7/30+9/20 what is the answer pls hurry im so confused
Svetradugi [14.3K]

Here is your answer:

  • \frac{7}{30} + \frac{9}{20}
  • Find common denominator:
  • 30 \times 20 = 60 /20 \times 30 = 60
  • Common denominator is 60:
  • \frac{7}{30} + \frac{9}{20} = \frac{140}{60} + \frac{270}{60}
  • 140 + 270 = 410
  • = \frac{410}{60}
  • \frac{410}{60} \div 2 = \frac{205}{30} \div 5 = \frac{41}{6}
  • = \frac{41}{6} or 6\frac{5}{6}

Hope this helps!

Graph 3x + 4y = -10
cricket20 [7]
First, isolate y on one side to find some information about the graph. 

3x+4y=-10 
4y=-10-3x
y=(-10-3x)/4 

Now find out the x and y intercepts of this equation;

(0)=(-10-3x)/4 
4x0=-10-3x 
0=-10-3x 
3x=-10 
x=-10/3 or -3.3333 (x-intercept) 

y=(-10-3(0))/4
4y=-10 
y=-10/4 or -5/2 = -2.5 (y-intercept) 

Plot these points onto your graph and connect the lines. 

I have attached a graph below, I'm sorry I couldn't do it on paper. 

Hope I helped :)
