Answer: The number is 23
Step-by-step explanation:
Let x be the [number]
Rephrase the expression
a number increased by 11 is equal to twice the number decrease by 12
x+11=2x-12
Add 12 on both sides
x+11+12=2x-12+12
x+23=2x
Subtract x on both sides
x+23-x=2x-x
x=23

Answer:
12 yd and 2 ft
Step-by-step explanation:
The company can not produce enough reels.
Step-by-step explanation:
Reels produced per day = 800
Production cut = 1/5
Let, the daily production be 1.
therefore,
New per day production = 1-
New per day production = 4/5
Therefore,
4/5 of 800 = New no. of reels produced per day
= New no. of reels
640 = New no. of reels
New. no of reels produced per day = 640
Reels produced in 30 days = 640*30 = 19200
The company can not produce enough reels.

Part A
From the two buildings she rents, the building costing $643, 225 price is greater than the other that costs <span>$635, 895
Part B
Round to the nearest ten thousand:
</span><span>$635, 895 ~ $640, 000
this is because 5,895 rounds to 6,000, and then this rounds to 10,000
</span><span>$643, 225 ~ $640, 000
</span>this is because <span>43, 225 rounds to 40,000 the nearest ten thousand</span>
<span>x^2+15=8x
</span><span>x^2-8x=-15
x^2 - 2 (x)(4) =-15
adding 16 on both sides
</span>x^2 - 2 (x)(4) +16=-15+16
x^2 - 2 (x)(4) + 4^2= 1
(x-4)^2=1
taking square root on bothsides x-4 = +-1
so x-4=1 or x-4=-1
x-5 or x=3
