<span>]to find the number of bananas you have to take the total 3.8 and subtract apples 3.8-a</span>
Answer:
1.5 pounds of apples; 2.3 pounds of bananas
Step-by-step explanation:
x=amount of apples bought. (in pounds)
y=amount of bananas boutht (in pounds)
We can suggest this system of equations:
x+y=3.8
1.9x+0.75y=5.84
We can solve this system of euqtions by substitution method.
x+y=3.8 ⇒ y=3.8-x
1.9x+0.75(3.8-x)=5.84
1.9x+2.85-0.75x=5.85
1.15x=5.84-2.85
1.15x=2.99
x=2.99/1.15
x=2.6
y=3.8-x
y=3.8-2.6
y= 1.2

24000 + 3000x = 30000 + 2400x
3000x - 2400x = 30,000 - 24,000
600x = 6000
x = 6000/600
x = 10 years
Answer:
y= 2x - 11
Step-by-step explanation:
(-7 +1 )/ (2-5) = 2
y= 2x +b
-1 = 2* 5 + b
solve for b and you get -11 so the equation of the line is :
y = 2x -11
Answer:
x< -64

Answer:
2
Step-by-step explanation:
the x and y are being multiplied by 2 e.g. 1 × 2 is 2 and 2 × 2 is 4 so the constant is 2
Y-(-2)= -2/3(x-6)
3y+6= -2x +12
2x +3y +6=0
