The answer is 3.3c - 8.2.

First, distribute the -2 to the numbers in the parentheses. Then, add the like terms.

6.3c - 2(1.5c + 4.1)
6.3c - 3c - 8.2
3.3c - 8.2

Hope this helps! :)

(4 tens 3 ones) x 10
adoni [48]

To solve this problem, we must first convert all of the numbers represented by words into their numeral equivalents so we can simplify. To do this, we must remember that the ones place is the first to the left of the decimal point, and the tens place is one place farther to the left. If we have 4 tens and 3 ones, this is the same as 43 (we put the digit 4 in the tens place and the digit 3 in the ones place). If we replace our words with our new numerical value, we get:

43 * 10

To solve this, we just multiply these two numbers together, which gives us:

430

Therefore, your answer is 430.

Hope this helps!

What is 2 divided 1 6/7 ? Please answer
Aliun [14]
If you would like to divide 2 by 1 6/7, you can do this using the following steps:

1 6/7 = 13/7

2 / 1 6/7 = 2 / 13/7 = 2/1 / 13/7 = 2/1 * 7/13 = 14/13 = 1 1/13

The correct result would be 1 1/13.

For which segment lengths is AC¯¯¯¯¯ parallel to DE¯¯¯¯¯ ?
Kruka [31]

Answer:


Step-by-step explanation:

By triangle theorem for similarity we have

AC||DE if and only if

the ratios

\frac{AD}{BD}=\frac{CE}{EB}

Option I:

Here we find the ratios are equal to 1/2

Hence parallel

OPtion 2:

Here we get both ratios equal to 2/3 Hence parallel

Option 3:

Here we get I ratio =2/5 and II ratio =4/7

Since the two are not equal we get not parallel

The experience of a car dealer shows that 60% of the customers purchase a stereo as an option with their cars, 50% purchase tint
erica [24]
If 60% purchase a stereo and 50% purchases tinted windows, then the percentage of people who purchased both have been counted twice. So we have to subtract 35% (the % that purchased both) from the sum of the first two percentages:
60% + 50% - 35% = 75%
Therefore, the probability that a customer picked up any one or both options (which is at least 1) is 75%.
