The sum of a number and seven more than the number is 43. What is the number?

Answers

Answer:

18

Step-by-step explanation:

we can use the variable x to represent the number since it's currently unknownseven more than the number can be represented as x + 7we can find the sum of both by adding them

x + x + 7 = 43

2x + 7 = 43

     -7     -7

2x = 36

we divide by 2 on both sides to isolate x

x = 18

a man is 3 times as old as his son. the sum of their ages is 48 years, how old is the son?

Answers

Let the sons age = x

The dads age would be 3x ( 3 times the sons age)

X + 3x = 48

Simplify:

4x = 48

Divide both sides by 4

X = 12

The sons age is 12

Evaluate 1/2(x divided by 4)+y when x = 16 and y = 2/5 A. 4/5, B. 19/10, C. 12/5, D. 32/5

Answers

The expression 1/2(x divided by 4)+y when evaluated for x = 16 and y = 2/5 is 12/5

How to evaluate the expression

The mathematical statement of the expression is given as

1/2(x divided by 4)+y

When the above expression is expressed using proper mathematical operators

We have the followng expression

1/2(x/4) + y

From the question, we have the followng values

x = 16 and y = 2/5

This means that

1/2(x/4) + y = 1/2(16/4) + 2/5

When evaluated, we have

1/2(x/4) + y = 12/5 or 2.4

Hence, the value of the expression si 12/5

Ola taxi charges a $8 flat rate in addition to $2 per mile. Paul has no more than $10 to spend on a ride.

2)

Let x be the number of miles.

Then, we have inequality: 8x+2<=10

Solve the inequality: 8x+2<=10

Subtract 2 from both the sides:

8x+2-2<=10-2

Simplify

8x<=8

Divide by 8 both sides we get

x<=1;
