Suppose you know that <T and<S are supplementary, and that m<T=3(m<S). How can you find m<T?

stealth61 [152]

Answer:

∠T = 135°

Step-by-step explanation:

Supplementary angles sum to 180°, thus

∠T + ∠S = 180

However, ∠T = 3∠S, hence

3∠S + ∠S = 180

4∠S = 180 ( divide both sides by 4 )

∠S = 45°, hence

∠T = 180° - 45° = 135°

5 pounds of almonds cost $25. What is the unit price per pound?

denis23 [38]

Answer:

Step-by-step explanation:

To find the unit price, we have to divide the price, $25, by the number of units, 5.

$\frac{25}{5}$ = 5

So, the unit price is $5 per pound.

Good luck ^^
