Answer:
80 sqcm
Step-by-step explanation:
area of the full rectangle is 96 sqcm (12x8) and then you subtract the area of the cutout (4x4)
The numbers are 15,18
They add to 33 and a difference of 3
Answer:
you can
Step-by-step explanation:
they are not like terms because the number 6 has and x next to it and 17 doesn't
X: earn per hour during the week
y: earn per hour during the weekend
13x + 14y = 250.90
15x + 8y = 204.70
Multiply the first equation by 4 and the second equation by 7
52x + 56y = 1003.6
105x + 56y = 1432.90
Subtract the first equation from the second:
53x = 429.30
x = 429.30/ 53
x = 8.10
Solve any of the equation for y:
15x + 8y = 204.70
y = [204.70 - 15(8.10)]/8 = 10.40
y - x = 10.40 -8.10 = 2.30
Answer: she earns $2.30 per hour more during the weekend than during the week.
Your blood circulates a total of 128 times a hour, or 3 times a minute.
