Answer:
$7.75
Step-by-step explanation:
Given: Adults = 4, Children = 5, All worth = $15, Total cost = $71, Each child's ticket = $5
To find: How much the adult tickets are
Solution: Use the 5 tickets at $5 to get $25
Add the $15 for concessions to reach $40
25 + 15 = 40
Subtract $40 from the 71 spent to get $31
71 - 40 = 31
Now, divide the 31 by 4 for the number of adults which equals $7.75
31 ÷ 4 = 7.75
So, the cost of the adults' tickets is $7.75
If it were me I’d rather be given y=mx+b because you don’t have to use the graph to calculate slope, you just know that m=slope in the equation
Answer:
x = 14
Step-by-step explanation:
Extend line AB so that it intersects ray CE at point G. Then angles BGC and BAD are "alternate interior angles", hence congruent.
The angle at B is exterior to triangle BCG, and is equal to the sum of the interior angles at C and G:
138 = (376 -23x) +(x^2 -8x)
Subtracting 138 and collecting terms we have ...
x^2 -31x +238 = 0
For your calculator, a=1, b=-31, c=238.

<em>Additional comment</em>
You will find that the solutions to this are x = {14, 17}. You will also find that angle BCE will have corresponding values of 54° and -15°. That is, the solution x=17 is "extraneous." It is a solution to the equation, but not to the problem.
For x=14, the marked angles are A = 84°, C = 54°.
Answer:
Either- 200778.9263 or 81
Step-by-step explanation:
Type this into the calculator:
First: (1/9)^6= 1.881676423x10^-6
Then: 81^4= 43046721
Then multiply the two: (1.881676423x10^-6)x 43046721= 200778.9263
Or
Try this- type ((1/9)^6)x(81^4) into the calculator which comes out to 81
((1/9)^6)x(81^4)=81
Depends on which level you are at in math.
The first step for expanding this expression is to use the logarithmic product and the quotient rule.
㏒
(2) + ㏒
(x²) + ㏒
(y)
Lastly,, use ㏒
= x × ㏒
(b) to transform the expression.
㏒
(2) + 2㏒
(x) + ㏒
(y)
This means that the expanded version of your expression is going to be ㏒
(2) + 2㏒
(x) + ㏒
(y).
Let me know if you have any further questions.
