The width of a rectangle is 4 less than half the length. If represents the length, which equation could be used to find the width, w?

Answers

Answer 1

Answer: w = width
l= length

w = l/2 - 4

l/2 repreaents half the length
- 4 is 4 less than half the length

Answer 2

Answer:

The equation of the width(w) is l/2-4.

What is the equation ?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

According to the question

length is represented by l

width is represented by w

so w=l/2-4.

Therefore, he equation of the width(w) is l/2-4.

If 6m + 4 = 8m, then 4m

Answers

6m + 4 = 8m

Subtract 6m from each side:

4 = 2m

Multiply each side by 2 :

8 = 4m

$6m + 4 = 8m$
$4 = 2m$
$2 = m$

$4m$
$4(2)$
$8$

$4m = 8$

If a/4 = 9/a, then
a²=36
4a = 9a
a + 4 = 9 + a
a - 4 = 9 - a

Answers

Answer:

Option A is correct.

The given expression : $(a)/(4) = (9)/(a)$ then;

$a^2 = 36$

Step-by-step explanation:

Given the expression: $(a)/(4) = (9)/(a)$

Cross multiplication the given expression following steps are as follow;

Multiply numerator of the left-hand fraction by the denominator of the right-hand fraction

Also, Multiply numerator of the right-hand fraction by the denominator of the left-hand fraction.

then, set the two products equal to each other.

Using cross multiplication, on the given expression;

$(a)/(4) = (9)/(a)$

First multiply the numerator of the left hand fraction(i.e,a ) by the denominator of the right hand fraction (i,e a)

we have;

$(a * a)/(4) = 9$

Simplify:

$(a^2)/(4) =9$ [1]

now, multiply numerator of the right-hand fraction( i.e, 9) by the denominator of the left-hand fraction (i.e, 4 ) in [1]

we have;

$a^2 = 9* 4$

Simplify:

$a^2 = 36$

Therefore, the given expression is equal to: $a^2 = 36$

The answer is a²=36

$(a)/(4) = (9)/(a)$
Multiply both sides of the equation by 4a:
$4a*(a)/(4) =4a* (9)/(a) \n a*a=4*9 \n a^(2) =36$

Sean bought a laptop and a printer. He sold both items for £1,500 getting £1,350 just for the laptop. Sean made a 24% profit on the cost of the printer. What was the cost of the printer? Give your answer to 2 decimal places.

Answers

Answer:

Step-by-step explanation:

Sean purchased a printer and laptop

He sold both for 1,500

He sold the laptop at 1,350

Therefore the cost of the printer can be calculated as follows

1500-1350

= 150

24/100×150

= 0.24×150

= 36

Henve the cost of the printer is £36
