex]2x-1=x+5[/tex]

Add 1 to both sides:

[tex]2x=x+6[/tex]

Subtract x from both sides. The right cancels:

[tex]x=6[/tex]

And the value of x is 6.

Our answer is B.

Answer:

See below.

Step-by-step explanation:

H.

f = 3x + 31

c = 12x - 1

3x + 31 + 12x - 1 = 180

15x + 30 = 180

15x = 150

x = 10

same-side interior, supplementary

R.

b = x - 10

g = 4x + 60

x - 10 + 4x + 60 = 180

5x + 50 = 180

5x = 130

x = 26

same-side exterior, supplementary

E.

d = 2x + 13

e = 7x + 5

2x + 13 + 7x + 5 = 180

9x + 18 = 180

9x = 162

x = 18

same-side interior, supplementary

I.

a = 10x - 30

e = 8x + 20

10x - 30 = 8x + 20

2x = 50

x = 25

corresponding, congruent

G.

b = x + 30

h = 5x - 14

5x - 14 = x + 30

4x = 44

x = 11

alternate exterior, congruent

Answer:

60000

Step-by-step explanation:

Answer:

60,000

Step-by-step explanation:

2 times 30,000 is 60,000

Answer:

Yes, that is true, and x=45.

Step-by-step explanation:

Yes, that's how you set up the equation I also listed the sets to solve it below:

3x+15=2x+60

-2x.     -2x

--------------------

x+15=60

  -15 -15

------------------

x=45

You can also plug it in to check your work.

3(45)+15=2(45)+60

135+15=90+60

150=150

Step-by-step explanation:

Answer:

A. -5 - 3x > 10

Step-by-step explanation:

x = -6

A. -5 - 3(-6) > 10

-5 + 18 = 13 > 10

true

B. -3 - 5(-6) < -14

-3 + 30 = 27 < -14

false

C. 1 - 2(-6) > 13

1 + 12 = 13 > 13

false

D. 2 - (-6) <-3

2 + 6 = 8 < -3

false
