Use inverse operations to solve equation 15=x/6-1​

Answer:

x=90.

Step by step explanation:

To solve the expression 15=\frac{x}{6}-1, and obtaining a value for x we can do the following:

  1. Add 1 both sides of the equation. This will result in 15+1=\frac{x}{6}-1+1⇒16=\frac{x}{6}.
  2. Multiply both sides by 6, which yields 15\times6=\frac{x}{6}\times6. This results in 90=x.

Value of x is 2.

Step-by-step explanation:

  • Step 1: Given that x+1/3 = x/2

Cross-multiply to find the value of x.

⇒ 2(x + 1) = 3x

⇒ 2x + 2 = 3x

⇒ x = 2

Find the volume and explain please ASAP.
olya-2409 [2.1K]

Answer:

1395in^3

Step-by-step explanation:

First find the volume of the cuboid, 15in x 9in x 7in = 945in^3

Then find the volume of the rectangular pyramid using the formula V=lwh/3, the total height is 17in so subtract the height of the cuboid from the total height, giving you 10in.

V=(15in)(9in)(10in)/3 = 450in^3

450in^3 + 945in^3 = 1395in^3

Answer: C) y ≥ 3x - 2;  y\leq \dfrac{1}{2}x+3

<u>Step-by-step explanation:</u>

Blue line:

y-intercept (b) = -2

slope (m) is 3 up, 1 right = 3

shading is above

⇒ y ≥ 3x - 2

Yellow line:

y-intercept (b) = 3

slope (m) is 1 up, 2 right = \dfrac{1}{2}

shading is below

\implies \bold{y\leq \dfrac{1}{2}x+3}

Eric earned 60 points on his last test. If there were 75 possible points, what was his percent grade?
klemol [59]
This is a proportion problem. Eric earned 60 out of a possible 75 points, so the ratio is 60/75. You put that equal to x, so 60=x% and 75=100%. So it would look like
<u>60</u> = <u>  x  </u><u>
</u>75<u />    100
then you cross multiply 60 and 100, and 75 and x, so you get
6000=75x
then divide by 75 and you have your percent :)
