30 since 80+70=150 180-150=30
Answer:
none of the above.
Please discuss this question with your teacher.
Step-by-step explanation:
The problem statement tells you that the appropriate interpretation of the point (12, 16) is that <em>the outline of the mountain on the mural is 16 feet from the ground at a point 12 feet from the edge of the mural</em>.
__
There is no information about the base of the mountain or its maximum height, so no conclusions can be drawn regarding those parameters.
Step-by-step explanation:
8-2÷x
it should be written like that
Answer:
Step-by-step explanation:
BASE + 3x = 22.85.....................equation 1
BASE + 10x = 40..........................equation 2
BASE = 40 - 10x
NOW SUBSTITUTE (40-10x) FOR BASE IN THE FIRST EQUATION
40 - 10x + 3x = 22.85
-7x = 22.85 - 40
-7x = -17.15
x = -17.15/-7
x = $2.45 IS THE PRICE FOR EACH POUND.
BASE + 10 x 2.45=40
BASE + 24.50=40
BASE = 40-24.50
BASE = 15.50 IS THE BASE PRICE FOR THE DELIVERY.
PROOF
15.50+3*2.45=22.85
15.50+7.35=22.85
22.85=22.85
Answer:
B and D
Step-by-step explanation:
Write as a quadratic
-2x² - 3x + 5 = 0
Factor
-2x² - 5x + 2x + 5 = 0
-x(2x + 5) + 1(2x + 5) = 0
(1 - x)(2x + 5) = 0
To make the equation 0, x is either 1 or -5/2.
