Answer:

Step-by-step explanation:

BODMAS  used.

[(3+2)*10]÷5*2=[5*10]÷5*2 (inner parenthesis)

=50÷5*2 [next parenthesis]

=10*2  {division}

=20 {multiplication}

2)

2)(\frac{2[5+7]}{3*2})+6*8=(\frac{2*12}{3*2})+6*8\\\\=(\frac{24}{6})+6*8\\\\=4+6*8\\\\=4+48\\\\=52

3)15 - 8 + 18 ÷ 3*2 = 15 - 8 + 6*2

=15 - 8 + 12

= 7 +12

The equation of the line is y = -11x + 232

<h3>How to determine the equation?</h3>

The given parameters are:

Slope (m)= -11

Point (x1, y1) = (31, -109)

The linear equation is then calculated as:

y = m(x - x1) + y1

This gives

y = -11(x - 31) - 109

Evaluate the product

y = -11x + 341 - 109

Evaluate the like terms

y = -11x + 232

Hence, the equation of the line is y = -11x + 232

On Monday, Jayla raised $30 and Carlos raised $50.
gayaneshka [121]

Answer:

84 days

Step-by-step explanation:

You would use the LCM to solve this.

12 and 7 don't share any common factors other than 1,

so you would multiply 12 x 7, which gets you 84.

After 84 days they would have raised the same amount.

In 6 minutes, the descent will be
(4 ft/min)*(6 min) = 24 ft
