Answer:
6 children
Step-by-step explanation:
If all of the group were adults, the total cost of tickets would be 8×$10 = $80. The actual cost was $80 -62 = $18 less than that. Since each children's ticket saves $3 off the cost of an adult ticket, there were $18/$3 = 6 children's tickets.
There were 6 children in the group.
_____
If you want an equation, you can let c represent the number of children. Then the cost of tickets is ...
8(10 -c) +5c = 62 . . . . 10-c is the number of adults
-3c = -18 . . . . . . . subtract 80
c = -18/-3 = 6 . . . divide by 3
Answer:
ln(x)
Step-by-step explanation:
ln(x) can be rewritten as e^ln(x)=x. so if e^ln(1)=1 the exponent is just 0. because anything to the power of 0 is 1 according to the Zero Exponent Rule
Answer:
10,000,000
Step-by-step explanation:
You multiply all of the digits on the bottom starting from right to left with the numbers on the top (Biggest number on top smallest on bottom). after you multiplied 5000 by the first zero in 2000 you go down a line (Lined paper is the best to use) and add a zero as a place holder and then multiply 5000 by the second zero in 2000 then after that you go down a nother line and add two zeros for a place holder... you repeat the steps of multiplying and go down another line and add three zeros as place holders. after your finnished multiplying you add all the numbers in your lines together and you will get 10,000,000

Answer:
a. y = 2+4.3x when x = -6
substituting value of x, we get
<u>y=2+4.3*-6=2-25.8=23.8</u>
b. y = (x-3)² when x = 9
substituting value of x, we get
<u>y</u><u>=</u><u>(</u><u>9</u><u>-</u><u>3</u><u>)</u><u>²</u><u>=</u><u>6</u><u>²</u><u>=</u><u>3</u><u>6</u>
c. y=x-2 when x = 3.5
substituting value of x, we get
<u>y</u><u>=</u><u>3</u><u>.</u><u>5</u><u>-</u><u>2</u><u>=</u><u>1</u><u>.</u><u>2</u>
d. y=5x-4 when x = - 2
substituting value of x, we get
<u>y</u><u>=</u><u>5</u><u>*</u><u>-</u><u>2</u><u>-</u><u>4</u><u>=</u><u>-</u><u>1</u><u>0</u><u>-</u><u>4</u><u>=</u><u>-</u><u>1</u><u>4</u>
