The sum of two consecutive even integers is 106. what are the integers

jolli1 [7]

Let the consecutive even integers be x and (x+2).

x + (x + 2) = 106

2x + 2 = 106

2x = 104

x = 52

Thus the two integers are 52 and 54.

What is the ordered pair for point b on the graph (-1,4) (4,-1) (5,1) (1,5)

IRINA_888 [86]

Option C: (5,1) is the ordered pair for point B

Explanation:

The graph is plotted with unit scale 1 units for both x and y axis.

We need to determine the ordered pair for point B.

<u>Ordered pair:</u>

Since, the graph is plotted with unit scale 1, the point B is 5 units away from the point (0,0)

Thus, the x - coordinate for point B is 5.

Also, the point B is 1 unit away from the point (0,0)

Thus, the y - coordinate is 1

The coordinates of point B is (5,1)

Thus, the ordered pair for point B is (5,1)

Hence, Option C is the correct answer.

The price p of a gallon of gas goes up to $0.05 cents on Friday. On Saturday the price goes down $0.03. Write a expression with

m_a_m_a [10]

Answer:

The expression with three terms to show the price of a gallon of gas on Saturday is ⇒ $p+0.05-0.03$

Step-by-step explanation:

Given:

Price of a gallon of gas in dollars = $p$

On Friday, the price goes up by = $0.05

On Saturday, the price goes down by = $0.03

To write an expression with three terms to show the price of a gallon of gas on Saturday.

Solution:

Initial price of a gallon given in dollars was = $p$

On Friday the price increased by $0.05.

So, the price on Friday in dollars can be given as = $p+0.05$

On Saturday, the price decreased by $0.03

So, the price on Saturday in dollars can be given as = $p+0.05-0.03$

Thus, the expression with three terms to show the price of a gallon of gas on Saturday is ⇒ $p+0.05-0.03$
