Answer:
15/2
Step-by-step explanation:
Subtract 5x from both sides of the equation to find out.
5x +3x -5x = 5x +15/2 -5x . . . . . . subtract 5x
3x = 15/2 . . . . . . . . . . . . . . . . . . . . collect terms
The required value of 3x is 15/2.
Answer:
Weight of the solution = 250 grams
Step-by-step explanation:
1) Consider the weight of solution as x grams.
32 % solution = 80 grams salt
32% of x = 80
(32/100)*x = 80
Solving for x:
x = (80*100) / 32
x = 250 grams

Answer:
Step-by-step explanation:
length=1 m
base of triangle=10 m
height=5m
volume= 1/2×10×5×1=25 m cube.
slant height l=√(5²+5²)=√50=5√2
slant surface area=2[5√2×1]=10√2
area of front and back=2×1/2(10×5)=50
total surface area=50+10√2≈50+14.14≈64.14 m²
