X + y = 85
2x + 4y = 218
x = 85 - y 
<span>2(85 - y) + 4y = 218 </span>
<span>170 - 2y + 4y = 218 </span>
<span>170 + 2y = 218 </span>
<span>2y = 48 </span>
<span>y = 24 </span>
<span>x = 61</span>

Answer:

D Antenna #4

Step-by-step explanation:

As per given graph we can write the function

  • the intercept is zero, as x=0, y=0
  • at x=2, y=30  ⇒ 30= 2*15
  • at x=4, y=60 ⇒ 60= 4*15

The slope is 15, so the function is

  • y=15x

And the function for the antenna revolving at twice the rate would be

  • y=30x

Comparing data in given tables we can see it is D Antenna #4

  • x= 22 ⇒ y= 22*30= 660
  • x=24 ⇒ y= 24*30= 720

Feliz [49]

Answer:

15 goals out of 50 penalty kicks was scored by brock

Step-by-step explanation:

If Brock shoots 50 penalty kicks and the probability that he scores a penalty kick is 3/10, the number of goal brock is expected to make can be expressed as:

Number of goals scored = probability value * total penalty kicks taken

Number of goals scored = \frac{3}{10}*50

Number of goals scored = 15 goals
