On a recent test, rudi correctly answered 30 out of 40 questions. what percent of her questions did rudi answer correctly?

Step-by-step explanation:

First we put this into a fraction

30

40

The bottom number must reach 100

This means we must divide 100 by 40

This gives us 2.5

Therefore we multiply 30 by 2.5 to give us

75

So therefore she got 75% of all questions right

step-by-step explanation: examine the two-step equation.

−  

7

4

+  

x

4

= 2

which property of operations allows you to add the same constant term to both sides?

multiplication property of equality

division property of equality

addition property of equality

subtraction property of equality

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
