X the 1st table
y the second
z the third
The equation is : x+y+z =16.9
But we know (given) that x=2y & z=(1/3)y
Calculate everything in term of x:
x= 2y==> x/2 =y
z=(1/3)y ==> & since y=x/2 then z= (1/3)(x/2)==> z=x/6; y=5.07 & z =1.69
x + x/2 + x/6 = 16.9===>1.666x = 16.9===> x= 10.14
So the angle A on the first diamond corresponds with angle Q, angle B with angle S, angle C with angle R, and angle D with angle P. So if angle D correspond (equals) angle P then x+34=97 and if angle R corresponds with C then 3y-13=83. From there just do some basic algebra to find the x and y values.
To see if 8 is the solution to the equation, 3 (x - 2) + 4 = 22, you must replace x with 8 and solve using the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction) REMEMBER: IF NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS . If the sides are equal to each other then 8 IS a solution.
3(8 - 2) + 4 = 22
Parentheses...
3(8 - 2) + 4 = 22
8 - 2 <<<In the parentheses so you must solve first
6
so...
3(6) + 4 = 22
Multiplication...
3(6) + 4 = 22
3 * 6
18
so..
18 + 4 = 22
Addition...
18 + 4 = 22
18 + 4
22
so...
22 = 22
Are they equal to each other? YES!!!
8 is a solution to the equation 3 (x - 2) + 4 = 22

Step-by-step explanation:
fa - g = a
fa - a = g
a(f - 1) = g
a = g/(f - 1)
Step-by-step explanation:
So first you want to multiply the percentage of the yellow balls by three to get the amount of "300%" which is 300 balls. Munising 100 by 40, you get 60% is white. So multiply that by three also. So for Yellow, you have 120 balls, and for white, you have 180. So you take 120 and take 20% of it, and it would give us 24. You take the 180, and that one gives us 144. So if you add 144 and 24, Sally's team found 168 balls out of 300.
hope this helps
