7 out of 10 would vote for Tammy so what value (x) would vote for her out of 230. Set up a proportion comparing the two.

x= # of people who vote Tammy

7 out of 10= x out of 230
7/10= x/230
cross multiply

(7*230)= (10*x)
1610= 10x
divide both sides by 10

161= x


ANSWER: 161 people in 7th grade would vote for Tammy.

Hope this helps! :)

Which line is perpendicular to the line y=-1/3x-2 and passes through point (1,4)
xxMikexx [17]

Answer:

Option 3)  y = 3x+1

Step-by-step explanation:

<u><em>Given equation is:</em></u>

y = -\frac{1}{3} x -2

Perpendicular => <u><em>It will have a slope of negative reciprocal to this slope</em></u>

So the  ⊥ line has a slope = m =  3

Now,

Point = (x,y) = (1,4)

So, x = 1, y = 4

<u><em>Putting this in slope intercept form to get b</em></u>

=> y = mx+b

=> 4 = (3)(1) + b

=> b = 4-3

=> b = 1

<u><em>Now, Putting m and b in the slope intercept form to get the required equation:</em></u>

=> y = 3x+1

75 + 120 + 90 + ∠4 = 360

<u>Step 2: Solve</u>

  1. Add:                                                                                                                   285 + ∠4 = 360
  2. [Subtraction Property of Equality] Subtract 285 on both sides:                   ∠4 = 75
