Answer:
J=63
Step-by-step explanation:
3b+27=2b+57
subtract 27 from both sides
3b=2b+30
subtract 2b from both sides
b=30
K+J=180
substitute the value of b into K
2(30)+57+J=180
117+J=180
subtract 117 from both sides
J=63

On the blueprint of a house, 39 millimeters represents 6 meters. The actual length of the living room is 4 meters. what is its length on the blueprint.?
=======================================================
Work Shown:
(39 mm)/(6 m) = (x mm)/(4 m)
39/6 = x/4
39*4 = 6*x
156 = 6x
6x = 156
x = 156/6
x = 26
The actual length of 4 meters corresponds to 26 mm on the blueprint.
Side note: I used the cross multiplication rule on the third line.
A number minus twice another number is 4. Three times the first number plus two times the second number is 12. Write a system of equations.
Step-by-step explanation:
x - 2y = 4 (1)
3x + 2y = 12 (2)

Jake, Anna, and Ling are each originally from different states: California, Texas, and New Jersey. One of the students is on Student Council, one is on the swim team, and one is in the math club. The following statements are true.
1. Ling is not involved with student government this year, and she has never been to Texas.
2. Anna rides the bus with the person from New Jersey.
3. Jake is not from California.
4. Jake likes to go to his friend's swim meets.
5. The person from California is Ling's neighbor. It is the person she goes to for math questions.
6. The person on Student Council was born in the same month as Anna.

It is often convenient to use a chart to record the logic of the problem. The attached shows a typical arrangement for logic problems of this kind. It lets each category relate to every other category.
We use an X to identify a combination that is ruled out by something in the problem statement. The numbers are used here to identify the statement that gives rise to the chart fill-in. (Note that statement 6 is redundant and is not necessary to solve the problem.)
A Dark green background color is used to identify a primary conclusion. (The first ones are that Ling is from NJ, and Anna is from CA, hence in the math club.) The faded green identifies a secondary conclusion that results after the primary conclusions are reached. (The green square with 5 is faded only to enhance its contrast. It is a primary conclusion based on statement 5.)
Once 2 of 3 squares are filled on a line or column of a 3×3 space, the remaining conclusion is obvious.

Let a: b: c = 7: 13:20 and a + b + c = 520 Find the values of a, b,c
Answer:
520
Step-by-step explanation:
Let the Ratio a:b:c be 7x:13x:20x Respectively.
So, Sum of Ratios is 520...
A+B+C = 520
7x+13x+20x=520
40x=520
x= 520/40
x= 13
Now, Put the value of x
A= 7x= 7×13= 91
B= 13x = 13×13= 169
C= 20x = 20×13= 260
Now Add the numbers if we get 520 it means all the three numbers are correct....
91+169+260= 520

(xy^2+x)dx + ( yx^2+y )dy =0
Answer:
(y^2+1)(x^2+1)=k
Step-by-step explanation:
It looks like it is possibly separatable.
Let's try.
Factor the x out on first term and factor the y out on second term:
x(y^2+1)dx+y(x^2+1)dy=0
Subtracting y(x^2+1)dy on both sides:
x(y^2+1)dx=-y(x^2+1)dy
Divide both sides by (y^2+1)(x^2+1):
x/(x^+2+1)dx=-y/(y^2+1)dy
Integrate both sides..
Use substitution u=x^2+1 and v=y^2+1...so du= 2x dx and dv=2y dy.
.5du/u=-.5dv/v
.5ln|u|=-.5ln|v|+c
Multiply both sides by 2:
ln|u|=-ln|v|+c
Plug in our substitutions :
ln|x^2+1|=-ln|y^2+1|+c
Absolute values unnecessary since insides are positive always.... also -ln(y^2+1)=ln(1/(y^2+1))
e^ on both sides:
x^2+1=k(1/y^2+1)
(y^2+1)(x^2+1)=k

C.3 3/10
D. 1 1/0
Answer:

Step-by-step explanation:
Cece spent 2 2/5 hours doing his math modules 1 1/5 hours doing his science. how munch more time did cece spend on doing his math module than on his science module? After analyzing, the answer is C.
Answer:
A 1 1/5
Step-by-step explanation:
For math 2 2 / 5 hours = (10 + 2 ) / 5 = 12/5
for science 1 1 / 5 hours = (5 + 1) / 5 = 6 / 5
so, math - science time is

Answer:
[tex]y=55\\x=108[/tex]
Step-by-step explanation:
We know that the total angle sum of the quadrilateral internal angles is 360° since we are working with a quadrilateral polygon.
So when finding the interior angles we set up the equation of
[tex]125+y=180\\72+x=180[/tex]
Subtract 180 by 125 and 72 to find y and x
[tex]y=55\\x=108[/tex]
In a punch recipe, each cup contains
0.4
cups of orange juice,
0.35
cups of pineapple juice, and
0.25
cups of citrus soda.
If Jess wants to make
128
cups of punch, how much citrus soda is needed?
Answer:
A. 4 cups pineapple juice+8 cups orange juice+12 cups seltzer=24 cups total
108/24=4.5, so you need 4.5*(recipe)=
18 cups pineapple juice, 36 cups orange juice, and 54 cups seltzer
B. each recipe makes 18 servings, so 4.5*(recipe) =4.5*18= 81 servings
C. 8 cups orange juice/12 cups seltzer=2 cups orange juice/3 cups seltzer=2/3 cups orange juice/1 cup seltzer
Step-by-step explanation:
please mark brainliest if someone else answers :)
If Jess wants to make 128 cups of punch then 32 cups of Citrus soda used.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
We have,
For 1 cup punch
0.4 cups of orange juice,
0.35 cups of pineapple juice, and
0.25 cups of citrus soda.
So, to make 128 cups the amount of each ingredient used
Orange juice: 128 x 0.4= 51.2
Pineapple juice: 128 x 0.35 = 44.8
Citrus soda: 128 x 0.25 = 32
