Answer:
-5/6a - 5/8
Step-by-step explanation:
In order to to simplify the linear expression you must combine like terms.
"like terms" are terms whose variables and exponents are the same. for example 2x and x are like terms. In this case, -2/3a and -1/6a are like terms as they have the same variable (a) and exponent (1). -2/3a - 1/6a = -4/6a - 1/6a = -5/6a
Next, we combine the constants 1/8 and -3/4. 1/8 - 3/4 is the same as 1/8 - 6/8 which is equal to -5/8. Therefore the final simplified linear expression is -5/6a -5/8.

take the -21 to the other side of the equation, when you do this it goes from a negative to a positive so we now have 63+21=12x

pls help...
Answer:
The identity sinA sin(A+2B) - sinB sin(B+2A) = (sinA)^2 - (sinB)^2 is proved below.
Step-by-step explanation:
sinA sin(A+2B) - sinB sin(B+2A) =
sinA ( sin(A) cos(2B) + sin(2B) cos(A) ) - sinB (sin(B)cos(2A) + sin(2A)cos(B) ) =
sinA( sinA [cos^2(B)- sin^2(B)] + 2 sin(B) cos(B) cosA ) - sinB( sinB(cos^2A-sin^2A)+2 sinA cosA cos(B) ) =
sin^2A(cos^2B-sin^2B) + 2 sinB cosB sin(A) cos(A) - sin^2B(cos^2A-sin^2A) - 2 sinA sinB cosA cosB =
sin^2A(cos^2B-sin^2B) - sin^2B(cos^2A-sin^2A) =
sin^2Acos^2B - sin^2Asin^2B - sin^2Bcos^2A + sin^2Bsin^2A =
sin^2Acos^2B - sin^2Bcos^2A =
(1 - cos^2A)(cos^2B) - (1 - cos^2B)(cos^2A) =
cos^2B - cos^2A cos^2B - cos^2A + cos^2B cos^2A =
cos^2B - cos^2A =
1 - sin^2B - (1 - sin^2A) =
sin^2 (A) - sin^2 (B)
Vera's piggy bank contained $10.90 in quarters, dimes, and nickels. There were six more than two times as
many nickels as quarters and four less than two times as many dimes as quarters.
Create an equation to represent the situation.
Answer:
[tex]6+2n+4-2d\cdot n = 1090[/tex]
Step-by-step explanation:
We have to convert everything to the same value. For example, 8$ would be 8 cents. And 1 Nickle would be 5 cents.
n = number of nickles
d = the number of dimes
q = number of quarters
1 nickle = 5 cents
1 dime = 10 cents
1 quarter = 25 cents
Step 1: Convert the total amount from dollars to cents.
There were $10.90 in total. Since there are 100 Cents in 1 Dollar, there would be 1090 cents in 10.90 dollars. (Tip you can easily find how many cents there are in dollars if you simply remove the decimal ".")
We are converting this because we need to have every value in the same term.
Step 2: Convert all of the amounts to cents.

Step-by-step explanation:
a variable x has a normal distribution with mean 54 and standard deviation 5. approximately what percentage of the observations will fall between 44 and 64?
For a normal distribution with mean 54 and standard deviation 5 95.4% of them fall between 44 and 64
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ \mu=mean.\sigma=standard\ deviation, x=raw\ score\\\\Given\ that\ mean(\mu)=54,standard \ deviation (\sigma)=5\\\\For\ x=44:\\\\z=\frac{44-54}{5}=-2\\\\For\ x=64:\\\\z=\frac{64-54}{5}=2[/tex]
Therefore., from the normal distribution table:
P(44<x<64) = P(-2< z < 2) = P(z < 2) - P(z < -2) = 0.9772 - 0.0228 = 0.9544
Hence, About 95.4% of them fall between 44 and 64.

