Write a numerical expression to represent the following: Margot took $45 with her to the amusement park. She spent $20 on lunch and spent $5 to rent an inner tube. Then find the sum.
45 + (–20) + (–5); 15
45 + (–20) + 5; 30
(–45) + (–20) + (–5); –70
45 + (–20) + (–5); 20
4. Compare the integer statements. Use >, <, or = to complete the statement.
(–10)+ 2 ⎕ (–2)+ 10
(–10) + 2 < (–2) + 10
(–10) + 2 > (–2) + 10
(–10) + 2 = (–2) + 10
(–10) + 2 ≥ (–2) + 10
To represent the situation where Margot took $45 with her to the amusement park, spent $20 on lunch, and spent $5 to rent an inner tube, we can use the numerical expression 45 + (-20) + (-5).
Now, let's find the sum:
45 + (-20) + (-5) = 45 - 20 - 5 = 15
So the sum is 15.
For the next question, we have the expressions (-10) + 2 and (-2) + 10.
To compare these expressions, we can simply evaluate them and then compare the results.
(-10) + 2 = -8
(-2) + 10 = 8
Now, we can compare the results:
-8 < 8
Therefore, the correct comparison using the symbols >, <, or = is:
(-10) + 2 < (-2) + 10
