Answer:

46 weeks

Step-by-step explanation:

15*46

=690

690+345

=1035

Answer:

I think it's A. multiply the denominator by the whole number the add the numerator to the number you got. that would give you 15/4 since it's an improper fraction see how many groups of 2 is in 15 which would give you 7.

Answer:

-24

Step-by-step explanation:

absolute value of -24 would make it +24

-1 times 24 is -24

Answer: -24

Step-by-step explanation:

The absolute value of a number is how far away the said number is from zero, so -24's would be 24.

24 x -1 = -24

Answer:

He gained more than 50 yards in the game.

Step-by-step explanation:

Running back in the first quarter in a football game = -8.5 yards

Running back in second quarter = 23 yards

Running back in 3rd quarter = 42.5 yards

Running back in 4th quarter = -2.25 yards

Total gain in the game = -8.5 + 23 + 42.5 - 2.25 = 54.75 yards

That means he gained more than 50 yards in the game.

f(4)= 2(4)-5

f(4)=8-5

f(4)=3

Answer:

[tex]\frac{11}{2}[/tex] or 5.5

Step-by-step explanation:

In order to find the slope of a line using two points on a graph, you must use

[tex]y_2-y_1/x_2-x_1[/tex]

Pluging in the points (-4,7) and (-6, -4) to the formula you will get:

[tex]\frac{-4-7}{-6+4} =\frac{-11}{-2} =5.5[/tex]

The equation for the line would be [tex]\frac{11}{2}[/tex]x+29

Answer:

[tex]y = -\frac{2}{3}x + 6[/tex]

Step-by-step explanation:

y = mx + b is the formula for slope intercept. What we can do is plug in the slope and coordinate points to find the y-intercept.

4 = [tex]-\frac{2}{3}[/tex](3) + b

-2/3 times 3 is -2 so you can fill that in place.

4 = -2 + b

+2   +2    

6 = b

So the y-intercept is 6 now we can complete the equation.

[tex]y = -\frac{2}{3}x + 6[/tex]

Hope that helps and have a great day!

Answer:

= 10x + 20

Step-by-step explanation:

If I helped may I get brainliest?

Answer:

x=6.5

Step-by-step explanation:

1. simplify the equation to 10x + 20 +85

2. minus 20 from both sides to get 10x =65

3. divide 10 from both sides

4. x= 6.5

Answer:

Both are facial expressions bu a frown is with the eyebrows together and forehead wrinkles and usually the person is wooried or sad and a smile is formed primarily by flexing the muscles at the sides of the mouth.

Step-by-step explanation:

Answer:

2 and 7 are alternate interior, along with 5 and 4. They are inside the space created by the parallel lines. 1 and 8 are alternate exterior, along with 6 and 3. They are outside the space created by the parallel lines.

Difference:

Alternate exterior angles are created in the space outside the parallel lines on alternating sides; interior angles are created in the space inside the parallel lines.

I hope this helped, please mark Brainliest, thank you!

Answer:

x=55

Step-by-step explanation:

you have to add the three angles to get 180 first. 180- 21-34=125.

then take the missing angle inside the triangle (125) and subtract by 180.

180-125=55

Answer:

x = 55

Step-by-step explanation:

We know that triangles add up to 180 degrees, so let's start with that. Keep in mind that "y" will be the third degree of the triangle.

21+34+y = 180

55+y = 180

y = 125

Okay, now we know that the third degree is 125. Also, the line that 125 and x are on is a straight line. All straight lines are 180 degrees. Subtract 180 and 125 to get your answer.

180-125 = 55

So your final answer will be x=55, hope this helped!

Answer:

how many times larger? 4 times as large

Step-by-step explanation:

if the radius is half as big as the diameter and the diameter is half of the area

r x r = d

d x d =  a

Answer:

-5,3,11

Plus 8 or subtract 8

Step-by-step explanation:

-13 + 8= -5

-5+8= 3

3+8=11

11+8=19

or

19-8=11

11-8=3

3-8=-5

-5-8= -13

Hope that helps :)
