Answer: It’s 1
Explanation: it’s 1
Answer:
To determine the nature of roots of quadratic equations (in the form ax^2 + bx +c=0) , we need to calculate the discriminant, which is b^2 - 4 a c. When discriminant is greater than zero, the roots are unequal and real. When discriminant is equal to zero, the roots are equal and real.
Divide 12 by all of the ingredients then multiply them by 18
Answer:
48 sweets
Step-by-step explanation:
5:2:4
Sarah: 5
Natasha:2
Richard:4
To find out how many sweets Richard got, we need to use 60 as the lcm. Since, we have a definite constant of 60 we need to divide it by the presiding ratio.
60/5 = 12
That means for a ratio of 1, everyone in the group recieves 12.
Now, we plug it in for each of the members.
5x = Sarah
2x = Natasha
4x = Richard
Sarah = 60 sweets
Natasha = 24 sweets
Richard = 48 sweets
Answer:
4
Step-by-step explanation:
If x is the third number, then x−1 and x−2 are the second and first numbers.
10(x−2) + 10(x−1) = 10 + 10x
x − 2 + x − 1 = 1 + x
2x − 3 = 1 + x
x = 4
