After solving simultaneously we found the values for x and y are

2.76 and 5.65 respectively

<h3>Simultaneous Equations</h3>

We have the following two expressions

7x – 2y = 34 --------1

3x + 5y = -3 ---------2

Multiply 1 by eqn 5 and eqn 2 by 2

35x - 10y = 170-------3

6x + 10y = -6 ----------4

subtracting 4 from 3 we have

29 x= 164

divide both sides by 29

x = 164/29

x = 5.65

Put x = 5.65 in eqn 1 to find y

7*5.65 – 2y = 34

39.55 - 2y = 34

39.55-34 = 2y

5.55 = 2y

divide both sides by 2

x = 5.55/2

x = 2.76

What is 2(W+5)+4W=4(3+W)
yulyashka [42]
You will need to use the distributive property of multiplication over addition to solve this problem.
2w+10+4w=12+w
combine like terms using the associative property
6w+10=12+w
solve the equation
6w+10-10=12-10+w
6w÷6=2+w÷6
w=2+w/6

A cylinder soup has a radius of 1,6 in and is 5/7 in. tall what is the volume
nata0808 [166]

Answer:

V=0.0623\ inch^3

Step-by-step explanation:

Given that,

The radius of cylinder, r = 1/6 inch

The height of the cylinder, h = 5/7 inch

We need to find the volume of the cylinder. The formula for the volume of a cylinder is given by :

V=\pi r^2 h\\\\=3.14\times (\dfrac{1}{6})^2\times \dfrac{5}{7}\\\\V=0.0623\ inch^3

So, the volume of the cylinder is equal to 0.0623\ inch^3.
