Answer:

It is 0.873 but rounded to hundredth is 0.87

Step-by-step explanation:

expression: (3.24-3/8+7/9-0.15) divided by 4

Solve:  (3.24+7/9-3/8-0.15) divided by 4

= (3.24+0.78-0.375-0.15) divided by 4

=3.49/4

-0.873 = 0.87 to the nearest hundred

Dvinal [7]

Answer:

Domestic Stamps: 60

Foreign Stamps: 36

Step-by-step explanation:

96 - 24 = 72

72 ÷ 2 = 36

36 + 24 = 60

d - f = 24

60 - 36 = 24

24 = 24

d + f = 96

60 + 36 = 96

96 = 96

Y = 2x <br> x + y = −6<br> the answer should be like this (x,y) or ( , )
melisa1 [442]

Answer:

(-2, -4)

Step-by-step explanation:

Given:

The system of equations to solve is given as:

y=2x\\\\x+y=-6

In order to solve this system of linear equations, we use substitution method.

In substitution method, we substitute the value of any one variable in the other equation.

So, we substitute the value of 'y' from first equation in the second equation.

This gives,

x+2x=-6\\\\3x=-6

Dividing both sides by 3, we get:

\frac{3x}{3}=\frac{-6}{3}\\\\x=-2

Now, y=2x=2\times -2=-4

Therefore, the solution is (-2, -4)

LiRa [457]

Answer:

11.67

Step-by-step explanation:

Given: Employee earn $175 for 15 hours

We know, the constant of variation means the rate of change.

To know The constant of variation, we need to find how much employee earn each hour.

∴ Constant of variation= \frac{Total\ earning}{Total\ working\ hours}

Constant of variation= \frac{175}{15}= 11.666

∴ Constant of variation= 11.67. (rounding off)
