16 ounces in a pound.
120/16 = 60/8 = 30/4 = 15/2 = 7.5

7.5 lbs = 120 oz
7.5 lbs > 7 lbs

1 pound is equal to 16 ounces.

7 * 16 = 112

So 7 pounds is equal to 112 ounces.

Therefore 120 ounces is greater than 7 pounds.

0.18=..........- -18+-1.8​
-Dominant- [34]

Answer:

-16.02

Step-by-step explanation:

I assume the "......" is a variable replacement. I will use x instead.

0.18 = x - - 18 + - 1.8

Negative + Negative = Positive

0.18 = x + 18 + - 1.8

Positive + Negative = Negative

0.18 = x + 18 - 1.8

Combine like terms

0.18 = x + 16.2

Subtract both sides by 16.2 to isolate the variable x

0.18 - 16.2 = x + 16.2 - 16.2

-16.02 = x + 0

-16.02 = x

Check your work:

Plug in -16.02 into the original equation

0.18 = -16.02 + 18 - 1.8

They should equal each other; let's check to make sure

0.18 = 1.98 - 1.8

0.18 = 0.18

They equal each other so our answer is correct

M∠1=28°, m∠6=65°, m∠5=65°. Find m∠MAX
kirill115 [55]

Answer:

<MAX = 93

Step-by-step explanation:

Since <MAX is technically <1 + <5, we know that <1 is 28 and <5 is 65. We can add both of these angles up to solve for <MAX, which is 28 + 65 = 93.
