Answer:

You do -3- 5=-8

Step-by-step explanation:

You do -3- 5=-8

Its just like 3+5=8

But it is in negative so it would be negative 8. But this only works in addition and subtraction. In division and multiplication it is different.

Answer:

It is equal to -8 cuz...

Step-by-step explanation:

(-3) - 5 is -8 how it's cuz a negative number minus a positive number it's gonna be a negative number.

but if a positive number minus a negative number it's gonna be a positive number.

and a negative number minus a negative number it's gonna be a positive number.

The solution is Option A.

The equation which has a constant of proportionality k = 7 is 4y = 28x

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the equation be represented as A

Now , the value of A is

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

Now , the equation is

4y = 28x

On simplifying the equation , we get

Divide by 4 on both sides of the equation , we get

y = 28x/4

y = 7x

y = 7x is of the form y = kx where the value of k is 7

Therefore,  the value of k is 7

Hence , the value of proportionality constant is 7

Answer:

<A = 115 degrees, <C = 50 degrees

Step-by-step explanation:

<A+<B+<C = 180 degrees

substitute with the given values: 4x - 13 + 15 + x + 18 = 180 degrees

Solve: x = 32 degrees

Substitute back in for <A : 4(32) - 13 = 115 degrees

Substitute back in for <C: 32 + 18 = 50 degrees

Answer:liz scored better

Step-by-step explanation:

Liz scored better because how to find a percentage is dividing whatever two numbers you have by each other so it would be 47 / 50 which equals 0.94 then you times it by 100. Which would equal 94% which is better than a 92 which means Liz got the higher score

The scale factor that was used in the dilation could be 1.5 units.

Suppose a figure (pre image) is dilated (dilated image) by scale factor of k. So, if a side of the figure is of length L units, and that of its similar figure is of M units, then:

L = k × M

where 'k' will be called as scale factor.

The quantities that are squares or multiple of linear things twice grow by square of scale factor.

So area of first figure = k² × area of second figure

Similarly,

The Volume of first figure = k³ × volume of second figure.

Since the scaling is done by product of some constant, that constant is called scale factor.

Then we have:

K = 4/6

K = 2/3

K = 1.5 units.

Thus, scale factor is the ratio of the new measurement to the old measurement therefore, the scale factor that was used in the dilation could be 1.5 units.

Answer:

$315.68

Step-by-step explanation:

We would first add up all of the hours, so that would be 5.8+4.5+8 to get 18.3 hours. Since it is saying $17.25 per hour we would multiply 17.25 and 18.3 to get 315.675. But, because we are dealing with money, our answer would be rounded to the nearest hundredth. So, Mathew earned $315.68 on Friday, Saturday, and Sunday altogether.
