Question 18 (1 point)
The picture shows Earth's movement around the Sun.





How does Earth's movement around the Sun affect the average monthly temperatures in Atlanta, Georgia?

a
Earth's distance from the Sun causes Atlanta to get different amounts of sunlight as it moves around the Sun.
b
Earth's orbital path causes Atlanta to get the same amount of sunlight as it moves around the Sun.
c
Earth's tilt on its axis causes Atlanta to get different amounts of sunlight as it moves around the Sun.
d
Earth's rotation on its axis causes Atlanta to get the same amount of sunlight as it moves around the Sun.

a
It is summer because Earth is farther away from the Sun.
b
It is summer because the northern part of Earth is tilted toward the Sun.
c
It is winter because the northern part of Earth tilts away from the Sun.

Jabari had two equations to solve. Both had two unknowns, x and y. Jabari could use them to solve each other. That's called (_______). Jabari decided to (_______) using the substitution method. First, he had to turn the x's in one equation into y's. He subtracted 2y from both sides of the first equation x+2y = 4. This made x = 4−2y.
Next, he substituted the expression 4−2y for x in (_______). Now he had (4-2y)−2y = 6.
Jabari saw that the two 2y's were like terms. He knew that collecting like terms is a way to (_______). He combined the y's to get 4−4y = 6.
From there, he subtracted 4 from both sides to get −4y=2. Now it was easy to evaluate the expression down to a single value. The problem's solution was (_______).
