The answer is 26.33 repeating
How you get that answer is
First do N times 3
so the you have 3n + 5 = 84
minus 5 from both sides and then you get 3n = 79
divid both sides by 3 and then you get n = 26.33 reapting
What you must do for this case is subtract both quantities and verify the final result.
We have then:
15 3 / 10-13 9/10 =
Rewriting
15.3 - 13.9 =
1.4 =
1 4/10
answer:
this month fell 1 4/10 more centimeters of rain
Answer:
<em>(-2)2 - (-8) + 1</em>
Step-by-step explanation:
When you substitute values into an algebraic equation, you need to input the values exactly how they are given. "w" must go where there are "w"s, and "v" must go where the "v"s are, otherwise you will get an incorrect answer. All values must also carry over their signs--they are one unit--and must be inserted as such, which is why - (-8) is correct, but not - (8) or - 8. (This is because those two negatives will cancel each other out and become +8 when solving). The parenthesis around the values are important because they protect the original values of the variables, which is why (-2)2 is correct. In the case of (-2)2, it also signifies that they are "attached" by multiplication, and when solving would become -4. Without signifying that the variables are separate from the rest of the equation via the parenthesis, it becomes very easy to solve it incorrectly.
When they leave home, odometer reads 12,544.....when they arrive in Winterton, the odometer reads 12,671.....this means they have already driven (12,671 - 12,544) = 127 miles.....and now they have 48 more miles to go......so the trip to Sandy Shores from Summerville is (127 + 48) = 175 miles
