Answer:
Austin earned a higher score
Step-by-step explanation:
47/50 (Austin's score) = 94/100 (denominator is now 100) = 94% (converted to percentage) > 92% (Marty's score)
Hope this helps!
Answer:
x = StartFraction negative
(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction
Step-by-step explanation:
0 = – 3x2 – 2x + 6
It can still be written as
– 3x2 – 2x + 6 =0
Quadratic formula=
-b+or-√b^2-4ac/2a
Where
a=-3
b=-2
c=6
x= -(-2)+ or-√(-2)^2-4(-3)(6)/2(-3)
x = StartFraction negative
(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction
Answer:
x = 13 1/2 or 27/2
Step-by-step explanation:
1st Add 2 to both sides: 2/3x-2+2=7+2
2nd Simplify: 2/3x = 9
3rd Multiply both sides by 3: 3*2/3x=9*3
4th Simplify: 2x=27
5th Divide both sides by 2: 2x÷2=27÷2
6th Simplify: x = 13 1/2 or 27/2
Answer:
B
Step-by-step explanation:
Here, we want to know at what values of b does the equation becomes not solvable
Now looking at the left hand side, we have;
2/(3-5bx) and also the right hand side bx + 1/3
For this expression if we insert b = 0, then automatically x cancels out on both sides of the equation and we shall be left with nothing to solve
Answer:
y = 4
Step-by-step explanation:
We have,
5x + 3y = 12 ....(1)
and
-5x + 4y = 16 ....(2)
Adding equation (1) and (2),
0 + 7y = 28
or
7y = 28
Dividing both sides by 7,
y = 4
So, the value of y = 4.
