Answer:

Carlton thinks that converting metric units is as easy as moving the decimal point

Step-by-step explanation:

When you convert the unit, you move decimal point on your answer from the left to the right or from the right to the left the number of places as per relevant prefix.

Example:

1 meter = 1000 millimeters (1.0 m = 1000.0 mm)
1 milligram = 0.001 grams ( 1.0 mg = 0.001 g)

6²=36
2(3)=6
So now we have
36/6 + 4 which is 6 + 4 which is 10.

The slope formula can be used to find the slope, m, of a line with points (L1, y1) and (22, 42).

Helga [31]

Answer: $(y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)$

Step-by-step explanation:

Point slope form: $(y-b)=n(x-a)$ , where n=slope , (a,b) is the point through which line passes.

If slope of the line = m and line passes through $(x_1,y_1)$ and $(x_2,y_2)$ :-

$(y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)$

So, the equivalent equations are :

$(y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)$

A movie theater charges 8 dollars for adults and 4 dollars for seniors. On a particular day when 353 people paid an admission, the total receipts were 1688 dollars. How many who paid were adults? . How many who paid were seniors?

Answer:

There were 69 adults and 284 seniors

Solution:

Let "a" be the number of adults

Let "s" be the number of seniors

Cost of 1 adult = $ 8

Cost of 1 senior = $ 4

On a particular day when 353 people paid an admission

Therefore,

number of adults + number of seniors = 353

a + s = 353

a = 353 - s ---------- eqn 1

The total receipts were 1688 dollars

Therefore, we frame a equation as:

number of adults x Cost of 1 adult + number of seniors x Cost of 1 senior = 1688

$a \times 8 + s \times 4 = 1688$

8a + 4s = 1688 ---------- eqn 2

Let us solve eqn 1 and eqn 2

Substitute eqn 1 in eqn 2

8(353 - s) + 4s = 1688

2824 -8s + 4s = 1688

4s = 2824 - 1688

4s = 1136

Substitute s = 284 in eqn 1

a = 353 - 284

Thus there were 69 adults and 284 seniors in movie theater
