3 questions 1.there was 119 percent change in the number of public order offences between April 2018 to March 2019 compared with the number of public order offences between April 2008 to March 2009 (to the nearest number)
A-204,519
B-223,948
C-376-383
D-447-896

2.if the total recorded crime (including some types of crime not show in the table) between 2018 to match 2019 is 5,950,499 then what percentage of the total recorded crime is made up of robbery offences
A-2.72%
B-1.44%
C-33.88%
D-28.08%

3.which of the different categories of crime listed saw the greatest percentage fall in offences in April 2018 to March 2019 compared with April 2008 to March 2009
A-other crimes against society
B-sexual offences
C-violence against the person
D-theft offences

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
