12x + 3y = 15
Solve &Justification

Step-by-step explanation:

12x+3y= 15

12x= -3y+15

divide both sides by 12 and you get

x= -3/12y+15/12

simplifying:

x=-1/4+5/4

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
