Answer:
Only when any equation you find among those numbers can be simplified into one of the four main equations, which means you only have four different true statements and lots of equivalences. 20 = 40 - 20. As the two addends are the same, so there would be only four different equations for a set of math mountain numbe

Answer:
1240
Step-by-step explanation:
Number of boys to a girl is
x:y= 11:9
9x= 11y
There are 124 more boys in the schooll than girls
x= 124+y
Substitute 124+y for x
9(124+y)= 11y
1116+9y= 11y
1116= 11y-9y
1116= 2y
y= 1116/2
y= 558
Number of girls is 558
The number of boys can be calculated as follows
= 558+124
= 682
Hence the total number of students is
= 682+558
= 1240
Answer:
D
Step-by-step explanation:
To shift <em>h</em> units to the right, replace <em>x</em> with <em>x</em> - <em>h</em>
To shift <em>h</em> units to the left, replace <em>x</em> with <em>x</em> + <em>h</em>.
To shift <em>k</em> units up, add <em>k </em>to the end of the formula for the function.
To shift <em>k</em> units down, subtract <em>k</em> from the end of the formula.
Example:
is shifted <u>left</u> 2 units and <u>up</u> 6 units.
Caution: the right/left shifts sometimes look backwards!
