Answer:
B= 16
b/4 - -1 =5 is the same as b/4 + 1 = 5
b/4 + 1 = 5
- 1 both sides
b/4 = 4
x 4 both sides
b=16
16/4 - -1 =5
4 + 1 = 5
- - Means add
+ + Means add
- + Means take away or minus
Hope this helps!

Assume each bottle of juice is the same price. If c represents the total cost in dollars and cents of the juice for any number, j, of bottles of juice
Answer:
c = ?
j = 13 bottles
c × j = $9.23
c = $9.23 ÷ j
= $9.23 ÷ 13
= $0.71 / 71 cents
Answer:
$0.71
Step-by-step explanation:
If c x j = $9.23 and j is 13, then c is $9.23/13
$9.23/13 = $0.71
=$0.71

Answer:
x= 21/4
Step-by-step explanation:
1- Convert the expressions
5 ( x - 3 3/4 ) = 7 1/2
2- Remove the parentheses
5 ( x - 15/4 ) = 15/2
3- Move the constant to the right
5x - 75/4 = 15/2
4- Calculate the sum
5x = 15/2 + 75/4
5- Divide both sides
5x = 15/2 + 75/4
7, 11, 2, 18. What number continues the pattern?
Answer:
-7
Step-by-step explanation:
Seems like the pattern is adding and then subtracting the next square number up:
7 + 4 = 11
11 - 9 = 2
2 + 16 = 18
so 18 - 25 = -7 is the next number

Answer:
-3
Step-by-step explanation:
Lets convert 4 2/3 to an improper fraction
-(4 * 3/3 + 2/3)/1 5/9
Combine 4 and 3/3
-(4 * 3/3 + 2/3)/1 5/9
Combine numerator over denom
-4 * 3 + 2/3/1 5/9
Simplify numerator
-12 + 2/3/1 5/9
Add 12 and 2
-14/3/1 5/9
Now we convert 1 5/9 to an improper.
-14/3/(9/9) + (5/9)
Combine
-14/3/(9 + 5)/9
Add 9 and 5
-14/3/(14/9)
Multiply yhe numerator by the reciprocal of the denom
-14/3 * 9/14
14(-1)/3 * 9/14
-1/3 * 9
Cancel the common factor of 3
-1/3 * (3(3))
-1 * 3 = -3
Solve the following equation
Answer:
n = -13
Step-by-step explanation:
38 = -2n + 12
Subtracting 12 from both sides:
==> 38 - 12 = -2n + 12 - 12
==> 26 = -2n
multiplying both sides by (-1):
==> -26 = 2n
dividing both sides by 2:
==> -13 = n
Answer:
Step-by-step explanation:
38 = -2n + 12
26 = -2n
n = 26 : (-2)
n = -13
-----------------
check
38 = -2 * (-13) + 12
38 = 26 + 12
38 = 38
the answer is good

What is a Simplified Expression?A simplified expression is an expression that is evaluated to its simplest form, that is, it cannot be simplified further.
Given:
(6x - 2) - (-x + 5)
Open the bracket by multiplying each of the terms in (-x + 5) by the negative sign (-):
6x - 2 + x - 5
Combine like terms
7x - 7
Thus, the expression, (6x - 2) - (-x + 5), is simplified as 7x - 7. The student's error was wrong calculation in the final steps where he subtracted 2 from 5.

The relationship between altitude and the boiling point of a liquid is linear. At an altitude of 8400ft, the liquid boils at 202.92°F. At an altitude of 4400ft, the liquid
boils at 207.72°F. Write an equation giving the boiling point b of the liquid, in degrees Fahrenheit, in terms of altitude a, in feet. What is the boiling point of the
liquid at 2200 ft?
Answer:(a) getting the equation:
We'll assume that the altitude is represented by the x-axis and that the boiling point is represented by the y-axis.
Therefore, we have two given points:
(8400 , 200.4) and (4200 , 206.7)
Since the relation is linear, therefore, the graph forms of straight line with the general equation:
y = mx + c where m is the slope and c is the y-intercept.
First, we will calculate the slope:
m = (y2-y1) / (x2-x1) = (206.7 - 200.4) / (4200 - 8400) = -0.0015
Therefore, the equation of the line now is:
y = -0.0015x + c
Then, we will need to calculate the y-intercept. In order to do so, we will use any give point and substitute in the previously obtained equation as follows:
y = -0.0015x + c
206.7 = -0.0015(4200) + c
c = 213
Based on the above calculations, the equation of the line is:
y = -0.0015x + 213
(b) getting the boiling point at altitude = 2100 ft:
Now, in order to calculate the boiling point at altitude 2100, we will substitute in the equation of the line as follows:
y = -0.0015(2100) + 213 = 209.85 degrees Fahrenheit

chanda wants to put 150 square metres of garden at her backyard. This is the maximum area of garden she can have. She wants to have a rectangular area of garden with length one metre less than 3 times with the width. Find the length and width to the nearest tenth of a metre
Answer:
length: 20.7 mwidth: 7.2 mStep-by-step explanation:
Let x represent the width of the garden. Then its length is 3x-1 and its area is ...
A = LW . . . . . . . . . . . . area of a rectangle is length times width
A = (3x -1)(x) = 150
3x^2 -x = 150
x^2 -1/3x +1/36 = 50 +1/36 . . . . divide by 3 and complete the square
x -1/6 = √(50+1/36) . . . . . . . . . take the square root
x = (1 +√1801)/6 ≈ 7.2397 . . . width of Chanda's garden
The length will be ...
3x -1 = 3(1 +√1801)/6 -1 = (1 +√1801)/2 -1 = (-1 +√1801)/2 ≈ 20.7191
To the nearest tenth meter, the garden is 20.7 m long and 7.2 m wide.

What is the factorization of the polynomial below ? 16x2 -9
Answer:
(4x + 3)(4x - 3)
Step-by-step explanation:
I am going to assume by 16x2 -9 you mean 16x² - 9
The factorization means the factors are "broken" up. If you multiply them together, we will reach 16x² - 9 again.
First, we can look at factors of 9. This gives us 1, 3, and 9. We will use 3. Since the nine is negative, one will be + 3 and one will be - 3 since a negative times a positive is a negative.
( + 3)( - 3)
Last we can factor the 16x² portion. I know that 4 times 4 is 16, and 4x times 4x is 16x².
(4x + 3)(4x - 3)

Here mark the angles
m<FHG=75m<FGH=55m<GHI=59°m<GIH=63°By using angle sum property
m<IGH=180-122=58So
m<FGH < m<IGH <m<GHI <m<GIH <m <FHGSo
FH<IH<GI<GH<FGAnswer:
IH < GI < GH < FH < FG
Step-by-step explanation:
Find missing angles
Sum of interior angles of a triangle = 180°
⇒ ∠GFH = 180 - 55 - 75 = 50°
⇒ ∠IGH = 180 - 59 - 63 = 58°
Side lengths in relation to interior angles
The longest side of a triangle is opposite the largest interior angle, and the shortest side is opposite the smallest angle.
Therefore, angles/sides in order of least to greatest:
ΔIGH
∠IGH = 58 → its opposite side is IH
∠GHI = 59 → its opposite side is GI
∠G|H = 63 → its opposite side is GH
Therefore, IH < GI < GH
ΔFGH
∠GFH = 50 → its opposite side is GH
∠FGH = 55 → its opposite side is FH
∠FHG = 75 → its opposite side is FG
Therefore, GH < FH < FG
Combining: IH < GI < GH < FH < FG
