Answer:
Margaret has 2 flowers
Step-by-step explanation:
First we can make a set of equations
j = 3m
a = 3j
a + j + m = 26
Since j = 3m we can rewrite Anna's equation as a = (3(3m)) or simply a = 9m
Now we can plug in the equations for Anna and Jessica into the main equation
9m + 3m + m = 26
13m = 26
m = 2
r · 7 ≤ 21 [r multiplied by 7 is less than or equal to 21]
7r ≤ 21
[If you wanted to solve it]
7r ≤ 21 Divide 7 on both sides to get "r" by itself
r ≤ 3
