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
Answer: C. 2.6 pounds of apples; 1.2 pounds of bananas.
Answer:
c = 8.54
Step-by-step explanation:
Use Pythagorean theorem and sketch a right triangle with side lengths of 8 and 3, with the hypotenuse labeled as x.
Use the formula a² + b² = c²
8² + 3² = c² Plug in your two numbers into variable
64 + 9 = c² Simplify the squared numbers
73 = c² Add them together
√72 = c Divide the squared variable by using the opposite operation, square rooting
c = 8.54 Plug number into calculator and round
Answer:
A. Bracelets take 3 minutes, and necklaces take 8 minutes.
Step-by-step explanation:
If Mary made 3 necklaces at that rate, it would add up to 24 minutes. A bracelet takes 3 minutes to make, and she made 2, so that would take 6 minutes. Add 24 to 6 and you'll get 30 minutes. I hope this helped :^)
Answer:
f(x)=x(x+4)(x+3)(x-4)(x-3)
Step-by-step explanation:
hello :
an polynomial is : f(x)=(x+4)(x+3)(x-0)(x-4)(x-3)
means : f(x)=x(x+4)(x+3)(x-4)(x-3)
