Step-by-step explanation: can't be greater than 2.
five more than one-third of a number is -2. Find the number
Answer:
x = -21
Step-by-step explanation:
Words To Algebra:Words : Five more than one-third of a number = -2
Algebraic Equation: 5 + (1/3)x = -2
Isolate x:5 + (1/3)x = -2 [tex]\longmapsto\\[/tex] Subtract 5 from both sides
5 + (1/3)x - 5 = -2 - 5
(1/3)x = -7 [tex]\longmapsto\\[/tex] Multiply All sides by 3
(1/3)x * 3 = -7 * 3
x = -21
Check:5 + (1/3)-21 = -2
5 + -7 = -2
-2 = -2

Answer:
x = 12.633, -0.633
Step-by-step explanation:
x^2 -12x + 36 = 44
the underlined part is (x - 6) ^2
(x - 6)^2 = 44
(x - 6) = ± [tex]\sqrt{44}[/tex] (both positive and negative)
(x - 6 ) = + 6.6332495807108
x = 12.6332495807108 = 12.633
(x - 6 ) = - 6.6332495807108
x = - 6.6332495807108 + 6
= -0.6332495807108 = -0.633

An equation for the amount of money raised for charity is
seats sold, and y is the number of snacks sold.
Answer:
[tex]20s+4y=512[/tex]
Step-by-step explanation:
20 bucks a seat so multiply the # of seats by 20
4 bucks a snack so multiply the # of snacks by 4
set that all equal to 512

Answer:
0.5 < t < 3.5
Step-by-step explanation:
[Given] 64t-16t^2>28
[Rewrite] 64t - 16t² > 28
[Subtract 28 from both sides] 64t - 16t² - 28 > 0
[Reorder] - 16t² + 64t - 28 > 0

Theres a 4 at the bottom but i couldn't get it in
Answer:
See answer below.
Step-by-step explanation:
1. Start at point (0,0), This point is where the x-y-axis meet. Do not put a dot
there because this is your starting point.
2. Move to the left over to point -1 3/4 . This place is between -1 and -2, and
closer to -2 because the point is -1 .75. Remember this point is not on the
graph.
3. Now move up from that point to 4.5 and put a dot at that place. The point is in the Q II , to the left top.

Lisa likes to go to one movie per week. She usually spends $12 on her ticket and $10 on a drink and popcorn. How much money would she save in one year if we went on Tuesday’s when the price of a ticker was half off and she didn’t have any snacks?
Step-by-step explanation:
there are 52 weeks per year.
she would save on one visit
12/2 = $6 plus the $10 for snacks = $16
so, she would save in one year
52×16 = $832
The length of a rectangle is 4 units more than triple its width. If the perimeter is 64,
what is the length of the rectangle?
Answer: Length = 25, width = 7
Step-by-step explanation:
Let width be w, and length be 3w + 4.
Perimeter of a rectangle = 2l + 2w
64 = 2(3w + 4) + 2w
64 = 6w + 8 + 2w
64 = 8w + 8 [subtract 8 from both side]
56 = 8w [Divide 8 from both side]
w = 7
Plug w in l, where l = 3w + 4 = 21 + 4 = 25
