Consider the following pair of equations:y = x + 4
y = –2x – 2

Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.

Answers

{ y = x + 4
y = - 2 x - 2

Subsititute y = - 2 x - 2 :

[ (- 2 x - 2 ) = x + 4 ]

( - 2 x - 2 ) = x + 4

Add 2 to both sides:

- 2 x - 2 + 2 = x + 4 + 2

- 2 x = x + 6

Which equation shows the quadratic formula used correctly to solve 7x2 = 9 + x for x?

Answers

For future reference, use a * to show the multiplication sign because in math x is a variable. 7*2 = 9 + x

Now multiply 7*2= 14

14 = 9 + x

Now subtract 9 from both sides to isolate the x

5 = x or x= 5

What is unitary method?

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Steps to Use Unitary Method

First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.

Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.

In rows of 4 there are 6 cards

and, he gave 7 cards to his friend.

So, he have

=6*4+ 7

=24+ 7

=31 cards

Hence, he have 31 cards.
