Answer:  x=-1

Step-by-step explanation:

−10+x+4−5=7x−5

−10+x+4+−5=7x+−5

(x)+(−10+4+−5)=7x−5(Combine Like Terms)

x+−11=7x−5

x−11=7x−5

Step 2: Subtract 7x from both sides.

x−11−7x=7x−5−7x

−6x−11=−5

Step 3: Add 11 to both sides.

−6x−11+11=−5+11

−6x=6

Step 4: Divide both sides by -6.

−6x

−6

Answer:

-10 + x + 4 - 5=7x - 5

Combine all like terms (numbers).

-11 + x = 7x - 5

Add 11 to both sides.

x = 7x + 6

Subtract 7x from both sides.

-6x=6

Divide both sides by -6.

x=-1

A party rental company has chairs and tables for rent. The total cost to rent 3 chairs and 2 tables is $18. The total cost to re
DerKrebs [107]
C= chair cost
t= table cost

Create two equations with the given information. Solve for one variable in equation one. Substitute that answer in equation two. Then you can solve for the needed information.
3c+2t=$18
5c+6t=$48

3c+2t=18
Subtract 2c from both sides
3c=18-2t
Divide both sides by 3
c=(18-2t)/3

Substitute the value for c in equation two:
5c+6t=$48
5((18-2t)/3)+6t=48
(90-10t)/3+6t=48
Multiply everything by 3 to eliminate fraction
(3)((90-10t)/3)+(3)(6t)=(3)(48)
90-10t+18t=144
90+8t=144
Subtract 90 from both sides
8t=54
Divide both sides by 8
t=$6.75 cost for table

Substitute the t value to solve for c:
3c+2t=18
3c+2(6.75)=18
3c+13.50=18
3c=4.50
c=$1.50 chair cost

Check:
5c+6t=$48
5(1.50)+6(6.75)=48
7.50+40.50=48
48=48

Hope this helps! :) If it does, please mark as brainliest.

<span>1. 5564÷91
I know that 9 * 6 = 56
5564 rounds to 5600
91 rounds to 9
Since 56/9 = 6, then 5600/90 is the same as 560/9 = 60
The estimate is 60

2. </span><span>5391÷25
5391 sounds to 5400
25 is 1/4 of 100.
That means when you divide by 25, you can divide by 100 and multiply by 4.
5400/100 = 54
54 * 4 = 216
Estimate: 216

3. </span><span>explain how to estimate 498÷12
48/12 = 4
498 is little more than 480, so 498/12 is little more than 40
