Answer:
Chocolate Chips cost $2.25 and Walnuts cost $3.25 per pound each
Step-by-step explanatChocion:
Let x = cost of pounds of chocolate chip cookies and y = cost of pounds of walnuts.
From the question, we get 5x+3y = 21 and 2x+6y = 24. To solve the equation, we use substitution. From the first equation, we get y = (21-5x)/3. We substitute the y into the second equation to get 2x + 6(21-5x)/3 = 24. This turns out to be 2x+(42-10x) = 24. Adding like terms you should get 42-8x = 24. Solving for x, x = $2.25 per pound. Plugging this into the first equation, we get 5(2.25)+3y = 21. Solving for y, we get $3.25 per pound of walnuts. If we plug in the numbers into the 2 equations, we will get the right total.
Hello
5^(2x) = 27
if : a>0 and b>0 a = b <span>equivalent to log(a) = log (b)
</span> log (5^(2x)) = log(27) ... (1)
a>0 and b>0 log(a^n) = nlog(a)
(1) equivalent to :<span>2x log 5 = log 27</span>
Answer:
142.85 (rounded off to two decimal places)
Step-by-step explanation:
given
(49/100)x = 56
x = (56/49)100
x = (8/7)(100)
we get
x= 142.85....
Answer:
I think its D., but dont trust me
Step-by-step explanation:
We’ll subtract the exponent in the denominator from the exponent in the numerator, keeping the base the same. Cant be simplified, because the base of the expression in the numerator is y and the base of the expression in the denominator is x.