A line passes through (–7, –5) and (–5, 4).
a. Write an equation for the line in point-slope form.
b. Rewrite the equation in standard form using integers.
Answer:
b. y + 5 = 9/2 ( x + 7 ) ; - 9 x + 2 y = 53
Step-by-step explanation:
The equation:
y - y 1 = ( y2 - y1 ) / ( x2- x1) * ( x - x1 )
y - ( - 5 ) = ( 4 + 5 ) / ( - 5 + 7 ) * ( x - ( - 7 ) )
y + 5 = 9/2 ( x + 7 )
y + 5 = 9/2 x + 63 /2 / * 2
2 y + 10 = 9 x + 63
- 9 x + 2 x = 53
Answer:

6. What are the first 4 multiples of 4? A. 2, 4, 8, and 12 C. 4, 8, 16, 20 B. 4, 8, 12, 16 D. 4, 8, 16, 24
please answer it correctly
Step-by-step explanation:
4.
GCF : greatest common factor, the biggest number all these numbers can be divided by without remainder.
so, 15, 30 and 45
let's find the basic factors of each
15/2 no
15/3 = 5
5/3 no
5/4 no
5/5 = 1
therefore, 3¹×5¹
30/2 = 15
15/3 = 5
5/3 no
5/4 no
5/5 = 1
therefore, 2¹×3¹×5¹
45/2 no
45/3 = 15
15/3 = 5
5/3 no
5/4 no
5/5 = 1
therefore, 3²×5¹
the largest combination of factors they all have is 3¹×5¹ = 15
so, the GCF = 15.
5.
since I don't know how many pupils there are this is a strange question.
or does this text mean there are 5 pupils ?
overall, there is something wrong with this question.
so, let's answer based on some assumptions :
the GCF (as in 4.) is 12
12×3 = 36
12×4 = 48
12×5 = 60
so, if there are 12 students, each one gets 5 notebooks, 4 ball pens and 3 correction tapes.
if there are 5 students, then each one gets 60/5 = 12 notebooks, 48/5 = 9 (3 remainder) ball pens and 36/5 = 7 (1 remainder) correction tapes.
6.
multiples of 4, that means 4*x with x = 1, 2, 3, 4, ...
so
4×1 = 4
4×2 = 8
4×3 = 12
4×4 = 16
therefore, B is the right answer.

$6
$9
$54
$150
Answer:
$6
Step-by-step explanation:
This is for one pencil to each student. Since each box is $3, and she has 25 students, you would figure out how many students are left out with one box, and since you only have one left, you only need one more box. That would mean two boxes, so $3x2= $6

Linear pair means a pair of adjacent angles formed when two lines intersect, and their sum is 180°
In the question it want one of the angles to be 16° more then the other, so the measures of the angles will be
180 - 16 = 164
164/2 = 82
Angle 1 = 82° Angle 2 = 82°+16 = 98°
Draw a straight angle (straight line), intersect it with another line such that the two angles that will be formed one of them will be of measure 98° and the other 82°

PS: DON'T WASTE MY POINTS PLEASE I WORK HARD FOR THIS POINTS IF YOU DON'T KNOW THE ANSWER CARE TO IGNORE:)
Answer:
C: 36 × 10^6 m²
Step-by-step explanation:
Given the side length of a square = 6 × 10³m,
To solve for the area of a square, use the following formula:
A = S² where:
S = side of the square
Substitute the given value for the side into the formula:
A = S²
A = (6 × 10³)²
A = 36000000 or 36 × 10^6 m²
NOTE:
6 × 10³ is also the same as 6 × 1000 = 6000,
(6 × 10³)² is essentially 6,000² = 36,000,000
Therefore, the correct answer is C) 36 × 10^6

Jace traveled 125 yards to the store. How many feet did he travel?
Answer:
375 feet
Step-by-step explanation:
1 yard = 3 feet
125 yards times 3 equals 375 feet
The unit measure for atmospheric pressure is kPa (Kilo-Pascals). At sea level the standard
atmospheric pressure is 101.3 kPa. For every 1000 feet increase in altitude, atmospheric
pressure decreases by 1.8 kPa. What is the atmospheric pressure at 50,000 feet?
The pressure change is an illustration of an arithmetic progression.
The atmospheric pressure at 50000 feet is 11.3 kPa
The given parameters are:
[tex]\mathbf{a = 101.3}[/tex] --- the first term
[tex]\mathbf{d = -1.8 per 1000}[/tex] -- common difference
At 50000 feet, the number of increment in altitude is
[tex]\mathbf{n = \frac{50000}{1000}}[/tex]
[tex]\mathbf{n = 50}[/tex]
So, the atmospheric pressure at 50000 feet is:
[tex]\mathbf{T_{50} = 101.3 - 1.8 \times 50}[/tex]
[tex]\mathbf{T_{50} = 101.3 - 90}[/tex]
[tex]\mathbf{T_{50} = 11.3}[/tex]
Hence, the atmospheric pressure at 50000 feet is 11.3 kPa
