77+95+84+69=325 
325/4=81.25
This is her average right now 
A)77+95+84+69+85=410
410/5=82

B)77+95+84+69+90=415
415/5=83
So B would work too

C)77+95+84+69+87=412
412/5=82.4
(I just chose a number higher than 85)

D)77+95+69+84+95=420
420/5=84
(I just chose a number higher than 92)

A. would be your answer because she at least needs to make a 85 to get a 82 average.

a sixth grade class has 12 boys and 24 girls consider this statement: <br />for every two boys there are 4 girls do you ag
Nitella [24]
So the ratio of boys to girls is 12:24.. now, is that an equivalent ratio as 2 boys for 4 girls? or 2:4?  let's see.

\bf \cfrac{boys}{girls}\qquad 12:24\qquad \cfrac{12}{24}\implies \boxed{\cfrac{1}{2}}
\\\\\\
\cfrac{boys}{girls}\qquad 2:4\qquad \cfrac{2}{4}\implies \boxed{\cfrac{1}{2}}

you could start simplifying the 12/24 fraction by dividing by some common multiple, say 2, and get 6/12, then divide by 3 and get 2/4  and stop there.

then you'll notice that 12/24 is really 2/4 in disguise.

Marrrta [24]

Alright, lets get started.

Maria hiked the 5 mile Mountain Trail a number of times and she hiked the 10 mile canal trail several times.

x times she hiked 5 mile mountain.

So, number of mils she hiked for 5 miles will be = 5 x

Similarly,

y times she hiked 10 mile canal,

So, number of miles she hiked for canal = 10 y

So, total number of miles she hiked = 5 x +10 y

But as per question given,  she had a total of 90 miles

It means

5x + 10 y = 90

Dividing this equation with 5

x + 2 y = 18

So, the equation is x + 2 y = 18 :   Answer

Hope it will help :)

I need help really badly please
Stolb23 [73]

Answer:

  y = 26

Step-by-step explanation:

The angles of a linear pair total 180°.

__

  (2y +1)° +(5y -3)° = 180° . . . . the sum of the angles is 180°

  7y -2 = 180 . . . . . . divide by °, collect terms

  7y = 182 . . . . . . . . add 2

  y = 26 . . . . . . . . . divide by 7

_____

<em>Additional comment</em>

The angle measures are (2(26) +1)° = 53°, and (5(26) -3)° = 127°. These total 180°, as they should.
