Answer:
y=770-55x --- given
y - 770 = 770 - 55x - 770 ----subtraction property of equality
y = -55x + 770 ---Simplification
y-770/-55 = -55x/-55 --- Division property of equality
-y-770/55=x---Simplification
Step-by-step explanation:
Answer:
720 m²
Step-by-step explanation:
Area = base × height
= 12 × 6
= 72 mm²
≈ 720 m² (1 mm = 10 m)
Answer:
−6a+3b+13
Step-by-step explanation:
Answer:
the distance between the two points is √130.
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 = 9^2 = 81
b^2 = 7^2 = 49
c^2 = 81 + 49 = 130
c = √130
