x+y=23 and 10x+24y=426 can be used to determine the number of small and large boxes shipped where x represents the number of small boxes and y represent the number of large boxes.
Step-by-step explanation:
Given,
Volume of small box = 10 cubic feet
Volume of large box = 24 cubic feet
Total boxes shipped = 23
Combined volume = 426 cubic feet
Let,
x represent the number of small boxes.
y represent the number of large boxes.
x+y=23
10x+24y=426
x+y=23 and 10x+24y=426 can be used to determine the number of small and large boxes shipped where x represents the number of small boxes and y represent the number of large boxes.

Answer:
Step-by-step explanation:
percent increase = ((new number - original number) / (original number)) * 100
= ((910 - 650) / 650) * 100
= (260 / 650) * 100
= 0.4 * 100
= 40% <===== Maki's increase
Answer:
11° and 79°
Step-by-step explanation:
Complementary angles sum to 90°
let x be one angle then the other angle = x + 68 , hence
x + x + 68 = 90
2x + 68 = 90 ( subtract 68 from both sides )
2x = 22 ( divide both sides by 2 )
x = 11
The 2 angles are x = 11° and x + 68 = 11 + 68 = 79°
As a check : 11 + 79 = 90
y=kx
Substitute the given x and y values, and solve for k .
30=k⋅6
k=5
The equation is y=5x . Now substitute x=100 and find y .
y=5⋅100y=500
