Answer:

B) addition property

Step-by-step explanation:

thinking that 3x - 30 - 0 should equal 0.

3x - 30 - 0 = 0

to get rid of numbers on side with variables, we have to add them to both sides (to make it 0 in side with variable.)

3x - 30 - 0 = 0

+30 +0 = +30 +0

3x = 30 <- step 4

Answer:

Step-by-step explanation:

To find the median, arrange the data in ascending order

10,20,30,40,50,60,70,80,90

Number of data = 9 . It is a odd number

So, median will be the (n+1)/2 th term

$\left(\dfrac{9+1}{2} \right)^{th \ term} = (\dfrac{10}{2})^{th \ term} = 5^{th \ term}$

Median = 50

Dvinal [7]

Answer:

t=7,t=0

Step-by-step explanation:

2t^2-14t+3=3

Subtract 3 from both sides

2t^2 - 14t +3 - 3 = 3-3

Simpilfy

The distance between Rosa's house and her school is 4 1/2 of a mile. She ran 3 mile. What fraction of the distance between her h

Licemer1 [7]

Answer:

Rosa ran $\frac{2}{3}$ of the total distance between her house and her school.

Step-by-step explanation:

Distance between Rosa's house and her school = $4\frac{1}{2}$ miles ≈ 4.5 miles

She ran distance = 3 miles

Therefore, fraction of the total distance between her house and school she run = $\frac{\text{Distance run by Rosa}}{\text{Total distance between her house and school}}$

= $\frac{3}{4.5}$

= $\frac{30}{45}$

= $\frac{2}{3}$

Therefore, Rosa ran $\frac{2}{3}$ of the total distance between her house and her school.

The GCF is $mn^{4} p^{3}$

Explanation:

The GCF or greatest common factor is the factorization of two or more numbers to determine the greatest number that they have common.

The given terms are $m^{7} n^{4} p^{3}$ and $m n^{12} p^{5}$

To determine the gcf of these two terms, let us find the greatest number that they have in common.

Comparing the powers of m from both the terms, we have,

$g c f\left(m^{7}, m\right)=m$

Similarly, comparing the powers of n from both the terms, we have,

$g c f\left(n^{4}, n^{12}\right)=n^{4}$

Also, comparing the powers of p from both the terms, we have,

$g c f\left(p^{3}, p^{5}\right)=p^{3}$

Thus, the GCF of the terms $m^{7} n^{4} p^{3}$ and $m n^{12} p^{5}$ is $mn^{4} p^{3}$
