Answer:
The correct unit price is $1.17 per pair of gloves. The error is she used number of dozens so, firstly convert it to number of pairs of gloves then divide.
Step-by-step explanation:
It is given 4 dozen pairs of gloves for $56.16.
So, unit price = Divide the price by number of pairs of gloves.
And 1 dozen =12
So 4 dozen =4*12=48 pairs of gloves
So, to find unit rate divide 56.16 by 48.
Unit price =
So, the error is she didn't convert the dozen to units.
That made mistake in finding unit price.
Answer: D (0,8) and (8,8)
Step-by-step explanation:
The equation y= 8 can also be written as y= 0x + 8 which means the slope is always zero.
so if you put in 0 for x you will get 8 as if (0,8)
and if you put in 8 for x you still get 8 because 8 times 0 is 0 plus 8 is 8 as if (8,8)
y=x^2-2x-15 (1) y=8x-40 (2)
8x-40=x^2-2x-15
X^2+10x-25=0
(x-5)^2
×=5 y=0
Answer:
x = 13
Step-by-step explanation:
6x + 14 + 4x - 8 + 2x + 18 = 180 {Angle sum property of tiangle}
6x + 4x + 2x + 14 - 8 +18 = 180 {Combine like terms}
12x + 24 = 180 {Subtract 18 from both sides}
12x = 180 - 24
12x = 156 {Divide both sides by 12}
x = 156/12
x = 13
Step-by-step explanation:
To write a polynomial in standard form, put the degree that are the greatest first
So here it would be
Remember constant are numbers that you learned back in elementary,
Numbers like 10,90,4,1,0,-3 etc.
Remember that constant are basically represented like this
For example, 10 is represented like
Since 0 is the smallest degree possible, for a polynomial, constants are the last term of a polynomial in standard form
