Answer:
Step-by-step explanation:
Let the number of the problems the team could solve before is x.
<u>Then we have:</u>
- x + 40% = 42
- 1.4x = 42
- x = 42/1.4
- x = 30
They were able to solve 30 problems before the new mathletes joined
Connected cellular because you make 800 a week but with the other you only make 700
Step-by-step explanation:
So you add one over the other
3x-2y=7
-3x+5y=5
=
3y=12
Then you divide 3 from both sides
(3y)/3=12/3
y=4
Then you substitute the y=4 in to the equation of your choice
3x-2(4)=7
3x-8=7
3x-8=7
+8 +8
3x=15
x=5
Answer:
B divides A and B in the ratio of 1:2 internally.
Use this formula :
B (X,Y)=(m1x2+m2x1/m1+m2,m1y2+m2y1/m1+m2)
