Answer:

72

Step-by-step explanation:

<u>Cost of each item:</u>

Pizza = $1.50, Hotdogs = $1.25

<u>Number of each item:</u>

Pizza = x, Hotdogs = x + 20

<u>Total cost:</u>

1.25x + 1.5(x + 20) = 173
1.25x + 1.5x + 30 = 173
2.75x = 143
x = 143/2.75
x = 52

<u>Number of slices of pizza:</u>

52 + 20 = 72

Little Snail is going to visit his friend over at the next pond, 3 miles away. He can crawl ( 1/2. 1/3, 1/4, 3/4, 2/3 ) of a mil

KIM [24]

Solution :

It is given that Little Snail is going to visit one of his friend at the pond which is 3 miles away.

When the snail crawls 1/2 of a mile per day, it will take him, $1 \times \frac{2}{1} \times 3$

= 6 days to get to the next pond.

When the snail crawls 1/3 of a mile per day, it will take him, $1 \times \frac{3}{1} \times 3$

= 9 days to get to the next pond.

When the snail crawls 1/4 of a mile per day, it will take him, $1 \times \frac{4}{1} \times 3$

= 12 days to get to the next pond.

When the snail crawls 3/4 of a mile per day, it will take him, $1 \times \frac{4}{3} \times 3$

= 4 days to get to the next pond.

When the snail crawls 2/3 of a mile per day, it will take him, $1 \times \frac{3}{2} \times 3$

= 4.5 days to get to the next pond.

Myra is evaluating the expression –31. 7 4. 5x, when x = 2. 1. -31. 7 4. 5(2. 1) –27. 2(2. 1) –57. 12 What was Myra’s error? Myr

This is just an algebraic problem, the correct option is:

<em>"Myra should have multiplied 4.5 and 2.1 first."</em>

<h3>How to evaluate an expression?</h3>

Here we want to evaluate the expression:

-31.7 + 4.5*x

in x = 2.1

This just means that we need to replace x by 2.1 in the given equation.

Now, what Myra does is:

-31.7 + 4.5*2.1 = -27.2*2.1

So she took the sum between -31.7 and 4.5 first, this is her mistake, you only would do that if the expression was:

(-31.7 + 4.5)*2.1

But in our expression:

-31.7 + 4.5*2.1

The first thing you need to solve is the product in the second term, so we get:

-31.7 + 4.5*2.1 = -31.7 + 9.45 = -22.25
