20% solution+70% solution=50% solution
total is 50
so the quantaties are x and 50-x (x+50-x=50)
0.2(50-x)+0.7(x)=0.4(50)
solve
distribute
10-0.2x+0.7x=20
10+0.5x=20
minus 10 both sides
0.5x=10
times 2
x=20

Answer:
Yes! (it’s making me write 20 letters so yes is ur answer ok cool)
30 has Infinite amount of multiples but a few are 60,90,120,150,180,210,240
In simpler terms multiples are what numbers go into
Answer:
x=27
Step-by-step explanation:
Solve by using similar triangles
We can see that the two triangles are similar due to the markings on angle A and they have a ratio of 10:14=5:7 or 5/7
So we can use that information to set the two sides with x equal to the ratio between the two triangles and then solve for x
x+8/2x-5=5/7 now we cross multiply
7x+56=10x-25 now subtract -7x and add 25 to both sides to get all x terms on one side
3x=81 divide by 3 to isolate x by itself and solve
x=81/3=27
x=27
