If you would like to solve the following system of equations, you can do this like this:
y = - 2 * x + 7
y = 1/3 * x
____________
1/3 * x = - 2 * x + 7
1/3 * x + 2 * x = 7
1/3 * x + 6/3 * x = 7
7/3 * x = 7 /*3/7
x = 7 * 3 / 7
x = 3
y = 1/3 * x = 1/3 * 3 = 1
The correct result would be: x = 3 and y = 1.
Answer:
58 %
Step-by-step explanation:
So 18 % of the beads are green and 40 are purple add those and you get 58
1) factor the denominators: 2b/(b-1)2 - 2/ (b-1)2
2) MAKE SURE YOU HAVE A COMMON DENOMINATOR
3) combine the numerators: 2b-2/(b-1)2
4) distribute 2 from numerator: 2(b-1)/(b-1)2
5) simplify; answer is 2/(b-1)
Answer:

Step-by-step explanation:
Given:
Length of a rectangle solid = 3 m
Width of a rectangle solid = 0.6 m
Height of a rectangle solid = 0.4 m
To find: Volume of the solid
Solution:
Volume of the solid = length × breadth × height

So, the number of cubic meters in the volume of the solid is
For a question like this you need to find the surface area
The formula is :
b x w x h (base x width x height)
So you multiply 3 1/2 x 6 x 5 1/2 = 22.5
