Answer: 4 x (8 + 5) = (4 x 8) + (4 x 5)

Step-by-step explanation:

multiply the 4 by what is in the ( )

4x8 = 32

4x5= 20

so it equals what is on the other side (in the blanks, you just plug in the 8 and 5)

so it would be

4 x (8 + 5) = (4 x 8) + (4 x 5)

The measure of the supplement of an angle is twice the measure of the angle. What is the measure of each angle?​

Answers

Answer:

120° and  60°

Step-by-step explanation:

Suplementary angles sum 180°

then:

a + b = 180°

b = 2a

then:

a + 2a = 180°

3a = 180°

a = 180/3

a = 60°

b = 2a

b = 2*60

b = 120°

Check:

120° + 60° = 180°

Find the slope of 10y = 7x + 5.
Round to the third.

Answers

Answer:

0.7

Step-by-step explanation:

10y = 7x + 5

Divide both sides by 10.

y = 7x/10 + 5/10

y = 0.7x + 0.5

On a straight line of the form y = kx + m, k is the slope of the line.

In our line, y = 0.7x + 0.5, k is 0.7. Thus, the slope of our function is 0.7

hand. Each is given a plot which is 9x11
feet in size. What is the total area of the
field?

Answers

Answer:

594 square feet

Step-by-step explanation:

Area of a rectangle is length times width. We can find the area of each workers plot by multiplying 9 and 11 to get 99 sq feet. There is six workers, and therefore six plots of land, so we'd take our 99 sq feet and count that six times to get 594 square feet.

Answer:

Scientists were monitoring the temperature of a solution. It began at 63°F, and the temperature changed by 8°F over the course of 6 hours.

The final temperature of the solution was a minimum of __°f and a maximum of __°f

Answers

Step-by-step explanation: The 6 hours is unnecessary info. 63-8=55 and 63+8=71.

The final temperature have the minimum should be 55 and the maximum should be 71.

Calculation of the minimum & maximum:

Since It began at 63°F, and the temperature changed by 8°F over the course of 6 hours.

So here the minimum should be

= 63-8

= 55

Answer:

33. D.1/3

34. D. y= x+4

35. Slope= -2/3 Y-intercept= -6

Step-by-step explanation:

For number 33. D. 1/3 is the correct answer.

Start at the point (0,2) Then, Go up 1 and Right 3.

As a result, you land in the point (3,3) This proves that the slope is 1/3.

Note: the line is increasing and going upwards, so the slope is positive.

For number 34. D. y=x+4 is the correct answer.

When writing an equation of a line, the correct format is y=mx+b. We are given both m and b. So all we have to do is plug these values into the equation y=mx+b. As a result, we get y=1x+4, which also means y=x+4

For number 35. The Correct answer is: Slope= -2/3 Y-intercept= -6

For this question I can't see all the answer choices but I know that the  Slope is -2/3  and the Y-intercept is -6. Here's why: First you need to transform the equation 2x+3y=-18 into y=mx+b format. To do this, subtract -2x from both sides of the equation and you are left with 3y=-18-2x. You can flip -18 and -2x which makes the equation 3y=-2x-18. The next step is to divide both sides of the equation by 3, which gives you y=-2/3x-6. This means Slope= -2/3 and Y-intercept= -6

Find two fracrions in between 2/7 and 3/7 whose numerator and denominator are whole numbers

Answers

Answer:

7/21 and 8/21

EASY MATH QUESTION! WILL GIVE BRAINLIEST! (MUST EXPLAIN HOW YOU GOT YOUR ANSWER!) By the end of the first quarter of a football game, Gary had gained 42 yards and had lost 9 yards. Gary lost an additional 18 yards and gained 58 yards in the second quarter. Write an equation to represent his total yardage for the first half of the game.

Answers

Answer:

+73 yards.

Step-by-step explanation:

Since we have the first two quarters, we can simply work out the yardage for each game and add them together to get the total.

42-9 = 33 (first game)

58-18 = 40 (second game)

Therefore his total yardage was +73.

42-9-18+58 = 73.

O 1) -6
2) -3
3) 3
4) 6

Answers

Answer:

f(-2) = - 8

Step-by-step explanation:

f(x) = 3x - 2

In order to find f(-2) , substitute the value of x that's - 2 into f (x) that is for every x in f (x) replace it with - 2

So we have

f(-2) = 3(-2) - 2

= - 6 - 2
