1 meter = 3.28 ft
A = L * l = 2 * 3 = 6 square meter
To tranform it into square feet: 6 * 3.28 = 19.68 sq ft
1) Sundaes - $2 ; Banana Splits - $3
3x + 2(x+8) = 156
3x + 2x + 16 = 156
5x = 156 - 16
5x = 140
x = 28 banana split ; x + 8 = 28 + 8 = 36 sundaes
2) Palanzio's = 6.80 + 0.90x ; Guido's = 7.30 + 0.65x
6.80 + 0.90x = 7.30 + 0.65x
0.90x - 0.65x = 7.30 - 6.80
0.25x = 0.50
x = 2 number of toppings.
6.80 + 0.90x = 7.30 + 0.65x
6.80 + 0.90(2) = 7.30 + 0.65(2)
6.80 + 1.80 = 7.30 + 1.30
8.60 = 8.60
3) 6x - y = 4 ; y = 4x + 2
6x - (4x+2) = 4
6x - 4x - 2 = 4
2x = 4 + 2
2x = 6
x = 6/2
x = 3
y = 4x + 2
y = 4(3) + 2
y = 12 + 2
y = 14
6x - y = 4
6(3) - 14 = 4
18 - 14 = 4
4 = 4
Answer:
The solution is x = 1/log(6)
Step-by-step explanation:
Hi there!
First, let´s write the equation:
6ˣ + 2 = 12
subtract 2 at both sides of the equation
6ˣ = 10
apply log at both sides of the equation
log(6ˣ) = log(10) log(10) = 1
Apply logarithm property: log(xᵃ) = a log(x)
x log(6) = 1
Divide both sides by log(6)
x = 1/log(6)
The solution is x = 1/log(6)
Have a nice day!
