Multiplication:
10* -4 / 3*9 = -40 / 27
Addition:
-40 / 27 + 7/6 find common denominator 108
-40*4 / 27*4 + 7*18 / 6*18
-160 / 108 + 126 / 108
-34 / 108
-17 / 54
Subtract:
-17 / 54 - 2/5 common denominator 270
17*5 / 54*5 - 2*54 / 5*54
-85 / 270 - 108 / 270
-193 / 270
-193/ 270 = -0.7148
-8 / 15 = -0.7148 :)
M AR = 55°
m RB = 66°
Like AB=8 m =RS →m RS = m AB
m AB = m AR + m RB
m AB = 55° + 66°
m AB = 121°
m RS = m AB
M RS = 121°
Answer: m RS is 121°
The equation is:
3.85g + 6.42q = 65
The reason why it looks like that is because he spent $65 in total. And it’s $3.85 per one gallon and $6.41 per one quart.
Answer: 2 1/10
Step-by-step explanation:
21 : 10
Step 1: to write as a fraction= 21/10
2 1/10
To find value of n, we have to have only one n of the RHS.
To do this, we can multiply both sides by 8
/*8
Now we can divide both sides by -5
/ :(-5)
Result is -64
