Answer:
5 cartons of eggs
3 packages of steaks
Total cost=$55
Step-by-step explanation:
Hi, to answer this question we have to find the least common multiple of
6 (number of eggs in a carton) and 10 (number of ham steaks in each package)
LCM = 30
6 12 18 24 30
10 20 30 40 50
Since each carton of eggs (x) has 6 eggs, that expression must be equal to 30(eggs) to find the number of cartons.
6 (x ) = 30
Solving for x
x = 30/6
x = 5 cartons
Same process for the steak, where y= number of packages .
10 y = 30
y = 30/10
y=3 packages
Since each carton costs $2 and each package of steaks cost $15:
Total Cost =x 2+y 15
Replacing with the values of x and y calculated
Total cost = (5)2 + (3)15 = 10+45 =$55

Answer:
senior tickets are 12
student tickets are 3
Step-by-step explanation:
s= senior
t = student
10s+5t =135
14s + 3t=177
10s+5t =135
divide by 5
2s+t = 27
multiply by -3
-3(2s+t) = -3*27
-6s -3t =-81
add this to 14s+3t=177
-6s -3t =-81
14s + 3t=177
---------------------
8s = 96
divide by 8
s = 12
senior tickets are 8 dollars
2s+t = 27
2(12) +t = 27
24 +t =27
subtract 24
24+t-24 = 27 -24
t =3
student tickets are 3
Step-by-step explanation:
given x=2
and the equation
to find the value of q , you need to make q the subject in the equation as shown below
q= 3x-x -4
q=2x-4
but x= 2
so just substitute the value of x in the equation for the q
q=4-4
q=0
therefore the value of q is 0

Answer:
500
Step-by-step explanation:
A = the unknown number that we need to find
A x 13/100 = 65
=> A x 13 = 6500
=> A = 6500 / 13
=> A = 500
13% of 500 is 65.
Let's check whether the answer is correct or not.
=> 500 x 13/100
=> 5 x 13
=> 65.
So, the number whose 13% is 65 is 500
