Question

If 3x + y = 18, then 2(3x +y) =__________ (1 point) 36 2. if x =5, then 2x +5 is how much more than x?__________ (1 point) 10 3. if x + y = 12, then 3x +3y = ?__________ (1 point) 36 4. if 5.353=53k, what does k equal?__________ (1 point) 5. if x =3.6 and y=6.4, then 100(x + y) = __________ (1 point)

Answer 1

if 3x + 8 = 18, then 2(3x + y) = 36

if x = 5, then 2x + 5 is 10 more then x

if x + y = 12, then 3x + 3y = 36

if 5.353 = 53k, then k = 0.101

if x = 3.6 and y = 6.4, then 100(x + y)

Answer 2

If 3x + 8 = 18, then 2(3x + y) = 36
if x = 5, then 2x + 5 is 10 more then x
if x + y = 12, then 3x + 3y = 36
if 5.353 = 53k, then k = 0.101
if x = 3.6 and y = 6.4, then 100(x + y) = 1000
