Angle Y is a right angle, so it’s 90 degrees. Angle W is 2x, since it’s opposite angles on a single line intersecting parallel lines. Triangles have 180 degrees, so adding up all sides creates the equation to solve:
X+Y+W=180
(3x-5)+90+2x=180
5x+85=180
5x=95
x=19
Given:
Cost of lunch per day = 1 meal and 2 snacks
C = 5.5 + 2(0.75) = 5.5 + 1.5 = 7
7 * 12 days = 84
Based on the choices, the best strategy would be:
<span> A. Make a table. Write the numbers 1 to 12 in the top row of the table (the number of days). In the first box on the second row, write $7. This is how much Rebecca spends in 1 day. In each of the next boxes in the second row, write the amount Rebecca spends by adding $7 to the previous amount. The answer in box 12 is the total amount Rebecca spent after 12 days.</span>
Solve:-
2934/18
2934 ÷ 18 = 163
2934/18 = 183/1 = 183
2934/18 = 183
Speed = distance / time
his travel speed TO the meeting.....
s = 480 / 8 = 60 miles per hr
his travel speed FROM the meeting...
s = 480 / 7.5 = 64 miles per hr
