Evaluate the expression. [(8 x 7) – 2): 9​
frozen [14]

Answer:

☑ Answer is 6

Step-by-step explanation:

{ \tt{ \{(8 \times 7) - 2 \} : 9}} \\  = { \tt{(56 - 2) :9 }} \\  = { \tt{54 :9 }}

» But this is a ratio, so it can be expressed in terms of fractions:

= { \tt{ \frac{54}{9} }} \\

» Divide both the denominator and numerator by 9:

{ \tt{ =  \frac{54 \div 9}{9 \div 9} }} \\  \\  = { \tt{ \frac{6}{1} }} \\  \\  = 6

A belt and a pair of pants cost $490 altogether. A bag costs twice as much
m_a_m_a [10]

Answer:

$196

Step-by-step explanation:

Lets assume,

cost of a belt = 'x'

cost of a pair of pants = 'y'

Now, According to the question;

  1. x + y = 490;
  2. cost of a bag = twice the cost of belt = 2x;
  3. cost of a pair of pants = twice the cost of bag

    ⇒ y = 2×2x ⇔ 4x

hence, by subtituting the values in equation' we get;

⇒ x + 4x = 490

⇒ 5x = 490

⇒ x = 98

So, the difference between the cost of the pair of pants and the bag ;

⇒ y - 2x

⇒ 4x - 2x

⇒ 2x = 2×98 = 196.

The sides of a triangle are x, x+7, and 2x-8. If the perimeter of the triangle is 47, what is x
kirza4 [7]

just like the previous one, we sum the sides to get the perimeter.


\bf (x)+(x+7)+(2x-8)=47\implies 4x-1=47\implies 4x=48\\\\\\x=\cfrac{48}{4}\implies x=12
