The answer is simple. To convert a fraction into a decimal take the numerator(the top number) and divide it by the denominator(the bottom number) so the fraction shown above is 4/10. There are two ways. Number 1: u know that 1/10 equals 0.1 so 4/10 equals 0.4 because the 4 needs to be in the tenths place. Number 2: take 4 (numerator) divide it by 10 (denominator) so 4 divided by 10 equals 0.4 so your answer is C=0.40. (PS: 0.4=0.40)

Please help! I'm getting timed.

Hi there! The answer is A.

$t = 2(s + 2)$
To get a proper idea of the type of function this formula represents we work out the parenthesis.

Working out the parenthesis can for instance be done using rainbow technique.
$t = 2s + 4$

We can now see sinilarities between this function an the general function of a line in slope intercept form
$y = mx + n$

The function t therefore describes a line with slope 2 and y-intercept 4. Therefore the answer is A.

4(2-4x)-3x=65 Whats the answer and how did you solve it?

IRINA_888 [86]

Answer:

x= -3

Step-by-step explanation:

Distribute 4(2-4x) which leaves you with 8-16x-3x=65

combine the like terms which leaves you with 8-19x=65

subtract 8 from both sides 8-19x-8=65-8 which leaves you with -19x=57

lastly divide -19 from both sides which leaves you with x= -3

Answer:

2,5 and 6

Step-by-step explanation:

The answer is going to be option 2, 5 and 6 because the line touches -4,2 and 4 on the x axis. And these are the x values so that's why this is going to be the answer.

Hope this information helps you!
