16oz is one pound and the puppy is already 514 so not it's
514.5(decimal)
(fraction)
A. solve for 1 variable
let's solve for x in 2nd equation
add 2y to both sides
x=2y+4
sub 2y+4 for x in other equation
3(2y+4)+y=5
6y+12+y=5
7y+12=5
minu12 both sides
7y=-7
divide 7
y=-1
sub back
x=2y+4
x=2(-1)+4
x=-2+4
x=2
(2,-1)
B. eliminate
eliminate y's
multiply first equation by 2 and add to first
6x+2y=10
<u>x-2y=4 +</u>
7x+0y=14
7x=14
divide by 7
x=2
sub back
x-2y=4
2-2y=4
minus 2
-2y=2
divide -2
y=-1
(2,-1)
(2,-1) is answer
Please find the attached graph.
Let x represent number of shirts and y represent number of caps.
We have been given that Mikhael, Hema, and 5 friends will help run their school's fundraiser. They will wear either a red shirt or a red baseball cap during the event.
Since there are 7 people in total, so total number of caps and shirts will be 7. We can represent this information in an equation as:
We are also told that Shirts cost $8 each and caps cost $4 each. So cost of x shirts would be and cost of y caps would be .
Since they want to spent exactly $40, so cost of x shirts and y caps will be equal to 40. We can represent this information in an equation as:
We can divide equation (2) by 4 as:
We can see from our attached graph that solution of this system is (3,4), therefore, 3 friends will wear shirts and 4 will wear caps to stay in the budget.
