If z=3 and z*y=12 what does y+5 equal
1 answer:
Z = 3 (This equation is a given) z(y) = 12 ( This equation is also given) 3y = 12 (as z = 3, plug 3 into z) 3y/3 = 12/3 (isolate the y by dividing 3 to both sides) * you divide 3 to both sides because of the equal sign. What you do to one side you do to the other y = 4 (answer for y) y + 5 (what you are solving for) (4) + 5 = 9 (As y = 4, plug in 4 for y in this equation) y + 5 = 9 (4 + 5 = 9, or addition property)9 is your answer hope this helps

So remember that (a/b)(c/d)=(ac)/(bd) convert to imporoper number for easy 4 and 1/4=4+1/4=16/4+1/4=17/4 2 and 2/3=2+2/3=6/3+2/3=8/3 length times base=17/4 times 8/3= (17 times 8)/(4 times 3)= 136/12= 34/3= 33/3+1/3= 10+1/3= 10 and 1/3 square yards area is 10 and 1/3 square yards
Area =
Therefore, area of square is 88.36 cm².
