linear equation, variables
Step 1
Define the variables
Let
x-----> number of erasers
y-----> total cost
we know that
------> this is the linear equation that represent the situation
therefore
the answer is y = 0.84 + (0.38)x

45
Step-by-step explanation:
73+62=135
180-135=45
180 is the whole area of the triangle
Answer:
The inequality is
2 x - 6 > 6(x -2) +8
To solve the inequality we will first use distributive property with respect to multiplication over subtraction
And then bring constant on one side and variable on another side keeping the inequality maintained
2 x -6 > 6 x -12 + 8
2 x -6 > 6 x - 4
6 x - 2 x< -6+4
4 x < -2
Dividing both sides by 2
x < 
Now i will draw the graph of above function.
Answer: x = 4
Step-by-step explanation:
5x + 34 = -2(1 - 7x)
5x + 34 = -2 + 14x Multiply -2 to 1 and -7x
5x + 36 = 14x Add 2 to both sides
36 = 9x Subtract 5x to both sides
4 = x Divide 9 to both sides
