What is the solution to the linear equation: 2/5+p=4/5+3/5p
Answer:
p = 1
Step-by-step explanation:
2/5 + p = 4/5 + 3/5p
2/5 + p = 3p/5
2/5 + p = (4 +3p)/5
2 + 5p = 4 + 3p
5p = 4 + 3p - 2
5p = 3p + 2
5p - 3p = 2
2p = 2
p = 1
Please mark me the brainliest!?!
Answer: C. P = 1
Step-by-step explanation: Plug in 1 to the both p variables on both sides, and you will get the same answer for each equation.

The slope-intercept form is mx + b = y.
According to the form, 4 = m which is also the slope.
Help asap please I’ll give brainlyest A set of equations is given below:
Equation C: y = 4x + 8
Equation D: y = 4x + 2
Which of the following best describes the solution to the given set of equations?
O No solution
One solution
OTwo solutions
O Infinitely many solutions
Answer:
No solutions.
Step-by-step explanation:
Easy way to spot is to take the 4x term to the LHS.
[tex]y-4x = 8\\y-4x = 2[/tex]
You're required to find a quantity that is at the same time equal to both 8 and 2, which is obviously impossible.
There are two ways to figure this equation out.
Answer: O No solution
Way One - Graphing
We can graph the two equations. Points of intersection represent a solution to the set.
-> See attached.
Since there are no points of intersection, the answer is "O No solution"
Way Two - Analyzing the Equations
We can see that both of these equations have a slope of 4. We then can set them both equal to the y-intercept to see if they will have solutions.
y = 4x + 8
-> y - 4x = 8
y = 4x + 2
-> y - 4x = 2
Because 8 ≠ 2, but y - 4x = y - 4x, the answer is "O No solution"
Choose all the fractions that are equivalent to1/7. (Click all that apply.)
4/28
7/49
7/70
2/8
2/14
5/35
Answer:
2/14, 4/28, 5/35, 7/70 or just 2/14
Step-by-step explanation:
Multiply both the numerator and denominator of 1/7 by 2, to get 2/14, or 2:14
And multiply the numerator and denominator of 1/7 by 3, to get 3/21, or 3:21. So 2:14 and 3:21 are two ratios that are equal to 1:7.

In the above figure, m∠A = 30° and m∠B = (2x + 10)°. If angles A and B are complementary angles, what are the value of x and the measure of angle B?
A.
x = 55, m∠B = 60°
B.
x = 25, m∠B = 60°
C.
x = 70, m∠B = 150°
D.
x = 25, m∠B = 50°
Answer:
Step-by-step explanation:
option B
Complementary angles add up to 90°
m∠A + m∠B = 90
30 + 2x + 10 = 90
2x + 40 = 90
To find the value of x, we have to isolate x. To isolate x, first we have subtract 40 from both sides.
2x = 90 -40
2x = 50
Now, divide both sides by 2
x = 50/2
x = 25°
∠B = 2x + 10
= 2*25 + 10
= 50 + 10
∠B = 60°
a store is charged $5.50 each for calculators and a delivery of $25 for the order. If stores sells the calculators for $8 each, how many calculators must be sold to produce a profit of at least $80?
Answer:
a store is charged $5.50 each for calculators and a delivery of $25 for the order. If stores sells the calculators for $8 each, how many calculators must be sold to produce a profit of at least $80?
Step-by-step explanation:
Cost minus the charge which is 8 dollars minus 5.50 is the difference in which you divide 80 by it. 8-5.50= 2.5. 80 divided by 25 = 32. Hope this is the answer you're looking for.

Ofb) = (x - 1)^2(x + 1)(x - 3)
Answer: A) f(x) = (x − 2)^2(x + 1)(x − 3)
Step-by-step explanation: The graph shows the zeros to be -1, +2 (multiplicity 2), and +3.
When b is a zero, (x-b) is a factor. Then the factors of the function shown are ...
f(x) = (x -(-1))·(x -2)·(x -2)·(x -3)
f(x) = (x -2)^2(x +1)(x -3)

They will bowl for one hour and dinner will take 1 hour and 15 minutes. Travel time is 20 minutes to the bowling alley, 45 minutes ta the restaurant, and ten minutes to the theater. At what time should they plan to leave Carlo's house?
Answer:
They should leave Carlo's house by 4:20 PM
Step-by-step explanation:
The movie starts at 8:10 pm, they want to arrive 20 minutes before the movie starts
20 minutes before 8:10 pm = 7:50 pm.
Hence, they should arrive by 7:50 pm
Duration of their activities before the movie is calculated as:
They will bowl for one hour and dinner will take 1 hour and 15 minutes. Travel time is 20 minutes to the bowling alley, 45 minutes ta the restaurant, and ten minutes to the theater.
: 1 hour + 1 hour 15 minutes + 20 minutes + 45 minutes + 10 minutes
= 2 hour 15 minutes + 75 minutes
= 2 hour 15 minutes +1 hour 15 minutes
= 3 hours 30 minutes in total.
The time they are meant to leave is calculated as:
7:50 pm - 3 hours 30 minutes
= 4:20pm

A)Show this information on the graph.
B) describe the relationship between the age and the value of the cars.
A car of the same type and make is 3 1/2 years old
C) estimate the value of the car
Answer:
a) you need to plot a cross on the graph (with the pencil) in the right place:
(x-axis: 4, y-axis: 2600)
b) the older the car is, the lower its value. there is a negative correlation between the cars age and its value.
c) you need to draw a line of best fit on the graph. where the line is at 3 1/2 years, that is its estimated value. (my guess is around £3000)

Gabriel put $6000 in a 5-year CD paying 4% interest compounded monthly. After 2 years, he withdrew all his money, and as an early withdrawal penalty, he paid back all the interest he made during the first year. How much money was Gabriel left with?
Using compound interest, it is found that Gabriel was left with $6,255.
What is compound interest?The balance, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which the parameters are given as follows:
P is the principal, which is the value of deposit/loan/....r is the interest rate, as a decimal value.n is the number of times that interest is compounded per year, annually n = 1, semi-annually n = 2, quarterly n = 4, monthly n = 12.In the context of this problem, the values of these parameters are as follows:
P = 6000, t = 2, r = 0.04, n = 12.
The balance after two years is:
[tex]A(2) = 6000\left(1 + \frac{0.04}{12}\right)^{24}[/tex]
A(2) = 6499.
The balance after one year is:
[tex]A(1) = 6000\left(1 + \frac{0.04}{12}\right)^{12}[/tex]
A(2) = 6244.
The interest paid on the first year was:
A(1) - P = 6244 - 6000 = 244.
Hence the amount that he was left with is:
6499 - 244 = $6,255.
