Answer:

Ameliorate retort, pertaining to preceding albeit contingent interrogate proximates subject to x = 12.

Step-by-step explanation:

Availing, exploiting, albeit maneuvering the Mathematic convention, Order of Operations (OO), the contiguous albeit proximate equation may ascertain as the preeminent imminent:

Groups: Not identified.

Exponents: Not identified, disparaging ₁.

Multiplication: Derived, pertaining to subtraction, 4 · (7/4x) = 4 · 21 7x = 84

Division: Derived, pertaining to multiplication, 7x = 84 ⇒ x = 12

Addition: Aggregate constants ⇒ 5/2x = 3/4x +21

Subtraction: Abate algebraic groups ⇒ 7/4x = 21

Answer:

Step-by-step explanation:

When the population drops by 4.5%, there will be (1 - 4.5%) = 0.955 portion of the original population staying. When it happens 3 years in a row with an original population of 937, there will be:

Jane and Mo have 528 parcels to

Temka [501]

Answer:

Jane gave 132 parcels to Mo.

Step-by-step explanation:

Given total number of parcels both Jane and Mo have = 528.

Let the number of parcels having Jane and Mo be x and y respectively.

$Therefore\ x\ +\ y\ =\ 528\ equation\ 1\\x\ =\ 3y\ equation\ 2$

Now let the number of parcels Jane gives to Mo be z.

$So\ according\ to\ question\ x-z = y+z\\3y-z=y+z(from\ equation\ 2)\\2y=2z\\y=z$

$x+y=528\\3y+y=528\\4y=528\\y=132\\y=z=132$

So the number of parcels Jane give to Mo is 132.

Solve the system of linear equations below.

sergiy2304 [10]

Answer:

Step-by-step explanation:

Let's use the addition/elimination method to solve this. If we multiply the first equation through by -1 we can eliminate the x terms. Doing that gives us:

-x + 3y = 3

x + 3y = 9

The x's subtract each other away leaving us with

6y = 12 so

y = 2.

Now we will plug in 2 for y in either of the original equations to solve for x:

x + 3(2) = 9 and

x + 6 = 9 so

x = 3

The coordinate for the solution is (3, 2) or x = 3, y = 2

The second choice down is the one you want.
