11x-8+7(x-1)

expanded form.

7(x-1)=7x-7

11x-8+7x-7

Hey there!

Answer = 18x + -15

Explanation:

Let's simplify step-by-step.

11x - 8 + 7(x-1)

Distribute:

= 11x + -8 + (7)(x) + (7)(-1)

= 11x + -8 + 7x + -7

Combine like terms:

= 11x + -8 + 7x + -7

= (11x + 7x) + (-8 + -7)

= 18x + -15

So therefore, that is how you found your answer: 18x + -15

A rectangular table top has dimensions as 1.52m and 0.75m. Find the perimeter in cm
Elis [28]

That is a question about perimeter of rectangle.

The perimeter of a geometric shape is the sum of the value of the all sides.

In a rectangle, the opposite sides are cogruentes (equals). For example, look at picture below. In that rectangle, the sides AB and DC are equals, and the sides AD and BC are equals.

So, the sides of that rectangular table are: 1.52m, 1.52m, 0.75m and 0.75.

Therefore, the perimeter of that rectangle is 1.52+1.52+0.75+0.75= 4.54m.

But that is not the final answer because that is the perimeter in meters and the question want the answer in centimeters.

1 meter has 100 centimeter, so we need to multiplicate the perimeter by 100.

Thus, the perimeter of that rectangular table is 4.54\cdot 100 = 454cm.

Aidan bought a pizza cut into 5 slices. If he ate one slice for lunch, what percentage of the pizza remained uneaten?
Over [174]

Answer:

80%

Step-by-step explanation:

You started of with 5/5 once one slice was eat it became 4/5

you must then convert 4/5 into a percent

To convert a fraction to a percent, divide the numerator by the denominator. Then multiply the decimal by 100.

so 4 divided by 5 =0.8

0.8 x 100= 80

80%
