Answer: 6 1/5 miles
Step-by-step explanation:
Here's the complete question:
On Tuesday, Stacy rode her bicycle 1 3/4 miles from her house to the supermarket. She walked 1/4 of a mile while at the supermarket. She rode her bicycle a different way home that was 2 1/5 miles long. How many miles did Stacy ride her bicycle on Tuesday.
The number of miles that Stacy ride her bicycle on Tuesday will be the addition of her distance from her house to the supermarket and back to her house from the supermarket. This will be:
= Distance to supermarket = 1¾ + ¼ = 2 miles
Distance from supermarket = 2 + 2 1/5 = 4 1/5 miles
Total distance = 2 + 4 1/5 = 6 1/5 miles

the first answer option
Step-by-step explanation:
|x + 4| = 2
so,
(x + 4) must be +2 or -2 to make the original equation true.
when is (x + 4) = 2 ?
x + 4 = 2
x = -2
when is (x + 4) = -2 ?
x + 4 = -2
x = -6
so, -6 and -2 are the correct solutions.
