Answer:
The sum of relative frequencies is equal to one, since the sum of all fractional parts must equal the whole.
Answer:
2 and -3
Step-by-step explanation:
Let the numbers be x and y ∴ 4x -2y =-16......................Eqn 1
and x+y=-1.................................Eqn 2
this ⇒x=-1-y. Substitute the value of x to be=-1 -y and putting in Eqn 1 yields the following 4(-1-y)-2y =-16 0r -4-4y-2y=-16
⇒-4-6y=-16 0r =-6y=-12 ∴y is 2
⇒ and x is -3
I can’t see the “students work”. But the answer would be 250 words in 5 minutes.
Here’s how you would set up the equation:
25x(5*2)=
So your first step would be to multiply 5 and two because they’re in parenthesis, which would be 10.
So now you have:
25x10
25 times 10 is 250.
Hope that makes sense and helps! :)
Answer:
P=2.25x-----------1
M=2.25y----------2
Step-by-step explanation:
Step one:
given data
we are told that the cost of pears= $2.25 each
and cost of mango= $2.25 each
Step two:
the chef bought x pears and y mangoes
let the total cost of pears be P
and for mango be M
P=2.25x-----------1
M=2.25y----------2
I decided to do a addition problem because based on the answer it couldn't be multiplication, subtraction, or division. Therefore, my problem would look like 15+9=24 birds in total.
