Answer:
11.25
Step-by-step explanation:
if a cube has 6 equal sides, you want to multiply 5.25 by 6 to get the surface area for the entire cube.
Answer:
Some of the products do not show the correct powers of x.
Step-by-step explanation:
From the picture,
3x(2x - 1) = 6x² - 3x
The correct display on the tile should look like this :
_____+x ______ +x ______ +x
+x __ +x² ______+x² ______+x²
|
+x__ +x² ______ +x² ______+x²

- ___ -x _______ -x _______-x
+6x² - 3x
45 adult tickets and 80 children tickets were sold
<em><u>Solution:</u></em>
Let "a" be the number of adult tickets sold
Let "c" be the number of children tickets sold
Cost of 1 adult ticket = $ 6
Cost of 1 children ticket = $ 3.50
<em><u>They sold a total of 125 tickets</u></em>
Therefore,
a + c = 125
c = 125 - a --------- eqn 1
<em><u>They made a total of $550. Therefore, frame a equation as:</u></em>
number of adult tickets sold x Cost of 1 adult ticket + number of children tickets sold x Cost of 1 children ticket = 550
6a + 3.50c = 550 ----------- eqn 2
<em><u>Let us solve eqn 1 and eqn 2</u></em>
<em><u>Substitute eqn 1 in eqn 2</u></em>
6a + 3.50(125 - a) = 550
6a + 437.5 - 3.50a = 550
2.5a = 112.5
<h3>a = 45</h3>
<em><u>Substitute a = 45 in eqn 1</u></em>
c = 125 - 45
<h3>c = 80</h3>
Thus 45 adult tickets and 80 children tickets were sold
5 is 1/40 of 200.
Therefore, 35 is 7/40 of 200.
7/40 = (17.5)/100. Therefore, 35 is 17.5% of 200.
----------------------------------------
To make life easier. Just say that 35/200 =17.5/100.
So 35 is 17.5% of 200.
