ignore the numbers on top of the fruits but can someone help solve this?
Step-by-step explanation:
I don't know what the 3rd fruit is. let's call it an apple.
so,
1 apple + 3 cherries = 3 bananas
1 apple = 3 bananas - 3 cherries
1 banana + 2 cherries = 1 apple = 3 bananas - 3 cherries
5 cherries = 2 bananas
1 apple + 1 banana = (1 banana + 2 cherries) + 1 banana =
= 2 bananas + 2 cherries =
= 5 cherries + 2 cherries =
= 7 cherries
the numbers did not help, as they were wrong.
e.g. if you assume the apple = 5, a cherry = 1 and a banana = 2, you would get 8 = 6 on the first scale.
if you change the apple to a 3, that would make the first scale true (6 = 6), but the second scale wrong (4 = 3).
funny enough, the other answer got 7 nevertheless (but the wrong way - actually 2 mistakes balanced each other out).
it is 7 cherries, though !
the actual numbers would be e.g.
a cherry = 1
then
1 banana = 5/2 = 2.5
1 apple = 3×5/2 - 3 = 15/2 - 6/2 = 9/2 = 4.5
to get whole numbers, we could multiply all by 2 :
cherry = 2
banana = 5
apple = 9
and then the first balance :
9 + 3×2 = 3×5
9 + 6 = 15
15 = 15 correct
the second balance
5 + 2×2 = 9
9 = 9 correct.

Relation between sugar and flour
18 teaspoons of sugar per 3 cups of flourRate : 18/3 = 6 teaspoons of sugar per cup of flourTable
[tex]\left[\begin{array}{ccc}sugar(tsp)&flour(cups)\\12&2\\18&3\\36&6\\48&8\\54&9\end{array}\right][/tex]
Answer:
Step-by-step explanation:
Remark
The key to this question is the second entry. Numerically the sugar is divided by 6 to get the flour. Never mind the units. Just deal with the ratio itself.
Formula
Flour = Sugar / 6
Solution
Sugar = 12
Flour = 12/6 = 2
Flour = 18/6
Flour = 3
Flour = 6
6 = sugar/6 multiply by 6
6*6 = 6* sugar/6
36 = sugar
Sugar = 48
Flour = 48/6 = 8 cups of flower
Flour = 9
9 = sugar / 6
9*6 = sugar
Sugar = 54.

If , the ratio of the length of to the length of is .
Given the ratio of 5 : 3, the length of the rectangle is 45 units
How to determine the length?The ratio is given as:
Length : Width = 5 : 3
The perimeter is given as:
Perimeter = 144
The perimeter of a rectangle is:
Perimeter = 2 * (Length + Width)
So, we have:
2 * (Length + Width) = 144
Divide both sides by 2
Length + Width = 72
Recall that:
Length : Width = 5 : 3
Express as fraction
Length/Width = 5/3
Make Width the subject
Width = 3Length/5
Substitute Width = 3Length/5 in Length + Width = 72
Length + 3Length/5 = 72
Multiply through by 5
5Length + 3Length = 360
This gives
8Length = 360
Divide both sides by 8
Length = 45
Hence, the length of the rectangle is 45 units

➪ What is the quotient of 7 and the difference of a number and 8?
[tex]\diamond\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}\diamond[/tex]
➪ First, the word "quotient" indicates that we divide.
✳︎ Here, we are asked to divide 7 by the difference of a number and 8.
➪ The word "difference" indicates that we subtract.
✳︎ Here, we are asked to subtract a number minus 8.
Let the number be x.
Since the difference of x and 8 means we subtract x minus 8, this expression looks as follows:-
[tex]\texttt{x-8}[/tex]
◈ Now, we are also asked to find the quotient of 7 and the difference of a number and 8, which equals [tex]\bold{x-8}[/tex].
As I said earlier, the "quotient" means we divide, so we divide 7 by [tex]\bold{x-8}[/tex].
So we conclude that the expression is:-
7÷(x-8)

Line A is represented by the equation given below: x + y = 2 What is most likely the equation for line B, so that the set of equations has infinitely many solutions? (1 point) a 2x + 2y = 2 b 2x + 2y = 4 c 2x + y = 2 d x + y = 4
The set of the equations x + y = 2 and 2x + 2y = 4 have infinitely many solutions, option (b) is correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
equation of the line:
x + y = 2
a) 2x + 2y = 2 ⇒ x + y = 1
b) 2x + 2y = 4 ⇒ x + y = 2
c) 2x + y = 2 ⇒ 2x + y = 2
d) x + y = 4 ⇒ x + y = 4
The given equation and equation (b) 2x + 2y = 4 ⇒ x + y = 2 has the same coefficient of x and y as well as same constant it means the set of the equations have infinitely many solutions
Thus, the set of the equations x + y = 2 and 2x + 2y = 4 have infinitely many solutions option (b) is correct.

Answer:
2 hours and 44 min. or 2.7273 hours
Step-by-step explanation:
Ryan: 1 hole per 5 hours
Castel: 1 hole per 6 hours
x = time if working together then
x(1/5 + 1/6) = 1
x(6 + 5) = 30

A rectangular pyramid has a volume of 492 cubic yards. if the base has a length of 18 yards and a width of 4 yards, what is the height of the pyramid?
Answer:
h = 20.5 yards
Step-by-step explanation:
Volume of Rectangular Pyramid: lwh/3
492 = (18) * (4) (h) /3
Multiply 3 on both sides
1476 = (18) (4) (h)
1476 = 72h
Flip the equation.
72h = 1476
h = 41/2 or 20.5 yards
