Answer:
0.25
Step-by-step explanation:
The fraction is 18/72. The decimal is different. If you divide 72 by 18, you get 4. That tells you how it is in a quarter, aka four pieces. Divide 100 by 4, you get 25. That’s why the answer is 0.25
Your graph should look exactly like the one below.
y = x + 2 (Black)
x + y = 3 (Red)
Now the solution is found in the intersection of the points, which is (0.5,2.5)
Verify:
y = x + 2
2.5 = 0.5 + 2
2.5 = 2.5 (correct)

90 = 20 + 70.....GCF of 20 and 70 is 10
90 = 10(2 + 7) <==
can u write another expression using a different common factor...yes
90 = 20 + 70.....common factor is 5
90 = 5(4 + 14) <==
Step-by-step explanation:
There are 13 numbers here:
30, 30, 31, 32, 42, 49, 58, 58, 67, 67, 69, 78, 90.
The median number is the 7th number, which is 58.
Answer:
discriminant of the quadratic equation is -16, The resulting number is less than zero so there are no real number solutions. Hope its Helps:):)
Step-by-step explanation:
Given : he quadratic equation −1 = 5x² −2x.
To find : What is the value of the discriminant .
Solution : We have given that −1 = 5x² −2x.
−1 = 5x² −2x.
On adding by 1 both sides
0 = 5x² −2x +1
On switching sides
5x² −2x +1 = 0
Compare it standard form of quadratic equation ax² +bx +c = 0.
Here, a = 5, b= -2, c = 1
By Discriminant formula:
D =
Substituting the values
D = .
D = 4 - 20
D = -16.
Therefore, discriminant of the quadratic equation is -16, The resulting number is less than zero so there are no real number solutions.
