Jack's father is 3 times older than jack. 5 years ago the sum of their ages was 34. How old is jack now?
PLS HELP ASAP!!!

Answers

Answer 1

Answer:

jack (with the lower case j) is 11 years old

Step-by-step explanation:

(x - 5) + (3x - 5) = 34

x - 5 + 3x - 5 = 34

4x = 34 + 10

4x = 44

x = 11

So, jack = 11 years old.

Jack = 33 years old.

Answer 2

Answer:

the answer is 16

Step-by-step explanation:

Lacy = x

Jack = 3x

(x - 5) + (3x - 5) = 34

x - 5 + 3x - 5 = 34

4x = 34 + 10

 

4x = 44

x = 11

So, Lacy = 11 years old.

Jack = 33 years old.

There no answer because there is a variable next to a number that is being added and you can’t split them

Because there is no sum we can’t find the variable (what R equals) so the answer can only be two things if you are factoring the equation the answer would be 2(R+4). If you are trying to simplify it would remain R2+8.

How can you isolate the variable in this inequality?

3b < -99.

A
Subtract 99 from 3b.

B
Add 99 to both sides.

C
Divide both sides by 3.

D
Multiply both sides by 3.

Answers

Answer:

C- Divide both sides by 3.

Step-by-step explanation:

In order to isolate the variable, we will have to remove all non-1 coefficients from the variable. Since 3b can be written as 3(b), b is being multiplied by 3. So the only way to isolate the variable is to do inverse operations, which would be to divide both sides of the inequality by 3.

At a cookout, Mrs. Crawford makes 8/9 pound of chicken, plus 1 pound for each guest. Is the relationship between the number of guests and pounds of chicken proportional? Explain.

Answers

Answer:

No, this rel. is not proportional because of the addition involved ("plus 1 lb for each guest").

A proportional rel. features mult. only.

Step-by-step explanation:

et x represents the number of guest and y represents the number of pounds of chicken made,

Given,

The number of pounds of chicken for each guest = 1,

So, the number of pounds for x guests = x,

Also, the number of pounds already made =

Thus, the total pounds of chicken,

Since, a relation is called proportional if the variables are directly proportional,

That is, the line obtained by the relation passes through the origin,

Since, if x = 0, y = 0,

∴ Line  does not pass through the origin.

No, it is not a proportional relation. Thus, the total pounds of chicken, ... Hence, given relation is not proportional.

-1/3, -1/5, 0, 1/8
u put the negative numbers to the left and positive ones to the right then since -1/3 is more negative than -1/5, -1/3 goes to the left and-1/5 goes next to it and then 0 and since 1/8 is the biggest it goes to the right
Since it’s negative the negative is the least but there two of them so you have to convert them to decimales
1/3 = .333333 and 1/5 is .2
So 1/3 goes first then 1/5
1/8 is .125 it’s larger than 0
