Answer:
So then Mark purchased 12 Hamburgers and 6 packages of buns
Step-by-step explanation:
For this case we can define the following notation:
B represent the number of packages buns
H represent the number of hamburgers
And from the information given we can set up the conditions into the following equations:
(1) represent the total cost
(2) represent the total number of items
Solving H from equation (2) we got:
(3)
And replacing equation (3) into equation (1) we got:
And dsitributing the terms we have:
And solving for B we got:
And dividing by 5.25 we got:
And replacing the value of B into equation (3) we got:
So then Mark purchased 12 Hamburgers and 6 packages of buns
Answer:
for number 4 the answer is 32 in (please read below)
Step-by-step explanation:
I will do one of them for now... how about number 4.
Similar triangles means we are going to setup a proportion:
Small triangle Big Triangle
Corresponding 12 15
Corresponding x 40
So the proportion is 12/x=15/40
cross multiply
12(40)=15(x)
Divide both sides by 15
giving x=12(40)/15=32
Try number 1... And I will check it for you (just post as a new question-I will be looking for it)
