Answer:

69

Step-by-step explanation:

First of all you have to follow BEDMAS:

32 / 2 x 4 + 5 (do division first)

16 x 4 + 5 (do multiplication)

64 + 5 (do addition)

= <em>69 </em>

A shop has a sale that offers 20% of all prices.
Nana76 [90]
<h2>Greetings!</h2>

Answer:

40% reduction

Step-by-step explanation:

To answert this, we need to find how much of the price is each percentage. This can be found my subtracting the percent from 100:

Sale price: 100 - 20 = 80

Last day price: 100 - 25 = 75

Now we need to multiply these two values together, remembering to divide both numbers by 100 first:

80 ÷ 100 = 0.8

75 ÷ 100 = 0.75

0.8 * 0.75 = 0.6

Then multiply by 100 to find the percentage:

0.6 * 100 = 60

60% is the end price, but to find the overall reduction we need to subtract this value from 100:

100 - 60 = 40

So there was a 40% reduction on the price.

r-ruslan [8.4K]

Answer:

<em>The polygon area is </em>51.5 U^{2}<em />

Step-by-step explanation:

Points:

(2,7), (8,2), (6,11), (6,5), (11,6)

1. The area of the polygon could be calculate with the eqation:

A=\frac{1}{2}\left[\begin{array}{ccc}x_{1} &y_{1}\\x_{2} &y_{2}\\x_{3} &y_{3}\\x_{4} &y_{4}\\x_{5} &y_{5}\end{array}\right]

2. Replace the coordinates in equation for A:

A=\frac{1}{2}\left[\begin{array}{ccc}2&7}\\8&2\\6&11\\6&5\\11&6\end{array}\right]

3. Solve the determinant, and calculate A:

A=\frac{1}{2}\left[\begin{array}{ccc}2&7}\\8&2\\6&11\\6&5\\11&6\end{array}\right]\\A=\frac{1}{2}[(6)(7)+(11)(11)+(8)(6)+(6)(2)]-[(2)(11)+(6)(6)+(11)(2)+(8)(5)]\\A=\frac{1}{2}[42+121+48+12]-[22+36+22+40]\\A=\frac{1}{2}[223]-[120]\\\\A=\frac{1}{2}[103]=51,5 U^{2}

<em>The polygon area is </em>51.5 U^{2}<em />

Umnica [9.8K]

The equation for this problem can be written as 18x=162. X would represent the number of games bought. You do the inverse operation of multiplying by 18 to both sides and you get the answer as x=9. 9 is the number of games bought with 162 dollars.
