Answer:
x = -7
x = -5
x = -22
x = -8
Step-by-step explanation:
-14 = x - 7 (add 7 on both sides)
-7 = x
-12x = 60 (divide by -12 on both sides)
x = -5
x + 11 = -11 (subtract 11 on both sides)
x = -22
-x/4 = 2 (multiply both sides by 4)
-x = 8 (divide by negative)
x = -8

Douglas has a box with 49 paper clips.
Of the paper clips, 15 are yellow, 9 are
red, 6 are blue, 11 are orange and 8
are green. Douglas randomly picks 2
paper clips from the box.
If the first paper clip is red, what is the probability that the second paper clip is blue?
Answer:
6/48 is the likely possibility that he will pull out a blue one.
Step-by-step explanation:
The first thing you will look at is how many blue there is and in this case there is 6. All you have to do (if it didn't already) is add up all of the paperclips and put the blue total number to get your answer. So if there was 49 but he drew out one to make it 48. So the answer is 6/48

HELP ME ASAP PLEASE ?!?!Find the value of x.
Answer:
38 degree
Step-by-step explanation:
all the angles of a triangle are 180 . a supplementary angle is 105 degree... first subtract 180 - 105 (A), because it is a supplementary angle , so 75 degrees then do 180 - ( 67 + 75 ) that is 38 = x

When air is pumped into an automobile
tire, the pressure is inversely proportional to
the volume. If the pressure is 35 pounds
when the volume is 120 cubic inches, what
is the pressure when the volume is 140
cubic inches?
Answer:
The pressure P₂ = 30 pounds when volume is 140 cubic inches
Step-by-step explanation:
We are given
Pressure P₁ = 35 pounds
Volume V₁ = 120 cubic inches
Volume V₂ = 140 cubic inches
We need to find Pressure P₂
The formula used will be: [tex]V_1P_1=V_2P_2[/tex]
Putting values and finding P₂
[tex]V_1P_1=V_2P_2\\120\times 35=140\times P_2\\4200=140\times P_2\\P_2=\frac{4200}{140} \\P_2=30 \ pounds[/tex]
So, the pressure P₂ = 30 pounds when volume is 140 cubic inches
Solve -0.8(10 - x) = 36
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Linear equation.
Solving we get as,
-0.8(10-x)=36
=> -8 + 0.8x = 36
=> 0.8x = 36+8
=> 0.8x = 44
=> x = 44÷0.8
=> x = 55
x= 55.
The solution of the expression will be;
⇒ x = 55
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ -0.8 (10 - x) = 36
Now,
We can solve the expression as;
The expression is,
⇒ -0.8 (10 - x) = 36
⇒ - 0.8 × 10 + 0.8x = 36
⇒ - 8 + 0.8x = 36
⇒ 0.8x = 36 + 8
⇒ 0.8x = 44
⇒ x = 44 / 0.8
⇒ x = 55
Thus, The solution of the expression will be;
⇒ x = 55

Answer:
Andre scored 14 points.
Equation: x = 14
Step-by-step explanation:
Let the number of points Andre scored be x.
Diego's points = x-9
Noah's points = (x-9) × 2
= 2x-18
Now, you know the exact value of Noah's points which is 10.
2x-18 = 10
Isolate the 2x.
2x = 10+18
= 28
x = 28÷2
= 14
Answer:
noah = 10 pts.
diego = 5pts. half as many as noah.
diego is 9pts less than andre.
if diego scored 5 and is 9 less than andre. andre scored 5+9
Andre scored 14pts

A recipe calls for 1 1/2 cups of mayonnaise and 3/8 cups of pecans. How much mayonnaise should be used if 1 cup of pecans is used?
Answer:
4 cups of mayonnaise.
Step-by-step explanation:
The ratio of the amount of pecans comparing reality and the recipe is:
1 : 3/8
= 1/(3/8)
= 8/3
Hence, to find the amount of mayonnaise that should be added:
8/3 * 3/2
= 8/2
= 4 cups

10.6n - 45.92 = 18.8 solve for n
Answer:
Step-by-step explanation:
10.6n - 45.92 = 18.8 Add 45.92 to both sides
10.6n = 18.8 + 45.92 Combine like terms on the right
10.6n = 64.72 Divide by 10.6
n = 64.72 / 10.6
n = 6.11

