f+b=160 and f = 2b+12 can be used to find out the number of football cards and number of baseball cards Joey has.
Step-by-step explanation:
Given,
Total cards Joey have = 160
Let,
f be the number of football cards.
b be the number of baseball cards.
According to given statement;
f+b=160 Eqn 1
The number of football cards, f, is 12 more than twice the number of baseball cards.
f = 2b+12 Eqn 2
f+b=160 and f = 2b+12 can be used to find out the number of football cards and number of baseball cards Joey has.

Answer: the missing values are 7, 28 and 14
Step-by-step explanation:
In a proportional relationship, there is a constant relationship between the given variables. Thus, for any change in the value of one variable, there is a corresponding change in the value of the other variable.
The table shows a proportional relationship between values of servings
12 ,4 16 ,8
and values of ounces
21 ? ? ?
Let the missing values be x, y and z
Therefore,
21/12 = x/4
1.75 = x/4
x = 4 × 1.75
x = 7
21/12 = y/16
y = 16 × 1.75 = 28
21/12 = z/8
z = 1.75 × 8 = 14
Answer: 3668.94 m^2
Step-by-step explanation:
35.7 * 15.1 = 539.07
35.7 * 15.1 = 539.07
25.5 * 15.1 = 385.05
25.5 * 15.1 = 385.05
35.7 * 25.5 = 910.35
35.7 * 25.5 = 910.35
539.07 + 539.07 + 385.05 + 385.05 + 910.35 + 910.35 = 3668.94
