Answer:

-(-4)(-6)*3/5(10+15)

when there is a (-) in front of an expression in parentheses, change the sing of each term in the expression.

4*(-6)*3/5*(10+15)

Add the numbers (10+15)

4(-6)*3/5*25

multiplying an odd number of negative terms makes the product negative

-4*6*3/5*25

reduce the number with the greatest common factor 5

-4*6*3*5

calculate the product

solution

-360

The boundary line on the graph represents the equation 5x + 2y = 6. Write an
BartSMP [9]

Answer:

The inequality representing the shaded area is y < 3 - 2.5·x

Step-by-step explanation:

The given equation of the graph is 5·x + 2·y = 6

Therefore, we have;

2·y = 6 - 5·x

y = 6/2 - 5/2·x

y = 3 - 2.5·x

Given that the graph is represented by a shaded region on the left and lower side of a broken line, the inequality relationship for the graph is that of a lesser than area inequality with a symbol of < and the inequality for the graph can be represented as follows,

y < 3 - 2.5·x.

Alika [10]

Answer:

The Original length of the wire is 61.1 cm.

Step-by-step explanation:

Given:

l-12.5=48.6

Now it has been given that the above equation can be used to find the original length in centimeters of a wire before it was cut.

Also We need to find the original length of the wire.

From above equation we can say that;

l ⇒ Original length of the wire.

On Solving the above equation we get;

l-12.5=48.6

Now we will add both side by 12.5 using addition property of equality.

l-12.5+12.5 =48.6+12.5\\\\l =61.1\ cm

Hence the Original length of the wire is 61.1 cm.
