If you are in elementary school, it is easier to just divide by 2.
90/2 = 45. Therefore, half of 90 is 45.
First number (A): x + 23
Second number (B): 2A - 18
Product = (x + 23)(2A - 18)
= 2Ax - 18x + 46A - 414
Answer:
Step-by-step explanation:
2a-5a = -3a, combine like terms
-3a = -3a , this is true all the time so ...
The equation 2a-5a = -3a has infinite many solution.
Step-by-step explanation:
b is the correct answer.
Sophie will have a greater daises to total flowers ratio than Eleanor. To make this easier to see, let's assume the boquets have 10 flowers each, and Eleanor uses 2 daisies and 8 tulips, while Sophie uses 5 daisies and 5 tulips. Then Eleanors ratio is 2:10=1:5, while Sophie's ratio is 5:10=1:2.
