Answer:
5x + 15y =20 = - 3x +25y =75
= 8 minutes
Step-by-step explanation:
5x + 15y =20 multiply all by 3 to get 15x
15x +45y=60
- 3x +25y =75 multiply all by -5 to get 15x
15x -125y = -375
rewrite ans together
15x +45y=60
15x -125y = -375
-80y = -315
y = -315/ - 80
y = 3.9375 = y= 4 substitute to find x
5x + 15(4 )=20
5x +60 = 20
5x=-40
x= -40/5
x=-8
15x +45(4)=60
15x +180 =60
15x =-120
x=-8

A grocery store receives a crate with contents that weigh 180 pounds. The contents consist of six 10-pound bags of potatoes and an unknown number of 5-pound bags of potatoes. Choose an equation that represents the number of bags of potatoes in the crate.
A: 6(10) + 180 = 5x
B: 10 + 6 + 5x = 180
C: 180 = 5 + 60x
D: 6(10) + 5x = 180
Answers
Answer:
6(10)+5x=180
Step-by-step explanation:
This is because there are 6 10-pound bags that we know of, so it would be 6(10).
Then, there are an unknown number of 5-pound bags, in which the variable would be x, so it would be 5x.
Lastly, the content weighs 180 pounds, so that's what the equation would be equal to.

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
(2x+7) x = 30
you can distribute to make this easier
2x^2 + 7x = 30
you can plug this into quadratic formula by setting the equation =0, so:
2x^2 +7x -30 = 0
where 2x^2 = a
7x = b
and -30 = c
you can plug this into your calculator and get an answer of
X = 2.5
Here is a flower made up of yellow hexagons, red trapezoids, and green triangles. How many copies of this flower pattern could you build if you had 6 yellow hexagons, 2 red trapezoids, and 9 green triangles?
Answers
Answer:
Step-by-step explanation:Answer:
Part a) You could build 5 copies of the flower pattern
Part b) You would have 40 red trapezoids left over
Step-by-step explanation:
The complete question in the attached figure
Part a)
Let
x -----> the number of yellow hexagons
y ----> the number of red trapezoids
z ----> the number of green triangles
we know that
The flower pattern has the following ratios
Find out how many copies of this flower pattern could you build if you had 30 yellow hexagons,50 red trapezoids, and 60 green triangles
1) For x=30
Divide 30 by 6 (remember that in one pattern there are 6 yellow hexagons)
Verify the quantity of y needed and the quantity of z needed
Find the value of y
10 < 50 ----> is ok
Find the value of z
45<60 --->is ok
2) For y=50
Divide 50 by 2 (remember that in one pattern there are 2 red trapezoids)
Verify the quantity of x needed and the quantity of z needed
Find the value of x
150 > 30 ----> is not ok
3) For z=60
Divide 60 by 9 (remember that in one pattern there are 9 green triangles)
60/9=6.7 copies
Round down
6 copies -----> 6(9)=54 green triangles
Verify the quantity of x needed and the quantity of y needed
Find the value of x
36> 30 --->is not ok
therefore
You could build 5 copies of the flower pattern
Part b)
we know that
x:y:z=6:2:9
If you build 5 copies
1) You would use 5*6=30 yellow hexagons and you would have 0 hexagons left over
2) You would use 5*2=10 red trapezoids and you would have (50-10=40) trapezoids left over
3) You would use 5*9=45 green triangles and you would have (60-45=15) triangles left over
therefore
You would have 40 red trapezoids left over
At the same time, Sam and Fred who are 168 miles apart begin moving toward each other. Find the number of hours before they meet if Sam runs 12 mph and Fred runs 9 mph.
Answers
Answer: 8 hours
Step-by-step explanation:
Let x be the time before they meet ( in hours)
Speed of Sam = 12 mph
Sped of Fred = 9 mph
Distance = Speed × time
Distance covered by Sam in x hours = 12x
Distance covered by Fred in x hours = 9x
(Distance) (rate1) (time1) (rate2) (time2)
Total distance between them: 168 = 12 x + 9 x
\(\Rightarrow\ 168= 21x\\\\\Rightarrow\ x=\dfrac{168}{21}=8\)
Hence, the number of hours before they meet if Sam runs 12 mph and Fred runs 9 mph. = 8

\(105+3x=180 \\ \\ 3x=75 \\ \\ x=25\)
Answer:
The answer is 25 degrees
Step-by-step explanation:
If you subtract 180 - 105 then you get 75.
Then you divide it by 3.
One circle is 360 degrees thus half of it is 180.
If you know one angle is 105 degrees then subtract it from 180.
If the number is 3x then you have to divide it by 3 to get x alone.

1/7 is half of
Answers
Answer:
1/14
Explanation:
To get half of anything, you simply divide it by 2. Therefore, half of 1/7 is the same as 1/7 divided by 2, which means that this is the fraction math problem we are solving:
1/7 ÷2
To divide a fraction by a whole number, you keep the numerator and multiply the denominator by the whole number like this:
1/ 7×2 = 1/14
That is all there is to it! Below is the the answer to "half of 1/7?" in its simplest form:

They are saying that they have this conference room mapped out on a poster board kinda like a road map. But if you put something that big on a board it wont fit. So they had to make it small enough to fit it. When they say that 1/2 on the board is equal to 12 feet in the real room, They are tell you the scale you have to go by. So then they give you 3 1/2 inches on the board. You would see how many 1/2 inches there are in 3 1/2, which is 7, and multiply 7 by 12. The answer would be 84 feet. So they are say that 3 1/2 inches on the poster board, represents 84 feet in the real room.
