A student tries to solve the equation 2(x-7)+x-9. The student work is shown to the right describe the errors. Then solve the equation correctly
Answer: 3x - 23
Step-by-step explanation:
To solve the equation goes thus:
= 2(x-7)+x-9.
We have to open the bracket first
= 2x - 14 + x - 9
We then collect like terms
= 2x + x - 14 - 9
= 3x - 23
Therefore, the answer is 3x - 23

-0.1 = -10c who can answer this
Answer:
c = 0.01 | Hope I helped :')
Steps to answer:
1. Divide both sides by -10.
-0.1/-10=c
2. Simplify -0.1/-10 to 0.01.
0.01=c
3 Switch sides.
c=0.01
---------------
Checking your answer:
−0.1=−10c
1 Let c=0.01.
−0.1=−10×0.01
2 Simplify 10×0.01 to 0.1.
-0.1=-0.1

The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal
costs $78.86 before the discount, and they leave a 20% tip. If the tip applies to the cost of
the meal before the discount, what is the total cost of the meal? Round your intermediate
calculations and answer to the nearest cent.
Answer: $80.44
Step-by-step explanation:
First of all, find 20% of 78.86, which is approximately 15.77.
Then, add it to the cost of the meal.
Finally, discount 15% of 94.63, which is approximately $14.19, and then subtract it from $94.63, and there's your answer.

Complete question :
Scottie is standing next to a lighthouse on the edge of a cliff overlooking the ocean. The cliff is 30 meters above
sea level, and the lighthouse has a height of 15 meters. There is a man fishing in a boat directly below Scottie who
has hooked a fish that is 10 meters below the surface of the water.
a. Use positive and negative numbers to represent the locations in relation to sea level.
Scottie =
Top of the lighthouse =
The boat =
The fish =
meters
b. How far is Scottie from the fish?
Answer:
30 m ;
15 m ;
0 m;
40 m
Step-by-step explanation:
Scottie's position = standing on cliff
Height of cliff = 30 m above sea level
Height of lighthouse = 15 meters
Position of fish = 10m below sea level
Above sea level = positive, +
Below sea level = negative, -
Scottie's position = 30 m
Top of lighthouse = 15m
BOAT = surface of sea = 0m
Fish = - 10 m
Distance of Scottie from fish :
Scottie's position - Position of fish
30m - (-10)m
30m + 10m
= 40m

Step-by-step explanation:
Answer:
option 3
Step-by-step explanation:
Avery walked for 0.25 miles in 5 minutes. Then she stopped for 5 minutes to meet her friend.After that both of them walked 0.75 miles in 15 minutes.
Again this option is also correct.
Avery walked for 5 minutes at a pace of 20 minutes per mile. Then she stopped for 5 minutes to meet her friend.After that both of them walked for 15 minutes at a pace of 20 minutes per mile.
Because, Time taken to travel 1 mile is 20 minutes.
So, time taken to travel 0.25 miles = 20 * 0.25 = 5 minutes
Time taken to travel 0.75 miles = 20 * 0.75 = 15 minutes

What is the value of 6x+7y−5 when x = 2 and y = 3?
Answer:
28
Step-by-step explanation:
6(2) + 7(3) - 5
12 + 21 -5
It's a good idea to get into the habit of using parenthses
when substituting numbers in for variables.
Since x = 2 and y = 3, 6x + 7y - 5 is 6(2) + 7(3) - 5.
Simplifying from here, we get 12 + 21 - 5 or 33 - 5 which is 28.

One angle of a right triangle measures 34°. What is the measure of the other acute angle?
Answer:
Step-by-step explanation: one has to be 90 degrees, so 34 plus 90. The angles of a triangle always add up to 180 so, subtract the answer of 34 plus 90 from 80 and you should get the answer.

36 - 7p = -7 ( p - 5)
a) No Solution
b) One Solution
c) Infinite Solutions
Answer:
a) No Solution
Step-by-step explanation:
36 - 7p = -7(p - 5)
36 - 7p = -7p + 35
1 - 7p = -7p
1 = 0p
so a) No Solution
Answer:
[tex]36 - 7p = - 7(p - 5) \\ 36 - 7p = - 7p - 7 \times - 5 \\36 - 7p = - 7p + 35 \\ p \: terms \: togather \\ - 7p + 7p = 35 - 36 \\ 0p = - 1 \\ here \: we \: \: have \: 0p \\ so \: no \: solution \\ option(a) \\ thank \: you[/tex]

Answer:
quintic polynomial
Step-by-step explanation:
it depends on the degree and the degree is at 5 so its quintic quin means 5
Answer:
It is a Quintic Polynomial
Step-by-step explanation:
When classifying polynomials, there is usually a list that you should get that makes classifying easier.
I put the list down below.
In order to find if it is constant (0), linear (1), quadratic (2), cubic (3), quartic (4), or quintic (5), look at the exponent with the highest value (0 through 5), and it will give you the name. So in the equation, you have above, the highest exponent is 5. So this is a quintic.
In order to find the next part of the expression, monomial, binomial, trinomial, and polynomial, look at how many terms there are in the expression. There are 4 terms, so this a polynomial.

The slope of a line is -1/5, and the y-intercept is 5. What is the equation of the line written in general form?
x - 5y - 5 = 0
x - 5y - 25 = 0
x + 5y - 25 = 0
Answer:
x + 5y - 25 = 0
Step-by-step explanation:
Equation of line in slope intercept form is given as:
[tex]y = mx + b \\ \\ plug \: m = - \frac{1}{5} \: \: and \: \: b = 5 \\ \\ y = - \frac{1}{5} x + 5 \\ \\ 5y = - x + 25 \\ \\ x + 5y - 25 = 0[/tex]
Answer:
x + 5y - 25 = 0

Cisco is building a container for his plants. It is made out of a cube and two cylinders. He plans to paint each surface but cuts off the top of the two cylinders. He also wants to reinforce all the edges before putting it together. Which one is greater, the number of surfaces he has to paint, or the number of edges he has to reinforce
Answer:
Neither
Step-by-step explanation:
In the context, Cisco is building container for the plant which is made up of one cube and two numbers of cylinders. He wants to paint each of the surfaces of the figure but he cuts off the top of two cylinders. Thus neither of the surfaces are greater as Cisco has two cylinders or surfaces and a cube or a point that he cuts the two cylinders and now that he has four surfaces and a cube that has four points.
