The corner is 60°, and based on the information given it is D...but if you can measure the angle, it would be B... A and C assume different sizes.
Chris is incorrect. To check the answer, replace m with 8 and simplify the left side. So m/6 turns into 8/6 which converts to the decimal value 1.333 (use a calculator)
Therefore the original equation m/6 = 48 becomes 1.333 = 48 after you plug in m = 8 and simplify fully. The two sides of 1.333 = 48 are not the same, so m = 8 is not the solution.
--------------------
The solution is actually 288 and we can prove it so like this
m/6 = 48
288/6 = 48 .... replace m with 288
48 = 48 .... use a calculator to compute 288/6
So the solution m = 288 is confirmed
------------------
How did I get this answer? By multiplying both sides by 6
m/6 = 48
6*(m/6) = 6*48 ..... multiply both sides by 6
m = 288
So Chris mistakenly divided both sides by 6, which explains how he got 48/6 = 8 as the solution. Instead he should have multiplied both sides by 6. This is to undo the operation "divide by 6" that is being applied to m in the original equation.
F(x) = - x - 5
f(4) = -4 - 5 = -9
Answer: f(4) = -9
20 divided by 12 equals 1.66666 continuous. Rounding on the dollar would be $1.67.
Divide 16 by 8.
16 ÷ 8 = 2.
So, one avocado costs $2.