Solve the equation 3/4x + 3 -2x = -1/4+1/2x+5
If necessary: Combine Terms
Apply Properties: Add, Subtract, Multiply, Divide
Answer:
x = -1
Step-by-step explanation:
3/4x + 3 -2x = -1/4 + 1/2x + 5
3/4x + 3 -2x = 19/4 + 1/2x
3x + 12 - 8x = 19 + 2x
-5x + 12 = 19 + 2x
-5x - 2x + 12 = 19
-7x = 19 - 12
-7x = 7
x = -1

The formula A = Pe^rt calculates the amount an investment earning a nominal rate of r compounded continuously is worth. Show that the amount of time it takes for the investment to double in value is given by the expression ln2/r.
Answer:
t = In2/ r
Step-by-step explanation:
Given the formula : A = Pe^rt
For investment to double ;
Final amount (A) = 2 * initial investment (p)
A = 2p
Hence,
2p = pe^rt
2 = e^rt
Take the In of both sides
In2 = rt
Divide both sides by r
In2 /r = rt /r
In2/ r = t
t = In2/ r ; Hence, the proof
The formula for obtaining the time taken when the amount is double the principal is ln2/r.
Given that;
A = Pe^rt
A = amount
P = principal
r = rate
t = time
Now we are told that;
A = 2P
Hence;
2P = Pe^rt
2 = e^rt
ln 2 = rt
t = ln2/r (QED)

Vanity Fair was having a blow out sale on shorts and t-shirts. Trevor bought 12 shorts and t-shirts. The shorts were on sale for $12 each and t-shirts were $6 each. Trevor spent $102. how many shorts and t-shirts did Trevor buy? Let x= shorts and y= t-shirts.
Answer:
shorts = 5and
t-shirts 7
Step-by-step explanation:
step one:
given
Let x= shorts and y= t-shirts
Trevor bought 12 shorts and t-shirts.
x+y=12----------1
sale for $12 each and
t-shirts were $6 each
12x+6y=102---------2
the sytems of equation is
x+y=12----------1
12x+6y=102---------2
Step two:
from 1, x=12-y
put x=12-y in 2
12(12-y)+6y=102---------2
144-12y+6y=102
144-6y=102
144-102=6y
42=6y
y=42/6
y=7
put y=7 in 1
x+7=12----------1
x=12-7
x=5

What is the value of c in the equation 3/4 x + 2= 5/4 x -6
Answer:
c isn't in the equation so I'm assuming you're solving for x
x=16
Step-by-step explanation:
3/4x+2=5/4x-6 start by subtracting 3/4x on both sides
2=2/4x-6 now add 6 to both sides
8=2/4x at this point you can simplify 2/4 to 1/2 just to make it easier to divide
8=1/2x divide 1/2 or 0.5 by 8

Cora and Cecilia each use chalk to make their own number patterns on the
sidewalk. They make each of their patterns 10 boxes long and line their patterns
up so they are next to each other.
Cora puts o in her first box and decides that she will add 3 every time to
get to the next number.
Cecilia puts o in her first box and decides that she will add 9 every time to
get the next number.
How many times greater is Cecilia's number in the 5th box than Cora's number in
the 5th box? What about the 8th? What predictions can you make about the
relationship between the values in the rest of the pattern?
Answer:
5th box has 45 for Cecilia and 15 for Cora
8th box has 72 for Cecilia and 24 for Cora
Cecilia's boxes numbers are 3 times of Cora's boxes numbers.
Step-by-step explanation:
This can be completed as follows .
0 1 2 3 4 5 6 7 8 9 10
Cora's boxes 0 3 6 9 12 15 18 21 24 27 30
Cecilia's boxes 0 9 18 27 36 45 54 63 72 81 90
The 5th box has 45 for Cecilia and 15 for Cora which means Cecilia's number is 3 times bigger than Cora's number in the 5th box.
The 8th box has 72 for Cecilia and 24 for Cora which means Cecilia's number is 3 times bigger than Cora's number in the 8th box.
As we see that the difference in numbers is of three times from the beginning to the end. Therefore we conclude that Cecilia's boxes numbers are 3 times of Cora's boxes numbers.
