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
The value of x is 7 and the lengths of the sides are 16, 11 and 8
<h3>How to determine the values of x and each side?</h3>

The perimeter is calculated as:
P = 3x - 5 + 2x-3 + 15 - x
Evaluate
P = 4x + 7
The perimeter is 35.
So, we have
4x + 7 = 35
This gives
4x = 28
Divide by 4
x = 7
Substitute x = 7 in 3x - 5, 2x-3 and 15 - x
3x - 5 = 3* 7 - 5 =16
2x-3 = 2* 7 - 3 = 11
15 - x= 15 - 7 = 8
Hence, the value of x is 7 and the lengths of the sides are 16, 11 and 8

Answer:
23
Step-by-step explanation:
100 is the exterior angle.
( 2x + 3 ) and 51 are interior angles.
Formula : -
Exterior angles = Sum of two interior angles.
100 = 2x + 3 + 51
100 = 2x + 54
2x = 100 - 54
2x = 46
x = 46 / 2
x = 23
Given proportional relationship between the number of oatmeal raisin cookies Jane buys, x, and their total cost (in dollars), y shows you that
y=x.
You can check it:
- when x=6 cookies, then y=$6 (x=y);
- when x=8 cookies, then y=$8 (x=y);
- when x=15 cookies, then y=$15 (x=y);
- when x=18 cookies, then y=$18 (x=y).
Answer: y=x.
