6x+2x=222, which means 8x=222. Thus, x=222/8, which is 27.75.
Hello there.
We have for a circle that:
Where:
is the measure of the arc
is the measure of the angle (radians)
is the radius of the circle
In our case, we have 
We have r = 3 cm, then:
Rosa has saved $490 in 6 weeks.
To find the answer to this, simply plug the number of weeks in for the value of x and solve.
f(x) = 250 + 40x
f(6) = 250 + 40(6)
f(6) = 250 + 240
f(6) = 490
Answer:
AB = 25
Step-by-step explanation:
First things first, we know that these triangles are similar. Now let's find BC using the Pythagorean Theorem. BC = 
, this side is similar to the 5 side of the smaller triangle. That means each side of the larger triangle 
times larger than the corresponding side on the small triangle. That means AB is times larger than BC as well. So multiply BC by get us the answer.
