Answer:

[tex]Polynomial = 5x+ 2[/tex]

Step-by-step explanation:

Given

[tex]Weights = 3 + 4x[/tex]

[tex]Treadmill = 9x + 5[/tex]

Required

Polynomial that represents time spent running treadmill than weight lifting

To do this, we simply subtract weights from treadmill

i.e.

[tex]Polynomial = Treadmill - Weights[/tex]

[tex]Polynomial = 9x + 5 - (3 + 4x)[/tex]

[tex]Polynomial = 9x + 5 - 3 - 4x[/tex]

[tex]Polynomial = 9x - 4x+ 5 - 3[/tex]

[tex]Polynomial = 5x+ 2[/tex]

Answer:

1.30g

Step-by-step explanation:

The mass of 8 seed pods is equal to 10.4g.

10.4g = 8 pods

Total mass / Total pods = Individual pod weight

10.4g / 8 pods = 1.30g per pod

Lets check our work to confirm:

1.30g x 8 pods = 10.4g

Answer:

X=-2

Y=0

Step-by-step explanation:

X+y=-2 = x=-2-y

3x+4y=-6

3(-2-y)+4y=-6

-6-3y+4y=-6

y=0

x+3(0)=-2

x=-2

Answer:

[tex]\boxed {\boxed {\sf (-2,0)}}[/tex]

Step-by-step explanation:

To solve by substitution we must first isolate 1 variable in an equation.

Let's use the first equation.

[tex]x+3y= -2[/tex]

Subtract 3y from both sides to isolate the variable x.

[tex]x+3y-3y= -2 -3y[/tex]

[tex]x= -2 -3y[/tex]

Now we can substitute the expression (-2-3y) in for x in the second equation.

[tex]3x+4y= -6[/tex]

[tex]3(-2-3y)+4y= -6[/tex]

Distribute the 3. Multiply each term inside the parentheses by 3.

[tex](3*-2)+ (3*-3y)+4y=-6\\-6-9y+4y=-6[/tex]

Combine the like terms on the left side.

[tex]-6-5y= -6[/tex]

Add 6 to both sides to isolate the variable.

[tex]-6+6-5y=-6+6\\-5y=0[/tex]

Divide both sides by -5.

[tex]-5y/-5=0/-5 \\y=0[/tex]

Now we know that y is equal to 0 and can substitute it into the first equation and find x.

[tex]x+3(0)=-2[/tex]

[tex]x+0=-2 \\x= -2[/tex]

x is equal to -2 and y is equal to 0.

Answer:

The answer is 3

Step-by-step explanation:

Here's my explanation. So all you have to do is divide 6 by 2 and we ALL KNOW FOR AFACT what 6/2 right? And its 3 so there ya go!!!

Answer:

12 games

Step-by-step explanation:

Let x be the number of games played

The y won 75% of the games played and that was 9

x * 75% = 9

Change to decimal form

x * .75 = 9

Divide each side by .75

x * .75 /.75 = 9/.75

x =12

They played 12 games

Answer:

Step-by-step explanation:

75g/100=9

g=900/75

g=12

% is read as percent, and cent means 100.

In this case 6% is 6 out of 100 or 6/100.

so 6%*350=350*6/100=21

The second case its 25%*80=25/100*80=20

The third case, its 35*15/100=5.25

Answer:

50

Step-by-step explanation:

[tex]\boxed{distance \: between \: 2 \: points = \sqrt{(y1 - y2)^{2} + (x1 - x2) {}^{2} }}[/tex]

Distance between the 2 points

[tex] = \sqrt{( - 3 - 2) {}^{2} +( - 1 - 4) {}^{2} } [/tex]

[tex] = \sqrt{( - 5)^{2} + ( - 5)^{2} } [/tex]

[tex] = \sqrt{25 + 25} [/tex]

[tex] = \sqrt{50} [/tex]

Thus, the number that goes beneath the radical symbol is 50.

Answer:

Hey mate.....

Step-by-step explanation:

This is ur answer....

2a2 + (-1×2-a) +36

= (2×5×2) + (-1×2-5) + 36

= 20 + (-7) + 36

= 56 + (-7)

= 56 - 7

= 49

Three angles are given to us and we all know that the sum of four sides of quadrilateral is 360⁰

so

133⁰ + 147⁰ + 47⁰ + x = 360⁰

x = 380⁰ - 367⁰

x = 13⁰

Answer:

−12[tex]x^{2}[/tex]+3x+9

Step-by-step explanation:

=(3)(3x)+(3)(3)+−12x2+−6x

=9x+9+−12x2+−6x

Answer:

After 15 weeks, Gia and Micheal will both have $50 in savings.

Step-by-step explanation:

For Gia:

We start at $20 since she already has $20 in savings, we will add that to how much Gia will receive in 15 weeks.

Gia receives $2 a week and therefore in 15 weeks she will have $50.

= 2x15 = $30

= 30+20 =  $50

For Micheal:

We start at $5 since he already has $5 in savings, we will add that to how much Micheal will receive in 15 weeks.

Micheal receives $3 a week and therefore in 15 weeks he will receive $50

= 3x15 = $45

= 5+45 = $50
