Answer:

9 9/16

Step-by-step explanation:

The first step is to find the LCD of 16 and 2

It is 16, and you can multiply the 6 1/2 by 8 which equals 6 8/16

Then you add

3 1/16 + 6 8/16 is equal to 9 9/16, which is your answer.

Hope this helped

Answer:

Train B is traveling faster

Step-by-step explanation:

From the picture, we want to know which train is traveling faster

We can know this by knowing the speed of the trains

Mathematically;

speed = distance/time

Train A

12.5 m in 1 second

speed = 12.5/1 = 12.5 m/s

Train B

100 m in 4 seconds

speed = 100/4 = 25 m/s

So train B is traveling faster

This is because it covered a distance of 100 m in 4 seconds as opposed to train A which covered a distance of 12.5 m

in 1 second

I would say line graph

because many charts and graphs that use time, like years, use line graphs.

One example of this is the stock market, the stock market uses line graph, and I think the best option here is a line graph.

Answer: Line Graph

A line graph would best represent this data because you recording change over time (results from 1972-2008).

Answer:

length is 15 cm

Step-by-step explanation:

4 * 4 * x = 240

16x=240    : divide by 16 on both sides

x = 15

then to check

15 cm x 4 cm x 4 cm = 240 cm^3

Answer:its actually yes, yes, no

I have the answer bc it showed the answer on my test right after

Answer:

y= -2x -5

Step-by-step explanation:

Slope-intercept form:

y= mx +c, where m is the slope and c is the y-intercept.

Parallel lines have the same slope.

Thus, to find the value of the slope of the line, we have to find the slope of the given line.

y= -2x -1

Since the coefficient of x is -2 and the equation is already in slope-intercept form, the slope of the given line is -2.

Substitute m= -2 into the equation:

y= -2x +c

To find the value of c, substitute a pair of coordinates.

When x= -2, y= -1,

-1= -2(-2) +c

-1= 4 +c

c= -1 -4 (-4 on both sides)

c= -5

Thus, the equation of the line is y= -2x -5.

Answer:

[tex] \frac{13}{35} [/tex]

Step-by-step explanation:

To add or subtract two or more fractions from each other, the denominators have to be the same. To make the denominators the same, we should find the least common multiple of 5 and 7. The least common multiple of 5 and 7 is 35. 5 should be multiplied with 7 to get 35 and 7 should be multiplied with 5 to get 35 (with both numerators).

[tex] \frac{4}{5 } - \frac{3}{7} [/tex]

[tex] \frac{4 \times 7}{5 \times 7} - \frac{3 \times 5}{7 \times 5} [/tex]

[tex] \frac{28}{35} - \frac{15}{35} [/tex]

[tex] \frac{13 }{35} [/tex]

When subtracting, only subtract the numerators (the denominators are kept as is).

Answer:

the answer is 13/35

Step-by-step explanation:

Step 1: Add 3x to both sides to get 4 = 3x - 1

Step 2: Add 1 to both sides to get 5 = 3x

Step 3: Divide by 3 on both sides to get 5/3 = x

Answer:

x = [tex]\frac{5}{3}[/tex]  or [tex]1 \frac{2}{3}[/tex]

Step-by-step explanation:

Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

~

Step 1:

Subtract 4 from both sides of the equation:

4 (-4) - 3x = -1 (-4)

-3x = -1 - 4

-3x = - 5

Step 2:

Divide -3 from both sides of the equation:

(-3x)/-3 = (-5)/-3

x = -5/-3

x = 5/3

x = 1 2/3

Answer:

369600 feet per hour

Step-by-step explanation:

1m = 5280ft

5280 x 70 = 369600

Answer:

369,600 feet per hour

Step-by-step explanation:

1 mile = 5,280 feet

70 mph (cheetah's speed) x 5,280 feet (feet in 1 mile) = 369,600 feet (cheetah's speed in feet)

Answer:

Line s and Line t are parallel.

Step-by-step explanation:

Now, we know that angles 1 and 2 are congruent, because they have the same angle measures. Now, looking at their positions, we can see that they are alternate exterior angles.

By the converse of the Alternate Exterior Angle, (I do not remember exactly how the theorem went) if two lines are cut by a transversal and have congruent alternate exterior angles, then the lines are parallel. Using this theorem, we can find that lines s and t are parallel, because they are cut by a transversal and their alternate exterior angles are congruent.

I hope you find my answer and explanation to be helpful. Happy studying.

Answer:

[tex]3\sqrt7[/tex]

Step-by-step explanation:

This is because you can split 63 into two numbers, [tex]\sqrt{9}[/tex] and [tex]\sqrt{7}[/tex]. When you simplify [tex]\sqrt{9}[/tex] turns into 3 but [tex]\sqrt{7}[/tex] will not simplify further so it will be [tex]3\sqrt{7}[/tex].

Answer:

slope of perpendicular line is -1/4

Step-by-step explanation:

slope of standard equation of line that is ax+ by = c is

slope m = -a/b

given equation is

12x – 3y = 81

comparing it with ax+ by = c

a = 12

b = -3

thus

slope of given line = -12/-3 = 4

we also know product of slope of two perpendicular line is -1

let the slope of other line be m

thus,

product of given line line and perpendicular line is -1

4*m = -1

m = -1/4

Thus,

slope of perpendicular line is -1/4

Answer:

Answer:

A. 1.88

Step-by-step explanation:

In less fancy terms, a constant of proportionality is essentially a rate of change - or more specifically, a unit rate.

It's the number we multiply our independent variable by to get the y. You can find this by simply dividing the y value by the x value!

Let's choose the first order pair (2, 3.76).

[tex]3.76 \div 2 = 1.88[/tex]

We can check that this table IS constant by doing the same with the other values... we should always get 1.88!

[tex]7.52 \div 4 = 1.88\\9.40 \div 5 = 1.88\\15.04 \div 8 = 1.88[/tex]

This is true for all values - which means our constant is 1.88

The y axis goes up and down. The slanted line meets the Y axis at 1.

Answer:

1

Step-by-step explanation:

the y intercept would be 1 because that’s where the line passes through the y axis. A more mathematical term would be, the y intercept is (0,1)
