20x20
Answer: 73
Step-by-step explanation:
8² = 64 3² = 9 64 +9 = 73
8 to the power of 2 means 8 × 8 that is 64
3 to the power of 2 means 3 × 3 that is 9
Answer:
The cost of each pound of walnuts is $1.25 and each pound of chocolate chips is $2.50
Step-by-step explanation:
Let,
x be the price per pound of walnuts
y be the price per pound of chocolate chips
According to given statement,
4x+8y=25 Eqn 1
2x+3y=10 Eqn 2
Multiplying Eqn 2 by 2
2(2x+3y=10)
4x+6y=20 Eqn 3
Subtracting Eqn 3 from Eqn 1
(4x+8y)-(4x+6y)=25-20
4x+8y-4x-6y=5
2y=5
Dividing both sides by 2
Putting y=2.50 in Eqn 2
2x+3(2.50)=10
2x+7.50=10
2x=10-7.50
2x=2.50
Dividing both sides by 2
Hence,
The cost of each pound of walnuts is $1.25 and each pound of chocolate chips is $2.50
Simplify both sides of the equation
-5/2 x +3/4 x = -3/4
Combine like terms
(-5/2 x + 3/4 x )
-7/4 x = -3/4
-7/4 x = -3/4
Multiply both sides by 4/(-7)
(4/-7)*(-7/4 x ) = (4/-7 ) * ( -3/4 )
x = 3/7
