Drew had $48 in his savings account. Each week he added $8 to his account. Stacie had $87 in her account. Each week she took $5 out. After how many weeks will they have the same amount of money in their savings accounts?
What would be the equation to figure this out?
Answer:
after 3 weeks
Step-by-step explanation:
y=8x
y=-5x
y=8*3=24+48=72
y=-5*3=-15
87-15 is 72
after 3 weeks
It takes 3 weeks to be the amount of Drew and Stacie same in the bank account.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
Let's say it takes x week to be same the amount of Drew and Stacie.
Amount after x week of
Drew ⇒ 48 + 8x
Stacie ⇒ 87 - 5x
For to be it same,
48 + 8x = 87 - 5x
8x + 5x = 87 - 48
13x = 39
x = 3
Hence " It takes 3 weeks to be the amount of Drew and Stacie same in the bank account".

The expression shows the side length, in feet, of the bulletin board is √n feet option (A) is correct.
What is a square?It is defined as a two-dimensional geometry that has four sides and four vertices. The sides of the square are equal in length. It is a regular quadrilateral.
It is given that:
Kal is decorating the outside edge of a square bulletin board.
The figure is a square and the area of the square is n square feet where n is any real number.
As we know,
The area of the square = side²
The area of the square = n square feet
n = side²
Square root on both sides:
side = √n feet
Thus, the expression shows the side length, in feet, of the bulletin board is √n feet option (A) is correct.

Can someone please explain how they got 12??
Answer:
They got 12 by multiplying 3 × 4
Step-by-step explanation:
They used distributive property to multiply the 3 by each number in the parentheses
3 × x/3 = 1x = x
3 × 4 = 12
x + 12 = 6 × 3
They mutliplied 6 × 3 to get 18
x + 12 = 18
They then subtracted both sides by 12 to isolate the variable
x + 12 - 12 = 18 - 12
x = 6
Answer:
hope this helps! lmk if you still dont understand it!
:)
Step-by-step explanation:
you do 3*4 which gives you 12 and 3*x/3, but you should keep it as x
6*3 is 18
x+12=18 (solve for x)
-12=-12
x=6
check the answer:
3*(6/3+4)=6*3
3(2+4)=6*3
6+12=6*3
18=18
Sharon is planning a holiday for 4 people for 7 days
Here are the costs for the holiday for each person
Travel-£130 hotel-£60 for each day spending money-£350
Work out the total cost of the holiday for 4 people for 7 days
Answer:
3600
Step-by-step explanation:
Each PERSON cost:
Travel cost 130 (assume for whole 7 days since per day is not written)
Hotel 60 per day (so 7 days = 60 * 7 = 420)
Money Spend 350 (assume for whole 7 days since per day is not written)
-------------------------------------------------------------------------------------------------------------
Now, that sums to:
130 + 420 + 350 = £900 [each person for whole 7 days]
Now, there are 4 person, so total cost of whole group (4 persons):
900 * 4 = £ 3600

find the common ratio and the 12th term of the geometric sequence 64, 16, 4, ...
Answer:
common ration = 1/4
12th term = 1/65536
Step-by-step explanation:
64
64*1/4 = 16
16 * 1/4 = 4
4* 1/4 = 1
1 * 1/4 = 1/4
1/4*1/4 = 1/16
1/16*1/4 = 1/64
etc
1/256
1/1024
1/4096
1/16384
12th term = 1/65536
Answer:
see explanation
Step-by-step explanation:
The common ratio r is calculated as
[tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{16}{64}[/tex] = [tex]\frac{1}{4}[/tex]
The n th term of a geometric sequence is
[tex]a_{n}[/tex] = a₁[tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 64 and r = [tex]\frac{1}{4}[/tex] , thus
[tex]a_{12}[/tex] = 64 × [tex](\frac{1}{4}) ^{11}[/tex] = 64 × [tex]\frac{1}{4194304}[/tex] = [tex]\frac{64}{4194304}[/tex] = [tex]\frac{1}{65536}[/tex]

M<1=3x+7, m<5=5x-3. Find the value of each variable.
Answer: x=5
Step-by-step explanation:
To find the value of x, we set the measures of 1 and 5 equal to each other.
3x+7=5x-3 [subtract both sides by 5x]
-2x+7=-3 [subtract both sides by 7]
-2x=-10 [divide both sides by -2]
x=5
Now, we know that x=5.
