1. if 5 sips + 4 gulps = 1 glass and 13 sip
+ 7 gulps = 2 glasses, how many sips
equal a gulp?

3.5 sips

Step-by-step explanation:

you divide 7 by 2 and you would get 3.5

3 sips = 1 gulp

Step-by-step explanation:

We will solve this problem using the given simultaneous equations. We will use either substitution or elimination. For this problem, we will use elimination.

Let s = No. of sips

Let g = No. of gulps

5s + 4g = 1 -> (1)

13s + 7g = 2 -> (2)

We will multiply the first equation by 7 and multiply the second equation by 4 so that both equations have '28g'.

5s + 4g = 1 -> (1) × 7

13s + 7g = 2 -> (2) × 4

35s + 28g = 7

52s + 28g = 8

We will subtract the second equation from the first equation.

- 17s = - 1

s = - 1 / - 17

s = 1 / 17

We will substitute the obtained value for 's' into the first equation to solve for 'g'.

5 ( 1 / 17 ) + 4g = 1 -> (1)

5 / 17 + 4g = 1

4g = 1 - 5 / 17

g = ( 12 / 17 ) / 4

g = 3 / 17

Therefore, as 3 / 17 ÷ 1 / 17 = 3:

3 sips = 1 gulp

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

.95
