Answer:
<h3>x = 22/7</h3>
Step-by-step explanation:
22x + 1 = 8
Send 1 to the right side of the equation
22x = 8 - 1
22x = 7
Divide both sides by 22
x = 7/22
Hope this helps you
(8*4)xy/ (8*3)yz= 4x/3z
Break apart the each expression to its simpler parts. The 8s cross each other out and you have 4xy/3yz left. Then you cancel the variables that match. The only ones are the ys. Hence the answer is what you have left over and cannot cancel out or reduce

Answer:
c. 9 inches
Plates and clocks are examples of circles.
Set the compass so that it is 6 inches wide. Place the needle on the paper and twist the top of the compass so that the circle is evenly drawn.
3 are left.
3/7 means there were 7 slices, but it's missing 4 slices. (Eaten)
i hope this helps :)
The equation -3=x^2+4x+1 can be rearranged into x^2+4x+4=0, you should be able recognise that this is an equation of the form ax^2+bx+c (where a, b, and c are constants). The question tells you that the discriminant of an equation of form ax^2+bx+c is equal to b^2-4ac, therefore after rearranging the equation you simply substitute the numbers in:
a=1 b=4 c=4
b^2-4ac=(4)^2-4x(1)x(4)=16-16=0
Therefore the discriminant value is 0.
To determine the amount of real solutions an equation has you look at the discriminant, if the discriminant is less than 0 there are no real solutions, if the discriminant is equal to 0 there is one solution, and if the discriminant is more than 0 there are 2 solutions. therefore as our discriminant is equal to - there is 1 real solution.
