The ideal weight of a nickel is .17637 ounce. A bank teller weighs a roll of nickles to ensure there are 40 in the roll. Write a

n inequality that BEST describes the allowance for an margin of error of .015 of an ounce in the total weight (W) of the roll. The weight of the wrapper is not part of the problem.

an angle measures 24° less than the measure if a supplementary angle . what is the measure of each angle​
vagabundo [1.1K]

Hey there!

If two angles are supplementary, that means that the measures of the two angles have a sum of 180.

If the two angles were of equal measure, they would both be 90 degrees.

The easiest way to get this would be to subtract 12 degrees from one 90 degree angle and add them to the other 90 degree angle so one angle has 24 more degrees then the other.

90 - 12 = 78

90 + 12 = 102

Let's check to make sure this works.

102 + 78 = 180 That checks out.

102 - 24 = 78 That also works.

So, the measures of the angles are 102 and 78.

Hope this helps!

Answer:

\underline{ \boxed{x = 11} } \\ \underline{ \boxed{ABE = 55}}

Step-by-step explanation:

if \: the \: question \: is \to \\  \overline{AZ} \: \perp \: \overline{CD}, \: m \angle{ABE} = 5x, \\ and  \\ \: m \angle{EBD } = 3x + 2\\ but \: m \angle{EBD }  +  m \angle{ABE} = 90 \\ hence \to \\ (3x + 2) + (5x) = 90 \\ 8x + 2 = 90 \\ 8x = 90 - 2 \\ 8x = 88 \\ x =  \frac{88}{8}  \\ \boxed{ x = 11} \\  \\ if \: x = 11, \: then \to \\ m \angle{ABE} = \: 5x = 5(11) \\  \boxed{m\angle{ABE} =55}

State the slope and y-intercept for -y+8x=2x
WITCHER [35]
The slope-intercept form: y = mx + b
m - a slope
b - y-intercept (0; b)

-y + 8x = 2x      |subtract 8x from both sides

-y = -6x      |change signs

y = 6x

Answer: The slope m = 6, y-intercept b = 0 -> (0; 0).
