4 + 3(2-1) =7

And continue the pattern

A section of a rectangle is shaded. The area of the shaded section is 63 square units. What is the value of x?
ella [17]

Answer:

x=11  

Step-by-step explanation:

We have been given a graph of a rectangle. The area of the shaded section is 63 square units. We are asked to find the value of x.

We can see from our given graph that shaded section forms a trapezoid, so we will use area of trapezoid formula to find the value of x.

\text{Area of trapezoid}=\frac{(a+b)}{2}\times h, where, a and b represents the parallel sides of trapezoid and h represents height of trapezoid.

Upon substituting our given values in above formula we will get,

63=\frac{7+x}{2}\times 7

63=(7+x)*3.5

Upon dividing both sides of our equation by 3.5 we will get,

\frac{63}{3.5}=\frac{(7+x)*3.5}{3.5}

18=7+x

Let us subtract 7 from both sides of our equation.

18-7=7-7+x

11=x

Therefore, the value of x is 11 units.

8 out of 300 were defective.

\frac{8}{300}=\frac{x}{3000} \\  \\ 8*3000=300*x \\  \\ 24000=300x \\  \\ 80=x

80 pairs were defective

Which of these is equivalent to the following expression? 5s - 11b + 3s - 12b A. -b + 8s -B.23b + 2sC. -23b + 8s D. b + 8s
Marina86 [1]

Answer:

Option b) and c) are correct

Step-by-step explanation:

Given expression is  5s - 11b + 3s - 12b

5s - 11b + 3s - 12b=8s-23b (Rearranging the right hand side terms)

5s - 11b + 3s - 12b =-23b+8s

Option c) is correct

By the definition of equivalent the given expression is the sum of the two terms ( the terms may vary or equal)

From the definition of equivalent we get, Option b) is also correct

Therefore  Option b) and c) are correct
