The sum of three consecutive even numbers is 138. Find the numbers.
Answers
The next consecutive even number is the very next even number in the sequence; this can be determined by adding two to the first even number. That means that the next consecutive even number after “n” is “n+2”. The same thing holds for the following even number, except this time it’s “n+2+2” or “n+4”.
We are told that the sum of these three consecutive even numbers is 138. If we write this in the form of an equation, we have:
138 = n + (n+2) + (n+4)
Now, simplify and solve for n:
138 = 3n + 6; 132 = 3n; n = 44.
The first even number is 44, and the two following are 46 (44 + 2) and 48 (44 + 4).

4. 2 1/2 - 1 5/6 =1/6
Answers
1/2 + 3/4 = 3/4 ........... false, so we do not add anything
5/8 - 1/4 = 3/8 ............ true, so we have (10 * 3/8) = 15/4
4/5 + 7/10 = 1 1/2 ....... true, so we have (10 * 1 1/2) = 15
2 1/2 - 1 5/6 = 1/6 ...... false, so we do not add anything.
we are then left with 15/4 and 15, on adding all together, we have
100 + 15/4 + 15 = 118.75

Step-by-step explanation:
Answer:
[tex]y=224-16x[/tex]
Step-by-step explanation:
Stare at the table for a bit. if you look at the y you can tell that the difference between two rows is the same, and it's equal to 32: every time x increases by 2, y decreases by 32; it means that if x increased by 1, y would decrease by 16. At this point we can write the equation as [tex]y=q-16x[/tex] To find q there are 2 ways: one is to plug the value from any line in place of y and x, or, more elegant, is to backtrack the table: if y goes down by 32 when x raises by 2, it emans that if x decreases by 2, y will go up by 32. And 192+32 is 224, our q value.

Step-by-step explanation:
We can use the quadratic formula or factor, This looks hard to factor so we should use the quadratic formula.
ax^2 + bx + c
so
a=4
b=-9
c=2
you can try it by hand or use this:
https://www.calculatorsoup.com/calculators/algebra/quadratic-formula-calculator.php
you get x=2 and x=0.25 these are the x intercepts (where Y is zero and where the graph crosses the x axis)
so mark x=2 and x=0.25 with a dot on a number line and you can draw a straight line between them since that is the part of the graph that is below the x axis (because the equation has <0) it is a positive parabola because the "a" value is positive and the presence of a "b" value means part of the graph will be below the x axis

a bag contains 300 balls. 96 balls are yellow. Which answer shows both the correct proportion and the correct percent of yellow balls in the bag.
Answers
The proportion of yellow balls in the bag is 8/25 and percentage is 32 %
What is Percentage and Proportion?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
Given data ,
The number of balls in the bag = 300
The number of yellow balls in the bag = 96
The proportion of yellow balls =
The number of yellow balls in the bag / The number of balls in the bag
The proportion of yellow balls = 96 / 300
= 24 / 75
= 8 / 25
Therefore , The proportion of yellow balls in the bag is 8 / 25
Now ,
The percentage of yellow balls in the bag =
Number of yellow balls in the bag / Number of balls in the bag x 100 %
The percentage of yellow balls in the bag = ( 8 / 25 ) x 100 %
= 8 x 4 %
= 32 %
Hence ,
The proportion of yellow balls in the bag is 8/25 and percentage is 32 %

7 hamsters at 5 pesos each and 13 hamsters at 8 pesos each
Step-by-step explanation:
5x + 8y = 139
x + y = 20
x = 20 - y
5x + 8y = 139
5(20 - y) + 8y = 139
100 - 5y + 8y = 139
100 + 3y = 139
3y = 139 - 100
3y = 39
3y/3 = 39/3
y = 13
x + y = 20
x + 13 = 20
x = 20 - 13
x = 7
