If 1/4x - 1/4 = 2 then 2 + 1/4 = 1/4x.
so 3/4 = 1/4x
3/4 is equal to 1/1.33 (reduce by dividing both numerator and denominator by 3)
so 4 x ? = 1.33. 1.33 / 4 = 0.3325
so (if you're solving for x) I believe the answer is x = 0.3325

A triangle has a side length of 19inches and a perimeter of 95inches. A similar triangle has a corresponding side length of 20in
Rom4ik [11]

Answer:

100 inches

Step-by-step explanation:

A triangle has a side length of 19inches and a perimeter of 95inches. A similar triangle has a corresponding side length of 20inches. Find the perimeter of the larger triangle.

This is calculated using proportion

Side length/Perimeter

Hence:

Side length of smaller triangle = 19 inches

Perimeter of smaller triangle = 95 inchee

Side length of larger triangle = 20 inches

Perimeter of larger triangle = x

19/95 = 20/x

Cross Multiply

19x = 95 × 20

x = 95 × 20/19

x = 100 inches

The perimeter of the larger triangle = 100 inches

A patio has an area of 1420 square feet. If the length is 45 1/2, what is the width​
Anni [7]

[ Answer ]

\boxed{Width \ = \ 31\frac{19}{91} \ Ft^{2}}

[ Explanation ]

Area = 1420

Width = 45\frac{1}{2}

Area For Rectangle: Length · Width

Use division to find width:

1420 ÷ 45\frac{1}{2}

Convert mixed numbers to fractions:

1420 = \frac{1420}{1}

45\frac{1}{2} = \frac{91}{2}

\frac{1420}{1} ÷ \frac{91}{2}

Use mixed multiplication:

\frac{1420*2}{1*91}

= \frac{2140}{91}

Simplify:

= 31\frac{19}{91}

\boxed{[ \ Eclipsed \ ]}
