589/15.50 is 38

The answer is 38 hours

1. there are two methods to solve this system

I.substition

from the first relation we can deduct

2a-b=4

2a=4+b

a=(4+b)/2

now we substitute a in the second relation

(4+b)/2+b=5

we multiply by 2

4+b+2b=10

3b=6

b=6/3=2

a+2=5

a=3

II.reduction

2a-b=4

a+b=5

we can add the two relations together

2a+a-b+b=4+5

3a=9

a=3

3+b=5

b=2

Answer:

Answer:  $50

Step-by-step explanation:

30 × 10 = 40 ft²  [garden area]

40 ÷ 25 = 1.6

1.6 ≈ 2

For the area of the entire garden, you need to buy two bottles of fertilizer.

25 × 2 = 50        [fertilization cost for the whole garden]

Answer:

slope:5/2

y-intercept:-9

Step-by-step explanation:

Answer:

2.5

Step-by-step explanation:

First, we need to change the equation into slope-intercept form.

5x-2y=18     Isolate the y by subtracting 5x on both sides.

-5x     -5x

-2y=-5x+18  Divide both sides by -2.

/-2   /-2

y=2.5x-9

The slope is the number next to x, so the slope is 2.5.

Hope this helps! Have a great day C:

Answer:

v= 17

Step-by-step explanation:

Start with the given equation.

19v – 18 = 16 + 17v

Move -18 to the other side, and swap it's sign.

19v = 16 + 18 + 17v

Move 17v to the other side and swap it's sign.

19v - 17v = 16 + 18

Combine like terms.

2v = 34

Divide by 2v.

v = 17

Answer:

v = 17

Step-by-step explanation:

Given

19v - 18 = 16 + 17v ( subtract 17v from both sides )

2v - 18 = 16 ( add 18 to both sides )

2v = 34 ( divide both sides by 2 )

v = 17

Answer:

Answer: 3/4 granola bars

Step-by-step explanation:

From the question, we are given the information that Davita brought 6 granola bars for herself and the 7 other girls in her camp group.

The fraction of a granola bar that each girl gets if they agree it equally would be the number of granola bars bought divided by the total number of girls which is 8. Therefore, the calculation would be:

= 6 ÷ 8.

= 3/4 granola bars

Each person gets 3/4 granola bars.

The fraction of a granola bar that each girl will get is 3/4

To get the fraction of a granola bar will each girl get, we will take the ratio of the total granola to total number of girls.

Given the following parameters

Total number of 6 granola bars

Total number of girls plus Davita is 8

Taking the required ratio;

Ratio = number of granola: total number of girls

Ratio = 6:8

Ratio = 3:4

Hence the fraction of a granola bar that each girl will get is 3/4

Answer: 97 stickers

Step-by-step explanation:

Marie has 87 stickers in her collection.

Each week she collects 5 and gives away 3.

The total number of stickers she gains per week is therefore:

= 5 - 3

= 2 stickers per week

In 5 weeks therefore, she would have collected:

= 2 * 5

= 10 stickers

Add that to the original number:

= 87 + 10

= 97 stickers

Answer:

Option C

Step-by-step explanation:

-3 is the y intercept so the graph should intersect at -3 on the y axis.

x is positive so the graph should point up.

Answer:

Option C

Step-by-step explanation:

By looking at the equation y = x - 3 we can see that the slope is positive (so the line will have an upward trend) and that the y intercept is - 3 (which mean the line will go through the y axis in that point. So now we have two following statement....

The only line following this statements is line C.

Answer:

0.6 feet

Step-by-step explanation:

We solve this question using the Trigonometric function of Tangent.

tan θ = Opposite/Adjacent.

Where:

Opposite = Height /Length of the ramp = ?

Adjacent = Distance from the base of the ramp = 4 feet

θ = 8.1°

Therefore,

tan 8.1° = x/4

Cross Multiply

x = tan 8.1 × 4

x = 0.5692843028 feet

Approximately = 0.6 feet

Length of the ramp = 0.6 feet.

Step-by-step explanation:

Answer:

93

Step-by-step explanation:

Let’s call the tens digit x and the unit digit y. From the question we know that x + y = 12 and that x = y^2, giving us the following system of equations:

x + y = 12

x - y^2 = 0

Let’s multiply the second one by -1, to get rid of one of the unknowns in the system.

x + y = 12

-x + y^2 = 0

By adding together the two, we get y^2 + y = 12. As that is a quadratic equation, let’s make it of the form Ay^2 + By + C = 0, so subtracting 12 from each side gives as y^2 + y - 12 = 0. Then let’s solve the quadratic equation to find out the two values of y we get out of it, one of which is legal in the above system of equations.

y = (-B +/- sqrt(B^2–4AC))/2A

This time, both A and B are 1, while C is -12. By entering them in the above formula, we get the inner part of the square root to be 49, and thus the square root to give 7. So solving y = (-1 +/- 7)/2 gives two alternatives, either y = -4 (impossible, as it has to be a digit, ie has to be between 0 and 9 inclusive) or y = 3.

Then let’s return to the system of equations, and as both digits appear without any modifiers in the first one, let’s use it to find x with. So x + 3 = 12, x = 12 - 3, x = 9.

As x is the tens digit and y the unit digit per how the variables were chosen, we can with confidence say that the number is 93.
