Answer: +3

Explanation: Start by plugging in the appropriate values for <em>a</em>, <em>b</em>, and <em>c</em>.

You might also want to change the -4b

to plus a negative 4b to avoid confusion.

Also, use parenthses when substituting numbers in for variables.

So we have 3(3) + -4(4) + 2(5).

Once you have plugged in your numbers, first multiply,

and then add from left to right.

So we have (9) + (-16) + (10).

Now add to get (-7) + (10) which is +3.

KengaRu [80]

Answer:

170.3 miles per hour

Step-by-step explanation:

Javon won Indianapolis 500 race in 2011 with an average speed of 170.265 miles per hour. What was his average speed to the nearest tenth of a mile per hour?

From the above question, we are asked to approximate to the nearest tenth of a mile.

The number that falls under the tenth of a mile, is the number that is immediately after the decimal.

Hence, for:

170.265 miles per hour:

2 is the number in the tenth place, the number after 2 is 6, it is a number that is higher than 5. So we add 1 to 2

Therefore,

170.265 miles per hour to the nearest tenth of a mile = 170.3 miles per hour.
