adding the equations together?
Answer:
the equation is not shown...
Step-by-step explanation:
but to solve for y you should use the first equation that is use the coefficient of x in the first equation to multiply all the terms in the second equation.
And use the coeffient of x in the second equation to multiply the the terms in the first equation.
It would have been better if the equation was shown for better explanation.
I want to know what is 600 minutes to days
Answer:
[tex]0.416667[/tex] of a day
Step-by-step explanation:
To get minutes to days you divide the minutes by the amount of minutes in a day which is 1440
[tex]\frac{600}{1440} \\0.416667[/tex]
Answer:
0.417 day
Step-by-step explanation:
First divide 600 by 60 the answer is 10 hours and then divide by 24 the answer would be 0.41666667 days
1) The perimeter of a rectangular classroom floor is 90 feet. The length of the floor is twice the
width. Which equation would NOT help us solve for the length and width of the classroom? Show your
your
work on
scratch paper. *
x + 2y = 90
x = 2y
2(2y) + 2y = 90
2x + 2y = 90
Answer: The equation would NOT help us solve for the length and width of the classroom is "[tex]x + 2y = 90[/tex]".
Step-by-step explanation:
Let y be the width of the rectangular classroom floor and x be the length of the rectangular classroom floor .
Given ,
The perimeter of a rectangular classroom floor is 90 feet.
The length of the floor is twice the width.
i.e. Length =2 (width)
i.e. x= 2y ..(i)
Also, perimeter = 2(length+width)
[tex]i.e. 2(x+y)=90\\\\\Rightarrow\ 2x+2y=90[/tex]
When we put value of x from (i), we get
[tex]2(2y) + 2y = 90[/tex]
Hence, the equation would NOT help us solve for the length and width of the classroom is "[tex]x + 2y = 90[/tex]".

A square patio has a perimeter of (32x+8) feet. What is the length of the patio? Thanks!
Answer:
The side length is 8x+2 ft
Step-by-step explanation:
The perimeter of a square is found by
P =4s where s is the side length
32x +8 = 4s
Divide each side by 4
32x/4 +8/4 = 4s/4
8x+2 = s
The side length is 8x+2 ft

Answer:
Step-by-step explanation:
Use Pythagorean theorem
let the missing side be x
5² +x² = 13²
25 + x² = 169
x² = 169 - 25
x² = 144
x =√144
x = 12 yards

Step-by-step explanation:
regular octagon rotates 360° about its center. How many times does the image of the octagon coincide with the preimage during the rotation?
Answer:
Step-by-step explanation:
because A regular octagon is a closed figure with sides of the same length and internal angles of the same size. so if it is rotated 360 degrees it should coincide with its preimage after every 45 degrees.
so 360/45= 8 times
Answer:
8 times
Step-by-step explanation:
An octagon has eight sides of equal length and eight angles of same measure. So, If it is rotated 360 degrees about its center. It would coincide with all of its 8 sides. So, it will coincide with it's pre-image 8 times.

Answer:
No solutions
Step-by-step explanation:
x + 2y and 2x + 4y are linear combinations of each other since 2 ( x + 2y ) = 2x + 4y.
However, since 2 ( x + 2y = 2 ) results in 2x + 4y = 4 and the second equation reads as 2x + 4y = -8, there is no solution to this system of equations since 4 does not equal -8.
Answer:
option B
Step-by-step explanation:
x+2y=2 ⇒x= 2- 2y2x+4y=-8 ⇒ 2(2-2y) +4y= -8 ⇒ 4-4y+4y= -8 ⇒ 4= -8 this is impossibleso no solutionsAnswer: option B

