Answer:
She isn't correct because after you find the common denominator, the numerator needs to be changed as well, so when she multiplied the denominator of 2/3 by 4 to get 12, she also had to multiply the 2 by 4, to get 8/12, and then subtracted, because otherwise, the new fraction isn't equivalent to the original fraction.
Solve these simultaneous equations:
6x + 8y = 36 6x + 5y = 27
Answer:
Y = 3
X = 2
Step-by-step explanation:
(6x2) = 12
(8x3) = 24
12 + 24 = 36
(6x2) = 12
(5x3) = 15
12 + 15 = 27

Lucy bought a fish tank shaped like a rectangular prism for her new betta fish. The tank holds 2,244 cubic inches of water. It is 12 inches long and 11 inches wide.
Answer:
The length of the fish tank is 17 inches.
Step-by-step explanation:
The volume of a rectangular prism is length × breadth × height.
You already know the volume, breadth, and height, so you can find the length.
Length = 2244 ÷ 12 ÷ 11
= 17 inches
The height of the tank is 17 inches.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
Given that,
The shape of the fish tank is rectangular prism.
The formula to calculate the volume of the rectangular prism is,
Volume = Length × Width × height
Given,
Volume of the tank = 2,244 cubic inches
Length = 12 inches
Width = 11 inches
Let x be the height.
Substituting the given values,
2,244 = 12 × 11 × x
x = 2244 / (12 × 11)
x = 2244 / 132
x = 17 inches
Hence the height of the tank is 17 inches.

Given
The price of a chainsaw is [tex]\$539.95[/tex]
The price of each safety chaps is [tex]\$69.95[/tex]
Total price before sales tax
[tex]\Rightarrow C=539.95+2\times 69.95\\\Rightarrow C=\$ 679.85[/tex]
with a tax of 5%, the total cost will be
[tex]\Rightarrow C_t=1.05C\\\Rightarrow C_t=1.05\times 679.85=\$ 713.84[/tex]
The ratio of boys to girls taking geometry this year is 27:31. If 246 students are ebrolled in geometry this year, approximately how many of them are boys and how many of them are girls?
Answer:
115 boys
131 girls
Step-by-step explanation:
Given data
The given ratio= 27:31
The sum of the ratio = 27+31= 58
The total number of students taking geometry= 246
Let us apply the part to all method
let the number of boys be x
27/58= x/246
cross multiply
58*x= 246*27
58x=6642
x= 6642/58
x=114.5
Hence the number of boys is 115
Thefore, the number of girsl= 246-115= 131

Which expression is equivalent to 2.8n – 8.4?
Answer:
4.1n
Step-by-step explanation:
Given the equation n – 4.6n – 3.3n + 2.8n , to get its equivalent expression, the following steps must be followed;
Step 1:
Factor out the common variable n
n(1 – 4.6 – 3.3 + 2.8)
Step 2:
Carry out the operation in parentheses;
= n(1+2.8-4.6-3.3)
= n(3.8-4.6-3.3)
= n(3.8-3.3-4.6)
= n(0.5-4.6)
= n(-4.1)
= -4.1n
The equivalent expression is -4.1n

Answer:
Step-by-step explanation:
If a number gets increased by scale factor = k
Then k > 1
If the number gets decreased by a scale factor 'k'
Then 0 < k < 1
Let numbers gets increased by the scale factor = 2,
And decreased by the scale factor = [tex]\frac{1}{2}[/tex]
Numbers Scale up by 2 Scale down by [tex]\frac{1}{2}[/tex]
0.05 0.05 × 2 = 0.1 0.05 × [tex]\frac{1}{2}[/tex] = 0.025
[tex]\frac{1}{2}[/tex] [tex]\frac{1}{2}\times 2 = 1[/tex] [tex]\frac{1}{2}\times \frac{1}{2}=\frac{1}{4}[/tex]
7 7 × 2 = 14 7 × [tex]\frac{1}{2}[/tex] = 3.5

You have found two job offers for the beginning of the summer. Each job is only 10 days long. Job Offer #1: The offer is to receive $0.25 for accepting the job. After day one you have made a total of $1, $4 total after two days of work, $16 total after three days, etc. Job Offer #2: The offer is $16 per day with no acceptance bonus. Write an equation to represent Job Offer #1 and Write an equation to represent Job Offer #2
Answer:
[tex]f(n) = \frac{4^n-0.25}{3}[/tex] --- Job offer 1
[tex]g(n) = 16n[/tex] --- Job offer 2
[tex]1 \le n \le 10[/tex]
Step-by-step explanation:
Given
Job offer 1:
Offer = $0.25
[tex]Day 1 = \$1\ Day 2 = \$4\ Day 3 = \$16......[/tex]
Job offer 2:
Daily = $16
Required
Determine the equation for both jobs
For job offer 1:
Considering the pay for day 1, day 2,....
The sequence shows a geometry progression where the payment between subsequent days is a product of 4 by the payment of the previous day.
The sequence can be represented as:
[tex]T_1 = 1; T_2 = 4; T_3 = 16[/tex]
The common ratio (r) is:
[tex]r = \frac{T_2}{T_1} = \frac{4}{1} = 4[/tex]
The sum of n terms is the total salary received in n days.
[tex]S_n = \frac{a(r^n - 1)}{r-1}[/tex]
[tex]S_n = \frac{1 * (4^n - 1)}{4-1}[/tex]
[tex]S_n = \frac{4^n - 1}{3}[/tex]
So, the equation for job offer 1 is:
[tex]f(n) = Offer + S_n[/tex]
[tex]f(n) = 0.25+ \frac{4^n - 1}{3}[/tex]
Take LCM
[tex]f(n) = \frac{0.75 + 4^n - 1}{3}[/tex]
Collect like terms
[tex]f(n) = \frac{4^n - 1+0.75}{3}[/tex]
[tex]f(n) = \frac{4^n-0.25}{3}[/tex]
For job offer 2:
Daily payment of $16 implies that job offer 2 pays 16n for n days.
So:
[tex]g(n) = 16n[/tex]
In both cases: [tex]1 \le n \le 10[/tex]

Which of the following correctly completes the square for: x^2+2x=48
A. (x+2)^2=52
B. (x+1)^2=49
C. (x+2)^2=47
D. (X-1)^2=26
Answer:
(x+1)²= 49, the answer is B
Step-by-step explanation:
x² + 2x = 48
x² + 2x + (2/2)² - (2/2)²= 48 --[what we are trying to do is to complete a square by adding (2/2)² - (2/2)²]
(x+1)²= 49, the answer is B
Answer:
hey I'm pretty sure it's B. (x+2)²=49
Step-by-step explanation:
x²+2x+(2\2)²=48 + (2\2)²
(x+1)²=49
