First substitute .5x in for y to get a solvable equation. You should get 6x+8(.5x)=30. Then multiply 8 times .5 to get 6x+4x=30. Then combine like terms (6x+4x) to get 10x=30 and divide both sides by 10 to get x=3. Then plug this x value (3) into the other equation (y=.5x) to find the value of y. Y=.5(3) so y=1.5. Therefore the answer is B.
Step-by-step explanation:
First;
x to third power=x³
y to 4th power=y⁴

Step-by-step explanation:
140/70=2 Therefore, 1 apple equals 2 percent
The remaining 30 percent times 2 equals 60
60 apples plus 140 apples equals 200 apples
Answer B
