Answer:

d - 7

Step-by-step explanation:

The word "difference" tells us that we will be using subtraction. Also, subtraction is not the same if you reverse the terms like, x - 2 and 2 - x are not the same. In your question it say "d and 7" so that's the order we use in the algebraic expression.

A country has a total biocapacity of 6.21 ha/person, a biocapacity of grazing land of 0.85 ha/person, and a biocapacity of fores

leonid [27]

Answer:

44.8 %

Step-by-step explanation:

Let p = the number of people. Then

Total biocapacity = 6.21p ha

Grazing biocapacity = 0.85p ha

Forest biocapacity = <u>2.53p </u>

Grazing + forest = 2.78p ha

$\text{Percent grazing + forest} = \dfrac{\text{grazing + forest}}{\text{Total}} \times 100 \, \% \\\\= \dfrac{\text{2.78p ha}}{\text{6.21p ha}} \times 100 \, \% = \mathbf{44.8 \,\%}$

lin and pazi are think of a number lins number is 7 more than pazi number the sum of the number is 49 whats pazi number

Lesechka [4]

Lin's number = l
pazi's number = p

l = p + 7
p = p

p + 7 + p = 49

2p + 7 = 49

2p + 7 (-7) = 49 (-7)

2p = 42

2p/2 = 42/2

p = 21

l = p + 7

l = 21 + 7

l = 28

pazi is 21 years old, Lin is 28 years old

hope this helps
