Answer:
x = lillies
y = tulips
x + y = 13
1.25x + .90y = 14.85
-1.25x - 1.25y = -16.25
1.25x + .90y = 14.85
-0.35y = -1.40
y = 4 tulips
x + 4 = 13
x = 9 lillies
(9 lillies, 4 tulips)
Step-by-step explanation:
the blank is 162
since 81 and 81 are both perfect squares the middle term (blank) will be the product of their roots times 2
√81=9
√81 =9
9 x 9 x 2
= 162
Answer:
80
Step-by-step explanation:
For these types of counting problems, just multiply all of the levels.
For example, this would be
4 choices
5 choices
4 choices
Multiply 4*5*4, and you get 80.
We can start off by making 12 1/2 to an improper fraction:
12 1/2 = 25/2
Divide the large jar of salsa by the small jar of salsa: 75 / 25/2.
Reciprocal of second and turn divide to multiply:
75 * 2/25.
150/25 = 6.
So 6 jars of small salsa = 1 large jar of salsa.
