Answer:
Answer: y = (2k -pw)/p
Step-by-step explanation:
[tex]k = \frac{p}{2} (y + w)[/tex]
multiply 2 on both sides:
[tex]k \times 2 = 2 \times \frac{p}{2} (y + w) \\ \\ 2k = p(y + w)[/tex]
open the bracket:
[tex]2k = py + pw[/tex]
subtract pw from both sides:
[tex]2k - pw = (py + pw) - pw \\ 2k - pw = py[/tex]
divide p on both sides:
[tex] \frac{2k - pw}{p} = \frac{py}{p} \\ \\ y = \frac{2k - pw}{p} [/tex]
Answer:
[tex]\pi {y}^{ \alpha \: so \: y = k} [/tex]

If 8 years are subtracted from the present age of Jessica and 3 is added to the remaining number, then Olivia’s age can be found. If Olivia is two years older than Daniel who is 7 years old, then what is Jessica’s present age?
Answer:
Jessica is 14 years old.
Step-by-step explanation:
Let [tex]o[/tex] equal Olivia's age, let [tex]j[/tex] equal Jessica's age, and let [tex]d[/tex] equal Daniel's age. With this lets write out what we know:
[tex]d = 7[/tex]
[tex]o = d + 2 = 7 + 2 = 9[/tex]
[tex]o = j - 8 + 3 = j - 5[/tex]
[tex]9 = j - 5[/tex]
[tex]j = 9 + 5 = 14[/tex]
5 1/4-2 2/3
Solve and show equations
Answer:
5 1/4 - 2 2/3 = 31/12 = 2 7/12 = 2.5833333
Step-by-step explanation:
1. Conversion a mixed number 5 1/4 to a improper fraction: 5 1/4 = 5 1/4 = 5 · 4 + 1/4 = 20 + 1/4 = 21/4
To find new numerator:
a) Multiply the whole number 5 by the denominator 4. Whole number 5 equally 5 * 4/4 = 20/4
b) Add the answer from previous step 20 to the numerator 1. New numerator is 20 + 1 = 21
c) Write a previous answer (new numerator 21) over the denominator 4.
Five and one quarter is twenty-one quarters
Conversion a mixed number 2 2/3 to a improper fraction: 2 2/3 = 2 2/3 = 2 · 3 + 2/3= 6 + 2/3 = 8/3
To find new numerator:
a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/3 = 6/3
b) Add the answer from previous step 6 to the numerator 2. New numerator is 6 + 2 = 8
c) Write a previous answer (new numerator 8) over the denominator 3.
Two and two thirds is eight thirds
Subtract: 21/4 - 8/3 = 21 · 3/4 · 3 - 8 · 4/3 · 4 = 63/12- 32/12 = 63 - 32/12 = 31/12
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(4, 3) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 3 = 12. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - twenty-one quarters minus eight thirds = thirty-one twelfths.
Tìm x, y, z biết x(x+y+z )=-5; y(x+y+z )=9;7(x+y+z )=5
Answer:
Step-by-step explanation:
Có: 7(x+y+z)=5
=>x+y+z = 5/7 (1)
Lại có:
+) y(x+y+z)=9
=>y×5/7=9
y=9: 5/7
y=63/5 (2)
+) x(x+y+z)=-5
=>x×5/7=-5
x=-5:5/7
x=-7 (3)
Từ (1);(2) và (3) => -7+63/5+z =5/7
=>28/5+z=5/7
=>z=-171/35

I’m not very good at math and I need help
The answer would be 6.00%
Answer:
C
Step-by-step explanation:
First of all it's not that you aren't very good at math it's just that you don't YET understand the concepts,... Believe me when I say that I've been there!!!
To solve this problem you have to look at it as a solve for the unknown problem,... They say that The FORMULA (important) is the following:
S = Ar
This can be written:
S = A * r
They then say that
S = sales tax,
A = cost of the product
r = local sales-tax rate,...
THEN they start giving you information,... they say the COST of a television (cost of the product) is $400 dollars you can now enter this info in you formula,... A = cost of product,... so switch the letter with the assigned info,...
S = $400 * r
...and the sales tax is $24 dollars,... S stands for sales tax so switch the variable for the dollar amount,...
$24 = $400 * r
Now you just have to solve the equation (figure out $400 * what = $24) and easy way to do this is to simply divide $24 by $400,...
$24/$400=0.06,...
0.06 = 6.0% = 6.00%
Hope I helped, You can learn anything!,... Me out,... Chow,...!

Step-by-step explanation:
We can cross off a because it is impossible to have negative of a material.
Now lets get into the System of equations. First subtract both of them to have one common variable(we will find the second one later)
- P + N = 134
- P + 3.1N = 241.10
2.1N = 107.1
107.1/2.1 = 51
Now we know that n = 51
lets substitute,
P + 51 = 134
P = 83
Lets check
83 + 51 = 134

The average weight of the top 5 fish at a fishing tournament was 13.1 pounds. Some of the weights of the fish are shown in the table.
Answer:
The Heaviest fish weigh 15.3(lb)
Step-by-step explanation:
14.9 +12.5+11.6+11.2+x/5=13.1
50.2+x/5=13.1
65/5=13
65.5/5=13.1
65.5 -50.2 = 15.3

At chucky bee restaurant, the meal costs $55.25 and desserts cost $15.75 for 5 people. How much money does each person have to pay?
Answer:
$14.20
Step-by-step explanation:
First we add both the meal ($55.25) and the dessert ($15.75) to calculate the total cost which would be $77.00 Assuming the bill was evenly split among the five people, we would divide the total cost ($77.00) by all 5 people which gives us 14.20 so each person would have to pay $14.20.

Find the measure of unknown angle
Answer:
Step-by-step explanation:
z = 102 degree (opposite angles of a parallelogram are equal)
z + x + 34 = 180 degree 9sum of adjacent angles of a parallelogram is 180 degree)
102 + x + 34 = 180
x = 180 - 136
x = 44 degree
y + 102 + x = 180 degree (sum of interior angles of a triangle is 180 degree)
y + 102 + 44 = 180
y = 180 - 146
y = 34 degree
Answer:
x = 44°, y = 34°, z = 102°
Step-by-step explanation:
The opposite angles of a parallelogram are congruent , then
∠ z = 102°
Consecutive angles are supplementary , then
x + 34° + 102° = 180°
x + 136° = 180° ( subtract 136° from both sides )
x = 44°
∠ y = 34° ( alternate angle
