Ordered pair for 3x + 5y = 2
9x + 11y = 14
Answers
Answer:
y = -3/5x +2 y = -9/11 + 14
Step-by-step explanation:
3x + 5y = 2(subtract 3x on both sides)
5y = -3x +2(divide by 5)
y = -3/5x + 2
9x + 11y = 14 (subtract 9x on both sides)
11y = -9x + 14 (divide by 11)
y = -9/11x + 14
Answer:
Step-by-step explanation:
-9x - 15y = -6
9x + 11y = 14
-4y = 8
y = -2
3x + 5(-2) = 2
3x - 10 = 2

Hannah has a bag that contains orange chews, lemon chews, and lime chews. She performs an experiment. Hannah randomly removes a chew from the bag, records the result, and returns the chew to the bag. Hannah performs the experiment 74 times. The results are shown below:
An orange chew was selected 39 times.
A lemon chew was selected 17 times.
A lime chew was selected 18 times.
Based on these results, express the probability that the next chew Hannah removes from the bag will be orange chew as a decimal to the nearest hundredth.
Answers
Based on these results, probability that the next chew Hannah removes from the bag will be orange chew is 0.53.
What is the probability of picking an orange chew?Probability determines how likely it is that event would occur. The probability that an event would occur lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
The probability of picking an orange chew = 39 / 74 = 0.53

Answers
Based on the definition of isosceles triangle, the value of x in the given diagram is: 84°.
What is an Isosceles Triangle?An isosceles triangle has two base angles of equal length.
Given that, a = 22°, and using the information in the image attached below, we have the following:
m∠1 = a = 22° (base angles)
m∠2 = a + m∠1 = 22 + 22 = 44° (external angle theorem)
m∠3 = m∠2 =44° (base angles)
m∠4 = 180 - (180 - m∠2 - m∠3) - m∠1 = 180 - (180 - 44 - 44) - 22
m∠4 = 70°
m∠5 = m∠4 = 70° (base angles)
m∠6 = 180 - (180 - m∠5 - m∠4) - m∠3
m∠6 = 180 - (180 - 70 - 70) - 44
m∠6 = 96°
m∠7 = m∠6 = 96° (base angles)
x = 180 - m∠7
x = 180 - 96
x = 84°
Therefore, based on the definition of isosceles triangle, the value of x in the given diagram is: 84°.

A bus makes a stop at 2:30, letting off 13 people and letting on 4. The bus makes another stop ten minutes later to let off 2 more people. How does the number of people on the bus after the second stop compare to the number of people on the bus before the 2:30 stop?
Answers
Answer:
The original number of passengers on the bus decreased by 10 after the second stop
Now, at 2:30:
15 passengers got off and 9 got on.
This means that:
number of passengers = x - 15 + 9
number of passengers = x -6
10 minutes later:
4 passengers got off the bus
This means that:
number of passengers = (x-6) - 4
number of passengers = x - 10
By comparing, we can note that:
The original number of passengers on the bus decreased by 10 after the second stop

The GCF of 12 and 28 is _____.
Answers
greatest common factor 12 and 28 is 4
The greatest common factor (GCF) of 12 and 28 is 4.
To find the GCF, you can determine the factors of both numbers and identify the greatest common factor they share.
As we know that a factor is a number that entirely divides another number.
To put it another way, any two integers that multiply to generate a result are factors of the result.
For 12, the factors are 1, 2, 3, 4, 6, and 12.
For 28, the factors are 1, 2, 4, 7, 14, and 28.
The common factors of 12 and 28 are 1, 2, and 4.
Among them, the greatest common factor is 4.
Therefore, the GCF of 12 and 28 is 4.
