-12x+9y=7
3x+4y=2
Show all workings please
Answer:
x = -2/15 & y = 3/5
Step-by-step explanation:
- 12x + 9y = 7 ...(1) ; 3x + 4y = 2 ...(2)
Multiply both sides of (2) by 4:
12x + 16y = 8
Add the new equation & (1):
12x + 16y = 8
-12x + 9y = 7
0 + 25y = 15 => y = 15/25 = 3/5
Thus, substitute the value of y in (2):
3x + 4y = 2 => 3x = 2 - 4(3/5) = (10-12)/5
=> 3x = -2/5
=> x = - 2/15
Answer:
[tex]x=-\frac{2}{15}=-0.133333333\\y = \frac{3}{5}= 0.6[/tex]
Step-by-step explanation:
−12x+9y=7
3x+4y=2
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
−12x+9y=7,3x+4y=2
To make −12x and 3x equal, multiply all terms on each side of the first equation by 3 and all terms on each side of the second by −12.
3(−12)x+3×9y=3×7,−12×3x−12×4y=−12×2
Simplify.
−36x+27y=21,−36x−48y=−24
Subtract −36x−48y=−24 from −36x+27y=21 by subtracting like terms on each side of the equal sign.
−36x+36x+27y+48y=21+24
Add −36x to 36x. Terms −36x and 36x cancel out, leaving an equation with only one variable that can be solved.
27y+48y=21+24
Add 27y to 48y.
75y=21+24
Add 21 to 24.
75y=45
Divide both sides by 75.
y=3/5
Substitute 3/5 for y in 3x+4y=2. Because the resulting equation contains only one variable, you can solve for x directly.
3x+4×(3/5)=2
Multiply 4 times 3/5
3x+12/5=2
Subtract 12/5 from both sides of the equation.
3x=-2/5
Divide both sides by 3.
x=-2/15
The system is now solved.
x=−2/15 ,y=3/5

Timberly spent 3 4/5 hours in Misty spent 2 1/10 hours at gymnastics practice over the weekend. How many more hours did Timberly spend than Misty at the gymnastics practice?
Answer:
Step-by-step explanation:
The common denominator of these 2 fractions is 10.
Turn the mixed number 3 4/5 into an improper fraction which would be
19/5.
Then multiply the numerator and denominator with 2 to get the denominator to be 10.
19/5 x 2 = 38/10
Now turn 2 1/10 into an improper fraction= 21/10
Now subtract...
38/10 - 21/10 = 17/10
So Timberly spent 17/10 or 1 7/10 more hours then Misty at the gymnastics practice

Brenda took one of her friends out to lunch. The lunches cost $70 and she paid 10% sales tax. If Brenda left a 10% tip on the $70, how much in total did she pay?
Answer: $84
Steps:
70 * 10%
70 * 0.10 = $7 sales tax
70 * 10%
70 * 0.10 = $7 tip
$70 lunch cost + $7 sales tax + $7 tip = $84

A ratio scale contains _____. the properties of order, classification, and equal distance between points but no unique origin the four major sources of error mutually exclusive and collectively exhaustive categories as well as the property of order, but not distance or unique origin the properties of classification, order, equal distance, and unique origin mutually exclusive and collectively exhaustive categories, but without the properties of order, distance, and origin
Answer:
the properties of classification, order, equal distance, and unique origin.
Step-by-step explanation:
A level of measurement refers to a classification which is used to illustrate the attributes of the values assigned to variables. Basically, there are four (4) levels of measurement for a variable and these are;
1. Ratio: data can be arranged in an ordering scheme and subtracting its differences is meaningful with respect to the value of true zero. Examples are height, price, weight, distance etc.
2. Nominal: is characterized by data that are non-numerical, comprises of categories, labels or names and can't be arranged in an ordering scheme.
3. Interval: data can be arranged in an ordering scheme and subtracting its differences is meaningful. Examples are year, temperature, time etc.
4. Ordinal: data can be arranged in an ordering scheme but subtracting its differences is meaningless or impossible. Examples are happy, sad etc.
Hence, a ratio scale contains the properties of classification, order, equal distance, and unique origin.

At 100°F, a certain Insect chirps at a rate of 97 times per minute, and at 102°F, they chirp 111 times per minute. Write an equation in slope-intercept form that represents the situation.
Answer:
y = 7x - 603
Step-by-step explanation:
We start by determining the slope:
m = y2 - y1/x2 - x1 = 111 - 97/102 - 100 = 14/2 = 7,
Now we substitute the slope into the slope-intercept equation y = mx + b, solving for the y-intercept [b]:
111 = 7(102) + b,
b = -603
Equation: y = 7x - 603

Find the perimeter of the figure to the nearest hundredth.
Answer:
42.84cm
Step-by-step explanation:
The perimeter is the sum of all the side length and the circumference of the semicircle
circumference of the semicircle = 2πr/2 = πr
circumference of the semicircle = 3.14 * (12/2)
circumference of the semicircle = 3.14 * 6
circumference of the semicircle = 18.84cm
Perimeter of the figure = 10cm + 6cm + 8cm + 18.84cm
Perimeter of the figure = 42.84cm (to nearest hundredth)
