<span>A) m > 0 and b > 0
that's what i think it is. If its not im sorry.</span>
Answer: The system of equations represents the constraints in this situation are:
s + h = 40
$18s + $14h = $700
The above equations are known as simultaneous equations. 40 scarves and hats were sold, this can be represented with this equation:
number of hats sold + number of scarves sold = 40
s + h = 40
The total amount made from the sales is the sum of the total amount made from the sale of the hats and the total amount made from the sale of the scarves. This can be represented with this equation:
($18 x s) + ($14 x h) = $700
Step-by-step explanation:
EQUATION 1) 2x - 3y = -4
EQUATION 2) 7x + 9y =- 5
Multiply the whole first equation by 3 so that we could find the values of X first.
1) 3(2x - 3y = -4)
1) 6x-9y=-12
2) 7x+9y=-5
Add the 2 equations together.
13x=-17
x=-17/3 OR -5 2/3
2x-3y=-4
Plug the value of X into the equation.
2(-17/3) -3y=-4
-11 1/3 - 3y=-4
-3y=-4+11 1/3
-3y=22/3
y=-22/9 OR -2 4/9
~Hope I helped!~
These two quantities obviously refer to a picture or drawing that shows how they're related to each other. Without the picture, they're not related, and there's no answer.
Answer:
2/7
Step-by-step explanation:
I'm not 110% sure, but I believe its like a ratio. Theres 2 blue socks out of 7 total. Hoped that helped ;)
