Solve this equation v^2 - 2v = 3

Answers

Answer:

v = − 1 or v = 3

Step-by-step explanation:

Let's solve your equation step-by-step.

[tex]v^{2}[/tex] − 2v = 3

Step 1: Subtract 3 from both sides.

[tex]v^{2}[/tex]  − 2v − 3 = 3 − 3

[tex]v^{2}[/tex]  − 2v − 3 = 0

Step 2: Factor left side of equation.

( v + 1 ) ( v − 3 ) = 0

Step 3: Set factors equal to 0.

v + 1 = 0 or v − 3 = 0

v = −1 or v = 3

At a baseball game henry bought 5 hot dogs and three bags of chips for $14.82. Scoot bought 7 hotdogs and 6 nags of chip for $22.98. Find the cost of each hotdog and bag of chips

Answers

2.25

per hot dog

1.19

per bag o' chips

Explanation:

5x +3y = 14.82

7 x+6y = 22.89

− 10x−6y = −29.64

7 x+6y = 22.89

−3x  = −6.75

x=2.25

5⋅2.25+3y = 14.82

3y = 14.82  − 11.25

y = 3.57 /3  = 1.19

The cost of each hot dog and bag of chips is $2.22 and $1.24

What is a system of equations?

A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Given that, At a baseball game Henry bought 5 hot dogs and three bags of chips for $14.82. Scoot bought 7 hot dogs and 6 nags of chip for $22.98.

Let the unit prices of hot dogs and chips be h and c respectively,

Therefore, establishing the equations,

5h + 3c = 14.82...(i)

7h + 6c = 22.98....(ii)

Multiply eq(i) by 2 and subtract eq(ii) by eq(i)

(10h + 6c = 29.64) - (7h + 6c = 22.98)

3h = 6.66

h =2.22

Put h = 2.22 in eq (i)

5(2.22) + 3c = 14.82

11.1 + 3c = 14.82

3c = 3.72

c = 1.24

Hence, the cost of each hot dog and bag of chips is $2.22 and $1.24

The tyre of a car wheel has an outer diameter of 30 cm . How many times will the wheel rotate on a journey of 5 km

Answers

Answer:

5305.1647 times

Step-by-step explanation:

The Circumference of a circle : πd

d = diameter of circle = 30 cm

Circumference of wheel = π * 30cm = 94.247779 cm

1km to cm

1km = 100000cm

5 km = 500000 cm

Hence, number of times wheel rotate on a 5km journey :

500000 cm / 94.247779 cm

Explanation:

Cross multiply the following:

[tex] \frac{x}{100} = \frac{71.76}{138} [/tex]

x times 138 = 138x

100 times 71.76 = 7,176

Margaret and Kevin both have to write an expression that is equivalent to 6 to the power of -4. Part A Who is correct? Part B What is a possible error made by the incorrect student?
Margaret writes 6 x (1/6 to the power of 5)
Kevin writes 1/6 x (6 to the power of 4)
Please help

Answers

Answer:

Margret is correct, Kevin is wrong.

Step-by-step explanation:

6^-4 can be written as (1/6)^4

By taking (1/6)^5 times you have (1/6)(1/6)(1/6)(1/6)(1/6), multiplying by 6 would cancel one of those (1/6ths) out. Meaning you would be left with (1/6)^4 or 6^-4

Kevin is wrong because taking 6^4 would not be the same as 6^-4, 6^4= 1296, multiplying that by 1/6 would not give you the same value as 6^-4. His mistake was that he did not take the reciprocal of 6^-4 and incorrectly removed a negative.

In one basketball game, Zaid made 7 two-point and three-point baskets to score 17 points. Let x represent the number of two-point baskets, and y represent the number of three-point baskets. This situation can be represented by the system x+y=7 and 2x+3y=17 . How many of each type of basket did Zaid make?

Answers

Answer:

y =three point score =  3

x = two point score = 4

Step-by-step explanation:

this question can be solved using simultaneous equation

x + y = 7  eqn 1

2x + 3y = 17  eqn 2

Multiply eqn 1 by 2 to derive eqn 3

2x + 2y = 14 eqn 3

Subtract eqn 3 from 2 :

y = 3

Substitute for y in eqn 1

x + 3 = 7
