Create an equation for the problem here. Don't put any spaces.
How many weeks will it take?
Answer:
Take the number of weeks as x
12x = 544 - 100
x =444/12
x = 37

To make butter cream use butter and icing sugar in the ratio 1 : 2 . If I use 50g butter, how much icing sugar should I use?
Answer:
100 g
Step-by-step explanation:
You would multiply the butter by 2.
g(1)=0
g(n)=g(n-1)+n
g(2)=????
If g(1) = 0 and g(n) = g(n-1) + n, then g(2) = 2
The given relationship is:
g(1) = 0
g(n) = g(n-1) + n
g(2) = ?
Since g(1) is already known
g(2) = g(1) + 2
Note that g(1) = 0
Substitute g(1) = 0 into g(2) = g(1) + 2
g(2) = 0 + 2
g(2) = 2
Therefore, if g(1) = 0 and g(n) = g(n-1) + n, then g(2) = 2

The length of the rectangle is 5 cm longer than twice its width. If the perimeter of the rectangle is 88 cm what is the width? pls help
l = 5 + 2w.
P = 88 cm.
P = 2 ( l + w )
88 cm = 2 ( (5 + 2w) + w)
88 cm = 2 (5 + 3w)
88 cm cm = 10 + 6w
88 cm cm - 10 = 6w
78 cm = 6w
78 cm : 6 = w
13 cm = w
The width is 13 cm.
How many squares would have to be shaded so that 2/9 of the shape is shaded?
Answer:
4.
Step-by-step explanation:
There are 18 squares, if you want to shade 2/9 you have to make the denominator, which is 9 into 18, so you multiply by 2, you will do the same thing to the numerator, 2x2=4 9x2=18.
Brainiest would be appreciated.
There are 4 squares that would have to be shaded so that 2/9 of the shape is shaded.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
We have to determine the number of squares that would have to be shaded so that 2/9 of the shape is shaded
According to the given figure,
There are 3 rows and 6 columns of squares
So the number of squares would be 3 × 6 = 18
There are 18 squares, therefore if you want to shade 2/9, you must first divide the denominator, which is 9 into 18, by 2, and then multiply by 2.
If 2/9 of the shape is shaded: 18 × 2/9 ⇒ 36/9 = 4
Hence, there are 4 squares that would have to be shaded so that 2/9 of the shape is shaded.

17. y=1 - 2x x=9
(Help this is due today)
Answer: y= -17
Step-by-step explanation:
y= 1 - 2x
so when x=9,
y= 1 - 2(9)=1 - 18= -17
Answer:
y=-17
Step-by-step explanation:
y= 1-2x
since x=9, we substitute the x for 9
y= 1-2(9)
then we multiply 2 with 9
y= 1-18
y=-17

Smart ppl please help meee
Answer:
The reason why the area is 2a+3a+4a is because ax2=2a ax3=3a and ax4=4a know we know each segment so after that you add the segments to get the are equation which is 2a+3a+4a.
The reason why the area is also (2+3+4)a is because you just factored the orginial equation and if you use the distributive property they equal the same.

For the expression 6 - y + 3, determine the coefficient for the variable
term.
-1
0
3
6
Answer:
Step-by-step explanation:
The coefficient of a variable is always the number before the variable, if there is no number before a variable the coefficient is always 1.
In this case, since the subtraction sign is before the variable, you will need to make the variable positive by making the coefficient of variable y, -1.
In short terms, your answer is -1. :)

Step-by-step explanation:
Rashid owned n sheep. Eifion had exactly 4 times as many sheep as Rashid. Rashid buys 17 extra sheep. Eifion sells 8 of his sheep. Eifion still has more sheep than Rashid. Form an inequality, in terms of . Solve the inequality to find the least value of
4n - 8 > n + 17
n > 8.33
This means n is greater than 8.33.
We can have 9, 10, 11, 12, 13, ,,, and so on.
The least value is 9.
The least value of the number of sheep is 9.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal =
Greater than and equal=
We have,
Rashid:
Number of sheep owned = n
Bought 17 sheep = n + 17
Eifion:
Number of sheep owned = 4n
Sells 8 sheep = 4n - 8
Eifion still has more sheep than Rashid.
This means,
4n - 8 > n + 17 ______(1)
Solving for n in (1).
4n - 8 > n + 17
Subtract n on both sides.
4n - 8 - n > n + 17 - n
3n - 8 > 17
Add 8 on both sides.
3n - 8 + 8 > 17 + 8
3n > 25
Divide 3 on both sides,
n > 25/3
n > 8.33
This means n is greater than 8.33.
We can have 9, 10, 11, 12, 13, ,,, and so on.
The least value is 9.
Thus,
The least value of the number of sheep is 9.

The number of yodelers is twice the number of xylophones, how do I write this in a equation ?
Answer:
X=(Y*2) // Y=(X/2)
Step-by-step explanation:
Xylophones = "X"
Yodelers = "Y"
First Equation: X=(Y*2) essentially just explains that the xylophones is equal to the yodelers times 2
Second Equation: Basically the same thing, but rather than multiplying the yodelers by two, it divides the xylophones in half.
