Answer:
Therefore the cost of each apple is $ 0.50 and each banana is $1.
Step-by-step explanation:
Given , Amanda buys 6 apples and 5 bananas , it will cost $8.00 and if she buys 5 apples and 7 bananas it will cost $9.50.
Let the cost of one apple be =$ x
and the cost of one banana be =$y
According to the problem,
6x+5y=8.........(1) 5x+7y= 9.50............(2)
Equation (1)×5 - equation (2) × 6
30x +25 y-(30x+42y)= 40-57
⇔30x+25y -30x-42y= -17
⇔-17y =-17
⇔y=1
putting the value of y in equation (1)
6x+5×1=8
⇔6x = 8-5
⇔6x=3
⇔
⇔x = 0.50
Therefore the cost of each apple is $ 0.50 and each banana is $1.
Answer:
Step-by-step explanation:
if 36^12-m=6^2m , find the value of m
To make the exponents equal , we need to get the same base.
The base of both sides of equation are not same.
36 can be written as 6^2
now base of both sides are same . so we equate the exponents
add 2m on both sides
divide by 4 on both sides
The value of m is 6
Answer:
Option A: 3x + 5x - 4 = 1
Step-by-step explanation:
Given that:
3x + y = 1 ------------- eq1
y + 4 = 5x ------------ eq2
Now for substitution in eq1 we will get a value of y from eq2:
y = 5x - 4
Substituting in eq1 we get:
3x + 5x - 4 = 1
i hope it will help you!
34 multiplied by 3 is 102, subtract 2 and your answer is 100.
