Answer:

a) y = 2x - 3 and y = -2x - 3

Step-by-step explanation:

Here x is the larger number and y is the smaller number,

Given,

The difference between twice of x, and y is 3.

That is,

2x - y = 3\implies y = 2x - 3-----(1)

And, The sum of twice of x and y is –3,

2x + y = -3\implies y = -2x - 3-----(2)

Hence, from equation (1) and (2),

We can say that,

Option a is correct.

3³+1x9+12 answer please, I really think it's 48.
UNO [17]

Answer:

You are correct the answer is 48.

Step-by-step explanation:

To begin solving this question you would want to start simplifying it to make it more understandable.

3^3 is 27 which now gives you 27 + 1 x 9 +12 which makes it easier to solve.

Then you would take 1 x 9 = 9 (multiply left to right)

Now it is simple addition

27 + 9 + 12 = 48

Hopefully this helps.

Tickets to a local circus cost $5 for students and $8 for adults. A group of 9 people spent a total of $60. How many adults were
S_A_V [24]

Answer:

5

Step-by-step explanation:

You need to set up and solve a system of linear equations here.

Let s and a represent the number of students and adults respectively.

Then s + a = 9, and s = 9 - a.

Total ticket cost for the adults was ($8/adult)(a)

and for the students ($5/student)(s).

Total cost of the tickets was then  ($8/adult)(a) + ($5/student)(s) = $60.

Then our system of linear equations is:

8a + 5s = 60

 a  +  s  = 9, or s = 9 - a.  Substituting 9 - a for s, we get:

8a + 5(9 - a) = 60.

Then 8a + 45 - 5a = 60, or 3a = 15.

Solving for a, we get a = 5.

Solving for s using s = 9 - a, we get   s = 9 - 5, or s = 4.

There were 5 adults in the group (and 4 students).

A boat leaves a.M. Marina at 7 AM traveling at 3.4 knots bearing is N38°E the boat docks on an island at 2pm how far north of th
Jlenok [28]

Answer:

The distance between the docks & island is 44.07 km.

Step-by-step explanation:

Speed of the boat S = 3.4 knot = 6.3 \frac{km}{hr}

Time taken by bot to reach the island = 7 hr

We know that the distance is given by

Distance = Speed × Time

Put all the values in above equation we get

D = 6.3 × 7

D = 44.07 km

Therefore the distance between the docks & island is 44.07 km.
