Answer:

x = 5

Step-by-step explanation:

Simplifying

6x + -3 = 3x + 12

Reorder the terms:

-3 + 6x = 3x + 12

Reorder the terms:

-3 + 6x = 12 + 3x

Solving

-3 + 6x = 12 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-3 + 6x + -3x = 12 + 3x + -3x

Combine like terms: 6x + -3x = 3x

-3 + 3x = 12 + 3x + -3x

Combine like terms: 3x + -3x = 0

-3 + 3x = 12 + 0

-3 + 3x = 12

Add '3' to each side of the equation.

-3 + 3 + 3x = 12 + 3

Combine like terms: -3 + 3 = 0

0 + 3x = 12 + 3

3x = 12 + 3

Combine like terms: 12 + 3 = 15

3x = 15

Divide each side by '3'.

x = 5

Estimate the part of the garden that is planted with tomatoes. Explain how you decided.
strojnjashka [21]

Answer:

Therefore tomatoes\hspace{0.1cm} patch = \frac{3}{8}\hspace{0.1cm}of\hspace{0.1cm} garden

Step-by-step explanation:

i) from the figure shown pumpkins and lettuce seem to make up half of the of the garden

ii) the other half of the garden seems to be tomatoes and cucumber.

iii) tomatoes seems to be 3 times that of cucumber.

iv) therefore we can say that tomatoes would make up three fourths of half of the garden which would equal to three eights of the garden.

tomatoes\hspace{0.1cm} patch = \frac{3}{8}\hspace{0.1cm}of\hspace{0.1cm} garden

ruslelena [56]

Answer:

<h2>a) approximately 133 graduates</h2><h2>b) approximately 120°</h2>

Step-by-step explanation:

a) the number of graduates planning to continue studying :

= (37 1/2% + 12 1/2% + 16 2/3%) × 200

=\frac{\left( 37\frac{1}{2} +12\frac{1}{2} +16\frac{2}{3} \right)  }{100} \times200

= (37.5 + 12.5 + 16.666666666667)×2

= 133.333333333334

…………………………………

b) the measurement of the angle representing those who plan to work :

= (360× 33 1/2)÷100

= (360× 33.333333333333)÷100

=119.999999999999
