Answer:
-6 a b + b + a
Step-by-step explanation:
Simplify the following:
-(a - b + a b) - a b - 4 a b + 2 b - 2 b + 3 a - a
Hint: | Group like terms in 3 a - 2 b - a b - (a b - b + a) - 4 a b + 2 b - a.
Grouping like terms, 3 a - 2 b - a b - (a b - b + a) - 4 a b + 2 b - a = -(a b - b + a) + (-a b - 4 a b) + (3 a - a) + (2 b - 2 b):
-(a b - b + a) + (-a b - 4 a b) + (3 a - a) + (2 b - 2 b)
Hint: | Combine like terms in -a b - 4 a b.
a b (-1) + a b (-4) = -5 a b:
-(a b - b + a) + -5 a b + (3 a - a) + (2 b - 2 b)
Hint: | Combine like terms in 3 a - a.
3 a - a = 2 a:
-(a b - b + a) - 5 a b + 2 a + (2 b - 2 b)
Hint: | Look for the difference of two identical terms.
2 b - 2 b = 0:
-(a b - b + a) - 5 a b + 2 a
Hint: | Distribute -1 over a b - b + a.
-(a b - b + a) = -a b + b - a:
-a b + b - a - 5 a b + 2 a
Hint: | Group like terms in -a b - 5 a b + b + 2 a - a.
Grouping like terms, -a b - 5 a b + b + 2 a - a = (-a b - 5 a b) + b + (-a + 2 a):
(-a b - 5 a b) + b + (-a + 2 a)
Hint: | Combine like terms in -a b - 5 a b.
a b (-1) + a b (-5) = -6 a b:
-6 a b + b + (2 a - a)
Hint: | Combine like terms in 2 a - a.
2 a - a = a:
Answer: -6 a b + b + a
Distribute first, then combine like terms:
15r - 10 +2(7r) + 5r + 3

A restaurant offered cooking classes on 24 of the 30 days in November. What decimal is equivalent to the fraction of days in November that classes were offered at the restaurant? Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value.
Answer:
80%
Step-by-step explanation:
Divide 24÷30 to obtain a decimal value. Then multiply the result by 100. This will move the decimal 2 places to the right. 0.8×100= 80%
If g(x) = 3x + 2.4, find g(3.1).
Answer:
11.7
Step-by-step explanation:
g(3.1)= 3(3.1)+ 2.4
= 9.3 + 2.4
= 11.7

For a school project, Brian counts the cars every weekday after to school to determine how many are silver. He records his findings
in this table. What is the experimental probability that the next car he sees will be silver?
A 1/2
B 1/3
C 1/4
D 1/5
A)
B)
C)
D
Answer:
The correct answer is A, 14%.
Step-by-step explanation:
All you have to do is take the 30% chance of you HAVING to stop at the first light and find the chance that you won't have to stop at the first light, which is 70%, or .7. Then you take the chance of having to stop at the second light which is 80%, and find the probability of NOT having to stop there, which is 20%, or .2. Then you multiply the probabilities of not having to stop, which equals .14.

276%
Answer:when reduced to the simplest form. As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 276/100 is also equal to 2 19/25 when expressed as a mixed number.
Step-by-step explanation:
Answer: 276/100 is also equal to 2 19/25 the expressed is a mixed number.

Step-by-step explanation:
Write a rule for the nth term of the arithmetic sequence described below.
A5 =
91 and a20 =
1
an=
A25=
Answer:
an = 115 + (n - 1) (-6)
a25 = - 29
Step-by-step explanation:
We use the definition for the nth term of an arithmetic sequence:
an = a1 + (n - 1) d
a5 = 91 = a1 + (5 - 1) d
91 = a1 + 4 d
a20 = 1 = a1 + (20 - 1) d = a1 + 19 d
1 = a1 + 19 d
now we subtract term by term one expression from the other
90 = 4 d - 19 d
90 = - 15 d
divide both sides by -15 to isolate d
d = 90 / (-15) = -6
Now we can calculate what a1 is using for example:
1 = a1 + 19 d
1 = a1 - 114
add 114 to both sides:
115 = a1
Then our general expression for the sequence is:
an = 115 + (n - 1) (-6)
We can now use it to calculate the value of a25:
a25 = 115 + (24) * (-6) = -29
Can somebody please help me with my math ?
Step-by-step explanation:
just plug in the numbers to the x values
if f(3) then ur equation would look like this f(3) = 4x - 5
then u solve it to get the answer.
3 = 4x - 5
+ 5 = 4x + 5
------------------ ---> add 5 on both sides
8 = 4x
now u just divide. 8 ÷ 4 = 2 so f(3) = 2

If I is || m, find the value of y.
A. 50
B. 5
C. 27
D. 10
Answer:
D. 10
Step-by-step explanation:
8x-14=5x+34
8x-5x=34+14
3x=48
x=48/3
x=16
8x-14+5y+16 = 180
8(16)-14+5y+16 = 180
128-14+5y+16=180
5y=180-128-16+14
5y=50
Y = 10
