the unit digit of a 2 digit number is 5 more than the tens diget and the number itself is 3 times the sum of the digits. find the NUM

Answers

Answer 1

Answer:

27

Step-by-step explanation:

Let the tenth digit is x and units digit is y.

We have the following equations:

y = x + 5(x + y)*3 = 10x + y

Simplify the second equation:

3x + 3y = 10x + y2y = 7x

Solve by substitution:

2(x + 5) = 7x2x + 10 = 7x7x - 2x = 105x = 10x = 2

Find y:

y = 2 + 5y = 7

The number is 27

Answer 2

Here the equations are if the digits be a and b

b=a+5--(1)

3(a+b)=10a+b

3a+3b=10a+b7a=2bb=7/2a--(2)

Equate both

7a/2=a+5

7a=2a+105a=10a=2

And

b=2+5=7

The number is 27

An after-school daycare program must have 1 counselor for every 15 children. The program must also have 1 director. There are 8 employees with the daycare program. At most, how many children are there?

Answers

Answer:

105 children

Step-by-step explanation:

15x7 because the last 1 is the director of the program. and since there are y employees that are acting as counselors, the answer would be 105 children.

I think the answer is 105

Please correct in comments if I am wrong.

All you have to do is times 7 by 15 because it never said there had to be any children for the director.

There has to be 1 counselor every 15 children. You have to do 8 minus one times 15 and you would get 105.

How do i do this?

pls put explanation

Answers

Answer:

1. 15

2. 3

Step-by-step explanation:

These are functions of functions. You always solve the inner function first.

For number 1, the inner function is g(1) so you plug in 1 for the g function. g(1)=1+4 = 5

Since g(1)=5, you can replace g(1) with 5. Now you have f(5).

Plug in 5 for the function of f.

f(5)=3(5)=15.

For Number 2, it is the same steps but with different numbers and functions. h(0)=(0)²-1 = -1

g(-1)=-1+4=3

Please note that if the "hanger" is cut off the following is not true,

a. 11 = 10x

     This is showing that 11 is equal to whatever is on the other side since the "hanger" is level. Think of it as a scale (picture attached, the image is from https://antiques.lovetoknow.com/antique-balance-scales).

     We know that one side of the equation will be equal to 11. The other side will be 2x multiplied by 5 because there are five "2x" parts. 5 * 2 = 10, so 5 * 2x = 10x

b. x = 1.1

11 = 10x

10x = 11

x = [tex]\frac{11}{10}[/tex]

x = 1.1

Write an inequality that represents the phrase. Then show the solution to the inequality.

The sum of 1 and x is less than 5

Answers

Answer:

The original inequality is 1+x < 5

That inequality solves to x < 4

================================================

Explanation:

The term "sum" means "result of addition". For example, the sum of 3 and 7 is 3+7 = 10.

In this problem, the sum of 1 and x is 1+x. We don't know what x is, so we can't combine it with the 1. We leave it as is.

The expression 1+x is less than 5, meaning we write 1+x < 5

To solve this, we subtract 1 from both sides

1+x < 5

1+x-1 < 5-5

x < 4 is what happens when you isolate x.

This describes any number smaller than 4.

Inequality that represents the phrase:
1 + x < 5

To solve:
Subtract 1 from both sides.
Your solution to the inequality is x<4
