Answer:
x=13
y= -9
(13, -9)
Step-by-step explanation:
If we are solving using the substitution method, we can take the first equation and set it to y so y=4-x.
Then, we can take that equation and plug it into the bottom one so
3x+4(4-x)=3
Simplify:
3x+16-4x=3
-x=-13
x=13
We can then plug 13 into any of the two given equations (I am just going to plug it into the top one)
So, 13+y=4 which y= -9
Answer:
Option D is the Answer
Step-by-step explanation:
Given : Benni wants to divide 48.6 by 0.7.
To find : In order to estimate the quotient, which is the best expression to use?
Solution :
In order to estimate i.e. an approximate calculation we round the numbers,
48.6 as tenth place is > 5 then it round completely
0.7 as tenth place is > 5 then it round completely
So the estimated expression is given by,
Therefore, option D is correct.
Answer:
the answer is D 6,280
Step-by-step explanation:
Since it says difference you subtract, 86 is below sea level so it'd be -86
the equation would be 6,194 - (-86)
6,194+ 86 = 6,280
Answer:
7=9x+10+x+3
Step-by-step explanation:7=10x+13
10x=20=10x/10=20/10=2 2 is the answer
Answer:
One Solution
Step-by-step explanation:
Once you solve the equation, you get 0 which satisfies for X, therefore it has a solution.
