Answer:

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3 − 2x = 15

−2x + 3 = 15

Step 2: Subtract 3 from both sides.

−2x + 3 − 3 = 15 − 3

−2x = 12

Step 3: Divide both sides by -2.

−2x/-2 = 12/-2

Hope this helps!

Which of the following best describes the equation below?

Reika [66]

4(x + 9) + 5x = 9x - 36

=> 4x + 36 + 5x = 9x - 36

=> 9x + 36 = 9x - 36

=> 9x - 9x = -36 - 36

=> 0 = -72

You can see that the equation doesn't hold true.

So there is no solution for this equation.

Answer is C. no real solutions

viktelen [127]

Assuming there is no specific percentages in the grade book, you would need a grade of 95 to get your whole grade to 90. You find this out by working backwards starting with 90 to find average. You take 90 times 2 which equals 180 and you subtract 85 from that to get 95! Brainliest?

ANSWER

Given,

Diameter of the base of the cylindrical container d=56 cm

Hence, radius of the base of the cylindrical container r=

=28 cm

Dimensions of rectangular solid is (32 cm×22 cm×14 cm)

We know that when a body is completely submerged in a container containing water,

the rise in the volume of water in the container is equal to the volume of the body.

Let, the water rises to a height h.

Hence,

Volume of water rises in cylindrical container =Volume of the rectangular solid

πr

h=32×22×14 cm

×(28)

×h=9856 cm

22×784

9856×7

h=4 cm
