20% of 106
= 0.20 * 106
= 21.2
21.2 = 10.6% of 21.2 / 0.106
= 200 answer
2. 56 * 0.055 / 0.35
= 8.8
3. 6.4 / 0.8 = 8
X+2y=5

Answer: (-3, 4)
x+2(0)=5
x=5
(0)+2y=5
y=5/2
-x+3y=6
Answer: x-intercept: A. y-intercept: C.
(-6,2)
Not sure, here though.
Answer:
The answer in the procedure
Step-by-step explanation:
we know that
In this problem we have
Remember that
substitute
The units digit of a two digit number is 1 less than 3 times the tens digit. if the digits are reversed, the new number is 45 more than the original number. find the number
Answer:
no solution
Step-by-step explanation:
Hi there!
We are given this system of equations:
y=-2x+5
y=-2x+20
and we want to find the solution (the point in which the lines intersect)
There are 3 ways to solve a system, but let's use substitution in this case
Both equations are set to y, so they should be equal to each other via a property known as transitivity (if a=b and b=c, then a=c)
-2x+5=-2x+20 (the same as y=y)
Now let's solve for x
add 2x to both sides
5=20
In this case, we got an untrue statement. If this happens, then the lines won't intersect.
If they won't intersect, there's <u>no solution </u>
Hope this helps!
