–7.5 • (–2¾) and explain how you got the answer

Answers

Answer 1

Answer:

20.625

Step-by-step explanation:

I turned 3/4 into a decimal which would be .75 and then multiplyed -7.5 times -2.75 and then when you multiply 2 negatives you get a positive and then 2.75 times 7.5 is 20.625

Answer 2
1. Negative • Negative = Positive

-7.5 • (-2 3/4) = Positive


2. Turn (-2 3/4) into an improper fraction: (- 11/4) to multiply:

-7.5 • (- 11/4) = 20.625

EXTRA: “If you want, you can turn -7.5 into a fraction too if it helps you better!”

Which property did Michaela show?
symmetric property of equality
multiplication property of equality
substitution property of equality
reflexive property of equality

Answers

The answer it’s 16 because when you supract 25 by 9 it’s will give you 16 and the p =q so q also 16
The correct answer is C) substitution property of equality.

Michaela knew that is she substituted q for p, it would still be the same equation just a different variable.

first you add 5 and 3 together and you get 8

the multiply 8 times 10

and you get 80

And lastly to check your answer you add 50+30 together and u also get 80

Answers

Answer:

17

125

Step-by-step explanation:

exterior angle is equal to sum of interior opposite angle. so

( 2x + 6 ) + ( 5x ) = ( 8x - 11 )

7x + 6 = 8x - 11

x = 17

exterior angle = ( 8 * 17 ) - 11 = 125

Your answer would be 17 and 125

On the right side of the equation, when the student combined like terms, 7x and -4x, they did not combine them correctly. Instead of combining them correctly, the student forgot to include the sign of the -4x which caused the sum of the two terms to be 11x instead of 3x. Hope this helps!

Hello I can help you what is the math question you ask so I can help you get an A

Answer:  these are in "slope-intercept form"  y = mx + b

m is the slope.  b is the y-intercept

Start with the y- intercept, the "constant" on the right side of the equation. Plot a point there on the y-axis. Then use the slope to plot another point or two to find our where to draw the line. If there is no number for m, it is an implied 1. That means from your first point, go up 1 then 1 to the right to plot the next point

Step-by-step explanation:

When the slope is a fraction, use the denominator to find out how far to go to the right.

If the slope is negative, move down first then to the right to plot the next point.
