Answer:
4/1/4
Step-by-step explanation:
48÷6
=8-3 3/4
=4/1/4
Answer:
7, 9, 17
Step-by-step explanation:
The sum of the two smallest numbers has to form a number larger that the largest number, and 7 + 9 = 16 which is less than 17.
Answer:
x = 42
Step-by-step explanation:
The marked angles are supplementary, so their sum is 180°.
(2x +8) +(2x +4) = 180
4x +12 = 180 . . . . . . . . . simplify
x +3 = 45 . . . . . . . divide by 4 (because we can)
x = 42 . . . . . . subtract 3

<em>Additional comment</em>
A "two-step" linear equation like this one is usually solved by subtracting the unwanted constant, then dividing by the coefficient of the variable. Here, we have done those steps in reverse order. This makes the numbers smaller and eliminates the coefficient of the variable. Sometimes I find it easier to solve the equation this way.
What would you like to know? The total surface area? The lateral surface area? The volume, perhaps? The radius?
