Answer: 2.339
Step-by-step explanation:
Make sure that you align your decimal points. The 1 shouldn't line up with the 7.
Instead, write your equation like:
2.37
- 0.031
The numbers don't match up, but instead, the decimals do.

Lukas graphed the system of equations shown.
2x + 3y = 2
y = A system of equations. 2 x plus 3 y equals 2. y equals StartFraction one-half EndFraction x plus 3.x + 3
A coordinate grid with 2 lines. The first line passes through the points labeled (negative 2, 2), (0, 0.67) and (1, 0). The second line passes through the points labeled (negative 2, 2) and (0, 3).
What is the solution to the system of equations?
The solution to the system of equations is A. (-2, 2)
How to calculate the value?The system of equation was:
2x + 3y = 2 ..... i
y = 1/2x + 3 ...... ii
Substitute equation ii into i
2x + 3/2x + 9 = 2
Multiply through by 2.
7x + 18 = 4
7x = -14
Divide
x = 14/7
x = -2
Also, y = 1/2x + 3
y = 1/2(-2) + 3
y = -1 + 3
y = 2
Therefore, the solution to the system of equations is (-2, 2).

For their history project, students case to either write a report or give a presentation. Two fifth of the students wrote a report and 0.6 of the students gave a presentation. Dominic said that more students gave a presentation. Do you agree with Dominic? Use numbers and words to support your answer. *
Answer: Yes. Dominic is correct
Step-by-step explanation:
We are informed that Two fifth of the students wrote a report. This also means that (2/5 × 100) = 40% = 0.4 wrote a report and 0.6 of the students gave a presentation.
From the decimals gotten, we can see that 0.6 is more than 0.4. Therefore, more students gave a presentation. This implies that Dominic is correct.
In the diagram below, AB is parallel to CD. What is the value of x?
A. 120
В. 80
с. 100
D. 60
Answer:
120
Step-by-step explanation:
By the rule of opposite angles, we can determine that x=120 because:
AB is parallel to CD
120 degree angle (let's call it Y) is on AB
X (we can see that it is obtuse) is on CD
So, Y is congruent to X, vice versa, so x=120

(a) Work out the value of (16/81)^3/4
Answer: 8/27
Step-by-step explanation:
Just evaluate the equation.
Do it in this order: Parenthesis, Exponents, Multiply/Divide, Add/Subtract.
So:
16/81 = 16/81
16/81 To the Power of 3/4 = 0.2^0.75 = 8/27

Will the standard form of 8.5 × 10–3 be more or less than 1? Explain what effect the negative exponent has.
The value is less than 1 and the impact of the negative exponent is that it moves the decimal point to the left
What is standard form?Standard form can be defined as a mathematical way of writing large or too small numbers in a defined manner.
Given the standard form;
8.5 × 10–3
The negative exponent (-3) indicates an addition of three zeros ruled out from the start.
It could be written as;
0. 0085
This is 0. 9915 less than the value of 1
The impact of the negative value is that it moves the decimal point to the left.
Thus, the value is less than 1 and the impact of the negative exponent is that it moves the decimal point to the left

Which of these is an example of typing at a rate of 42 words per minute?
A
typing 21 words in 2 minutes
B

С
typing 210 words in 5 minutes
D
typing 400 words in 10 minutes
Answer:
C. typing 210 words in 5 minutes
Step-by-step explanation:
Because 210 divided by 5 equals 42 over 1. :)
Answer:
C. Typing 210 words in 5 minutes
Step-by-step explanation:
42 words per minute, so think about this. 42 plus 42 is 84, so it is not A cause a to less than 84. And it is not Ba either cause 84 words is 2 minutes. 42×5=210

9514 1404 393
Answer:
(13.06, 16.41)
Step-by-step explanation:
Any point not on a perpendicular bisector of the line between towns will be closer to one town than the other. So, the intersection of perpendicular bisectors will be the equidistant from all towns. That point is the circumcenter of the circle circumscribing the triangle with the towns as its vertices. This can be found as the intersection of two perpendicular bisectors of the segments between the towns.
The midpoint of AB is ...
(A +B)/2 = ((15, 3) +(25, 10))/2 = (40, 13)/2 = (20, 6.5)
The midpoint of AC is ...
(A +C)/2 = ((15, 3) +(0, 20))/2 = (15, 23)/2 = (7.5, 11.5)
__
The differences between points are ...
B -A = (25, 10) -(15, 3) = (10, 7)
C -A = (0, 20) -(15, 3) = (-15, 17)
Then the perpendicular bisector equations can be written as ...
bisector of AB ⇒ 10(x -20) +7(y -6.5) = 0
10x +7x -245.5 = 0
bisector of AC ⇒ -15(x -7.5) +17(y -11.5) = 0
-15x +17y -83 = 0
These have coefficients that aren't particularly nice, so a method similar to Cramer's Rule is suitable for solving this pair of equations. Using the "cross multiplication method", we have ...
x = (7(-83) -17(-245.5))/(10(17) -(-15)(7)) = 3592.5/275 = 13 7/110 ≈ 13.06
y = (-245.5(-15) -(-83)(10))/275 = 4512.5/275 = 16 9/22 ≈ 16.41
The point as far as possible from each town within the boundary of the island has coordinates (13.06, 16.41).
_____
Further detail regarding the solution
Here, we have written the equation for the perpendicular bisector this way. The difference in coordinates between points R and S can be called ...
R -S = (∆x, ∆y)
The midpoint of segment RS can be called ...
(R +S)/2 = (h, k)
Then the line that is a perpendicular bisector of RS can be written as ...
∆x(x -h) +∆y(y -k) = 0
This is the form that is used above.
__
The "cross multiplication method" for solving a pair of general-form linear equations ...

Solve for x in the triangle above
Answer:
x = 30
Step-by-step explanation:
The interior angles of a triangle must always add up to 180.
2x + 2x + 3x - 30 = 180
Add 30 to both sides to seperate variables.
2x + 2x + 3x = 210
Combine like terms.
7x = 210
Divide by 7 to isolate x.
x = 30
