Step-by-step explanation:
Answer:
A) Number of mango trees
B) Percentage of coconut trees = 60%
Total number of trees = 2230 trees
C)number of mango trees = 40% × 2230
D) 892 mango trees
Step-by-step explanation:
A) What is asked is the number of mango trees
B) We are given;
Percentage of coconut trees = 60%
Total number of trees = 2230 trees
C) Number sentence is defined as when we use an equation or inequality to describe an expression using numbers and signs.
We have percentage of coconut trees = 60%.
Thus, percentage of mango trees = 100% - 60% = 40%
In this case, the number sentence is; number of mango trees = 40% × 2230
D) number of mango trees = 40% × 2230 = 892
(8)2-(3x)2 is the correct formula
Answer: The cost of each pound of jellybean is $2.5
The cost for each pound of trail mix is $1.5
Step-by-step explanation:
Let the cost for each pound of jellybeans be x.
Let the cost of each pound of trail mix be y.
Based on the information given, we can form an equation which will be:
For 2 pounds of jellybeans and 12 pounds of trail mix, the total cost is $23. This will be:
2x + 12y = 23 ...... i
For 5 pounds of jellybeans and 3 pounds of trail mix, the total cost is $17. This will be:
5x + 3y = 17...... ii
2x + 12y = 23 ...... i
5x + 3y = 17...... ii
Multiply equation i by 5
Multiply equation ii by 2
10x + 60y = 115 ...... iii
10x + 6y = 34 ..... iv
Subtract iv from iii
54y = 81
y = 81/54
y = 1.5
The cost for each pound of trail mix is $1.5
From equation i
2x + 12y = 23
2x + 12(1.5) = 23
2x + 18 = 23
2x = 23 - 18
2x = 5
x = 5/2 = 2.5
The cost of each pound of jellybean is $2.5