Answer:
side of square is 2-x
Step-by-step explanation:
Area of the square is side * side or side ², so the expression for the side has to be square root of area
A = 4 -4x + x²
It should be recognized that 4 -4x + x²is a special product ( 2-x)² because this is a perfect square trinomial
side of square is 2-x

find the coordinate of F' after a reflection of the triangle about the line y = -x. Write your answer in the form of (a,b).
F is (3,5)
Answer & Step-by-step explanation:
When you are doing the reflection, y = -x, then the coordinates will go as follow...
(x, y) → (-y, -x)
So, (3, 5) will become (-5, -3).
So, the coordinate of F' would be (-5, -3)

There is a bag filled with 4 blue and 5 red marbles. A marble is taken at random fròm the bag,the colour is noted and then is replaced. Another marble is taken at random. What is the probability of getting 2 blues
Hi there!
Answer:
1/6
Explanation:
The first probability of getting blue is 4 out of the total marbles so 4/9.
The second time there are only 3 blue marbles out of 8 now so 3/8.
So the answer is 4/9X3/8
which equals 12/72 or 1/6

Five out of six residents of Mayville have library cards. Which tool will best allow Darren to simulate this scenario and predict whether a randomly chosen resident has a library card?
Answer:
A number cube
Step-by-step explanation:
A coin a 5-sector spinner a number cube a bag of 11 marbles
A number cube is the best to simulate this scenario and predict whether a randomly chosen resident has a library card.
As Coin has only 2 outcomes "Head" and "Tail".
A 5-sector sector spinner has only 5 outcomes we need six outcomes.
A bag of 11 marbles has no differentiated with respect to colors etc.
Hence, A number cube is correct to chosen five out of six residents of Mayville have library cards.

Cynthia earns $680 in commissions and is paid $10.25 per hour. Javier earns $410 in commissions and is paid 12.50 per hour. What will you find if you solve for x in the equation 10.25x + 680 = 12.5x +410.
Answer:
x = 120
Step-by-step explanation:
10.25x + 680 = 12.5x +410.
Subtract 10.25x from each side
10.25x-10.25x + 680 = 12.5x-10.25x +410.
680 = 2.25x +410
Subtract 410 from each side
680-410 = 2.25x +410-410
270 = 2.25x
Divide each side by 2.25
270/2.25 =2.25x/2.25
120=x
is 11/7 and 77/63 equivalent?
is 3/5 and 45/75 equivalent?
is 1/8 and 10/80 equivalent?
is 2/9 and 18/81 equivalent?
Answer:
11/7 = (11 x 9)/(7 x 9) = 99/63 > 77/63
3/5 = (3 x 15)/(5 x 15) = 45/75
1/8 = (1 x 10)/(8 x 10) = 10/80
2/9 = (2 x 9)/(9 x 9) = 18/81
Hope this helps!

In science class, Liz learned that trees help make the oxygen that people breathe. One tree makes about 250 pounds of oxygen each year. Liz wonders how much oxygen the trees on her street make. When she gets home, she counts 32 trees on her street. How many tons of oxygen do they make in a year? tons
Answer: The answer is 8000 pounds, or 4 tons
Step-by-step explanation:
This is true because each tree makes about 250 pounds of oxygen. She counted 32 so.....
(32)(250)=8000
then convert 8000 pounds to tons and you get 4 tons
Each of forty-six pet owners was asked, "Does your pet eat more wet food or dry food?" Here are the results. 9 cat owners and 13 dog owners chose "Wet food". 10 cat owners and 14 dog owners chose "Dry food". Construct a two-way frequency table for the data.
Answer:
Cat owner Dog owner Total
Wet food 9 13 22
Dry food 10 14 24
Total 19 27 46
Step-by-step explanation:
It is given that 9 cat owners and 13 dog owners chose "Wet food". 10 cat owners and 14 dog owners chose "Dry food".
Cat owners-Wet food = 9
Dog owners-Wet food =13
Cat owners-Dry food = 10
Dog owners-Dry food =14
We need to construct a two-way frequency table for the data.
Take owners in the first row and type of food in first column and construct a two-way frequency as shown below:
Cat owner Dog owner Total
Wet food 9 13 22
Dry food 10 14 24
Total 19 27 46
