Lizzy bought 4 bags of apples at the store. Her mom gave her 8 more apples. Now Lizzy has 36 apples. How many apples were in each bag?

Answers

Answer 1

Answer: 36 - 8 = 28
Lizzy bought a total of 18 apples from the store.
28/4=7
There are 7 apples in each bag.

Answer 2

Answer: 4b+8=36
Subtract 8 from both sides
4b=28
Divide by 4 on both sides to get b by itself
b=7

7 apples were in each bag

A ceramic artist can shape a pot in 3 minutes. It takes 10 minutes to fire one batch of pots in the kiln. If there are p pots in a batch, which expression represents the time it takes to shape and fire one batch of pots? How long will it take the potter to form and fire a batch of 10 pots? A.The expression is 3p. It takes 30 minutes to shape and fire 10 pots.B.The expression is 3p − 10. It takes 20 minutes to shape and fire 10 pots.

C.The expression is 3(p + 10). It takes 60 minutes to shape and fire 10 pots.

D.The expression is 3p + 10. It takes 40 minutes to shape and fire 10 pots.

Answers

Answer:

D. The expression is $3p+10$ . It takes 40 minutes to shape and fire 10 pots.

Step-by-step explanation:

Let the number of pots in a batch = p

Now, one pot takes 3 minutes to get in a shape.

Then, 'p' pots will take $3p$ minutes to get in a shape.

Also, it takes 10 minutes to fire one batch of pots.

Thus, the expression for the time taken to form one batch of pots = $3p+10$

So, when number of pots = 10 i.e. p= 10.

Time taken to fire the pots = $3* 10+10$ = 30+10 = 40

That is, 'It takes 40 minutes to shape and fire 10 pots'.

Thus, option D is correct.

3p to shape and 10 minutes to fire
= 3p + 10
3x10 + 10 = 40 minutes for a batch of 10 pots
therefore D is the correct answer

Round 118.380 to the nearest hundredths

Answers

The number in the hundredths place is 3, so look to the number at the right of 3. If it is equal to or above 5, you would have to round the number in the hundredths place to one number higher. Because 8 is above 5, you would round 3 to 4.

118.380 rounded to 118.4 is your answer

Hope this helps :)

A pilot takes a taxi from the airport to the hotel. The taxi driver charges a $2.50 initial charge plus $2.65 per mile. Which equation can be used to find y, the total cost of the trip, if x represents the number of miles of the trip?a y = 2.65(x + 2.50)
b y = 2.65x-2.50
c y = 2.50x+2.65
d y = 2.65x+2.50

Answers

Answer:

d y=2.65x+2.50

Step-by-step explanation:

The correct answer would be d because y is the total cost with a start value of 2.50 and a slope of 2.65x. Then you would just replace the equation y=mx+b with these values

the correct answer is d
