Answer:

a = -8

Step-by-step explanation:

4a - 7 = 5a + 1

<em>subtract 1 from both sides of the equation</em>

4a - 7 - 1 = 5a + 1 - 1

4a - 7 - 1 = 5a

4a - 8 = 5a

<em>subtract 4a from both sides of the equation</em>

4a - 4a - 8 = 5a - 4a

-8 = 5a - 4a

-8 = 1a

-8 = a

Somebody answer !!!!!
Rainbow [258]

Answer:

D)

Step-by-step explanation:

First we have to subtract 5 from both sides

\sqrt{x-6} +5=12\\\\\sqrt{x-6}+5-5=12-5\\\\\sqrt{x-6}=7

Now, square both sides

(\sqrt{x-6})^{2}=7^{2}

x - 6 = 49

Now, add 6 to both sides

x - 6 +6 = 49 + 6

x = 55

Please answer number 1 and 2.
zavuch27 [327]

1, a.) The two specific conjectures are in the first image.

1, b.) The two general conjectures are in the second image.

2, a.) Two specific conjectures for this pattern are:

  • The common difference between two consecutive terms is 3.
  • And the given difference is A.P.

2, b.) From our observation two general conjecture is that the given sequence is an arithmetic sequence and the common difference is 3.

For finding its nth term we can use the formula: a(n) = a + (n-1) x d.

2, c.) A formula for the given pattern is 5 + (n-1)3, where n is the number of the term.

Chandler wants to raise 200$ to buy a new gaming system. He already has 80$ and plans to save 40$ a week. How many weeks will it
SashulF [63]

Answer:

<h2>3 weeks</h2>

Step-by-step explanation:

Step one:

given data

expected amount =$200

cash already at hand=$80

savings per week=$40

let the number of weeks be x

Step two:

the linear function for the situation is the same as the equation of a straight line

y=mx+c------1

200=4x+80

solve for x

200-80=40x

120=40x

divide both sides  by 4

x=120/40

x= 3 weeks

<u>Chandler will save for 3 weeks</u>
