Answer:
a is 100 b is 5
Step-by-step explanation:
a is 100 because if you substitute 100 for a and 1 for x (decrease of 5 dollars) you get 600 yearbooks sold which is a curate according to the economics class prediction
b is 5 because substituting 5 into b and 1 to x gives you 45 dollars per year book. this is accurate because a 5.dollar decrease in price makes the year books 45 dollars instead of 50
75lbs of food = 15% tiger's food weight
?lbs tiger= 100% tiger's body weight
So you want to take the amount of food (75lbs), divide it by the amount of the tiger's food weight (15%) and then multiply it by it's total body weight (100%)
So 75 / 15 = 5
and 5 x 100 = 500
so the tiger = 500lbs
All of them are correct . Number six is 0.28 as a decimal
7 x 4
-- = 28; 0.28 is the answer
25 x 4
Y(smiths score)= x (Jones elementary score) - 30 (scored 30 less points than Jones)
Y=x-30
Answer:
8
Step-by-step explanation:
5 = 40
1 = x
Then we multiply by the rule of crisscrossing
5 x X = 40 x 1
5x = 40 then divide both by 5
X = 8
