Answer:

Let x cm be the width of the photograph.

Length of photograph

= (2x-1)cm

Area of photograph

= (2x-1)(x)

= x(2x-1)

= (2x²-x)cm²

(2x²-x)cm²=91cm²

       2x²-x=91

           

x₁=-6.5, x₂=7

Answer:

Length = 13

Width = 7

Step-by-step explanation:

Given:

length = 2(width) - 1

Area of a Rectangle = lω = 91 cm²

Calculation:

Area of a Rectangle = lω = 91 cm²

(2ω-1)ω = 91

= 2ω²- ω - 91 = 0

=(2ω+13)(ω-7)=0

ω = -6.5       ω=7

length = 2(width) - 1

l=2(7) - 1

l = 13

Johnny spend 1/7 of his income on Food, 1/10 of his income on gas, and 3/8 of his income on rent. What percentage of his income
Agata [3.3K]

Answer:

  38.2%

Step-by-step explanation:

1/7 ≈ 14.29%

1/10 = 10.00%

3/8 = 37.50%

The total that Johnny has allocated for food, gas, and rent is ...

  14.29% + 10.00% + 37.50% = 61.79%

So, the remaining amount is ...

  100% -61.79% = 38.21%

About 38.2% of Johnny's income remains.
