Scott and Isaac went to the school carnival. Scott ride on 5 rides and played 4 games. Isaac rode on 7 rides played 2 games. If
BlackZzzverrR [31]

Answer:

The cost of the rides are 3 tickets

And 1 ticket per game

The ride and game cost 3 tickets and 1 ticket for each respectively.

Step-by-step explanation:

Step 1 of 5

Let <em>a</em> be the number of tickets per ride costs. And <em>b</em> be the number of tickets per game costs.Thus from the given, we get the equations. For Scott, <em>5a+4b=19</em>    For Isaac,  <em>7a​+2b=23</em>

Step 2 of 5

Multiplying the equation 2 by 2, we get  ​<em>5a+4b=19→1</em>  <em>14a+4b=46→2​</em>

<em>Step 3 of 5</em>

<em>By subtracting both the equations, we get </em>

<em>(−)​5a+4b=1914a+4b=46​          </em>

<em>_____________         </em>

<em>−9a      =−27                  </em>

<em>  ​a=−27−9⇒a=3​</em>

Step 4 of 5

<em>Substituting the above value in the equation 1, we get​5(3)+4b=1915+4b=194b=19−154b=4b=44⇒b=1​</em>

<em>Step 5 of 5 </em>

<em>The solution is (3,1).The cost of the rides is 3 tickets per ride.The cost of the games is 1 ticket per game.</em>

<em>sorry its really confusing this how I was taught tho. </em>

Select all the pairs that could be reasonable approximations for the diameter and circumference of a circle. * 1 point A. 5 mete
stira [4]

Answer:

B. 19 inches and 60 inches.

Step-by-step explanation:

Required

Select matching pairs

Represent diameter with D and Circumference with C

C is calculated as:

C = \pi D

Where

\pi = 3.142

A. D = 5m; C = 22m

Using: C = \pi D

C = 3.142 * 5

C = 15.71

15.71 does not approximates to 22m.

Hence, the pair do not match

B. D = 19 in; C = 60 in

Using: C = \pi D

C = 3.142 * 19

C = 59.698

59.698 approximates to 60.

Hence, the pair match

C. D = 33 cm; D = 80 cm.

Using: C = \pi D

C =3.142 * 33

C =103.686

103.686 does not approximates to 22m.

Hence, the pair do not match

<em>From the analysis above, only option B matches the diameter with the circumference</em>

B(x) = 7x + 3 and h(x) = 9x - 1. <br> Find (b+h)(x)
Brilliant_brown [7]

<u>(b+h)(x)=</u><u>16x+2</u>

Since we all know the theory that shows that a(x)+b(x)=(a+b)(x), we can use that in this problem. Simply simplify the problem and divide it into 2... b(x) plus h(x). This is simple as we already know the values of these variables so just add both and the sum will be the answer to your problem.
