Answer:
3.3 m
Step-by-step explanation:
The formula used to solve for leg a of a right triangle is a= sqrt(c^2-b^2). This is replaced by sqrt(6^2-5^2) for your equation. If you work this out, it equals about 3.32, and you have to round it to the nearest tenth, so the answer is 3.3 m.
Answer:
6J = 72
Step-by-step explanation:
Because it says the product, it is talking about multiplication.
J would be Jamelle's age
6 is the excess number given.
72 is the answer
thus it would be 6*J or 6J = 72

Answer: You walked 12 dogs
Step-by-step explanation:
If you charge 0.75 per dog then we can represent that by the expression 0.75x where x is the number of dogs. If you charge $5 for the initial amount, then the whole expression will be 0.75x +5 and that has to equal the amount that you earned working on Saturday.So the equation will be
0.75x + 5 = 14 Now solve for x by first subtracting 5 from both sides
-5 -5
0.75x = 9 Divide both sides by 0.75
x = 12
