Answer:
Where is the motherfzcking link you are so trash at Brainly.
Cost of both the Company A & B is $200 we can use any company . Other factors which is seen is that which company give better quality of mulch , buy from there ! Also , for an instance buying from Company B will be good as you can buy much more mulch with rate of $1.50 , Prefer Company B when you need to buy mulch more than 100 cubic feet .
<u>Step-by-step explanation:</u>
Here we have , A group of students wants to put mulch in some flower beds near their school. It will take 100 cubic feet to mulch the entire flower bed. Company A sells bags of mulch for $2 per cubic foot. Company B will deliver a truckload at $1.50 per cubic foot, but charges a $50 delivery fee. We need to Write an equation to model each situation. Then decide which company should be used. Are there other factors to consider other than cost . Let's find out:
There is 100 cubic feet to mulch the entire flower bed .
- Company A sells bags of mulch for $2 per cubic foot.
According to this , total cost for 100 cubic feet by Company A sells is :
⇒
⇒
- Company B will deliver a truckload at $1.50 per cubic foot, but charges a $50 delivery fee
According to this , total cost for 100 cubic feet by Company B sells with $50 as delivery charge is :
⇒
⇒
Since, Cost of both the Company A & B is $200 we can use any company . Other factors which is seen is that which company give better quality of mulch , buy from there ! Also , for an instance buying from Company B will be good as you can buy much more mulch with rate of $1.50 , Prefer Company B when you need to buy mulch more than 100 cubic feet .
Answer:
45
Step-by-step explanation:
Answer:
13.5
8.64
Step-by-step explanation:
1) 9/100 * 150 = 13.5
2) 12/100 *72= 8.64
it means if some thing represents 9 of 100 , so by how much will it represent of a certain number (ex: 150)
Answer:
(9, -15)
Step-by-step explanation:
First, label the 2 equations:
-10x -6y= 0 -----(1)
-4x -6y= 54 -----(2)
(2) -(1):
(-4x -6y) -(-10x-6y)= 54 -0
-4x -6y -(-10x) -(-6y)= 54 (expand, simplify)
-4x -6y +10x +6y= 54 (expand)
10x -4x= 54 (simplify)
6x= 54
x=54 ÷6
x= 9
susbt. x=9 into (1):
-10(9) -6y=0 (subst. x=9 into -10x-6y=0)
-90= 6y (bring y term to the other side)
6y= -90
y= -90 ÷6
y= -15
Thus, the solution is (9, -15).
