Divide 112 by 4 to get 28 then multiply that by 3 to get 84 BOOOM!!
In order to solve this equation that has variables on both sides, you should try to move either one constant term to the other side or one term with a variable to the other side first. Let's add -11x to both sides of the equation (we are carrying out the addition property of equality). Now, you should move a term from the side with more terms to the other side. Let's add 12 to both sides of the equation, so -12+12 will cancel out and equal 0, while 6+12 will equal 18. Finally, divide both sides of the equation by the coefficient of the variable, which is 18. This allows us to isolate the variable. Now, you should have your answer, which is 18/18 (you simplify this :) ) .
Answer:
25 students
Step-by-step explanation:
Let t= total students
Take the total number of students and multiply by the percent that are boys to get the number of boys
t * 40% = 10
Change to decimal form
t*.40 = 10
Divide by .4 on each side
.40t /.4 = 10/.4
t =25
There are 25 students
Answer:
x+y=603
y=x+53
Step-by-step explanation:
Substitute what y equals in the second equation for y in the first equation:
x+(x+53)=603
2x+53=603
-53 -53
2x=550
2 2
x=275 hamburgers
To solve for the number of cheeseburgers, substitute 275 for x in either equation.
y=x+53
y=275+53
y=328 cheeseburgers
To double check your work, make sure that 275+328=603 and that 328=275+53. Since both are true, you have solved for the number of hamburgers (275) and cheeseburgers (328).
