Answer:
b=15 g=25
Step-by-step explanation:
lets translate that story problem to mathematics equations
the problem told that no. of girls are 10 more than no of boys so this will =
g=b+10
then in class there are 40 students that means
g+b=40
now we have to equations with two variables then we should substitute
(b+10)+b=40
lets remove the brackets
2b+10=40 subtract 10 from both sides
2b=30 now divide both by 2
b=15 so g=25 after you write the equation once again with the new proof or number
Probablity=desiredoutcomes/totalpossible
total possible=number of cards or number of letters which is 8 letters
desired is number is the letter "I", which is 3
3/8 is probality
in favor it is 3:5, because we are looking at odds of picking vs not picking
not is 5/8
3:5 s answer
A is answer

Step-by-step explanation:
<span>The lowest common multiple is the smallest number that is a shared multiple of a set of numbers. 9 x 1 = 9, 9 x 5 = 45 and 9 x 9 = 81. The smallest common multiple is 9.</span>
Answer:
-22 1/2
Step-by-step explanation:
-2 1/2 *s
Let s = 9
-2 1/2 (9)
Change to an improper fraction
-5/2 *9
-45/2
Change back to a mixed number
-22 1/2
