Jerry scored 581 points by collecting 7 coins. In all, how many coins does Jerry have to collect to score a total of 996 points? Solve using unit rates.

Answers

Answer:

12 coins

Step-by-step explanation:

Points scored by collecting 7 coins = 581

Number of coins required to collect 996 points

Let Number of coins = c

7 coins = 581 points

c coins = 996 points

Cross multiply :

581 * c = 996 * 7

581c = 6972

Divide both sides by 581

581c / 581 = 6972 / 581

c = 12

Hence, number of coins required to collect 996 points is 12

Solve each system of equations.
2x- 4y = 20
x=4

Answers

Answer:

(x,y)=(4,-3)

Step-by-step explanation:

2x- 4y = 20

x=4

Substitute the value of x

2*4-4y=20

Solve equation

y=-3

A possible solution is

(x,y)=(4,-3)

Check the solution

2*4-4*(-3)=20

4=4

Simplify

20=20

4=4

The ordered pair is the solution

The solution of the given system of equations is y = -3.

What is the equation?

A formula known as an equation uses the same sign to denote the equality of two expressions.

In another word, the equation must be constrained with some constraints.

For example 5x + 4y = -8

Given the set of equations,

2x- 4y = 20

x=4

By substitution,

2(4) - 4y = 20

8 - 4y = 20

-4y = 20 - 8

-4y = 12

By multiplying by -1 both sides

4y = -12

By dividing 4 both sides

y = -3

Hence "The solution of the given system of equations is y = -3".

Tiffany is filling her daughter’s pool with water from a hose. She can fill the pool at a rate of 1/10 gallon/seconds.How many gallons of water can she fill in 50 seconds

Answers

Answer:

5 gallons

Step-by-step explanation:

If she can do 1/10 gallon per seconds, that means she can do 5/50.

You can write it as this ratio:

1/10 = x/50.

You know that 10 * 5 = 50.

Since it is a constant ratio, it has to be 1 * 5 = x

Since 1 * 5 = 5, Tiffany can fill the pool 5 gallons per 50 seconds.

Actually Welcome to the Concept of the Trigonometry.

here, we use the Linear pair property of the adjacent angles.

We know that, all the adjacent angles in a linear pair add to get 180°

so we get as,

=> (n+6) +90°+(2n+3) =180°

=> (n+6) +(2n+3) =180-90

=> 3n+9 = 90

=> 3n= 90-9

=> 3n = 81

hence, n = 81/3

=> n = 27°

thus the value of n is 27° .
