Answer:
(8,-1)
Step-by-step explanation:
Given :
To Find: solution of given system of equations.
Solution:
Equation a :
Equation b :
Substitute the value of y from equation b in equation a
y from equation b : y = 7-x
Now substitute value of y in equation a
Thus equation a becomes:
⇒ x= -1 and x = 8
Now substitute values of x in equation b to obtains values of y
⇒
for x = -1
⇒
⇒
⇒
Thus (x,y)=(-1,8)
For x =8
⇒
⇒
⇒
Thus (x,y)=(8,-1)
Hence Option A is the correct solution .
Answer:
positive; sence it's starting from the bottom and going up its positive
Hello there!
I don't know which numeral you are talking about, here is the roman numeral.
Roman Numeral: XXIV.LXV.CXXVII 24.(ignored the 0 because there is no roman numeral)65.127
If you mean't like in words: Twenty Four Zero Sixty Five One hundred Twenty Seven.
Or
Two Four Zero Six Five One Two Seven
Hope this helped!!
Let
x-------------> number of baseballs
y-------------> number of bats
we know that
x+y=100----------------> x=100-y --------------> equation 1
4.5x+20y=822 ------------------------> equation 2
<span>I substitute 1 in 2
</span>4.5*(100-y)+20y=822----------------> 450-4.5y+20y=822-----> 15.5y=372
y=372/15.5-----------> y=24
x+y=100------------> x=100-24---------> 76
the answer is
number of baseballs are 76
number of bats are 24
Since it is 1 out of 14, take 400 and divide it by 14 (400/14) which would give 28.57142857... . So round to the nearest whole number = 29. SO THE ANSWER IS “C, 29”
