Hopefully this is the correct answer! but your expression would be: y=40x+30
and if he drove for 5hrs then you would plug in 5 for your x value so it would be y=40*5+30 and 40*5 is 200.(the star means multiplying) then add 30 to get a total of $230
so the expression is: y=40x+30
and if he drove for 5hrs then he sould make a total of: $230
hopefully that helped and was the right answer :)
64 + 5 = 69
69 + 64 = 133 cupcakes
Answer:
3/4
Step-by-step explanation:
Set up a proportion. 4 3/4 cup broth is to 10 servings as x cups broth is to 1 serving soup.
x= amount of broth in one serving
(4 3/4)/10= x/1
cross multiply
(4 3/4)(1)= 10x
convert 4 3/4 to improper fraction
(19/4)(1)= 10x
19/4= 10x
divide both sides by 10
19/4 ÷ 10= x
to divide fractions, multiply by reciprocal of 10
19/4 * 1/10= x
multiply numerators; multiply denominators
(19*1)/(4*10)= x
19/40 cup= x
ANSWER: 19/40 cup in one serving
Hope this helps! :)
11)
3x = 180
x = 60
12)
6x + 18 = 180
6x = 162
x = 27
