Answer:
122.4
Step-by-step explanation:
Remember PEMDAS
Parentheses
Exponents
Multiply
Divide
Add
Subtract
(52-15+2)=39
39x3=117
117+5.4=122.4
41+0.10x = 31+0.15x
10 +0.10x=0.15x
10=0.05x
x=10/.05
x= 200 text messages
check 200*0.10 = 20 +41 =61
200*0.15 = 30+31 = 61
they equal each other so number of texts is 200
-2.5 and 4
You can get this by factoring to the equation (2x + 5)(x - 4)
Answer:
Same here.
Step-by-step explanation:
I'm usually bored, that's why I mainly use this site.
:D
Number 1.) In game 1 he scored 180 points, In game 2 he scored 200 points this means the score went up , so now you have to add, ( Addition ).
180 + x = 200 | x=? , well 180 + 20 = 200.
Since there is 20 points added to 180 which gives us 200 there is an 11.11% increase .
__________________________________________________
Number 2.) , In the next game he scored 200 points , it asks what is the decreased number?
how many numbers did his score drop? 200 - 180 = 20 |
Now we must work backwards , There is a loss in points , ( 20 ) , so there is an 10% decrease.
(200-180) / 180 * 100% = 10%
20 / 200 * 100% = 10%
20 = The Answer with an 11.11% increase , there is a 10% decrease.
I hope this helps you a lot
