If she is making 6 costumes that need 3 7/9 yards each, the equation would be 6 x 3 7/9.
The answer to that equation would be 22 2/3.
How to get the answer:
3 x 6 = 18
7 x 6 = 42 (the seven is from the 7/9)
42/9 = 4 2/3
then add the eight teen and the 4 2/3 and you get 22 2/3.
4x+19=7x+16
4x=7x-3
-3x=3
x=1
Answer:
m(JCA)
Step-by-step explanation:
C is the central angle here (the one in between)
so it will be m(JCA) or m(ACJ)
Answer:
Step-by-step explanation:
General form of quadratic equation:
ax^2+bx+c=0
ax^2+bx=-c
To complete the square, we will divide the coefficient of x in the general quadratic equation as written above and divide by 2
I'm the question;
x^2-20x+13=0
x^2-20x=-13
The coefficient of x =-20
Divide the coefficient by 2 and square the result afterwards
-20/2= - 10
(-10)^2= 100
Add 100 to both sides of the equation
x^2-20x+100=-13+100
x^2-20x+100=87
x^2-10x-10x+100=87
x(x-10)-10(x-10)=87
(x-10)(x-10)=87
(x-10)^2=87
Answer is 10,87
