Rewrite each fraction with a denominator of 24 2/3 5/8
Answer:
A)16/24
B)15/24
Step-by-step explanation:
We were told to rewrite so that the denominator will be 24
A)2/3
This can be rewritten as 16/24, so that the denominator is now 24. And if we divide the numerator (16) by factor of 8 and the denominator (24) by factor of 8. Then we have 2/3.
OR
[2/3 × 8/8] = 16/24
B)5/8
This can be rewritten as 15/24, so that the denominator is now 24. And if we divide the numerator (15) by factor of 3 and the denominator (24) by factor of 3. Then we have 5/8
OR
(5/8 × 3/3)= 15/24

I need help finding the missing side.
Answer:
x ≈ 25.1
Step-by-step explanation:
Using the cosine ratio in the right triangle, that is
cos64° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{11}{x}[/tex] ( multiply both sides by x )
x × cos64° = 11 ( divide both sides by cos64° )
x = [tex]\frac{11}{cos64}[/tex] ≈ 25.1 ( to the nearest tenth )

Tim is going to an amusement park that cost 30.00 to get into.Treats like cotton candy carmel apples and funnel cakes cost 2.00 dollars each .Tim does not want to spend more than 62.00 in all. Solv for x ,where x equals the number of 2.00 treats tim can buy
Answer:
x = 16 treata
Step-by-step explanation:
Let us represent x = Number of treats that Tim can buy
We are told that: Tim does not want to spend more than $62.00 in all.
= Time wants to spend less than or equal to $62.00
Tim is going to an amusement park that cost $30.00 to get into.Treats like cotton candy carmel apples and funnel cakes cost 2.00 dollars each .
Therefore, our inequality equation =
$30.00 + $2.00 × x ≤ $62.00
30 + 2x ≤ 62
Solving for x
30 + 2x ≤ 62
2x ≤ 62 - 30
2x ≤ 32
x ≤ 32/2
x ≤ 16
Hence, Tim can buy no more than(less than or equal to ) 16 treats
Perrie invests £25000 for 3 years in a saving account. She gets 2.7% per annum compound interest. Calculate the total amount of interest perrie will get after 3 years.
Answer:
I (interest) = £ 2,080.17
Step-by-step explanation:
Perrie invests £25000 for 3 years in a saving account. She gets 2.7% per annum compound interest. Calculate the total amount of interest perrie will get after 3 years.
To solve the above question, we would use the Periodic compound interest formula
A = P(1 + r) ^t
Where P = Principal = £25000
r = Interest rate = 2.7 % = 0.027
t = time in years = 3 years
Hence:
A = £25,000( 1 + 0.027)³
A = £27,080.17
A = P + I where
P (principal) = £ 25,000.00
I (interest) = £27,080.17 - £ 25,000.00
I (interest) = £ 2,080.17
The total amount of interest perrie will get after 3 years is £ 2,080.17
what choice is a solution to the system of equations? y=2x-3 y-9=-x
Answer:
[tex](4,5)\ or\ x=4,y=5[/tex]
Step-by-step explanation:
[tex]We\ are\ given:\\y=2x-3\\y-9=-x\\Now,\ lets\ separate\ all\ the\ constant\ terms\ to\ the\ RHS\ and\ the\ variable\\ terms\ to\ the\ LHS.\\Hence,\\y-2x=-3\\y+x=9\\By\ subtracting\ the\ two\ equations:\\(y-2x)-(y+x)=(-3)-(9)\\Hence\ lets\ simplify\ this\ main\ equation: \\y-2x-(y+x)=-3-9\\y-2x-y-x=-12\\-3x=-12\\x=\frac{-12}{-3}=4\\\\Now,\ lets\ consider\ the\ second\ equation\ in\ the\ solution:\\y-9=-x\\Substituting\ x=4,\\y-9=-(4)\\y-9=-4\\y=-4+9\\y=5\\[/tex]
[tex]Now,\\We\ get\ the\ solution\ to\ this\ system\ of\ equations:\\x=4,y=5\\By\ putting\ this\ as\ a\ co-ordinate\ pair (x,y):\\(4,5)[/tex]
Answer:
The solution of the system of equations will be:
[tex]y=5,\:x=4[/tex]
Step-by-step explanation:
Given the system of equation
[tex]\begin{bmatrix}y=2x-3\\ y-9=-x\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}y-2x=-3\\ y+x=9\end{bmatrix}[/tex]
so
[tex]y+x=9[/tex]
[tex]-[/tex]
[tex]\underline{y-2x=-3}[/tex]
[tex]3x=12[/tex]
so the system of equations becomes
[tex]\begin{bmatrix}y-2x=-3\\ 3x=12\end{bmatrix}[/tex]
solve 3x=12 for x
[tex]3x=12[/tex]
Divide both sides by 3
[tex]\frac{3x}{3}=\frac{12}{3}[/tex]
[tex]x=4[/tex]
[tex]\mathrm{For\:}y-2x=-3\mathrm{\:plug\:in\:}x=4[/tex]
[tex]y-2\cdot \:4=-3[/tex]
[tex]y-8=-3[/tex]
Add 8 to both sides
[tex]y-8+8=-3+8[/tex]
[tex]y=5[/tex]
Thus, the solution of the system of equations will be:
[tex]y=5,\:x=4[/tex]

