Answer:

5x + 2x.....combine like terms..... = 7x

5x + 2x....subbing in 1                               7x - 1....subbing in 1

5(1) + 2(1) = 5 + 2 = 7                               7(1) - 1 = 7 - 1 = 6

5x + 2x...subbing in 2                                 7x - 1...subbing in 2

5(2) + 2(2) = 10 + 4 = 14                            7(2) - 1 = 14 - 1 = 13

5x + 2x...subbing in 3                                 7x - 1...subbing in 3

5(3) + 2(3) = 15 + 6 = 21                            7(3) - 1 = 21 - 1 = 20

5x + 2x...subbing in 4                                 7x - 1....subbing in 4

5(4) + 2(4) = 20 + 8 = 28                            7(4) - 1 = 28 - 1 = 27

5x + 2x...subbing in 5                                 7x - 1...subbing in 5

5(5) + 2(5) = 25 + 10 = 35                          7(5) - 1 = 35 - 1 = 34

5x + 2x result values are 1 more then 7x - 1 result values

there are no values that will make the 2 expressions equal....

because 5x + 2x = 7x......and the other one is 7x - 1......so the 7x - 1 values will always be 1 number less...because ur subtracting one

Answer:

You would add 5x+2x=

7x which is one term.

Substitute 5 for X which will make 5(5)= 35 +2(5)= 10= 45

do the same for 7(5)= 35-1 = 34

so no, no value can make the two expressions equal.

If point E is the midpoint of and point D is the midpoint of , which expression represents the value of s
iogann1982 [59]

The length of ED is half the length of AB.

<h3>What is the length?</h3>
  • Distance is measured by length.
  • Length is a quantity with the dimension distance in the International System of Quantities.
  • Most measurement systems use a base unit for length from which all other units are derived.
  • The meter is the foundation unit of length in the International System of Units.

Reasons:

The given parameters are;

In ΔABC, point E is the midpoint of AC

The midpoint of BC is the point D

Segment ED = s

Segment CE = p

Segment EA = r

Segment CD = q

Segment DB = t

Segment ED = s

Segment AB = u

Required:

The expression that represents the value of s.

Solution:

CE = 0.5 × AC Definition of midpoint

CD = 0.5 × CB Definition of midpoint

Therefore, we have;

\frac{CE}{AC} =\frac{CD}{CB} =0.5

Therefore, given that ∠C ≅ ∠C, by the reflexive property, we have;

ΔABC is similar to ΔCDE by Side-Angle-Side similarity

Which gives;

\frac{CE}{AC} = \frac{CD}{CB}  = \frac{ED}{AB} =0.5=\frac{1}{2}

ED = s and AB = u which gives;

\frac{ED}{AB}=\frac{s}{u}  =0.5=\frac{1}{2}

\frac{s}{u} =\frac{1}{2}

Which gives:

s=\frac{1}{2} *u

The expression that represents the value of s is; s = one-half u

Therefore, the length of ED is half the length of AB.

If point E is the midpoint of segment AC and point D is the midpoint of segment BC, which expression represents the value of s? triangle CAB, point E is on segment AC between points A and C and point D is on segment BC between points B and C, creating segment ED, CE equals p, EA equals r, CD equals q, DB equals t, ED equals s, and AB equals u s equals p over q s = one half s equals q over p s = 2u

The tickets for a concert are sold in two different categories. The cost of a ticket in the standing area in the front of the st
mihalych1998 [28]

Answer:

The expression for the total amount of tickets sales can be give in dollars as :

⇒ 130y+73,500

Step-by-step explanation:

Given:

Cost of a ticket in standing arena = $210

Cost of a ticket for a seat = $130

Total people that can accommodate in standing arena = 350

Total number of seats in the concert = y

To  write the expression for the total amount of tickets sales if the concert is sold out.

Solution:

The concert is sold out. This means 350 tickets for standing arena and y tickets for seats are sol out.

Using unitary method to find the total cost.

If a ticket in front stage arena costs =  $210

<em>Then, 350 such tickets will cost</em> = 350\times \$ 210=\$ 73,500

If a ticket for a seat costs = $130

<em>Then, y such tickets will cost </em>= y\times \$ 130=\$ 130y

Total amount of ticket sales can be given as:

\textrm{Total cost of seat tickets in dollars sold + Total cost of front stage tickets in dollars sold}

⇒ 130y+73,500
