Need some help with the question in the image

goldfiish [28.3K]

Step-by-step explanation:

cost of 1 kg of jam = x

cost of 1 kg of butter = y

3x + 2y = 29 .....1

6x + 3y = 54 .....2

.....1 × 2 both sides of equation

6x + 4y = 58 .....3

.....3 - ......2

y = 4

replace y = 4 in 1......

3x + 8 = 29

x = 7

Solve for n <br><br> 11/6=n+7/9<br><br><br> (Plz no trolling; will mark brainiest)

xxTIMURxx [149]

Answer:

$n=\frac{19}{18}$

Step-by-step explanation:

Ir order to find the value of n in the given linear equation: $\frac{11}{6} = n + \frac{7}{9}$ you have to perform the properties of equalities to obtain an equivalent equation.

You have to perform these properties in each side of the equation.

Applying the subtraction property (which is the subtraction of the same number to each side of the equation):

Adding $\frac{7}{9}$ to each side:

$\frac{11}{6} - \frac{7}{9} = n + \frac{7}{9} - \frac{7}{9}$

This way you can obtain the value of n

$\frac{11}{6} - \frac{7}{9} = n$

Solving the subtraction of the fractions and simplifying:

$\frac{(11)(9)-(7)(6)}{(6)(9)} = n\\\frac{57}{54} = n\\n=\frac{19}{18}$

Left to Right

<u>Algebra II</u>

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-2, -5)

Point (3, -6)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance<em> d</em>

Substitute in points [DF]: $\displaystyle d = \sqrt{(3--2)^2+(-6--5)^2}$
(Parenthesis) Simplify: $\displaystyle d = \sqrt{(3+2)^2+(-6+5)^2}$
(Parenthesis) Add: $\displaystyle d = \sqrt{(5)^2+(-1)^2}$
[√Radical] Exponents: $\displaystyle d = \sqrt{25+1}$
[√Radical] Add: $\displaystyle d = \sqrt{26}$
