astrophysicist Neil deGrasse Tyson once commented somehow its ok for people to chuckle about not being good at math. Yet if I said I never learned to read they'd say I was an illiterate dolt he was referring to the notion that it has become socially acceptable for people to say they are bad at math but it is unacceptable to say they are bad at reading

Answer:

4 students had snickers

Step-by-step explanation:

$6.80-$4.80=$2.00

0.30x16=$4.80

$0.30x4=$2.00

$4.80+$2.00=$6.80

Step-by-step explanation:

there is no big "trick" involved.

you just need to do the multiplication and then move the terms into the right spot, so that the x-, y- and constant terms are in the same place as the generic Ax + By = C

y + 5 = 4(x + 1)

y + 5 = 4x + 4

-4x + y = -1

or (after multiplying both sides by -1)

4x - y = 1

yes, B = 1 (or -1), so you could write 1y (or -1y) instead of only y (or -y).

but nobody does that.

Answer:

8

Step-by-step explanation:

6= 14.8 cent an ounce

8= 13 cent an ounce

10= 16.9 cent an ounce

32=14.9 cent an ounce

therefore 8 is the best deal

Answer:

Midsegment of a triangle is half the length of the third side in order to fill in the triangle.

So, the perimeter of a midsegment tirangle is half the perimeter of QRS.

Perimeter of QRS:

For finding out it's perimeter sum up all the sides while adding alike variables together.

=> (2x + 5) + (3x - 1) + (5x)

= 2x + 3x + 5x + 5 - 1

= 10x + 4

Perimeter of mid-segment triangle:

Perimeter of QRS divided by 2

[tex] \implies \mathsf{ \frac{10x + 4}{2} }[/tex]

= 5x + 2

Answer: Graph it!!!!!!!!!!!!!!!!!!!!!!

Answer:

True, the given lengths do form a right triangle.

The answer is Elisa's Hourly rate

Step-by-step explanation:

Rida and Elisa are each paid by the hour.

Rida worked 5 1/2 hours and earned 77.

5 1/2 = 11/2 = 5.5 Hours

Rida earned 77 in 5.5 hours

Elisa worked 3 3/4 hours and earned 60.

3 3/4 = 15/4 = 3.75 Hours

Elisa earned 60 in 3.75 hours

Elisa earns more than in less time as compared to Rida

so Elisa's hourly rate is greater than Rida

Thus, The answer is Elisa's Hourly rate

-TheUnknownScientist 72

Step-by-step explanation:

we find out by checking how much they got for 1 hour.

so, 77 earned in 5 1/2 hours. how much in only 1 hour ?

77 / (5 1/2) = 77 / 11/2 = 77 × 2/11 = 7×2 = 14

and 60 earned in 3 3/4 hours. how much in 1 hour ?

60 / (3 3/4) = 60 / 15/4 = 60 × 4/15 = 4×4 = 16

so Elisa's hourly rate is greater.

The graph in the given diagram where 1 < x < 6 is: decreasing.

In a graphed function, if the line of the graph within a given interval slopes downwards from your left to the right, it means the graph is decreasing.

Taking a look at the given graph shown in the diagram below, the line of the graph within the interval 1 < x < 6, slopes downwards. Therefore, the graph is decreasing.

alternate form [tex]\frac{2}{5} , 4times 10^{-1}[/tex]

Answer: 25% of 60 is 15, 10% of 40 is 4, 12% of 450 is 54, and 20% of 225 is 45.

So a is 15, b is 4, d is 450, and c is 225.

The slope represent that the y changes with respect to x at a  constant rate, while the y intercept shows the initial value of y.

A linear equation is in the form:

y = mx + b;

y, x are variables, m is the rate of change of y with respect to x, b is the initial value of y.

Therefore the slope represent that the y changes with respect to x at a  constant rate, while the y intercept shows the initial value of y.

Answer:

Line m is not parallel to Line n.

Line m is perpendicular to Line k

Step-by-step explanation:

1. Calculate slopes of n and m. N = -2 and M = -7/4. The two slopes aren't the same thus they are not parallel

2. Slope of m = -7/4 and k = 4/7. By definition of perpendicular these two fit the description. (to be perpendicular, k = -1/m

1. To find the sum of two integers with like signs simply add them and keep the sign same as integers

for example:

[tex]2 + 3 = 5 \\ - 2 + ( - 3) = - 5[/tex]

2. To find the sum of the integers with unlike signs just subtract them and then keep the sign of the bigger integer.

For example:

[tex] - 3 + 5 = 2 \\ - 5 + 3 = - 2[/tex]
