Is (5.7) a solution for the following system of equations?
y=2x-3
yr+2

Answer:

2 1/6 ft = 26 in

3 3/4 ft = 1 1/4 yrd

2 1/2 c = 1 1/4 p

3 2/3 yrs = 44 months

Step-by-step explanation:

Conversion:

ft to in = ft x 12

ft to yards = ft / 3

c to pints = c/2

yrs to months =  y x 12

Answer:

26 in, 1 1/4 yd, 1 1/4 pt, 44 months

Step-by-step explanation:

1ft=12in

12• 2 1/6=26in

3ft=1yd

3 3/4 ÷3= 1 1/4yd

2c=1pt

2 1/2 ÷ 2=1 1/4 pt

12months =1 year

3 2/3 • 12 = 44 months

Answer:I think the answer is  5/12.

Answer:

x=4

Step-by-step explanation:

13x+1 = 11x+9

13x-11x = 9-1

2x = 8

x = 4

Answer:

53 = 53

Step-by-step explanation:

13x+1=11x+9           13(4)+1=11(4)+9

13x=11x+8                52+1=44+9

2x=8                          53=53

x=4

Answer:

Y^= 1.767 + 0.6294X when rounded give s Y^= 1.77 +0.63X

b= 0.6294 rounded to 0.63

a= 1.77

The predicted lines are for each X and Y

3.340,3.96, 4.914, 5.228, and 5.543

Step-by-step explanation:

The data given is

Length (m)    Speed (m/s)              Predicted Line  

2.5                  3                                    3.340  

3.5                 4.5                                  3.96

5                   4.8                                  4.914

5.5                5.2                                 5.228

6                   5.5                                 5.543

The calculations are

                 Xsquare    XY   Y     X

                 6.25    7.5  3      2.5

                 12.25 15.75 4.5      3.5

                    25 24         4.8      5

                  30.25 28.6 5.2      5.5

                   36 33           5.5      6

Total       109.75 108.85   23         22.5

The estimated regression line of Y on X is

Y^ = a +bX

and two normal equations are

∑Y = na + b∑X

∑XY= a∑X + b∑X²

Now X`= ∑X/ n= 22.5/5=4.5

Y`= ∑Y/ n= 23/5= 4.6

b= n∑XY- (∑X)(∑Y) / n∑X²- (∑X²)

Putting the values

b= 5(108.85) - (23)(22.5)/ 5(109.75)- (22.5)²

b= 544.25-517.5/ 548.75-506.25

b= 26.75 /42.5

b= 0.6294

and

a= Y`- bX~= 4.6- 0.6294(4.5)= 4.6-2.823= 1.767

Hence the

desired estimated regression line of Y on X is

Y^= 1.767 + 0.6294X

Y^= 1.77 +0.63X

The estimated regression co efficient b= 0.6294 indicates that the values of Y increase by 0.6294 units for a unit increase in X.

Answer:1 / 15 of the pitcher

Step-by-step explanation:

The pitcher is 1/3 full and 5 people want to equally share it.

The equal amount is found by dividing 1/3 by 5:

= 1/3 ÷ 5

= 1/3 * 1/5

= 1/15 of the pitcher

Each person gets 1/5 of the pitcher

Answer:

Area = 21 un²

Explanation down Below!

Step-by-step explanation:

You don't need to worry about the 8 at all at this point

To find the area of a parallelogram you need to do base x height.

The height is 7, and the base of that height is 3.

7 x 3 = 21

Let me tell you why you do base x height.

if you cut out the triangle from the top and place it at the bottom it will become a rectangle.

The formula for a rectangle is base x height so this is why the formula works.

Answer:

x=37

Step-by-step explanation:

Complementary angles are a set of 2 angles that when added together, add up to 90. In order to solve for x, both angles have to be added and set to be equal to 90... but Jackie only used one of the angles, not both. The correct equation is: x+16+x=90

Answer:

Jackie forgot to add variable X

Step-by-step explanation:

Answer:

it is approximately 12.57meters

Answer:

12.56 meters

Step-by-step explanation:

The area of a circle is πr², where r is the radius of the circle.

First we square the radius, which is 2. 2²=4.

Now our area is 4π.

Using 3.14 for π, we can say the area is 4 × 3.14, which is equal to 12.56

Answer:

the arc length is 555.17 cm

Step-by-step explanation:

The equation to solve for the arc length is: s = rΘ, where r represents the radios and the Θ represents radians. In order to solve this you need to convert degrees into radians with the formula: radians = degrees ·

You want to find the distance the golf club travels when the golfer swings the club.

First you need to subtract 25° from 360°

360° - 25° = 335°

now you need to convert 335° into radians

radians = degrees ·

radians = 335° · you multiply 335° by

radians = 335/180 then you simplify

radians = 67/36

335° = 67[tex]\pi[/tex]/36

Now we plug everything we know into the equation s = rΘ

s = rΘ

s = 95 (67[tex]\pi[/tex]/36)        first multiply 67 by 3.14

s = 95 (210.38/36)    divide 210.38 by 36

s = 95 (5.843888889)   and multiply 95 by 5.843888889

s = 555.1694444  *remember to simplify to the nearest hundredth

s = 555.17 cm

Answer:

Katherine would have $109.54 more than Stella.

Step-by-step explanation:

Giving the following information:

Stella:

Initial investment (PV)= $6,100

Interest rate (i)= 0.065/12= 0.0054 per month

Number of periods (n)= 7*12= 84

Katherine:

Initial investment (PV)= $6,100

Interest rate (i)= 0.06625/4= 0.0167

Number of periods (n)= 7*4= 28

To calculate the future value, we need to use the following formula:

FV= PV*(1 + i)^n

Stella:

FV= 6,100*(1.0054^84)

FV= $9,589.5

Katherine:

FV= 6,100*(1.0167^28)

FV= $9,699.04

Difference= $109.54

Katherine would have $109.54 more than Stella.

Answer:

Number of 1/8 cups of sugar needed = 2

Number of 1/8 cups of whole wheat flour needed = 6

Number of 1/8 cups of all purpose flour needed = 4

Step-by-step explanation:

Recipes Kelly needs:

Sugar = 1/4 cups

Whole wheat flour = 3/4 cups

All purpose flour = 1/2 cups

She could only find her ⅛ cup measuring cup.

How many ⅛ cups will she need for each ingredient?

Number of 1/8 cups of sugar needed = cups of Sugar needed / 1/8 cups

= 1/4 ÷ 1/8

= 1/4 × 8/1

= 8/4

= 2

Number of 1/8 cups of sugar needed = 2

Number of 1/8 cups of whole wheat flour needed = cups of whole wheat flour needed / 1/8 cups

= 3/4 ÷ 1/8

= 3/4 × 8/1

= 24/4

= 6

Number of 1/8 cups of whole wheat flour needed = 6

Number of 1/8 cups of all purpose flour needed = cups of all purpose flour needed ÷ 1/8 cups

= 1/2 ÷ 1/8

= 1/2 × 8/1

= 8/2

= 4

Number of 1/8 cups of all purpose flour needed = 4

Answer:

[tex]x=\frac{9}{25}[/tex]

x = 0.36

Step-by-step explanation:

5x/3 + 2/5 = 1

5x/3 + 2/5 - 2/5 = 1 - 2/5

[tex]\frac{5x}{3} = 0.6[/tex]

5x/3 × 3 = 0.6 × 3

5x = 1.8

5x ÷ 5 = 1.8 ÷ 5

[tex]x=\frac{9}{25}[/tex]

x = 0.36
