What is 20% off of £1.85? ^_^

Answers

$p\%=(p)/(100)\n\n20\%=(20)/(100)=0.2\n\n20\%\ of\ \£1.85\ is\ 0.2\ *\ \£1.85=\£0.37$

£1.85 ________ 100 %
x ________ 20 %

100x = 20 . 1,85
100x = 37
x = 37 / 100
x = 0,37

is £0,37 !

What are the steps to solving the inequality 3b + 8 ≥ 14

Answers

Answer:

The solution of the given inequality $3b+8\geq 14$ is: $[2, \infty)$

Step-by-step explanation:

Given the inequality equation: $3b+8\geq 14$

Subtraction property of equality states that you subtract the same number to both sides of an equation.

Subtract 8 to both sides of an equation.

$3b+8-8\geq 14-8$

Simplify:

$3b\geq 6$

Division property of equality states that you divide the same number to both sides of an equation.

Divide both sides by 3 we get;

$(3b)/(3) \geq (6)/(3)$

Simplify:

$b\geq 2$

therefore, the solution of the given inequality is: $b\geq 2$ or $[2, \infty)$

3b+8≥14
Subtract 8 from both sides
3b≥14-8
3b≥6
Divide both sides by 3
b≥6/3
b≥2

At a school supply store, binders cost $5 and pencil pouches cost $2. In one day, 42 of these items are sold for total sales of $144. Which system represents this (b represents binders and p represents pencil pouches), and how many binders were sold?

Answers

Answer:

Part 1) The system of equations that represent this situation is equal to

b+p=42 and 5b+2p=144

Part 2) 20 binders were sold

Step-by-step explanation:

Let

b -----> the number of binders sold

p -----> the number of pencil pouches sold

Part 1)

we know that

The system of equations that represent this situation is equal to

b+p=42

5b+2p=144

Part 2) How many binders were sold?

we have

b+p=42

p=42-b ------> equation A

5b+2p=144 -----> equation B

substitute equation A in equation B

5b+2(42-b)=144

5b+84-2b=144

3b=144-84

3b=60

b=20 binders
