Answer:
Step-by-step explanation:
a). Let the number of spoons = x
And number of forks = y
Total number of spoons and forks bought by Perry = 10
x + y = 10 --------(1)
Cost of one spoon = $5
Cost of one fork = $3
Therefore, total cost of x spoons and y forks = $(5x + 3y)
5x + 3y = 42 -------(2)
b). Now we can convert these equations into the slope-intercept form.
x + y = 10 ⇒ y = -x + 10
Table for input output values,
x 2 4 6
y 8 6 4
5x + 3y = 42
3y = -5x + 42
y = 
x 0 3 6
y 14 9 4
Point of intersection of these lines will be (6, 4).

Complementary angles add up to 90 degrees. 90-66=24. 24 divided by 2 is 12.
Answer:
Half of the depth of swimming pool is 4250 mm.
Step-by-step explanation:
The depth of swimming pool is 8.5 meters. In the question half of the depth is being asked in millimeters.
So we first convert the swimming pool's depth in to millimeters.
= 1 meter = 1000 millimeters
= 8.5 meters = 1000 × 8.5 = 8500 millimeter
Now we multiply it by 
or divide by 2
8500 × = 4250 mm
Half of the depth of swimming pool is 4250 mm.
