Answer:
B. 21:18
Step-by-step explanation:
7/6 x 3 = 21/18
This means they are equivalent.
Answer:
Option B is correct.
Step-by-step explanation:
Let's first turn 7:6 into a fraction:
=> 7:6 = 7/6
Now, let's simplify all the options to see which one is the correct answer.
Option A:
=> 14:18=> 14/18=> 7/9=> 7/9 ≠ 7/6Therefore, Option A is incorrect.
Option B:
=> 21:18=> 21/18=> 7/6=> 7/6 = 7/6Therefore, Option B is correct.
Option C:
=> 21:12=> 21/12=> 7/4=> 7/4 ≠ 7/6Therefore, Option C is incorrect.
Option D:
=> 18:14=> 18/14=> 9/7=> 9/7 ≠ 7/6Therefore, Option D is incorrect.
We can conclude that Option B is correct.

What’s the slope intercept form?
At first I thought it was y=-4/3x+7 but it’s not. Pls help!
Answers
Answer:
y = - [tex]\frac{5}{4}[/tex] x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 7) and (x₂, y₂ ) = (4, 2) ← 2 points on the line
m = [tex]\frac{2-7}{4-0}[/tex] = [tex]\frac{-5}{4}[/tex] = - [tex]\frac{5}{4}[/tex]
The line crosses the y- axis at (0, 7 ) ⇒ c = 7
y = - [tex]\frac{5}{4}[/tex] x + 7 ← equation of line
Kay is running a 13.5 km race. If she runs at a rate of 8 2/5 km/he for 1.5 hours, how many kilometers will she have left to run to finish the race?
Answers
The number of kilometers she will have left to run to finish the race is 0.9 km.
Given the following data:
Total distance = 13.5 kmSpeed = [tex]8\frac{2}{5} \;km/hr[/tex]Time = 1.5 hoursTo determine the number of kilometers she will have left to run to finish the race:
First of all, we would calculate the distance she has covered by using this formula;
[tex]Distance = speed \times time\\\\Distance = 8\frac{2}{5} \times 1.5\\\\Distance = \frac{42}{5} \times \frac{3}{2} \\\\Distance = \frac{63}{5}[/tex]
Distance = 12.6 meters.
For the distance left:
[tex]Distance\;left = Total\;distance - Distance\;covered\\\\Distance\;left =13.5 -12.6[/tex]
Distance left = 0.9 km.

Answer:
1) -2x - 3
2) -2a - 2
Step-by-step explanation:
Problem 1
To solve this problem, we only have to combine like terms. What are the like terms in this problem? Well, we have two x-terms (-10x and 8x) and two integers, or constants (1 and -4). So, let's rearrange the expression and then combine those terms.
-10x + 8x + 1 - 4
-2x - 3
Problem 2
This expression is a little more complicated since we have to distribute a 2 onto the two terms in the parentheses.
2(1 - a) - 4
2(1) - 2(a) - 4
2 - 2a - 4
Next, we can combine like terms.
-2a + 2 - 4
-2a - 2

Sean is drinking a slushy as fast as he can. The amount of slushy left in the cup (in milliliters) as a function of time (in seconds) is graphed. How long did it take Sean to finish the slushy?
______ seconds
Answers
Answer:
75 seconds
Step-by-step explanation:
The graph intersects the x axis at 75 seconds. That means y = 0, and y is the amount remaining (in ml).
After 75 seconds the amount of slushy left in the cup becomes zero the answer is 75 seconds.
What is a line graph?A line graph is a type of graph where the data points are connected by segments of straight lines.
We have a line graph shown in the picture.
Sean is drinking a slushy as fast as he can. The amount of slushy left in the cup (in milliliters) as a function of time (in seconds) is graphed.
As we can see the amount of slushy left in the cup is decreasing as the time increases.
At time = 75 seconds
The amount of slushy left in the cup = 0
Thus, after 75 seconds the amount of slushy left in the cup becomes zero the answer is 75 seconds.

t = S / v time = distance / speed
For Tom t = 12 m / 4 mph = 3 hours to cover course
Tom will finish at 8:13 + 3 = 11:15
th = 12 m / 8mph = 1.5 hours to cover course

A transgenic organism is an organism which has been modified with genetic material from another species. The biggest use of transgenic organisms is for agriculture growth, the development of genetically modified crops.
They also research with transgenic mice. Mice can be modified with human DNA for the purpose of testing medical treatments and seeing how they might behave in a human.
Researchers are concerned though that interbreeding between transgenic and wild organisms could have unforeseen consequences and could reign havoc on our ecosystem.
