Natalka [10]

Answer:

(11, 13)

Step-by-step explanation:

Carolyn's work is incorrect. Below is the correct solution:

Given:

$3x - 2y = 7$ ----› Equation 1

$y = x + 2$ -----› Equation 2

Substitute y = (x + 2) in equation 1

$3x - 2y = 7$ ----› Equation 1

$3x - 2(x + 2) = 7$ (substitution)

$3x - 2(x) -2(+2) = 7$ (distributive property)

[Note: this is where Carolyn made a mistake]

$3x - 2x - 4 = 7$

Collect like terms

$x - 4 = 7$

$x = 7 + 4$ (addition property of equality).

$x = 11$

Substitute x = 11 in equation 2

$y = x + 2$ -----› Equation 2

$y = 11 + 2$ (substitution)

$y = 13$

✅The solution to the system of equations would be:

Formula: multiply the value in meters by the conversion factor '3.2808398950132'.

So, 0.91 meter = 0.91 × 3.2808398950132 = 2.986 feet.

0.91 METER TO THE NEAREST FRACTIONS OR INTEGER OF FOOT:

3 feet (e* = 0.48%)

The latest values above are alternative ones for 0.91 meter. They are represented in the form of usable fractions (1

To calculate a meter value to the corresponding value in feet, just multiply the quantity in meter by 3.2808398950131 (the conversion factor).

Here is the formula:

Value in feet = value in meter × 3.2808398950131

Suppose you want to convert 0.91 meter into feet. Using the conversion formula above, you will get:

Value in feet = 0.91 × 3.2808398950131 = 2.986 feet
