Answer:
110
Step-by-step explanation:
What is the Difference between -45 and +65? In other words, what is the Difference between negative 45 and positive 65?
To solve this math problem, start by picturing a horizontal number line that starts with negative infinity on the left and ends with positive infinity on the right:
∞ ..... -3, -2, -1, 0, +1, +2, +3, .... ∞
The Difference between -45 and +65 is the distance between -45 and +65 on our number line above. Thus, the Difference between two numbers will always be a positive number.
It is a two-step process to calculate the Difference between -45 and +65. Step 1 is to subtract +65 from -45, and Step 2 is to find the absolute value of the Step 1 answer. Here is the math to illustrate better:
(-45) - (+65) = -110
|-110| = 110
That's it! The Difference between -45 and +65 is as follows:
110
Kendra is going faster. You could convert Kendra's measurement to feet per second by doing to following:
0.25 mi/1 min x 5280 ft/1 mi x 1 min/60 sec
Which equals:
(0.25)(5280)ft/60 sec
Simplify, and Kendra's speed is 22 feet per second.
mi= mile(s)
min= minute(s)
ft= feet
sec= second(s)
The y-intercept is (0,7) and the x-intercept is (-2,0).
