When you were playing the integer game the first two cards that were selected were -8 and -10. What is the value in your hand?
Write an equation to justify your answer
what is the distance of the sum from -8
Answer:
The value in your hand is -18
let the value be x, then the equation is:
x = -8 + (-10)
x = - 8 - 10
x = - 10
the distance of the sum from -8 is the distance between -8 & -10, i.e -8 - (-10) = 2.
Mabel, Adeline and Charlie share 34500ft2 of land Mabel ownes 26%of the land area and Adeline Owens 47% of the land area . What is the land area that charlie owns ?
Answer:
Charlie owns 9,315 ft2 of the land area
Step-by-step explanation:
There are 34,500 ft2 of land shared between Mabel, Adeline, and Charlie.
Mabel owns 26% of the land area, that is:
26*34,500 ft2 / 100 = 8,970 ft2
Adeline owns 47% of the land area, or:
47*34,500 ft2 / 100 = 16,215 ft2
The land owned by Mabel and Adeline is: 8,970 ft2 + 16,215 ft2 = 25,185 ft2
Since the total area land is 34,500 ft2, Charlie owns:
34,500 ft2 - 25,185 ft2 = 9,315 ft2
Charlie owns 9,315 ft2 of the land area

Which number can be distributed across two terms inside parentheses
Answer:
3/5 is the number that can be distributed across two terms inside parentheses.
you might not need it but:
x = 5
Step-by-step explanation:
3/5(x - 10) = 18 - 4x - 1
using distributive property, open the parentheses:
3/5x - 6 = 18 - 4x - 1
Simplify:
3/5x + 4x = 17 + 6
4⅗x = 23
x = 5

Solve the inequality 3x + 4 < 22
Answer:
3х<18
х<6
хє(-infinity ;6);
Answer:
x<6
Step-by-step explanation:
3x+4<22
First, subtract 4 from both sides of the inequality.
3x-4<22-4
This cancels out the 4, so the 3x is isolated
3x/3<18/3
Finally, simplify to get the answer.
x<6

In a group of five students who took the same test, four of the scores were 85, 92, 81, and 95. If the average of the five students was 89, what was the score of the fifth student?
Answer:
92
Step-by-step explanation:
89 x 5 = 445
85 + 92 + 81 + 95 = 353
445 - 353 = 92
The score of the fifth student is 92.
What is an average?An average is a single number taken as representative of a list of numbers, usually the sum of the numbers divided by how many numbers are in the list.
Now it is given that,
Average of the five students = 89
Scores of four students = 85, 92, 81, and 95
Number of students = 5
Let the score of fifth student be x.
⇒Average of the five students = scores of five students/Number of students
∵scores of five students =Scores of four students + score of fifth student
∴scores of five students = 85+92+81+95+x
⇒scores of five students = 353+x
∴Average of the five students = (353+x)/5
⇒89 = (353+x)/5
or, 445 = 353+x
or, x = 445 - 353
⇒ x = 92
Hence, the score of the fifth student is 92

Write another ratio that’s is equilevent too.4:6 and how do u know that your new ratio is equivelant too 4:6
Answer:
8:12
Step-by-step explanation:
Another ratio that is equivalent to 4:6 would be 8:12;
To find another ratio equivalent to another, simply find the multiples of the numbers that make up the ratio.
Using 2 as multiplier;
2 ( 4 : 6) = 8 : 12
I am sure of this because when we reduce both ratio to their lowest term, we get the same value;
4: 6 8: 12
divide by 2 divide by 4

HK bisects GHJ. Find GHK and KHJ. Angle JHG measures 161
Answer: m∠GHK=80.5,
m∠KHJ=80.5
Step-by-step explanation:
Answer:
I would say both GHK and JHK equal 80.5 degrees. (if it is allowed with decimals).
Step-by-step explanation:
Bisectors are lines that basically cut an angle in half. Since JHG is the whole angle, the bisector, HK, halves it. So, both GHK and KHJ should be the same, since they both are half of the original angle. As a result, 161 divided by 2 is 80.5 degrees.

(d-2) What are the limits for outliers? (Round your answers to 1 decimal place. Negative amounts should be indicated by a minus sign.)
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data :
114, 261, 319, 183,654,313,58,98,335,324,52,125,342,66,321,893,690,798,201,74,632,216,76,155,161,304,530,1110,93,631,75,344,264,1120,122,45,304,192,316,63
USING CALCULATOR :
The mean(m) of the data: = ΣX/n
n = sample size = 40
m = 12974/40
m = 324.4
Median = ((n + 1)/2) th term = 41/2 = (20 + 21)th term / 2
= (261 + 264) / 2 = 262.5
Standard deviation (s) = sqrt(Σ(x - m)²/n))
s = 281. 74
B.) Coefficient of skewness (Ks) :
3(mean - median) / standard deviation
3(324.4 - 262.5) / 281.74
= 0.66

Marissa has $4.70 in quarters and dimes. If she has 9 more quarters than dimes, how many of each coin does she have?
dimes
quarters
Answer:
22 dimes
10 quarters
Step-by-step explanation:
$4.70 = 0.25(q + 9) + 0.1d
4.7 = 0.25q + 0.25(9) + 0.1d
4.7 = 0.25q + 2.25 + 0.1d
2.45 = 0.25q + 0.1d
24.5 = 2.5 + d
22 = d = 22 dimes
$4.70 = 0.25(q + 9) + 0.1(22)
4.70 = 0.25q + 0.25(9) + 2.2
4.70 = 0.25q + 2.25 + 2.2
4.70 = 0.25q + 2.25 + 2.2
4.70 = 0.25q + 4.45
0.25 = 0.25q
1 = q
1 q + 9 q = 10 quarters
Check:
$4.70 = 0.25(q + 9) + 0.1(d)
$4.70 = 0.25(1 + 9) + 0.1(22)
$4.70 = 0.25(10) + 0.1(22)
$4.70 = 2.5 + 2.2
$4.70 = 4.7
