Which expression is equivalent to 3m+1-m?

Lisa [10]

Answer:

option (a) is correct.

2 + m - 1 + m is an equivalent expression to the given expression 3m+1-m

Step-by-step explanation:

Given expression 3m+1-m

We have to choose an equivalent expression from given options.

Equivalent expression are those expression that looks different but are same.

Like 4+2 = 6 and 3+ 3 = 6

Both have same value but looks differently.

Like terms are term having same variable with same degree.

Consider the given expression 3m+1-m

Simplify by adding like terms,

3m + 1 - m = (3-1) m + 1

Thus, (3-1) m + 1 = 2m + 1

Also 2m + 1 can be written as m + m + 2 - 1

Thus, option (a) is correct.

Given the diagram below, what is the length of segment EF

bekas [8.4K]

Let x = length of segment EF.

Assume that
(a) line segments AD, EF, and BC are parallel, and
(b) the vertical distance between AD and EF is equal to the vertical distance between EF and BC.

Then from similarity between geometric shapes, we can write
$\frac{2.2}{x} = \frac{x}{4.8}$
$x^{2} =(2.2)(4.8)=10.56$
x=3.2 (nearest tenth)

Answer: B. 3.2

Arrange these numbers in increasing order: 216,000,000, 2.2 × 10 to the 3rd power, 3.1 × 10 to the 7th power, 310,000

ziro4ka [17]

216,000,000
2.2 × 10 to the 3rd power = 2.2 * 10^3 = 2,200
3.1 × 10 to the 7th power = 3.1 * 10^7 = 31,000,000
310,000

Increasing order:
2,200 , 310,000 , 216,000,000 , 31,000,000

So increasing order with original numbers:
2.2 × 10 to the 3rd power, 310,000, 216,000,000, 3.1 × 10 to the 7th power
