8/14 boys, 6/14 girls which means 4/7 boys and 3/7 girls
Answer:
4+6i
Step-by-step explanation:
Distribute the 2 to the 3i
You get 6i, you can't add 4 to 6i because 4 is real and 6i is imaginary.
It's a complex imaginary number
Answer:32
Step-by-step explanation:
80x.40=32
Isiah determined that 5a2 is the GCF of the polynomial a^3 – 25a^2b^5 – 35b^4-<u>No,Isiah is not correct if he states that that 5a2 is the GCF of the polynomial</u>
Step-by-step explanation:
Firstly ,we divide each term by the GCF and if the term does not divide evenly, then it is not valid
so,
5a^2 divide by a^3
we see that we cannot divide 5a^2 by a^3 because firstly the power is higher and then there is no 5 number.Thus it is not the GCF
The GCF of the coefficients is 1, and there are no common variables among all three terms of the polynomial.
Also we find that 5b^4 is a factor of -25a^2b^5 and -35b^4, but not a3. Additionally, a2 is a factor of a3 and -25a^2b^5, but not -35b^4.
A=number of adult tickets
s=number of student tickets
number of adult tickets was 120 less than twice student
a=-120+2s
total was 840
840=a+s
subsitute -120+2s for a
840=-120+2s+s
840=-120+3s
add 120 to both sides
960=3s
divide both sides by 3
320=s
sub back
a=-120+2s
a=-120+2(320)
a=-120+640
a=520
520 adult tickets
320 student tickets
