How do you solve this equation 19−4c=17

 Whatever you do to one side, you do the same operation on the other. The goal is to get the variable alone with a number on the other side.

Here's how:

Step-by-step explanation:

19−4c=17

19 - 19 - 4c = 17 - 19  Subtract 19 from both sides  19-19 =0 Cancels on the left

-4c = 17-19   subtract: 17-19 = -2

-4c = -2

-4c/4 = -2/-4    Divide both sides by -4  

Negatives divided by Negatives have a Positive quotient  -4/-4 =1, Cancels

c = 1/2

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
