Examine the system of equations. Which is an equivalent form of the first equation that when added to the second equation eliminates the y terms? Negative StartFraction 5 Over 8 EndFraction x + three-fourths y = 12 8 x + 12 y = 11
Answers
Answer:
10x - 12y = 192
Step-by-step explanation:
Given the equation :
-5/8x + 3/4y = 12 - - - (1)
8x + 12y = 11 ___(2)
The equivalent form of the first equation which can eliminate the y term :
Multiply (1) by - 16 :
-5/8x * - 16 + 3/4y * - 16 = 12 * - 16
10x - 12y = 192
Hence, Adding the obtained equation and equation(2) will eliminate.

A regular 13-gon is inscribed in a circle. Find the measure of each are intercepted by the sides of the polygon. Round your answer to the nearest hundreth of a degree.
Answers
Answer:
The measure of the angle subtended by each arc intercepted by the sides of the reh13-gon is approximately 27.69°
Step-by-step explanation:
The number of of equal sides in a regular 13-gon = 13 sides
The measure of the angle, 'θ', subtended by each arc intercepted by the sides of the 13-gon is given as follows;
θ = 360°/13 = [tex]27\dfrac{9}{13} ^{\circ}[/tex]
By rounding rounding the answer to the nearest 10th, we have that the measure of the angle subtended by each arc intercepted by the sides of the 13-gon, θ = [tex]27\dfrac{9}{13} ^{\circ}[/tex] ≈ 27.69°

Mark wants to round to the nearest hundred to estimate the sum of 271 and 582.
He wrote 270 + 580 = 850.
Part A
What mistake did Mark make?
A.
00:00
Mark should have rounded 271 to 250 and rounded 582 to 550: 250 + 550 = 800.
B.
00:00
Mark should have rounded 271 to 250 and rounded 582 to 600: 250 + 600 = 850.
C.
00:00
Mark should have rounded 271 to 300 and rounded 582 to 500: 300 + 500 = 800.
D.
00:00
Mark should have rounded 271 to 300 and rounded 582 to 600: 300 + 600 = 900.
00:00
Part B
What is the sum of 271 and 582 rounded to the nearest hundred?
A. 300
B. 850
C. 900
D. 1,000
Answers
Answer:
Step-by-step explanation:
Part A:
Mark did not round to the nearest hundreds, he rounded to the nearest tens.
Option A (Incorrect):
271 and 582 are normally not rounded down, unless we are using limits coming from the left and a unique equation.
Option B (Incorrect):
271 as the same problem as option A, but 582 rounding to 600 is correct. It doesn't make sense to round both numbers differently, unless stated.
Option C (Incorrect):
271 rounding to 300 is correct, but 582 is not normally rounded down to 500 unless we are using limits coming from the left and a unique equation. Unless stated, don't round both numbers differently.
Option D (Correct):
271 rounded to 300 and 582 rounded to 600 looks correct for rounding to the hundreds.
Part B:
There are two ways to solve this question:
One way:
271 + 582 = 853
Round 853 to the nearest hundred for 900
(Note: Round 853 to the nearest tens for 850.)
Second way:
271 + 582
Round Numbers:
300 + 600
= 900

Which ratio is smaller, 32 : 24 or 30 : 22?
Answers
Answer:
32 : 24 is smaller
Step-by-step explanation:
32 : 24 = 32/56, reduced is 4/7
30 : 22 = 30/52, reduced is 15/26
a common denominator is 182:
4/7 = 104/182
15/26 = 105/182
You need to get one number from each ratio to be equal
I’m gonna get 32 and 30 to equal
*first divide both ratios by 2(don’t have to do this just makes the no.’s smaller)
32:24
16:12
30:22
15:11
Multiply 16:12 by 15
And multiply 15:11 by 16
32:24 -> 16:12 -> 240:180
30:22 -> 15:11 -> 240:176
176<180
Therefore ratio 30:22 is smaller

Which linear function is graphed on the grid?
a - g(x) = 2/15x - 6
b - g(x) = 2/15x + 45
c - g(x) = 15/2x - 6
d - g(x) = 15/2x + 45
Answers
Answer:
G(x)=2/15x-6
Step-by-step explanation:
The linear function graphed on the grid will be g(x) = (15/2) x + 45. Then the correct option is D.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
x/a + y/b = 1
Where 'a' is the x-intercept of the line and ‘b’ is the y-intercept of the line.
From the graph, the x-intercept is - 6, and the y-intercept is 45. Then the equation is given as,
x/(-6) + y/45 = 1
- 15x + 2y = 90
y = (15/2) x + 45
g(x) = (15/2) x + 45
The linear function graphed on the grid will be g(x) = (15/2) x + 45. Then the correct option is D.
