x=2
x=-4
Step-by-step explanation:
[tex] |x + 1| = 3[/tex]
[tex]x + 1 = 3 \\ x + 1 = - 3[/tex]
therefore
[tex]x = 2 \\ x = - 4[/tex]
What is the value of the expression below when y=6y=6?
6y-1
6y−1
Answer:
The value of expression 6y-1 will be 35 when y=6.
Step-by-step explanation:
Given expression is:
6y - 1
We have to find the value of expression when y=6
Putting y=6 in the given expression
6*6 - 1
36 - 1
35
The value of the expression will be 35 for y=6
Hence,
The value of expression 6y-1 will be 35 when y=6.

complete the steps to solve for x
4/5x -1.4x = 11
Note: Your equation is a little unclear. But, I am assuming the equation
4/5x -1/4x = 11
The solution would anyways clear your concept.
Answer:
The value of x = 20
Step-by-step explanation:
Given the expression
4/5x -1/4x = 11
Multiply by LCM = 20
4/5x × 20 - 1/4x × 20 = 11 × 20
16x - 5x = 220
11x = 220
Divide both sides by 11
11x/11 = 220/11
x = 20
Thus, the value of x = 20
which values for x and y satisfy the following equations
y=x-1 and 2x + y=8

4/3C, when C=6
show your work here
4 divided by 3C
If C equals 6, then the equation now looks like 4 divided by 3(6).
3 x 6 = 18.
4 divided by 18 is .22 repeating.
This may be wrong. Check with another answer.
Answer: 2/9
Work: So, you are going to get the equation after plugging in the number 4/3(6), after simplifying even more, you get 4/18. Then you simplify again and divide both sides (Numerator and denominator) and you get 2/9.
I hope this helps, and Happy Holidays! :)
The length of a rectangle plus its width is 32
cm. The area is 112 square cm. What are the
length and width of the rectangle?
Separate the answers with a comma.
Answer:
l = 28 cm and b = 4 cm
Step-by-step explanation:
Let the length be l and the breadth be b.
ATQ,
l+b = 32
l=32-b ....(1)
Area of rectangle, A = 112 cm²
We need to find the length and width of the rectangle
The formula for the area of a rectangle is given by :
lb = 112 ...(2)
From equation (1) and (2).
(32-b)b = 112
From above equation, b = 4 cm
Put the value of b in equation (1)
l=32-4
= 28 cm
Hence, the length and width of the rectangle is 28 cm and 4 cm.

Find the percent of decrease from 32 to 8
Answer:
75%
Step-by-step explanation:
Find the percentage of 8 out of 32
8/32 times 100 = 800/32 = 25%
8 is 25% of 32, so the percentage to fall from 32 to 8 is 75%because
100% - 25% = 75%

The midpoint of AB is M (-1, -5). If the coordinates of A are (3, -8), what are the coordinates of B?
Answer:
coordinates of point B are (-5, -2)
Step-by-step explanation:
Recall that the midpoint of the segment that joins (x1, y1) with (x2, y2) is given by:
( (x1 + x2)/2 , (y1+y2)/2)
Therefore, given the information about the midpoint being (-1, -5) and A being (3, -8) we get:
For the x value (x2) of point B:
-1 = (3 + x2) / 2 then -2 = 3 + x2 and finally solving for x2; x2 = -2 - 3 = -5
For the y value (y2) of point B:
- 5 = (-8 + y2) / 2 then -10 = - 8 + y2 and finally y2 = -10 + 8 = - 2
Then point B has the coordinates: (-5, -2)

