In commutative property , we can add numbers in any order.

Here we are given with fractions

We can add or subtract fractions in any order

-\frac{7}{16} -\frac{1}{4} -\frac{5}{16}

We change the order of fraction that has same denominator so that we can add it more easily using commutative property

-\frac{7}{16} -\frac{5}{16} -\frac{1}{4}

The first two fractions have same negative sign and common denominator

so we add it

-\frac{12}{16} -\frac{1}{4}

Simplify the fraction 12/ 16

-\frac{3}{4} -\frac{1}{4}

Add the fractions

-\frac{4}{4} = -1

A plank of wood is 220 cm long.I cut it in 14cm pieces. what lenght of wood i will have left over?
Nana76 [90]

The required Length is 10cm.

What is length?

  • Length is a measure of distance. In the International System of Amounts, length is a volume with dimension distance. In utmost systems of dimension a base unit for length is chosen, from which all other units are deduced.
  • Length is generally understood to mean the most extended dimension of a fixed object. still, this isn't always the case and may depend on the position the object is in.
  • Varied terms for the length of a fixed object are used, and these include height, which is the perpendicular length or perpendicular extent, and range, breadth, or depth. Height is used when there's a base from which perpendicular measures can be taken. range or breadth generally relates to a shorter dimension when the length is the longest one.

220 / 14 gives us 15.

You have to understand that this means 15 whole 14 cm pieces and a Length of 1 piece.

thus 14 * 15 = 210

So 220- 210 = 10

where you know 220- 210 is< 15

Hence, The correct Length is 10cm.

Grace is an hourly employee, and the line that models her total pay in dollars
tresset_1 [31]

Answer: Hello mate!

if x is the amount of hours worked, 45 is the slope and the y intercept is 35.

A linear equation has the form of y = ax + b, where a is the slope and b is the y-intercept, then the equation that we have is:

y = 45*x + 35

this means that she wins $45 per hour, and has a plane amount of $35, indiferent of the amount of hours worked.

Then the correct answer is

C) Grace's wage is $45 an hour, and it appears that she received a  signing bonus of $35.
