(r is red, g is green and y is yellow)
r+g+y=33
r=3g
2y=r
substitution:
y=33-g-r
y=33-(1/3)2y+2y
y=33-8/3y
11/3y=33
y=33÷(11/3)
y=9
Solve for red and green:
r=2y
r=2×9
r=18
3g=r
3g=18
g=18/3
g=6
double check:
6+18+9=33
answer:
6 green apples, 9 yellow apples and 18 red apples.
Answer:
<em>x ≈ 6.5 , y ≈ 12.1</em>
Step-by-step explanation:
(2x)² + (10.2)² = (16.5)²
4x² = 272.25 - 104.04
x² = 168.21 ÷ 4
<em>x</em> = √(42.0525) ≈ <em>6.5</em>
y² = 42.0525 + 104.04 = 146.0925
<em>y</em> = √(146.0925) ≈ <em>12.1</em>

Answer:
WZ=
UZ=
Step-by-step explanation:
First, you have to find the x.
3x-6+x+6
Combine like terms
(3x+x) (-6+6)
4x+0
x=4.
WZ=3(4)-6
12-6
6
UZ= (4)+6
10
Answer:x=2, y=3
Step-by-step explanation:
solving this equation simultaneously
-9x - 2y=-12.............(1)
2x + 5y=-11.. ...........(2)
Using elimination method
Multiply equation 2 by 2 and equation 1 by 5
-45x -10y= -60...........(3)
4x + 10y=-22...............(4)
Subtracting equation 2 from 1
-41x + 0=-82
41x=82
x=82/41
X=2
To find y put x in equation 1
-9x - 2y= -12
-9(2)-2y=-12
-18-2y=-12
-2y=-12+18
-2y=6
Y= 6/2
Y=3
X=2, Y=3