Answer:
a = 3.46 , c = 9.9
Step-by-step explanation:
These are the following identities:
[tex]sinx=\frac{perpendicular}{hypotenuse} \\\\cosx=\frac{base}{hypotenuse}\\\\tanx=\frac{perpendicular}{base}\\[/tex]
Easier way to learn this is
Some people have curly brown hair till painted black
Sinx = per/hyp cosx = base/hyp tanx = per/base
So if use the angle 60° we can see that the opposite side(perpendicular) to the angle is 6 and the base side is a so we need the identity which uses the opposite side(perpendicular side) and the base side and not the hypotenuse so that is tan x so,
[tex]tan\ 60=\frac{6}{a} \\\\1.732=\frac{6}{a}\\\\1.732a=6\\a=\frac{6}{1.732}\\\\a=3.46\\[/tex]
So a = 3.46
Now to calculate c:
If we take the angle 45° and see the opposite side(perpendicular side) is 7 and the hypotenuse is c so need the identity which uses the opposite side(perpendicular side) and the hypotenuse and not the base, which is sin x so,
[tex]sin 45=\frac{7}{c}\\\\0.707=\frac{7}{c}\\\\0.707c=7\\\\c=\frac{7}{0.707}\\\\c =9.9\\[/tex]
so c = 9.9

A recipe calls for 1 part coconut to 4 parts sugar. How much sugar will you need if you use 20 grams of coconut?
Answer:
80
Step-by-step explanation:
1:4 = 20:80
We are multiplying 20 by 1 to get 20 grams of coconuts. Also, we are multiplying 4 by 20 to get 80 grams of sugar. Therefore, you will need 80 grams of sugar if you use 20 grams of coconut. By the way, I suggest you review ratios if you are having difficulties with it.
38) It is recommended that there be at least 13.8 square feet of ground space in a
garden for every newly planted shrub. A garden is 32.2' by 18'. Find the
maximum number of shrubs the garden
can accommodate.
a) 3 shrubs
b) 13 shrubs
c) 42 shrubs
d) 193 shrubs
Answer:
c) 42 shrubs
Step-by-step explanation:
Calculation to Find the maximum number of shrubs the garden can accommodate
First step is to calculate the Area of Garden
Area of Garden = (32.2 ft)*(18 ft)
Area of Garden= 579.6ft²
Now let calculate the maximum number of shrubs the garden can accommodate using this formula
Maximum number shrubs=(579.6 ft²)/(13.8 ft² per shrub)
Maximum number shrubs = 42 shrubs
Therefore the maximum number of shrubs the garden can accommodate will be 42 shrubs

Suppose that the grades of Business Mathematics and Statistic module is modeled well
by a normal probability distribution with mean (212) and standard deviation (122). Let
X be the random variable representing this distribution. Find two symmetric values "a"
and "b" such that Probability [ a
Answer:
a = -2.57 and b = 2.57
Step-by-step explanation:
Explanation:
Given mean of the Population = 212
Standard deviation of the Population = 122
Let X be the random variable of the Normal distribution
[tex]Z = \frac{x-mean}{S.D}[/tex]
Given P( a ≤ z ≤b) = 0.99
put a=-b
P( -b ≤ z ≤b) = 0.99
⇒ |A( b) - A( -b)| =0.99
⇒ | A( b) + A( b)| =0.99
⇒ 2 |A (b)| = 0.99
⇒ | A(b)| = 0.495
From normal table find value in areas
b = 2.57 ( see in normal table)
Given a =-b
a = - 2.57

The table shows the amounts of onions and tomatoes in different-sized batches of a salsa recipe.
Elena notices that if she takes the number in the tomatoes column and divides it by the corresponding number in the onions column, she always gets the same result.
What is the meaning of the number that Elena has calculated?
onions (ounces) tomatoes (ounces)
2 16
4 32
6 48
The meaning of the number that Elena has calculated is; the proportion of tomatoes to onions used in making the salsa recipe
How to calculate the unit proportion rate?The unit rate is defined as a ratio that represents the rate of something per unit. For example we can say that A car is driving at a speed of 50 kilometers per hour. Thus, the unit rate is 50 kilometers per hour.
Now, we are given a table showing the amounts of onions and tomatoes in different-sized batches of a salsa recipe.
For 2 ounces of onions used, 16 tomatoes are used
For 4 ounces of onions used, 32 tomatoes are used
For 6 ounces of onions used, 48 tomatoes are used
Now, we are told that she takes the number in the tomatoes column and divides it by the corresponding number in the onions column. This would represent the ratio of tomatoes to onions that is used in making a salsa recipe.
