Well if we multiply 3.48 times two which would make 4 toothbrushes it would be 6.96. So this means if we wanted a better deal on more toothbrushes. The answer would be the package of 4

3.48x2= 6.96. Therefore if you bought the pack of 4 toothbrushes it would be a better deal bc you can get the same amount of toothbrushes for less since the 4 pack is 6.60 =)

A machine packs at a constant rate of 2/3 of a box every 1/2 minuet. What’s is the number of boxes per minute that’s the machine
lions [1.4K]
For this case what we can do is the following rule of three:
 2/3 of a box ------> 1/2 minutes
 x of a box ---------> 1 minute
 Clearing x we have:
 x = (1 / (1/2)) * (2/3)
 Rewriting:
 x = 2 * (2/3)
 x = 4/3
 Answer:
 the number of boxes per minute that the machine packs is:
 x = 4/3

balu736 [363]

Answer:

A. x = 2 and y =2

B. x = 3 and y = -1

Step-by-step explanation:

A. { x = 3y − 4

    2x − y = 2

1) Substitute the value of x

2(3y − 4) − y = 2

2) Solve the equation for y

y = 2

3) Substitute the value of y

x= 3(2) -4

4) Solve the equation for x

x = 2

Final Solution: x = 2 and y =2

B. { 3x + 2y = 7

     −x + y = −4

1) Multiply both sides of the equation by 3

-3x + 3y = -12

2) Eliminate one variable by adding the equations

  3x + 2y = 7

<u>+ (−3x + 3y = −12)</u>

   5y = -5

3) Divide both sides of the equation by 5

y = -1

4) Substitute the given value of y into the equation -x + y = -4

-x + (-1) = -4

5) Solve the equation for x

x = 3

Final Solution: x = 3 and y = -1

In this triangle, what is the value of x?
nalin [4]

Answer: x=56.5\ km

Step-by-step explanation:

Given the right triangle in the image, you need to remember the following identity:

cos\alpha=\frac{adjacent}{hypotenuse}

Observe the triangle. You can identify that:

\alpha=28\°\\adjacent=x\\hypotenuse=64

Then, knowing these values, you can substitute them into  cos\alpha=\frac{adjacent}{hypotenuse}:

cos(28\°)=\frac{x}{64}

Finally, you have to solve for "x".

Therefore, the value of "x" rounded to the nearest tenth is:

64*cos(28\°)=x\\x=56.5\ km
