Answer:
YZ = 12.2
Step-by-step explanation:
YZ bisects XW and VW, therefore it is half of XV
24.4/2 = 12.2
The larger number is 12, because the difference between 12 and 2 is 10 and 12 is larger than 2.
9.48 but if rounded its 9.5
Make this on form of a simultaneous equation:
assume jelly beans is J and trail mix is T
8J+4T=21
3J+2T=9
then solve
multiply the first equation by 3 and second equation by 8(SO THE J CAN DISAPPEAR[ELIMINATION METHOD])
24J+12T=63
24J+16T=72
Subtract
-4T=-9
T=0.44
then substitute the T to any one of the equation
3J+2(0.44)=9
3J+0.88=9
3J=8.12
J=2.71
therefore, jelly beans= $2.71 and trail mix=$0.44
Answer:
1/2x+5
Step-by-step explanation:
y = 2x-10
Exchange x and y
x = 2y -10
Solve for y
x + 10 = 2y-10+10
x+10 = 2y
Divide by 2
x/2 + 10/2 = 2y/2
1/2x +5 = y
The inverse is 1/2x+5
