Answer:
Associative Property of Addition
Step-by-step explanation:
From the list of given options, option A correctly answers the question and this is because
--- (1)
or
--- (2)
<em>The above illustrations only apply to Associative Property of Addition</em>
In Crystal's case:

This can be compared to (1) above
Hence;
<em>Option A answers the question</em>
Y = x + 5....so we sub in x + 5 for y in the other equation
4x + y = 20
4x + x + 5 = 20
5x + 5 = 20
5x = 20 - 5
5x = 15
x = 15/5
x = 3
y = x + 5
y = 3 + 5
y = 8
solution is (3,8)
The expression that represents her weekly income is:
180 + 0.03w
Answer:
y = x
Step-by-step explanation:
We can use slope-point form.
(y-y1) = m(x-x1)
m is a slope. If the line is parallel than slopes are the same.
y = x + 4, for this line slope = 1, so for line we have to find slope is also 1.
(y-y1) = m(x-x1)
m=1, x1 = 2, y1 = 2
(y - 2) = 1(x-2)
y - 2 = x - 2
y = x
1.the flight from Baltimore to Miami is 2 hours and 35 minutes
2.the flight to Boston from Baltimore is the shortest.
Miami = 2hrs 35min
Boston = 1hr 15min
Atlanta = 1hr 55min
Indianapolis = 1hr 40min
