Step-by-step explanation:
The value of y for the system of equation is -1/2 .
<h3>What is a System of Equation ?</h3>
A system of equation is a set of equation that have common solution
The set of equation given is
3x+4y=4
2x−4y=6
To solve the system , Elimination method will be used
Add equation 1 and 2 to eliminate y
5x = 10
x = 2
Substitute the value of x in equation 1 to determine y
3x +4y = 4
6 + 4y = 4
4y = -2
y = -1/2
Therefore the value of y for the system of equation is -1/2 .

Answer:
<h2>C. 3x + 80 + 2x = 180</h2>
Step-by-step explanation:
The straight line creates an angle of 180 °.
Therefore from the picture we have the equation:
3x + 80 + 2x = 180 <em>subtract 80 from both sides</em>
5x = 100 <em>divide both sides by 5</em>
x = 20
Answer: 258023743333miles³
Step-by-step explanation:
Volume of a sphere = 4/3πr³.
where,
π = 3.14
r = radius = 3950
Volume of a sphere = 4/3πr³.
= 4/3 × 3.14 × 3950³
= 4/3 × 3.14 × 61629875000
= 258023743333miles³
The volume of our planet if we assume that it is a sphere with the radius 3,950miles will be 258023743333miles³
Answer:
44 marbles.
Step-by-step explanation:
Each received 6 marbles so that is a total of 6*7 = 42 marbles.
