WHAT IS 5/9-5/18?!PLS HELP ME!!!!
IgorLugansk [536]

Answer:

5/18

Step-by-step explanation:

note: 5/9 is the same as 10/18   (we get this by multiplying both numerator and denominator by 2)

hence

5/9-5/18

= 10/18 - 5/18

= (10-5) / 18

= 5/18

What are the solutions to the equation y2 – 1 = 15?
aivan3 [116]

Answer:

The solution of y² - 1 = 15  is +4 and -4

Step-by-step explanation:

Given

y² - 1 = 15

Our solution goes thus;

Make y² the subject of formula

y² = 15 + 1

Add 15 to 1

y² = 16

Take square roots of both sides

√y² = √16

y =  √16

Note that the square root of 16 is either +4 or -4 because +4 * +4 = 16 and -4 * -4 = 16; So, we replace √16 with ±4 which means + or -4

y = ±4

y = +4 and -4

Hence, the solution of y² - 1 = 15  is +4 and -4

it costs $x for a round trip bus ticket to the mall. You have $24. Write an inequality to represent the greatest amount of money
Nataliya [291]

Answer: x + 18.99 \leq 24

Step-by-step explanation:

Since, the cost of bus fair = x dollars,

Also, a baseball cap which is $18.99 is needed to buy with the given money,

Hence, total expenditure = x + 18.99

While the given money for spending = 24 dollars,

That is, the expenditure can not be exceeded to $ 24.

Thus, the required inequality,

x + 18.99 \leq 24

The figures below are similar. What are a) the ratio of the perimeters and b) the ratio of the areas of the larger figure to the
iren [92.7K]
A) ratio of the perimeters is the same as ratio of corresponding sides, so:

\dfrac{P_1}{P_2}=k=\dfrac{22}{14}=\dfrac{11}{7}\approx1,57

b) ratio of the areas is equal to k² so:

\dfrac{A_1}{A_2}=k^2=\left(\dfrac{11}{7}\right)^2=\dfrac{121}{49}\approx2,47
