-5a + 15/2a - 25 = 53.2 + 21.8

dedylja [7]

Answer:

a= 40

Step-by-step explanation:

-5a + 7.5a - 25 = 53.2 + 21.8

add like terms on both sides: 2.5a - 25 = 75

add 25 on both sides: 2.5a = 100

divide both sides by 2.5: a = 40

The height of a giant redwood tree is 200 feet, and the height of an oak tree is 120 feet. Taking the height of the redwood tree

marta [7]

Answer:

$\% Change = \frac{|120-200|}{200} *100 = 40\%$

And the interpretation for this value is that the oak tree is have a height of 40% lower than the Redwood tree

Step-by-step explanation:

For this case we can calculate the % of change with the formula of relative change given by:

$\% Change = \frac{|New -Base|}{Base} *100$

For this case the Base value is 200 ft since represent the heigth of the redwood tree selected as the base

And the New value would be 120 who represent the height of the oak tree

If we replace into the formula we got:

$\% Change = \frac{|120-200|}{200} *100 = 40\%$

And the interpretation for this value is that the oak tree is have a height of 40% lower than the Redwood tree

(9p-5q)^2=can anyone plss answers this

DIA [1.3K]

Step-by-step explanation:

${(9p - 5q)}^{2}$

Hence according to ,

${(a - b)}^{2} = {a}^{2} - 2ab + {b}^{2}$

So,

${(9p)}^{2} - 2 \times 9p \times 5q + {(5q)}^{2}$

$81 {p}^{2} - 90pq + 25 {q}^{2} (ans)$
