Let x represent the number of US dollars required. From the information given,
1.2 Australian dollars equals one us dollar
Thus,
22 Australian dollars = x US dollars
We would have the following equations
1.2 = 1
22 = x
By crossmultiplying, we have
x * 1.2 = 1 * 22
1.2x = 22
Dividing both sides of the equation by 1.2, we have
1.2x/1.2x = 22/1.2
The expression that can be used to convert 22 Australian dollars to US dollars is
x = 22/1.2
Answer:
23
Step-by-step explanation:
area of a trapezoid = 1/2 × (a + b) × h
so, we have
96 = 1/2 × ((4x - 1) + (x + 3)) × 6 = (5x + 2) × 3
32 = 5x + 2
30 = 5x
x = 6
a = 4x - 1 = 4×6 - 1 = 24 - 1 = 23
Answer:
26
Step-by-step explanation:
12/2=6
x-6=20
x-6+6=20+6
=26

Then by Stokes' theorem we have



which has a value of 0, since each component integral is 0:




Area of triangle = 1/2 x base x height
Given that base = 11 yards and height = 13 yards
Area of triangle = 1/2 x 11 x 13 = 71.5 yards²
Answer; 71.5 yd²
