13b+6c
a = 6b = 9a + b = 6 + 9 = 15
Set it up like this: B+9=8+6B+9=14B=5
= a + b - 2
The answer is 144. The compound operator for (a) and (b) in each pair is a * (a+b). For 9 and 7, this is 9 x (9+7) = 9 x 16 = 144.
b = 6
a = 6b = 9a + b = 6 + 9 = 15
It is b + 9.
Set it up like this: B+9=8+6B+9=14B=5
= a + b - 2
The answer is 144. The compound operator for (a) and (b) in each pair is a * (a+b). For 9 and 7, this is 9 x (9+7) = 9 x 16 = 144.
-3
Only when a and b have the same sign (or when a or b equals 0). Here are some examples: |2+4|=|2|+|4|--> |6|=|6|--> 6=6 TRUE |(-1)+(-3)|=|(-1)|+|(-3)|--> |(-4)|=1+3--> 4=4 TRUE |3+(-6)|=|3|+|(-6)|--> |(-3)|=3+6--> 3=9 FALSE
First, substitute the values: ( r = 9 ), ( b = 5 ), and ( g = -6 ). Calculating ( (r + b - g) ) gives ( (9 + 5 - (-6)) = 9 + 5 + 6 = 20 ). Next, calculate ( (b + g) ) as ( (5 + (-6)) = 5 - 6 = -1 ). Finally, multiply the results: ( 20 \times (-1) = -20 ).
b = 6
4+5=9
Perpendicular equation: y = ax+14 Slope of line: 2-6/1-b = -1/a Multiply both sides by 1-b: -4 = -1+b/a By trial and improvement: -4 = -1+9/-2 By trial and improvement: -4 = -1-9/2.5 Therefore: a = -2 and b = 9 or a = 2.5 and b = -9
3 times a times a times b
