Ruby studied her science test for 1/2 of an hour
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Jamal spent 1 1/2 (1.5) hours studying for his science test ruby studied for 1/3 the amount of time that Jamal studied.
Amount of time ruby studied = (1/3) * (1.5) = 1/2 of an hour

Find the circumference:
Circumference = pi x radius x 2 = 138.16 feet
Linear travel = circumference x rotations
linear travel = 138.16 x 20 = 2.763.2 feet.
Round off to 2,763 feet
Answer:
I believe the answer is (2,4)
2/8 divided by 1/4. Steps: 1. Division in math actually means multiplication. You just have to multiply by the reciprocal of the second fraction (reciprocal= denominator and numerator are switched). 2. Do 2/8 times 4/1. 3. 2 times 4= 8 and 8 times 1= 8
4. Your answer would be 8/8 which equals 1. This is how you divide fractions
Parallel = same slope
Find slope of 3x + 5y = 8
Turn into y = mx + b
5y = -3x + 8
Divide by 5
y = -3/5x + 8/5
Slope is -3/5
Y = -3/5x + b, find y intercept
Plug in the point
4 = -3/5(10) + b
4 = -6 + b, b = 10
Final equation: y = -3/5x + 10
