Alvin's age is three times Elga's age. The sum of their ages is 112. What is Elga's age?
Answer:
Elga is 37 years old
Step-by-step explanation:
(A shame they are not the same age but that would be too easy...)
So... they both equal 112 and one of them (Alvin) is 3 times older
Basically just divide 112 and 3
Answer : 37 years old
Check Work
112 - 37 = 75
75 + 37 = 112

Jacob conducted a music survey among his friends. He reported that 0.42 prefer pop, 22% prefer rock, and 2/5 prefer hip hop, Explain what's wrong with Jacob's results. ASAP PLS
Answer:
Step-by-step explanation:
Based on ur graph, in a class of 90 students (20 rock, 40 hip hop, and 30 country...added = 90) , 30 chose country....30/90 reduces to 1/3.....so 1/3 chose country.
In a class of 450 students......1/3 * 450 = 450/3 = 150 chose country
Answer:
The total percentages do not equal 100%, they equal 102%. If all friends answered, his total should equal 100%
Step-by-step explanation:
0.42 is 42%, 22% is 22%, and 2/5 is 0.4 which is 40%. Together that is 102%. If all friends answered, his total should equal 100%

5a/8ab = ?/ 24a^2 b
9514 1404 393
Answer:
? = 15a^2
Step-by-step explanation:
We assume you want
(5a)/(8ab) = (?)/(24a^2·b)
Multiplying by 24a^2·b, we get ...
(5a)/(8ab)·(24a^2·b) = ? = 15a^2

If there are 3.28 feet in a meter , how many are in the 110 meter dash?
In 110 meter dash, there are 360.8 feet.
What is Simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
Given that, there are 3.28 feet in a meter
Since,
in 1 meter there are = 3.28 feet
Thus in 110 meters there are = 3.28 * 110 feet
In 110 meters, there are = 360.8 feet
Therefore, there are 360.8 feet in 110 meters dash.

-7x-14=2x+13 What does x equal?
Answer: x = -3
Step-by-step explanation:
Given
-7x - 14 = 2x + 13
Subtract 2x on both sides
-7x - 14 - 2x = 2x + 13 - 2x
-9x - 14 = 13
Add 14 on both sides
-9x - 14 + 14 = 13 + 14
-9x = 27
Divide -9 on both sides
-9x / -9 = 27 / -9
[tex]\boxed {x = -3}[/tex]
Check:
Left-hand side = -7x - 14
= -7 (-3) - 14
= 21 - 14
= 7
Right-hand side = 2x + 13
= 2 (-3) + 13
= -6 + 13
= 7
7 = 7

O M ZABC = 60°
OM ABC = 67°
OM ZABC = 120°
O M ABC = 127°
Answer:
∠ ABC = 127°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ ABC is an exterior angle of the triangle , then
∠ ABC = ∠ BDC + ∠BCD = 60° + 67° = 127°
We know that we have a triangle and we want to find the value of its angle which will be given by 53°.
We know that the sum of all the interior angles of a triangle must equal 180 degrees, so we find then:
[tex]ABC=180[/tex]
Now making the sum of the angles already known and equating to 180, we find that:
[tex]180=67+60+x\\x=180-127\\x= 53[/tex]

4 – 2(x + 7) = 3(x + 5)
Answer:
x = -5
Step-by-step explanation:
4 – 2(x + 7) = 3(x + 5)
Distribute
4 - 2x-14 = 3x+15
Combine like terms
-2x-10 = 3x+15
Add 2x to each side
-2x-10 +2x= 3x+15+2x
-10 = 5x+15
Subtract 15 from each side
-10-15 = 5x+15-15
-25 = 5x
Divide by 5
-25/5 = 5x/5
-5 =x
Answer:
x = -5
Step-by-step explanation:
4 - 2(x + 7) = 3(x + 5)
so, let's do the multiplications. remember, when two terms are multiplied, then everything of the left is multiplied with everything on the right. and a "-" flips signs.
2(x + 7) = 2x + 14
3(x + 5) = 3x + 15
so, in total
4 - 2x - 14 = 3x + 15
now, we add combinable things together, and we can also move things from one side of the equation to the other (by adding our subtracting the same thing on both sides, so that the value of the expression remains unchanged).
-2x - 10 = 3x + 15
-25 = 5x
and now, what applied to adding and subtracting also aims to multiplication and division. again, it is important to do the same thing to both sides.

Step-by-step explanation:
The average number of words on the page is 300. Because there are 59,540 words and 59540/300 = 198.46 (approximately), there are 199 pages in the book (because the 0.46 pages would be the last page).

Answer:

Step-by-step explanation:
I find the easiest way to draw a graph is to let a graphing calculator do it. That result is shown in the attachment.

If you're drawing this by hand, it can be easier if it is simplified a bit.
2(x +1) = 3(y -1) -4
2x +2 = 3y -3 -4 . . . . . . eliminate parentheses
2x +9 = 3y . . . . . . . . . . add 7
y = 2/3x +3 . . . . . . . . . divide by 3
This is the equation of the line in slope-intercept form. It tells you that the point (0, 3) on the y-axis is on the line, and that it has a slope of 2/3. That means it has a rise/run of 2/3, or a rise of 2 units for each 3 units to the right.
Starting from point (0, 3), another point on the line will be 3 over and 2 up, at (3, 5). Once you have a couple of points plotted, you can draw the line through them to make your graph.
