What does this simplify to? 3+5.25 = 1 - 2.8x

ahrayia [7]

Answer:

-2.59 = x

Step-by-step explanation:

3+5.25 = 1 - 2.8x

Combine like terms

8.25 = 1-2.8x

Subtract 1 from each side

8.25 -1 = 1-1-2.8x

7.25 = -2.8x

Divide each side by -2.8

7.25/-2.8 = -2.8x/-2.8

-2.589285714 = x

Square NOPQ is dilated by a scale factor of to form square N'O'P'Q'. Side N'O' measures 4. What is the measure of side NO?

KIM [24]

$\begin{gathered} \text{NOPQ was dilated to N'O'P'Q'} \\ \text{The scale factor is }\frac{2}{3} \\ N^{\prime}O^{\prime}=4 \\ N^{\prime}O^{\prime}=\frac{2}{3}NO \\ 4=\frac{2}{3}NO \\ \text{cross multiply} \\ 12=2NO \\ NO=\frac{12}{2} \\ NO=6 \end{gathered}$

sergij07 [2.7K]

Answer:

The area of the end is 1755.44 ft²

Therefore, the maximum error in calculating area of the end is 8.3592

Step-by-step explanation:

Consider the provided information.

The length of the base is measured to be 35 feet, with a maximum error in measurement of 1 inch,

$1\ inch = \frac{1}{12}\ feet$
