Answer:
x = -12
y = 11
Step-by-step explanation:
i used substitution and let 'x' = 10 - 2y
3(10 - 2y) + 4y = 8
30 - 6y + 4y = 8
30 -2y = 8
-2y = -22
y = 11
x + 2(11) = 10
x + 22 = 10
x = -12
For camping mrjohn son needs 12 1-2 feet of rope to tie the logs that he has to cut for the campfire and 9 3-4 feet of the rope for the clothesline what is the total length of rope he needs for the camping trip
Answer:
Mr. John will need not less than [tex]22\frac{1}{4}[/tex] feet of rope for the camping trip
Step-by-step explanation:
To get the total length of rope Mr John needs for the camping trip, we can simply add up the length of rope he needs to tie the logs to the length of rope he needs for the clothesline.
Length of rope he needs to tie the logs = [tex]12\frac{1}{2}[/tex]
Length of rope he needs for the clothesline = [tex]9 \frac{3}{4}[/tex]
to sum this up, we, first of all, add up the whole numbers
12 + 9 = 21.
We then keep this aside then add up the fractions
[tex]\frac{1}{2} +\frac{3}{4} =\frac{2 +3}{4} = 5/4 = 1\frac{1}{4}[/tex]
We then add this to our whole numbers
[tex]21 + 1\frac{1}{4} =22 \frac{1}{4}[/tex]
Mr. John will need not less than [tex]22\frac{1}{4}[/tex] feet of rope for the camping trip

3f^4g^3 x 8fg^4 / (6f^2g^3)^2 how do you do this?
9514 1404 393
Answer:
2/3·fg
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
(a^b)/(a^c) = a^(b-c)
(ab)^c = (a^c)(b^c)
(a^b)^c) = a^(bc)
__
We assume your 'x' is a multiplication symbol, so you want to simplify ...
[tex]3f^4g^3 \times\dfrac{ 8fg^4}{ (6f^2g^3)^2}\\\\=\dfrac{3\cdot8f^{4+1}g^{3+4}}{6^2f^{2\cdot2}g^{3\cdot2}}=\dfrac{24}{36}f^{5-4}g^{7-6}\\\\=\boxed{\dfrac{2}{3}fg}[/tex]
for numbers 19 and 20 you have to solve for the missing angle.
Answer:19. 17 degrees
20. 49 degrees
Step-by-step explanation:
Because of the postulate 50+?=67
So ?=17
And 20.
94+?=143
So
?=49
(Edit)I though you only meant 19 and 20

can help me any one . If ₹640 is divided between Bishu and Arpana in the ratio of 5 : 3 , lets find how many each would get.
Answer:
a/q ratio 5:3 total money is divided in 8 parts so 1 part =rs 80 so b&a got 80×5=400 & 80×3 =240 resp
Answer:
first find the total = 5+3=8
now 5/8×640 =5×80 = 400 rupees
3/8×640 =3×80 = 240 rupees
so Bishu gets 400 rupees and Arpana gets 240 rupees.

Jaden scores 100 points in the first round of a game. He earned 20 points in each of the following rounds of the game. He ended the game with 400 points. Write and solve an equation that could be used to determine the number of extra rounds Jaden played.
Answer:
100 + 20 x n = 400
Step-by-step explanation:
If he ended the game with 400 points, and he scored 100 points in the first round, and 20 points every round after that, then we have to find out how many rounds he played using multiplication and addition. n represents the number of rounds he played, which is what we want to find out. What number do you have to multiply 20 by to get 300? the answer is 10. Therefore, n is 10.
Hope this helped :)

A rectangle has a perimeter of 36 inches and a width of 10 inches. What is the length of the rectangle?
Answer:
8
Step-by-step explanation:
A rectangular garden has a length that is 3 feet longer than its width. Let w represent the width of the garden in feet. The entire garden is surrounded by a 2-foot-wide cement walkway.
Answer:
Step-by-step explanation:
From the question, we're told that the length of the garden is 3 feet longer than its width. Mathematically, we would have
l = w + 3, where
l = length of the garden
w = width of the garden
Again we're told that this same garden has a walkway of about 2 foot wide. Mathematically we would have that as
W(w) = 2, where
W(w) = width of the garden.
That's all the parameters given in the question

Answer: $0.14 per ounce
Step-by-step explanation:
There are 28.5 ounces of shampoo in the shampoo bottle and the cost of the whole bottle is $3.99.
The cost per ounces will therefore be:
= Cost of bottle / Number of ounces
= 3.99 / 28.5
= $0.14 per ounce
(SAT Prep) Find the value of x.
X
125°
115°
#look pic for detailed info
180° - 125° = 55°
180° - 115° = 65°
180° - 55° - 65° = 60°
180° - 60° = 120°
180° - 120° = 60°
Answer:
x = 120°
Step-by-step explanation:
you can draw a perpendicular base betweeen the two parallel segments and form a pentagon, which has 540 degrees inside.
the two base angles will each be 90°, and we have known values for the other two.
as far as 'x', that angle is vertical to the top angle of the pentagon so we add up all the known values and solve for 'x':
90 + 90 + 125 + 115 + x = 540
180 + 240 + x = 540
x = 540 - (180 + 240)
x = 540 - 420
x = 120
