erica earn money by tutoring and babysitting. She always tutors for 5 hours each week and the amount she babysits changes from week to week. let x be the hours that arica babysitters. Write an expression to show the total numbers of hours erica works each week.

Numbers That you have to use to solve this problem: +,-, . , =, ( , ), x, 5, 8, 13.

Answers

5+8=13 I don’t really know but I mean I tried

The expression to show the total number of hours erica works each week is 5 + x.

What are work and time?

Work is the completion of any task for example if you have done your homework in 5 hours then you have done 5 hours.

Another example of work is that if you have done your food by 1 hour it means your work duration is 1 hour so work is basically the time duration of any task which you have done.

Given that Arica earns money by tutoring and she did by 5 hours each week and she also babysits for x hours each week.

Hence, 5 + x will be the correct expression to show the total number of hours erica works each week.

So erica earns money of a total of that 5 + x of the week the value of x is anything it could be 1 ,2 anything.

Select all the expressions that are equivalent to –8.
A)80100
B)–800100
C)80 ÷ (–10)
D)–80 ÷ (–10)
E)−80−100

Answers

Answer:

The only one I can see right now is (C)

Step-by-step explanation:

Because a positive divided by a negative is negative, so 80/-10 is -8.

For A and B the numbers dont seem to make sense, are there any equations in middle of the numbers? I can help in comments if you tell me.

The expressions that are equivalent to –8 is only option C i. e 80 ÷ (–10)

What is Expression?

Expression is a combination of operators, variables and numbers

Two expressions are said to be equivalent when we solve both we get the same answer.

For A and B the numbers dont seem to make sense, are there any equations in middle of the numbers

For option C, –8 is equivalent to 80/-10 because a positive divided by a negative is negative, so 80/-10 is -8.

For option D, –8 is not equivalent to -80/-10 because a positive divided by a positive is positive, so -80/-10 is 8.

So option C is equivalent to -8.

Ashley has a total of $35 to spend at the carnival this year. She wants to purchase a turkey leg for $12, also. If each ride costs $0.50, how many rides can Ashley get on? IDENTIFY THE CONSTANT.

Answers

Answer:

46 rides; the constant is the $12 turkey leg

Step-by-step explanation:

To solve this, you can write an equation:

c = .5r + 12

where c is cost and r is rides (the constant is 12 because it doesn't change)

You already know that the cost is 35, so you just need to plug it in and solve:

c = .5r + 12; c = 35

35 = .5r + 12

23 = .5r

r = 46

So, on $35 and an expense of $12, Ashley can ride 46 rides.

Answer:

Ashley can go on 46 rides

Step-by-step explanation:

12+0.50x=35

-12               -12

0.50x=23

0.50x/0.50= 23/0.50

 x=46
