Answer:
x=2, y = -4.
or as an ordered pair it is (2, -4).
Step-by-step explanation:
-x + 6y = -26
x + 5y = -18 Add these 2 equations to eliminate x:
0 + 11y = -44
y = -44/11 = -4.
Now substitute y = -4 in the first equation:
-x + 6(-4) = -26
-x - 24 = -26
-x = -26 + 24 = -2
x = 2.
Check the result by substituting in equation 2:
x + 5y = 2 + 5(-4) = 2 - 20 = -18 - checks out.

Answer:
arwa
Step-by-step explanation:
A scalene triangle has no equal length sides. It also has no equal inside angles. These triangles can be acute (all angles less than 90°), right-angled (one angle is 90°), or obtuse (one angle is more than 90°)
Answer:
Right scalene triangle
Step-by-step explanation:
Scalene triangles have no equal sides. A right scalene triangle has no equal sides, and one right angle.
The length of 12cm and 5 cm missing one
Answer:
13cm
Step-by-step explanation:
Let the given lengths be the opposte amd adjacent sides of a right triangle'
The missing side will be the hypotenuse
Using the pythagoras theorem;
hyp^2 = 5² + 12²
hyp² = 25 + 144
hyp² = 169
hyp =√169
hyp = 13cm
Hence the missing one is 13cm

find the value of x pls help
Answer:
x = 16
Step-by-step explanation:
*A triangle's interior angles always add up to 180 degrees*
1. The square on the left-hand side means 90 degrees
2. To find the degrees on the 150 degrees side we need to subtract 180 from 150 as the line it's on equals 180 degrees
180 -151 = 29
3. Now we know 3 out of the two angles, so if we add them up and subtract them from 180 degrees we will have the 3rd angle
29 +90 = 119
180 - 119 = 61
4. Now we can put that in with the equation
4x + 3 = 61
5. Solve
4x - 3 = 61
+ 3 +3
4x = 64

The mean age of the employees at a large corporation is 35.2 years, and the standard deviation is 9.5 years. A random sample of 4 employees will be selected. What are the mean and standard deviation of the sampling distribution of the sample mean for samples of size 4
Answer:
35.2 ; 4.75
Step-by-step explanation:
Given that :
Mean age, μ = 35.2 years
Standard deviation, σ = 9.5 years
The mean of the sampling distribution will be equal to the population mean, μ, this is according to the central limit theorem.
The standard deviation of the sampling distribution, is given by : σ/√n
n = sample size = 4
SD of sampling distribution = 9.5/√4 = 9.5 / 2 = 4.75

Two points A and B on a plan represent two localities 12 m apart. Given that the segment AB is 6cn long, find the scale used to draw the plan.
Answer:
The scale is 1:200
Step-by-step explanation:
On the plan we have the drawing as 6 cm
In real representation, we have the distance as 12 m
Firstly we have to convert to same unit
In this case, we use the cm for convenience
Mathematically, 100 cm is 1 m
Thus, 12 m
will be 12 * 100 = 1,200 cm
So, we have the ratio as;
6 cm : 1,200 cm
and that is 1:200 (since 6/1200 = 1/200 and in ratio form, we have that as 1:200)
Craig earns the same amount of money each month. His telephone bill is 1/20 of his monthly earnings, and he pays a total of $720 each year for his telephone service. How much does Craig earn each month, in dollars?
Question 3 options:
$1,200
$1,600
$60
$120
Answer:
Hello! answer: 1,200
Step-by-step explanation:
We know he pays 720 in a year so i divide that by 12 so... 720 ÷ 12 = 60 so he pays 60 each month for his telephone service since thats only 1/20 of his earning what I do is 60 × 20 and we get 1200 so craig makes 1200 a month hope that helps!
$1200, Craig earns each month.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Let's assume Craig earns $x per month.
The telephone bill is 1/20 of his monthly earnings, which is (1/20)x.
He pays a total of $720 each year for his telephone service.
Since there are 12 months in a year,
he pays (1/12) * 720 = $60 per month for his telephone service.
Therefore,
(1/20)x + $60 = x,
as he earns the same amount each month.
Simplifying the equation,
we get x/20 = $60
Multiplying both sides by 20,
we get x = $1,200
Therefore, Craig earns $1,200 per month.

If the principal is $4,500 and the rate of interest is 8%, what is the amount of interest after one year? Formula is I =PRT
Step-by-step explanation:
I=?
P= $4500
R=8%=0.08
T=1 year
8%*0.01= 0.08
I=(4500)(0.08)(1)
(4500)(0.08)=360
360*1=360
The interest after one year is $360
A 70 cm long stick is cut into two parts in such a way that the longer part is 20 cm longer than the shorter part. How long is each part?
Answer:
Long part= 45
Short part= 25
Step-by-step explanation:
Let the short part of the stick be x
Let the long part be x+20
The total length of the stick is 70cm
x + (x+20)= 70
x+x+20= 70
2x+20= 70
2x= 70-20
2x= 50
x= 50/2
= 25
Longer part length= 20+25
= 45
The short part is 25

A chipmunk population is experiencing exponential growth with a population growth rate of 265 individuals/year, and a per capita rate of increase of 0.15. How many chipmunks are currently in this population
Answer:
There are 1766 chipmunks in the population
Step-by-step explanation:
Number of individuals increasing per year = 265
Rate of increase = 0.15
Rate of increase = increase in number of individuals in a given population /total population
Substituting the given values, we get -
0.15 = (265/total population)
Total population = 265/0.15 = 1766
