Answer:
r = 30°
Step-by-step explanation:
According to the Exterior Angle Sum Theorem, the exterior angle, which is 90°, is equal to the 2 interior angles, which are 60° and <em>r°</em>. We know that the angle next to the exterior angle is 90°, and since all angle sums add up to 180°, <em>r</em> = 30°.
Answer:
Step-by-step explanation:
<u>Step 1: Solve for y in the first equation</u>
<u>Step 2: Determine the important aspects</u>
We know that our line is parallel to the other line that has a slope of 1.5 which means that our slope is also going to be 1.5. We also know that our line crosses the point (2, -5) which means that we can use the point slope form to determine our equation
Point Slope Form →
<u>Step 3: Plug in the information and solve</u>
Answer:
Answer:20 gallons
Step-by-step explanation:
Answer: x=3
Step-by-step explanation:
Move all x terms to the same side- x/2-x/3-1/2
Multiply to get common denominator- 3x/6-2x/6=1/2
Subtract 3x/6 and 2x/6 - x/6=1/2
Simplify - x=3
