Answer:
Step-by-step explanation:
You just combine common variables.
8a^5 -4
3a^5 + a -2
11a^5 + a -6
The solution to the first is 11a^5+a-6.
The second:
3x^2 -2x + 1
-x^2 + 3x + 1
2x^2 + x + 2
2x^2+x+2
a train travelling at 60 km per hour completes the journey in 8 hour. How much faster would it have to travel to cover the same distance in 6 hour
Answer:
Total distance covered: 60x8 = 480
Speed needed to cover distance of 480 km in 6 hrs = 480/6 = 80 km/hr.
initial velocity : 60 km/hr.
Train needs to run faster with speed of 20km per hour to achieve same distance in 6 hrs.

At the grocery store, 6 pints of ice cream cost $8.94. How much would 35 pints of ice cream cost?
Answer:
52.15
Step-by-step explanation:
you need to find how much each pint cost by itself so...
8.94 divided by 6 is 1.49
then 1.49 x 35 = 52.15
and that is your answer
Answer:
$52.15
Step-by-step explanation:
i just dived 8.94 by 6 then multiplyed that answer by 35

Each wall measures about 65 feet tall and 80 feet wide. If Os Gemeos did a sketch on paper that was 8 inches tall for one wall, how wide would their sketch have to be to stay in proportion?
Given :
Wall measures about 65 feet tall and 80 feet wide.
To Find :
If Os Gemeos did a sketch on paper that was 8 inches tall for one wall, how wide would their sketch have to be to stay in proportion.
Solution :
Let, width of sketch is x.
Since, they are in proportion :
[tex]\dfrac{65}{10}=\dfrac{65+8}{x}\\\\x = \dfrac{10\times 73}{65}\\\\x = 11.23\ feet[/tex]
Therefore, width of sketch should be 11.23 feet.
Hence, this is the required solution.
At school on Friday the ratio of students who purchased a lunch to students who brought lunch was 4:3. Based on the ratio, how many brought lunch out of 490 students?
Answer:
210 students brought lunch
Step-by-step explanation:
At school on Friday the ratio of students who purchased a lunch to students who brought lunch was 4:3.
The ratio is
Students who purchased: Students who brought
= 4 : 3
The total proportion
= 4 + 3 = 7
The total number of students from the question is : 490
Hence, The number of students that brought lunch is calculated as:
3/7 × 490
= 210 students
Hence, 210 students brought lunch

complete the square for the expression, then factor the trinomial.
x^2-4x
please explain how to do it as well! :)
Answer:
Completing the square we get: [tex](x-2)^2-(2)^2[/tex]
and factoring the term we get: [tex]x(x-4)[/tex]
Step-by-step explanation:
We need to complete the square for the expression [tex]x^2-4x[/tex]
For completing the square the expression would be of form [tex]a^2+2ab+b^2=(a+b)^2[/tex]
For given expression we have to add (2)^2 and subtract to make it complete the square.
[tex]x^2-2(x)(2)+(2)^2-(2)^2\\(x-2)^2-(2)^2[/tex]
Now, we have to factor the polynomial using formula [tex](a)^2-(b)^2=(a-b)(a+b)[/tex]
So, [tex](x-2)^2-(2)^2\\=(x-2-2)(x-2+2)\\=(x-4)(x-0)\\=x(x-4)[/tex]
Completing the square we get: [tex](x-2)^2-(2)^2[/tex]
and factoring the term we get: [tex]x(x-4)[/tex]

Answer:
1. r = [tex]\sqrt[3]{\frac{3v}{4\pi } }[/tex]
divide v by 4/3, this is the same as multiplying v by 3/4 so you have 3v/4
then divide v by [tex]\pi[/tex] so you now have 3v/4[tex]\pi[/tex]
then get rid of the ^3 on r by putting the solution for r under a ∛
2. a) The equation might need to be written in terms of a because you may not know the value of a, but you know the value of everything else. If this is the case then you can simply rewrite the equation so that you can plug it all into a calculator and avoid certain possible errors.
b)
s = ut + 1/2 [tex]at^{2}[/tex]
subtract ut from both sides: s - ut = 1/2 [tex]at^{2}[/tex]
multiply both sides by 2: 2(s - ut)
divide both sides by [tex]t^{2}[/tex]: [tex]\frac{2(s - ut) }{t^{2} }[/tex] = a
answer: a = [tex]\frac{2(s - ut) }{t^{2} }[/tex]
I'm not entirely sure about b) for question 2 so you might wanna double check that with a friend
Solve for v.

V =
Answer:
v = 14/9 + 2y/9
Step-by-step explanation:
First add 2y to both sides. Then, divide both sides by 9. Now you have v isolated.

6(x + 5) = 6x + 11
5(x-2)=5x-7
-3(X - 4) = – 3x + 12 infinite solutions
4(x + 1) = 3x + 4 one solution
-2(x-3) = 2x - 6 one solution
6(x + 5) = 6x + 11 no solution

Please help me!!
Answer:
x=8
Step-by-step explanation:
bc (8-7) =1, 1 time 4 = 4 (we always do -/+ before multiplication)
and (10-8)=2, 2 time 2 = 4
since for both you get the same result therefore x=8

1. A student finds the slope of the line between (14, 1) and (18. 17). She writes 18 - 14
What mistake did she make?
A She should have added the values, not subtracted them.
B She used y-values where she should have used x-values,
C She mixed up the x- and y-values.
D She did not keep the order of the points the same in numerator and the denominator
A
B
c
The answer is D.
It should be 17 -1 / 18 -14

The graph shows a function
Answer:
E, D
Step-by-step explanation:
rate of change is the slope
slope is change in y over change in x
the slope of the graph is (3/2)
E has a slope of 1/2 which is less than 3/2
D has a slope of 1 which is also less than 3/2
8. A right triangle has an angle
measure of 52.49. What is the
value of x, the missing angle?
Answer:
