Answer:

5 weeks

Step-by-step explanation:

Substract 319.5 (the amount he has to save) to the amount he has already saved, which is 21.95. Now the constant amount of change is 63 dollars each week so divided it by that. So the equation should be (319.5-21.95) and divide all that by 63 to get 4.72 or rounded to the nearest number, is 5.

The value of x = 1/2 , y = 3 of the simultaneous equation.

"Simultaneous Equation is an essential Chapter in the Algebra branch of Mathematics. There are times when you come across two or more unknown quantities and two or more equations relating to them. These are called Simultaneous Equations. When you are asked to solve such equations, you must find values of the unknowns which satisfy all the given equations at the same time. They are Simultaneous Equations because the equations are solved at the same time. Simultaneous Equations need algebraic skills to find the values of letters within two or more equations."

Given, The equations

[tex]2x + 3y = 10[/tex] ----------- eq 1

[tex]4x - y = -1[/tex] ------------ eq 2

multiplying eq 1 by 2

[tex]4x + 6y = 20[/tex] ----------- eq 3

now subtracting eq 3 from eq 2

we get, [tex]7y = 21[/tex]

y = 3 and x = 1/2

Hence, the values of x and y = 1/2, 3 respectively.

Answer:

13/17, 20/17

Step-by-step explanation:

3x + 4y = 7 --- Equation 1

Equation 1×5:

15x + 20y = 35 --- Equation 2

------------------------------------------------------------------------------------------------------------

8x + 5y = 12 --- Equation 3

Equation 3×4:

32x + 20y = 48 --- Equation 4

------------------------------------------------------------------------------------------------------------

Equations 4-2:

32x + 20y - 15x - 20y = 48 - 35

17x = 13

x = [tex]\frac{13}{17}[/tex]

Substitute x = [tex]\frac{13}{17}[/tex] into Equation 1:

3x + 4y = 7

3([tex]\frac{13}{17}[/tex]) + 4y = 7

[tex]\frac{39}{17}[/tex] + 4y = 7

4y = 7 - [tex]\frac{39}{17}[/tex]

    = [tex]\frac{119}{17}[/tex] - [tex]\frac{39}{17}[/tex]

    = [tex]\frac{80}{17}[/tex]

y =  [tex]\frac{80}{17}[/tex] ÷ 4

y = [tex]\frac{20}{17}[/tex]

Thus, x = [tex]\frac{13}{17}[/tex], y = [tex]\frac{20}{17}[/tex].

( [tex]\frac{13}{17}[/tex], [tex]\frac{20}{17}[/tex])

Answer:

10:25 AM

Step-by-step explanation:

Solving the question above, we are total that:

On Wednesday at camp, Melissa went for a hike at 6:30 A.M. The hike took 2 hours and 55 minutes. As soon as she got back from the hike, Melissa played volleyball for 1 hour.

The time that Melissa finished playing volleyball is calculated as:

6:30AM + 2 hours 55 minutes + 1 hour

= 6:30 am + 3 hours 55 minutes

= 9:85 minutes

60 minutes = 1 hour

85 minutes = 1 hour 25 minutes

= 10:25 AM

Hence: Melissa would finish playing volleyball at 10:25 AM

Answer:

51 and  -27

Step-by-step explanation:

The sum of two numbers is 24 and their difference is 78. What are the two numbers? Let's start by calling the two numbers we are looking for x and y.

The sum of x and y is 24. In other words, x plus y equals 24 and can be written as equation A:

x + y = 24

The difference between x and y is 78. In other words, x minus y equals 78 and can be written as equation B:

x - y = 78

Now solve equation B for x to get the revised equation B:

x - y = 78

x = 78 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 24

78 + y + y = 24

78 + 2y = 24

2y = -54

y = -27

Now we know y is -27. Which means that we can substitute y for -27 in equation A and solve for x:

x + y = 24

x + -27 = 24

X = 51

Summary: The sum of two numbers is 24 and their difference is 78. What are the two numbers? Answer: 51 and -27 as proven here:

Sum: 51 + -27 = 24

Difference: 51 - -27 = 78

Answer:

The numbers are 27 and 51

Explanation

x - y = 24

x + y = 78

Add together the equations

2x = 102

x = 51

Put into equation

51 - y = 24

27 = y

Answer:113

Step-by-step explanation:

I’m not really sure but the exterior angle lies on a straight line meaning that it has to amount to 180 degrees. 67 + x =180 so x = 180-67 which is 113. But I’m not entirely sure bout this.

67-180=113

x=113

lx< 25

2) lx-11+1>15

+11 on both sides

lx+1>26

-1 on both sides

lx> 25

Answer:

Both absolute values would need to be isolated first.

You would need to write a compound inequality for each.

Both compound inequalities would compare

x – 1 to  –15 and 15.

The inequality with “<” would use an “and” statement, while the “>” would use an “or” statement.

Answer:

y=5/2x-16

Step-by-step explanation:

First, we want to find the slope of the original line.

m= -4+8/-1-9

m= 4/-10

m= -2/5

Because we want the perpendicular bisector, we will need the slope to be the opposite reciprocal. Therefore, our slope is

m=5/2

Now, we want to find the midpoint of the line.

9-1/2

8/2=4

-8-4/2

-12/2= -6

So, the midpoint is (4,-6)

Using the information we have, we now can find b.

-6=5/2(4)+b

-6=10+b

-16=b

That gives us our equation

y=5/2x-16

Answer:

540 miles

Step-by-step explanation:

-To solve what the distance is, you can use the formula:

d = st, where the distance is equal to the speed times the time.

-Plug the values into the formula (60mph is the speed, and 9 hours is the time):

d = 60(9)

-Solve it to get:

d = 540

-So, distance = 540 miles
