Answer:
C. 47
Step-by-step explanation:
5(8 + 7)
Expand the brackets. Brackets mean to multiply.
5(8 + 7)
5 * 8 + 7
= 40 + 7
= 47
Answer is D... the -3 outside the absolute/parenthesis shifts is down
Answer:
AB = square root of 403
Step-by-step explanation:
use the pythagorean theorem to solve for AB.
a^2 + b^2 = c^2
9^2 + b^2 = 22^2
81 + b^2 = 484
b^2 = 484 - 81
b^2 = 403
b = 20.07
We have that
<span>(x+2)(y+3)=0
we know that
Part A)
the x-intercept is when y=0
for y=0
</span>(x+2)(0+3)=0--------> (x+2)*3=0------> 3x+6=0----> 3x=-6----> x=-2
the point is (-2,0)
Part B)
the y-intercep is when x=0
for x=0
(0+2)(y+3)=0-----> 2*(y+3)=0-----> 2y+6=0----> y=-6/2-----> y=-3
the point is (0,-3)
Amount spent = $40 - $10 = $30
Price for each bag of popcorn = Amount spent / Number of bags of popcorn bought
Price for each bag of popcorn = 30 / 12 = $2.5
