Answer:
C: a reflection across the y axis rotated 180 degrees
Step-by-step explanation:
The y axis is a vertical line, the same like that the trapezoid is flipped across
The trapezoid is rotated 180 degrees across the y axis
Answer:
y =24
Step-by-step explanation:
very simple and direct, just combine the like terms and subtract 3 from 27
and that is the value of your y.
solution
3 + y = 27
y = 27 -3
y =24
Your rows would be $0.90 Chocolate, $1.20 Chocolate, and the Total Chocolate Mix, and your columns would be the Amount of Chocolate in #s and the Total Costs
(This is the best I can do coming up with a grid)
________________amt (#)_________total costs
$0.90_____________10______________9.00
$1.20______________x______________1.20x
Total Mix_________10+x_____________9+1.2x
Using this grid, you see that 10+x=9+1.2x so solve for x
10+x -x=9+1.2x -x
10=9+.2x
10 -9=9+.2x -9
1=.2x
1/.2=(.2x)/.2
x=5, so you need 5lbs of the $1.20 chocolate to produce a mixture worth $1.00
In this case, segment XZ is congruent to segment CA
Congruent triangles mean that both of those triangles have the exact length in all three sides, and had same three angles, which means that we just need to follow the order to find out which segment is congruent when comparing both triangles
<span>A - b</span> - C
X - y - Z
1.5
first there is one four in a six which gives you 1
and then 2/4 is 1/2 which u 0.5
add them and you get 1.5
