Answer:
11 pounds
Step-by-step explanation:
Let x pounds of chocolate costing $16.50 per pound mixed with 13 pound of trail mix costing $2.90 per pound to create a mixture worth $9.13,
Thus, the total quantity of trail mix = ( x + 13 ) pounds,
Also, the cost price of x pounds of chocolate + cost price of 13 pounds of trail mix = cost price of resultant trail mix
∵ total cost = number of pounds × price per pound
⇒ 16.50x + 2.90(13) = 9.13(x+13)
⇒ 16.50x + 37.7 = 9.13x + 118.69
⇒ 16.50x - 9.13x = 118.69 - 37.7
⇒ 7.37x = 80.99
⇒ x = 10.989145 ≈ 11
Hence, 11 pounds of chocolate should be mix.
Answer:
x=6
Explanation:
−2(x−4)=−4
Step 1: Simplify both sides of the equation.
−2(x−4)=−4
(−2)(x)+(−2)(−4)=−4(Distribute)
−2x+8=−4
Step 2: Subtract 8 from both sides.
−2x+8−8=−4−8
−2x=−12
Step 3: Divide both sides by -2.
−2x / -2 = -12 / -2
x=6
If and , the product of x and y is
x× y
÷ xy
Answer:
2.7g/cm^3
step-by-step explanation:
The vertex of the given equation is which shows that the value of the market after about 5 years is about 187,253.01
<h3>Functions and values</h3>
Given the overall value of a home can be modeled by
V(x) = 415x^2 – 4600x + 200000
Write in vertex form to have:
V(x) = 415x^2 – 4600x + 200000
For the given equation, the vertex occur at
Hence the vertex of the given equation is which shows that the value of the market after about 5 years is about 187,253.01
