Gizmo can eat 10/3 * 2 = 6 2/3 bowls in 10 minutes
Leo can eat 10/6 * 1 = 1 2/3 bowls in 10 minutes
Together they can eat 8 1/3 bowls in 10 minutes.
Answer:
-0.7
Step-by-step explanation:
First do 3.2-1.8= 1.4. So now we know that -2n=1.4. Next you solve for n to get the answer of -0.7 with your answer of the third option.
If the number is n then
square of 2 times a number
square of 2n
(2n)²
that was your mistake, because (2n)²=4n², not 2n²
the result is 81
(2n)²=81
square root both sides
remember positive and negative roots
2n=+/-9
divide by 2
n=+/-4.5
n=4.5 or -4.5
Step-by-step explanation:
5x + 80 = 180
x = 20
2x = 40
3x=60
7x=140