Mr Brown has 2 children are going to london by train 1 adult costs £24 and child ticket costs 12 1/3 off adults tickets and 60% off child ticket
Complete Question
Mr Brown has 2 children are going to london by train
1 adult costs £24 and child ticket costs 12
The Family Railcard offers:
1/3 off adults tickets and 60% off child ticket
What is the total cost of tickets when Mr Brown uses the Family Railcard
Answer:
£25.60
Step-by-step explanation:
From the question:
1 adult costs £24
The Family Railcard offers:
1/3 off adults tickets.
Hence:
1/3 × £24 = £8
The cost for Mr Brown = £24 - £8
= £16
Child ticket costs £12
The Family Railcard offers:
60% off child ticket
Hence = 60% × £12
= 60/100 × £12
= £7.2
The cost for 1 child = £12 - £7.2
= £4.8
The total cost of tickets when Mr Brown uses the Family Railcard is:
Cost for Mr Brown + Cost for his 2 Children
£16 + 2 × £4.8
£16 + £9.6
= £25.60
The graph shows the relationship between the number of pounds of
apples purchased and the total cost of the apples.
What is the cost of 1 pound of apples? Enter the answer in the box.
Given:
The graph shows the relationship between the number of pounds of apples purchased and the total cost of the apples.
To find:
The cost of 1 pound of apples.
Solution:
We need to find the slope of the line to get the cost of 1 pound of apples.
From the given graph it is clear that the line passes through two points (0,0) and (2,3). So, the slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{3-0}{2-0}[/tex]
[tex]m=\dfrac{3}{2}[/tex]
[tex]m=1.5[/tex]
Therefore, the cost of 1 pound of apples is $1.5.

Answer:
120°
Step-by-step explanation:
m<ABD+m<DBC=m<ABC
61°+59°=120°
hope this helped!
Answer:
We conclude that the value of m∠ABC = 120°
Step-by-step explanation:
Given
m∠ABD = 61°
m ∠DBC = 59°
To Determine
m∠ABC = ?
It is clear that the value of m∠ABC can be determined by adding m∠ABD and m∠DBC because m∠ABC the segment BD divides the angle m∠ABC into two adjacent angles m∠ABD and ∠DBC.
Therefore,
m∠ABC = m∠ABD + m∠DBC
= 61° + 59° ∵ m∠ABD = 61°, m ∠DBC = 59°
= 120°
Therefore, we conclude that the value of m∠ABC = 120°

Ms. Albero decided to make juice to serve along with the pizza at the Student Government party. The directions said to mix 3 scoops of powdered drink mix with 1 gallon of water to make each pitcher of juice. One of Ms. Albero’s students said she will mix 12 scoops with 3 gallons of water to make 4 pitchers. How can you use the concept of proportional relationships to decide whether the student is correct?
Answer:
the student is wrong
Step-by-step explanation:
the og directions said 3 scoops / 1 gallon / 1 pitcher. if you are using 12 scoops, then the gallons of water will be proportional, meaning 3x4=12 scoops / 1x4=4 gallons / 1x4=4 pitchers. if you x4 to one of them, then the directly porportinal values also have to be multiplied by the same number, hence making the student wrong since they should have 4 gallons for 12 scoops

Step 1: Define
-12(x + 4) + 14x = 60
Step 2: Solve for x
Distribute -12: -12x - 48 + 14x = 60Combine like terms: 2x - 48 = 60Add 48 to both sides: 2x = 108Divide 2 on both sides: x = 54Answer:
x = 54
Step-by-step explanation:
-12(x + 4) + 14x = 60
i) distribute -12 to the whole parentheses of (x+4)
(-12 × x) + (-12 × 4) + 14x = 60
-12x - 48 + 14x = 60
ii) collect like terms
-12x + 14x - 48 = 60
2x - 48 = 60
iii) move constant to the right-hand side and change its sign
2x = 60 + 48
iv) add the numbers
2x = 108
v) divide both sides of the equation by 2
[tex] \frac{2x}{2} = \frac{108}{2} [/tex]

Answer: d) b = 12
2/3.b - 1/3.b + 12 = 16
⇔ 1/3. b = 16 - 12
⇔ 1/3.b = 4
⇔ b = 4.3 = 12
Step-by-step explanation:
Answer:
b = 12
Step-by-step explanation:
2/3 b - 1/3 b + 12 = 16
or, 2b/3 - b/3 + 12 = 16
or, 2b -b/ 3 + 12 = 16
or, 2b - b = 16 - 12
or, b = 4 × 3
therefore, b = 12
