Answer:

  1075/42

Step-by-step explanation:

  \dfrac{250}{12}+\dfrac{100}{21}=\dfrac{250(21)+(12)100}{(12)(21)}=\dfrac{6450}{252}\\\\=\dfrac{(6)(1075)}{(6)(42)}=\boxed{\dfrac{1075}{42}}

Help me please, the answer choices are on the pic
Sati [7]

Answer:

104

Step-by-step explanation:

Let's say that the numbers are x and y. So, we know that....

x+y=186

y-x=22

Now we can use the substitution method to find the numbers. y-x=22 turns into y=22+x. And now we can substitute to the second equation into the first equation.  

x+22+x=186

2x=164

x=82

y=22+82

y=104

Our numbers are 82 and 104 and the larger integer is 104, so that's the answer.

i need with this math problem. I am confused on how to do it. If you could help me it would be great. There are 2 parts to this
Novay_Z [31]
She took a total of 60 minutes
she answered both mulitiple choice and extended response in the total time which is 60 minutes
she took 2 minutes on rach multiple choice question and 6 minutes for the extended response
let x=number of multiple choice questions
let y=number of extended response questions
we can deduce that
total time =x*2+y*6
60=2x+6y
also we can deduce
20=x+y
since 20 ia the sum of multiple choice and extended response
for part 2 we just solve the system of equations
60=2x+6y
20=x +y
lets multiply the second equation by 2 so we can get rid of x
60=2x+6y
40=2x+2y
subtracting the two equations from each other to yields
20=0 +4y
y=5
to get x we substitute in one of the equations we derived from question 1
x+y=20
substituting y for its value we get
x+5=20
x=15

Answer:

Maybe it is this answer

Step-by-step explanation:

I disagree because if both number are the same so how would they be different heights if the both triangles have the same numbers 7,5,5 and 7,5,5 so none are the same height.
