Answer:

'What is the ratio of students in Mrs. Murray's class who have an older brother to the number of students who does not have older brother?'

Step-by-step explanation:

In Mrs. Murray's class, the ratio of students in the class having an older brother to the total number of students is 1 : 3.

So, we can say 3x is the number of total students in the class of Mrs. Murrays, and x students among them have an older brother.

Hence, the number of students among all who do not have an older brother is (3x - x) = 2x

Therefore, the question may be 'What is the ratio of students in Mrs. Murray's class who have an older brother to the number of students who does not have an older brother?'

The answer is x : 2x = 1 : 2 (Answer)

Answer:

  ∠A = 44°

Step-by-step explanation:

In order to find the measure of angle A, you need to know the value of the variable x. This means you need some relation that you can solve to find x.

Happily, that relation is "the sum of angles in a triangle is 180°." This means ...

  84° +(x +59)° +(x +51)° = 180°

  (2x + 194)° = 180° . . . collect terms

  2x = -14 . . . . . . . . . . divide by °, and subtract 194

  x = -7 . . . . . . . . . . . .divide by 2

Now, the measure of angle A is ...

  ∠A = (x +51)° = (-7 +51)°

  ∠A = 44°

What is solution to this equation 4x=124
kkurt [141]

4x= 124

divide both sides by 4 to get x by itself

4x/4= 124/4

Cross out 4 and 4, divide by 4 and then becomes 1*1*x= x

124/4

12/4= 3

4/4= 1

Answer: x= 31

What is the equation of this line in standard form
Yuri [45]

Line joining (-3, -1) and (1/2, 2)

Point point form for a line is

(c-a)(y-b) = (d-b)(x-a)

(1/2 - - 3)(y - -1) = (2 - -1)(x - -3)

(7/2)(y+1)=3(x+3)

7(y+1)=6(x+3)

7 - 6(3) = 6x - 7y

6x - 7y = -11

Answer: second choice, 6x - 7y = -11

Ok I'm doing home work and need to show why 1/2 of 60 is not the same as 1/2 of 24 please help! It will give you 24 points.
Tems11 [23]
Simple,

1/2 of 60

re-write it as 0.5 of 60 aka 0.5*60

which is 0.5*60=30

Do the same with 1/2 of 24.

0.5 of 24

0.5*24=12.

Thus, it's not the same because they are different numbers and different number give you different answers.
