Gabrielle's age is two times Mikhail's age. The sum of their ages is 21 . What is Mikhail's age?

Answer:

( − 6 , 2 )

Step-by-step explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation.   (the points of intersection).

Answer:

y = 3x - 5

Step-by-step explanation:

3x-y=5

-3x     -3x

-y= -3x + 5

divide each number by -1

-y/-1 = y

-3x/-1 = 3x

5/-1 = -5

The equation 3x - y = 5 can be converted to slope-intercept form as follows: y = 3x - 5

Given is an equation 3x - y = 5, we need to convert it in slope-intercept form.

To convert the equation 3x - y = 5 into slope-intercept form (y = mx + b), where "m" represents the slope and "b" represents the y-intercept, we need to isolate the variable "y" on one side of the equation.

Let's rearrange the given equation step by step:

Starting with 3x - y = 5, we can begin by moving the term involving "x" to the other side:

3x - y + y = 5 + y

Simplifying:

3x = y + 5

Now, let's isolate "y" by subtracting "y" from both sides:

3x - y = y + 5 - y

Simplifying:

3x - y = 5

To eliminate the "y" term on the left side, we can add "y" to both sides:

3x - y + y = 5 + y

Simplifying:

3x = 5 + y

Next, let's rearrange the equation to have "y" on the right side:

3x = y + 5

We can write this equation as:

y = 3x - 5

Now the equation is in slope-intercept form (y = mx + b), where the slope "m" is 3, and the y-intercept "b" is -5.

Step-by-step explanation:

To start solving this problem, you need to figure out how many Pounds( I'll use lbs.) = 5 Tons( I'll use T).

2,000 lbs. = 1 T.

X 5               X 5

10,000 lbs. = 5 T.

Now we divide. That just means that if we know that 1 person( I'll use P) = 150, we just divide 5 T( 10,000 lbs.) by 150 lbs.

10,000/150=66.6666666667

It take him 7 hours to earn the money if he only does yardwork for his grandmother.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given that Leroy wants to buy a new racing bicycle that costs $168. He earns $24 for 3 hours of yardwork and he earns $48 for 4 hours of babysitting.

We need to find the time take to earn the money if he only does yardwork for his grandmother.

Thus, $24 for 3 hours of yardwork

24/3=8

Again, $48 for 4 hours of babysitting.

48/4=12

Now, 168/12=14

168/8=21

The time difference is;

21-14=7

Step-by-step explanation:

Bcs when u have a closed circle is when is less or equal to, and an open circle means greater/less to.  And you have a closed bcs is less or equal to. So u look in the answers, you can already take two answers out which are the 2 and the 3 bcs they are open circle. Then x ≥ 98.6, then x is bigger than the 98.6 so the arrow would go to the right. And the answer would be first one

(How to do that in an easier way, Look at this ≥, the pointy side is aiming in the right so the arrow will go always to the right, THIS ONLY WORKS WHEN THE LETTER IS IN THE LEFT {EX. y ≤ 19, the arrow will be pointing in the left.)

u will add all all what she spent

Answer:

It will cost Jane $21.00

Step-by-step explanation:

As, cost of 1 chocolate = x

The cost of 1 packet of chips = $3 + x

So no. Of 2 chocolate bars = x + x = 2x

And no. Of packet of chips = ($3+x) + ($3+x) + ($3+x) = 3(3+x) = 9+3x

So now = cost Of chocolate + cost of chips = $19

So = 2x + 9+3x = 9 + 5x

So 9 + 5x = $19

So 5x = $19 - 9 = $10

So 5x =10

x = 10/5

x = 2

So cost of 2 chocolate = 2x = 2($2) = $4

And 3 chip packet = 9+3x = 9+3($2) = 9+6 =$15

So now total = $4 + $15 = $19

Now for John = 2 chocolates and 3 packets of chips = $19

Now for Jane she has 3 chocolates and 3 packets of chips, so she has one more chocolate amd now we know that 1 chocolate = $2

So we will just add one more chocolate

So Jane will pay = $ 19 + $2 = $21

So it will cost Jane = $21:00

Answer:8/9

Step-by-step explanation:4/3 * 2/3=8/9

The simplification of the fraction 1 1/3 x 2/3 in the simplest form will be; 8/9

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We have been given the mixed fraction as;

[tex]1 \dfrac{1}{3} \times \dfrac{2}{3}[/tex]

First, we need to simplify the mixed fraction;

[tex]1 \dfrac{1}{3} =\dfrac{4}{3}[/tex]

Therefore, the product of the fraction will be;

4/3 x 2/3 = 8/9

Hence, the simplification of the fraction 1 1/3 x 2/3 in the simplest form will be; 8/9
