Answer:

chocolate chips: $3.75

walnuts: $2.5

Step-by-step explanation:

lets say chocolate chips cost x dollars and walnuts cost y dollars. we then have

6x + 5y = 35

2x + 3y = 15

multiply the second equation by 3 to get 6x + 9y = 45

subtract the 1st equation from the new equation to get 4y = 10, so y=$2.50

plug this value into the 2nd equation to get x=$3.75

Answer: 5°

Step-by-step explanation:

You can use a right triangle to solve

Hypotenuse would be the flight path

One leg (opposite) is the tree 65 ft

Tan (Θ) = opposite/ adjacent = 65/750

Θ = arctan (65/750)

Θ = 5°

Solve logarithm Equation: log2 (12b - 21) - log2 (b^2 - 3)=2

Vikki [24]

Hn, well you should use the rule to answer this.. $log_a(n)-log_a(m)=log_a (\frac{n}{m} )$
Sorry if this doesn't seem to help, but here is the explanation:
$log_2 (\frac{12b-21}{b^2-3} )=2$
$\frac{12b-21}{b^2-3} =4$
$12b-21=4(b^4-3)$
$0=4b^2-12b-12+21$
$0=4b^2-12b+9
$
$0=4b^2-6b-6b+9$
$0=2b(2b-3)-3(2b-3)$
$0=(2b-3)(2b-3)$
$b= \frac{3}{2}$
Hn, so from this information we can determine that this solution does not work. And so forth your solution set shall indeed be: {x= 0}

I wish you good luck on your homework and hopefully I was somewhat beneficial to your needs.

What is the value of x?<br> Enter your answer in the box<br> 39<br> X=<br> 102°

ddd [48]

Answer:

x=39

Step-by-step explanation:

The interior angles add up to 180 degrees so you do 39+102, which is 141. Then you subtract 141 from 180 and then you get 39 degrees.
