Mrs. Williams combined 3 ½ cups of peat moss, 5 ¼ cups of compost , and 6 ¾ cups of fertilizer to make plant food for her roses. She evenly distributed the plant food among 4 rose bushes. How many cups of plant food were used for each rose bush?
Answer:
3 7/8 cups plants food
Step-by-step explanation:
peat moss = 3 ½ cups
compost = 5 ¼ cups
fertilizer = 6 ¾ cups
Total mixture = peat moss + compost + fertilizer
= 3 ½ cups + 5 ¼ cups + 6 ¾ cups
= 7/2 + 21/4 + 27/4
= 14+21+27/4
= 62/4
Total mixture = 62/4 cups
She evenly distributed the plant food among 4 rose bushes
Each rose bush uses = Total mixture / number of rose bushes
= 62/4 ÷ 4
= 62/4 × 1/4
= 62/16
= 3 14/16
= 3 7/8 cups plants food
Each rose bush uses = 3 7/8 cups of plants food

What is the percent Of decrease from 50 to 21
Please anwser accurate and I give brailiest
Answer:
29%
Step-by-step explanation:
To find the decrease from 50 to 21 you would subtract 50 - 21. You get 29. This is the same as 29/100. 29/100 is also 0.29 or 29%.
Hope it helps! (I'm so sorry if it's incorrect).

hey guys please answer if you know
Answer:
19
Step-by-step explanation:
note that
(a + b)² = a² + b² + 2ab , that is
a² + b² + 2ab = (a + b)² ← subtract 2ab from both sides
a² + b² = (a + b)² - 2ab
= 5² - 2(3)
= 25 - 6
= 19
Answer:
19
Step-by-step explanation:
since value of both a+b and a*b are given
formula for a^2 + b^2 is (a+b)^2-2*a*b
Substituting those value,
a^2+b^2=5^2-2*3
i.e. 25-6
=19
The scale of a map is 1 clear : 13 km. Find the actual distance corresponding to the map distance. The distance on the map is 4.5 cm The actual distance is ___ km
Answer: The actual distance is 58.5 km.
Step-by-step explanation:
Given: Scale of map = 1 cm : 13 km
The distance on the map is 4.5 cm.
To find : The actual distance corresponding to the map distance.
The actual distance corresponding to the map distance =
( distance on the map) x ([tex]\dfrac{13}{1}[/tex])
[tex]=4.5\times13\\\\=58.5\ km[/tex]
Therefore , the actual distance is 58.5 km.

Algebra - Two Questions
1. A system of linear equations is shown below as well as the first steps that Raffi is using to solve this system of linear equations by substitution. Choose the statement that best describes how Raffi is progressing toward a solution.
7x+y=4
3x−2y=3
Solution: Solve the first equation to obtain y=−7x+4. Substitute this into the second equation to get 3x−2⋅−7x+4=3.
2. Solve the following system by the substitution method.
2x−y=−4
−5x+3y=14
Answer:
The answer is below
Step-by-step explanation:
1) Below are the linear equations.
7x+y=4 (1)
3x−2y=3 (2)
The above linear equations are a system of equations. The substitution method is a technique for solving systems of linear equations.
Given that:
7x + y = 4
y = 4 - 7x
substitute y = 4 - 7x in equation 2, hence:
3x - 2(4 - 7x) = 3
3x - 8 + 14x = 3
17x = 3 + 8
17x = 11
x = 11/17
Put x = 11/17 in y = 4 - 7x
y = 4 - 7(11/17)
y = -9/17
2) 2x−y=−4 (1)
−5x+3y=14 (2)
From equation 1:
2x−y=−4
y = 2x + 4
Put y = 2x + 4 in equation 2:
-5x + 3(2x + 4) = 14
-5x + 6x + 12 = 14
x + 12 = 14
x = 2
Put x = 2 in y = 2x + 4:
y = 2(2) + 4
y = 8
Answer:
1. Raffi forgot to place the substituted expression in parentheses.
2. (2, 8)
Step-by-step explanation:
If you are taking the Solving Systems With Substitution Quick Check from Connexus here are all of the answers:
1. Solve one linear function in terms of one of its variables.
2. Substitute 3y from the second equation for x in the first equation.
3. Raffi forgot to place the substituted expression in parentheses.
4. Yes, because substituting the given ordered pair yields two true expressions.
5. (2, 8)

If it takes 9 3/4 yards of material to make curtains for 3 windows, how much material is needed?
Answer:
3.25 yards of materials will be needed for 1 window
Answer:
3 1/4 (Verified) ✅Step-by-step explanation:
This is a rate problem, so we will write rate as a proportion and write the desired rate with x for the unknown value we need to find.
9.75/3 = x/1
Cross-mulitply
3x = 9.75
Divide by 3
x = 3.25 or 3 1/4
Another great thing with proportions is that we can check them to ensure we got the correct answer. All we do is substitute our determined value in for x
9.75/3 = 3.25/1
9.75 = 9.75 ✅
The answer of x = 3 1/4 is correct.
