Answer:
k = 7.3333333 ...
You can round accordingly of write the fraction form
Step-by-step explanation:
4/k = 6/11
6 ÷ 4 = 1.5
11 ÷ 1.5 = 7.3333333 ... (repeating)
4/7.333 = 6/11
Answer:
an inequality symbol means either>or<so in this question 4 u use x<12
Answer:
Step-by-step explanation:
In order for lines to be parallel they have to have the same slope. The first 2 equations there are solved for 5y, so let's do that to the last one--solve it for 5y--and put them all in the same order (the order that the first one is in; they will all look identical then). Equation #2 in the same order as in #1: 5y = 3x - 4. Equation #3 then becomes 5y = 3x - 1. Equations #2 and 3 have the same slope.
