What is -11 + 3(b + 5) = 7

IRISSAK [1]

Answer:

b=1

Step-by-step explanation:

$\sf -11 + 3(b + 5) = 7$

<u>First, let's regroup, terms,</u>

$\sf 3(b+5)-11=7$

<u>Add 11 to both sides,</u>

$\sf 3(b+5)=7+11$

<u>Simplify, 7+11 = 18,</u>

$\sf 3(b+5)=18$

<u>Now, divide both sides by 3,</u>

$\sf b+5=\frac{18}{3}$

<u>Simplify, 18/3 = 6,</u>

$\sf b+5=6$

Subtract 5 from both sides,

$\sf b=6-5$

$\sf b=1$

Hope it helps! :)

The population of a certain country is approximated by the following equation, where x is the number of years since 1980 and P i

marissa [1.9K]

Answer:

In 2010 the population become 206,123,000.

Step-by-step explanation:

Consider the provided equation.

$P=2.748x + 126.199$

Where P represents the population in millions.

We need to determine the year in which the country had population of 206,123,000.

As P is in millions so divide 206,123,000 by one million.

$\frac{206,123,000 }{1,000,000}= 206.123$

Substitute P = 206.123 in above equation.

$206.123=2.748x + 126.199$

$79.924=2.748x$

$x=\frac{79.924}{2.748}$

$x=29.08$

30 year from 1980 the population become 206,123,000.

In 2010 the population become 206,123,000.

The longer base of a trapezoid is 8 ft. The longer base of a similar trapezoid is 13 ft. The area of the smaller trapezoid is 24

Licemer1 [7]

Answer:

390 ft²

Step-by-step explanation:

The longer base of a trapezoid is 8 ft. The longer base of a similar trapezoid is 13 ft. The area of the smaller trapezoid is 240 ft² What is the area of the larger trapezoid?

We solve the above question using proportion

(Longer base/Area of trapezoid) smaller trapezoid = (Longer base/Area of trapezoid) bigger trapezoid

Let the the Area of the bigger trapezoid = x

Hence,

= 8ft/240ft = 13ft/x ft

Cross Multiply

8ft × x = 240ft × 13ft

x = 240ft² × 12 ft/8 ft

x = 390 ft²
