Answer:$120
Step-by-step explanation:
85% of x= $107.27
.85x=107.27
Divide both sides by .85
X=126.20
Subtract the binder$6.20
9x-9y=-9
x-y=-9/9
x-y+1=0.......(1)
4x-3y=-8
4x-3y+8=0....(2)
combining equation we get
(x-y+1)(4x-3y+8)=0
x(4x-3y+8)-y(4x-3y+8)+4x-3y+8=0
4x²-3xy+8x-4xy+3y²-8y+4x-3y+8=0
<u>4x²+3y²-7xy+12x-11y+8=0</u><u> </u><u>is</u><u> </u><u>your</u><u> </u><u>equation</u><u>.</u>
Because the angle is a straight angle, it means that the total of DEC and CEF would be 180º. (CEF + DEF = 180º) With this information we can make the equasion:
(11x - 12) + (2x + 10) = 180
first, to find x:
to simplify (11x - 12) + (2x + 10) = 180, you add the two equations:
13x - 2 = 180
13x = 182
x = 182/13
x = 14
Now, insert the x (which we found that is 14) to each equation.
DEC: (11 x 14 - 12)
= 154 - 12 = 142
m DEC is 142º.
CEF: (2 x 14 + 10)
=28 + 10 = 38
m CEF is 38º.
<em>check: (CEF + DEC = 180º)</em>
<em>38 + 142 = 180 </em>
therefore, the answers are correct :D
Answer:
7 cm
Step-by-step explanation:
Here is how I solve these problems:
Halve of 6 is 3
10 minus 3 is 7
you subtract 3 from 10 because when you collapse the side (10) onto that side other side (let us call it x), x is shorter that 10 by halve the height.
The amount of defects is not the independent value since you can not choose how many are defects, the independent variable would be the amount of bread made.
