Step-by-step explanation:
The denominators are 2, 3, and 4. The least common denominator is the least common multiple (LCM) of these numbers.
To find the LCM, first write the prime factorizations.
2 = 2¹
3 = 3¹
4 = 2²
The LCM is therefore 2² × 3 = 12.
Rewrite the fractions with a denominator of 12.
⁷/₄ + ¹/₂ + ⁵/₃ + ¹/₃ + ¹/₄ + ¹/₂
= ²¹/₁₂ + ⁶/₁₂ + ²⁰/₁₂ + ⁴/₁₂ + ³/₁₂ + ⁶/₁₂
Now that the denominators are the same, we can simply add the numerators.
= ⁽²¹⁺⁶⁺²⁰⁺⁴⁺³⁺⁶⁾/₁₂
= ⁶⁰/₁₂
= 5

there are some coloured pins in a bag
Answers
Answer:
Green is 0.3, Yellow is 0.1
There are 12 green pins in the bag
Step-by-step explanation:
The probability is the ratio between the possible outcomes over the total outcomes
The value of the probability of possible outcomes is greater than 0 and smaller than 1 (0 < P < 1)The sum of the probabilities of all outcomes must equal 1∵ A bag contains some green, yellow, purple and grey pins
∵ The probability of picking a purple pin P(purple) = 0.35
∵ The probability of picking a grey pin P(grey) = 0.25
→ The total of all possible outcomes is 1
∴ The sum of the probability of green and yellow pins = 1 - 0.35 - 0.25
∴ The sum of the probability of green and yellow pins = 0.4
∴ P(green) + P(yellow) = 0.4 ⇒ (1)
∵ The probability of picking a green pin is 3 times the probability
of picking a yellow pin
∴ P(green) = 3 P(yellow) ⇒ (2)
→ Substitute (2) in (1)
∴ 3 P(yellow) + P(yellow) = 0.4
∴ 4 P(yellow) = 0.4
→ Divide both sides by 4
∴ P(yellow) = 0.1
∴ The probability of picking a yellow pin is 0.1
→ Substitute P(yellow) in (20 by 0.1
∴ P(green) = 3(0.1)
∴ P(green) = 0.3
∴ The probability of picking a green pin is 0.3
∴ Green = 0.3, Yellow = 0.1
∵ There are 14 purple pins in the bag
∵ P(purple) = 0.35
∴ 0.35 of purple pins = 14
→ To find the total number of pins in the bag divide 14 by 0.35
∴ The total number of pins = 14 ÷ 0.35
∴ The total number of pins = 40 pins
∵ P(green) = 0.3
∴ The number of green pins = 0.3 × 40
∴ The number of green pins = 12 pins
∴ There are 12 green pins in the bag

mary bought a blouse and a pair of jeans for 38.50 if jeans cost 12.50 more then the blouse how much did she pay for the jeans
Answers
Answer:
Blouse = $13.00
Jeans = $25.50
Step-by-step explanation:
x = blouse
y = jeans
x + y = 38.5
y = x + 12.5
Use substitution:
x + x + 12.5 = 38.5
2x = 26
x = 13
Blouse = $13.00
Jeans = $25.50
The price of Blouse is $13.00 and price of Jeans is $25.50.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let x represents the price of blouse and y represents the price of jeans.
mary bought a blouse and a pair of jeans for 38.50
x+y=38.5
jeans cost 12.50 more then the blouse
y=12.5+x
We need to find the price of jeans.
Substitute y value in above equation.
x + x + 12.5 = 38.5
Add the like terms
2x+12.5 = 38.5
Subtract 12.5 on both sides
2x = 26
Divide both sides by 2
x = 13
Hence, the price of Blouse is $13.00 and price of Jeans is $25.50.

Answer:
D. an infinite number of solutionsStep-by-step explanation:
In order to know that this is true, you must do simple steps to solve it. The first equation (y = 2 (x + 4)) is unsolved. In order to make it equal to the second equation (Y = 2 x + 8
), you must first use the distributive property, so multiply the x and the 4 in the first equation to get Y= (2x + 8), remove the parenthesis, and now, the equations are equal. Since they are equal, they overlap each other on the graph, so any number replacing x will change both equations equally, so they will forever overlap no matter what.
