30-2x>18: inequality
answer: 6 days
Answer:
7c^2
Step-by-step explanation:
I'm assuming you meant "9c^2 - 4c^2 + 2c^2." This comes to:
(9 - 4 + 2)*c^2, or 7c^2.
(7^2)^x = 1
49^x = 1
You should know that anything to the power of 0 is equal to 1, therefore x = 0.
49^0 = 1
Hope that helps :)
1st. 19 goes into 789 41 times. 2nd. Subtract 779 from 789 you will get 10 as the remainder. So the answer is 41R 10
Large box 70, small 55
x+y=125
40x+20y=3900
y=125-x
40x+20(125-x)=3900
40x+2500-20x=3900
20x=1400
x=70
125-70=y
y=55
