3x + 2x = -15 awnser

Eddi Din [679]3 years ago

3x+2x=-15
5x=-15
5x/5 = -15/5
x=-3
Numbers with the same variable can be combined, which would make you add 3x and 2x to give you 5x. then to get rid of the 5 in front of the x, divide BOTH sides by 5, the 5 is then divided out from the x, and -15 divided by three is -3

Option C: \frac{4}{5} is the slope of the line

Explanation:

The line passes through the points (3,-1) and (-2,-5)

We need to find the slope of the line.

The slope can be determined using the formula,

m=\frac{y_2-y_1}{x_2-x_1}

Where the coordinates (x_1,y_1) and (x_2,y_2) are (3,-1) and (-2,-5)

Let us substitute the points in the formula

Thus, we have,

m=\frac{-5-(-1)}{-2-3}

Simplifying, we get,

m=\frac{-5+1}{-2-3}

Adding the numerator and denominator, we have,

m=\frac{-4}{-5}

Cancelling the negative terms, we get,

m=\frac{4}{5}

Thus, the slope of the line is m=\frac{4}{5}

Therefore, Option C is the correct answer.

An item was sold at a loss of 20%. Had it been sold for Rs 3000more then the profit would have been 10%. What is the cost price
vagabundo [1.1K]

Answer:

Cost Price = Rs 10000

Step-by-step explanation:

Assume:

Cost of the item = x

Item was sold at a loss of 20%:

Loss = 20% of x = 0.2x

Item sold = x - 0.2x = 0.8x

Item sold at a profit of 10%:

Profit = 10% of x = 0.1x

item sold = x + 0.1x = 1.1x

Solve:

Difference = 1.1x - 0.8x = 0.3x

0.3x = Rs 3000

x = Rs 3000 ÷ 0.3

x = Rs 10000
