Answer:
x = 8, y = 4
Step-by-step explanation:
y = x - 4
y = -0.5x + 8
y = y
x - 4 = -0.5x + 8
x + 0.5x = 8 + 4
1.5x = 12
x = 12/1.5
x = 8
To get "y" substitute the 8 for the "x" value in any of the two equations (they will both give the same answer.)
y = (8) - 4
y = 4
OR
y = -0.5(8) + 8
y = -4 + 8
y = 4
Answer:
x= 4
Step-by-step explanation:
2∧(x+1) = 32 = 2∧5
x+1 = 5
x= 4
Answer:
Step-by-step explanation:
This is 30°-60°-90° triangle, so the sides are in the ratio 1:√3:2
The side opposite the 30° angle is 10√3, so the side opposite the 60° angle is √3×10√3= 30, and the side opposite the 90° angle is 2×10√3 = 20√3.
Complete Question
Find the circumference of the pizza to the nearest hundredth.
When Diameter = 18 in.
Answer:
56.55 inches
Step-by-step explanation:
A pizza is circular in shape.
The formula for the circumference of a circle is given as:
πD
Where D = Diameter
From the above question,
Diameter = 18 inches
Hence,
Circumference of the circular pizza = π × 18 inches
= 56.548667765 inches
Approximately = 56.55 inches
The answer b because they are congruent or something
