Answer:
16
Step-by-step explanation:
9x-48=-6y
=-48=-6y+9y
=-48=-3y
y=-3/-48
y=16
34+x+90 =180(Angle sum property of triangle )
124 +x =180
x= 180-124
x= 56
<h3>So option c is the correct one!!</h3>
Answer:
(3y+z)/20
Step-by-step explanation:
Begin by moving 3y to the right side of your equation:
20x=3y+z
Then divide both sides by 20 isolating x on one side of your equation:
x=(3y+z)/20
There are 82 boats in the navy. 48 of them are battleships and the rest are destroyers. What is the ratio of the number of destroyers to the number of battleships?
Let
x -----> the number of destroyers
y ----> the number of battleships
the ratio is
x/y
we have
y=48
x=82-48=34
therefore
ratio=34/48
simplify
34/48=17/24
answer is 17/24 or 17:24
It's equal to, both sides equal 32.
