Answer:
$10.25
Step-by-step explanation:
Set up a system of equations, so 3c + 2m = 7 and 2c + 4m = 8, where c = the cost of coffees, and m = cost of muffins
To solve multiply the first equation by -2(3c + 2m=7) so you get -6c -4m = -14 now add the two equations
-6c - 4m = -14
2c + 4m = 8 notice that -6c + 2c = -4c and -4m + 4m cancels, then -14+8=-6
so we have -4c = -6 so c = $1.50
To solve for m, substitute c = 1.50 so 3(1.50) + 2m = 7, so solve for m so
4.5 + 2m = 7, 2m = 2.5, so m = $1.25
So now solve the final problem 6(1.50) + 1(1.25) = $10.25
Answer:
UNit rate is 3 equation:y=3x
Step-by-step explanation:
Answer:
No the ramp doesn’t meet the law. The slope is 4/50 which is 1/12.5
The slope of the ramp doesn’t meet the law because it’s slope is greater than 1/12. To adjust the ramp so that it meets the law, you could increase the height and/or the horizontal length to increase the slope so it is less than 1/12.

Answer:
(-4 , 0] ∪ (2, ∞)
Last option
Step-by-step explanation:
Since range is included 2 so (2, ∞) and other line is not included 0 but included -4 so it should be (-4, 0]
So range would be:
(-4 , 0] ∪ (2, ∞)
