Answer:

hi if you want to solve fore x and y there must be 2 equations .

Step-by-step explanation:

so that you could solve them simultaneously

-7x + 2y = 4

here 2y - 4 = 7x

( 2y -4)/7 = x

Subtract 2 from both sides of the equation that gives you
-7x=4-2y
decide each term by -7 and simply that gives you
-7x/-7=4/-7+-2y/-7
cancel the common factor of -7
decide by 1 and that gives you
x=4/7+-2y/-7
simply each term
move the negative in front of the fraction....x=-4/7+-2y/-7
dividing two negative values results in a positive value
answer is x=-4/7+2y/7

A pack of red pens can be divided into equal shares among 3, 5, 6 and 9 teachers with no pen left over?

Ugo [173]

Answer:

90 red pens

Step-by-step explanation:

we need to find the least common multiple of the numbers 3 , 5 , 6 , 9

6 = 2 × 3

9 = 3²

then

LCM(3,5,6,9) = 2×5×3² = 2×5×9 = 90

The number 90 can be divided into 3 ,5 ,6 ,9 with no remainder

Therefore the pack must have 90 pens or a multiple of 90

For example 180 , 270 ...

The population of a community is known to increase at a rate proportional to the number of people present at time t. The initial

GREYUIT [131]

Answer:

P(0) = 7,917

Step-by-step explanation:

The population of the community is given by the following formula:

$P(t) = P(0)(1+r)^{t}$

In which P(0) is the initial population and r is the growth rate.

The initial population P0 has doubled in 5 years.

This means that

$P(5) = 2P(0)$

Which lets us find r.

$P(t) = P(0)(1+r)^{t}$

$2P(0) = P(0)(1+r)^{5}$

$(1+r)^{5} = 2$

Applying the 5th root to both sides

$1+r = 1.1487$

$r = 0.1487$

So

$P(t) = P(0)(1.1487)^{t}$

Suppose it is known that the population is 12,000 after 3 years.

With this, we find P(0)

$P(t) = P(0)(1.1487)^{t}$

$12000 = P(0)(1.1487)^{3}$

$1.5157P(0) = 12000$

$P(0) = \frac{12000}{1.5157}$

$P(0) = 7917$
