Answer:
85 cents
Step-by-step explanation:
Let a represent the price of pineapples
Let p represent the price of peaches
74p + 9a= 14p + 21a
p = 17 cents
Substitute 17 for p
74(17) + 9a = 14(17) + 21a
1258+9a= 238+21a
1258-238= 21a-9a
1020= 12a
a= 1020/12
a= 85
Hence the price of pineapples is 85 cents
The sum of a and b will be the coefficient of the x term of the trinomial. This can be seen below.
(x + a)(x + b)
= x² + bx + ax + ab
= x² + (a+b)x + ab
x is being multiplied by both a and b individually and the products are being added, so sum of a and b appears as the coefficient of x term.
Thus the answer to this question is option C
The answer to your question is 35,568
Answer:
3 or 6/2
Step-by-step explanation:
4--2 (you add there is a subtraction of a negative) over or divided by 3-1
First, we’re going to use this formula:
2nd number - 1st number
————————————— x 100%
1st number
If we plug in the numbers to this equation:
23-20
———- x 100%
20
And subtract 23 to 20, the answer to this equation is:
3
—- x 100% = 15%
20
In this case, the percent of increase is 15%.
