1. Are there more inches in a mile or second in a day?​

Answer:

m∠XAZ = 40°

Step-by-step explanation:

Since ∠YAU, ∠YAZ and ∠XAZ are the angles based at a point on a straight line, and the sum of the all angles on a line is 180°.

Therefore, m∠YAU + m∠YAZ + m∠XAZ = 180°

50° + 90° + m∠XAZ = 180°

m∠XAZ = 180° - 140°

             = 40°

Therefore, measure of angle XAZ is 40°.

Answer:

1/3x+3

It is asking for 1/3 of x which is 1/3x

three more essentially means add 3

So 1/3x+3 is the answer

The expression is,

y = 1/3x+3

Where, y is number write with the help of x

And, x is a number.

Here,

We have to write an expression for a number that is three more than one third the value of x.

What is Number system?

A system of writing to express the number is called Number system.

Now,

x represents a number.

Let a number y which is written as, three more than one third the value of x.

One third of x = 1/3 x

Then, more than 3 means to add 3, we get

y = 1/3 x + 3

Hence, The expression is,

y = 1/3x+3

Where, y is number write with the help of x

And, x is a number.

Given

7(x + 1) = 21 ( divide both sides by 7 )

x + 1 = 3 ( subtract 1 from both sides )

x = 2

Answer:

x=2

Step-by-step explanation:

7×(x +1)=21

7x +7 =21

7x =21 - 7

7x =14

Answer:

x= 11

Step-by-step explanation:

[tex]3x - 5 = \frac{12 + 4x}{2} [/tex]

Multiply both sides by 2:

2(3x -5)= 12 +4x

Expand:

2(3x) +2(-5)= 12 +4x

6x -10= 12 +4x

Bring all x terms to 1 side, constant to the other:

6x -4x= 10 +12

2x= 22

Divide by 2 on both sides:

x= 22 ÷2

x= 11

Answer:

Step-by-step explanation:

Her rate (speed) is

v = d/t = (792 miles) / (11 hrs) = 72 mph

To drive a distance D = 504 miles, it will take her a time T given by

T = D/v = (504 miles) / (72 mph) = 7 hours

Answer:

n= 98/3

Step-by-step explanation:

1. Complete distributive property *5(n-14)* and *2(n+14)*

5n-70=2n+28

2. Subtract 5n from both sides

-70=-3n+28

3. Subtract -70 from both sides

-98=-3n

4. Divide the variable from both sides *-3n*

-98/-3

5. Simplify

98/3

Final Answer:

98/3

Answer: 7

Step-by-step explanation: First you subtract 5 from both sides to single out the -3x. Then you will have -3x = -21. You will then divide both sides by negative three because you want to single out the x. After that, you will have the answer of x = 7

Answer:

x = 7

Step-by-step explanation:

-3x+5=-16

    -5  -5

-3x=-21

-3x/3 = -21/-3

x=7

Given :

Ben's age x is 3 times his age 12 years ago.

To Find :

The  current age of Ben.

Solution :

It is given that current age of Ben is x.

So, his age 12 years ago is (x - 12).

Expressing given condition mathematically , we get :

[tex]x=3(x-12)\\\\x=3x-36\\\\2x=36\\\\x=18\ years[/tex]

Therefore, current age of Ben is 18 years.

Hence, this is the required solution.

Answer:

t = [tex]\frac{l}{pr}[/tex]

Step-by-step explanation:

Formula or literal equation used to calculate the simple interest is,

l = prt

where 'l' = Simple interest

p = principle amount invested

r = rate of interest

t = time or duration of the investment

If we have to calculate the time of investment form the given formula,

l = prt

By the division property of equality,

[tex]\frac{l}{pr}=\frac{prt}{pr}[/tex]

[tex]t=\frac{l}{pr}[/tex]

Therefore, formula to be used is, [tex]t=\frac{l}{pr}[/tex]
