Is the given value a solution to the equation? 4(n) - 3 = -2(n) + 9 n=2
Answer:
Yes!
The solution to the equation is n = 2
Step-by-step explanation:
Given the equation
[tex]4\left(n\right)-3=-2\left(n\right)+9[/tex]
remove the parentheses
[tex]4n-3=-2n+9[/tex]
Add 3 to both sides
[tex]4n-3+3=-2n+9+3[/tex]
Simplify
[tex]4n=-2n+12[/tex]
Add 2n to both sides
[tex]4n+2n=-2n+12+2n[/tex]
Simplify
[tex]6n=12[/tex]
Divide both sides by 6
[tex]\frac{6n}{6}=\frac{12}{6}[/tex]
Simplify
[tex]n=2[/tex]
Therefore, the value of n = 2.
Hence,
Yes!
The solution to the equation is n = 2

ASAP. Triangle ABC has angle measures as shown. complete sentences
(a) What is the value of x? Complete sentence. Show your work.
(b) What is the measure of each angle? Do the 3 angles add to 180 degrees? Show your work
In a triangle, the three angles ALWAYS add up to 180°
x + (6x + 10) + (x + 2) = 180
8x + 12 = 180
8x = 168
x = 21
To calculate the measure of each angle, substitute x in:
Angle A: 21
Angle B: 6(21)+10
Angle C: 21 + 2
Do the angles add up to 180 degrees? Just add the answer for A B and C and see if the sum is 180. It should be 180, if it isn't something is wrong with the calculation.

I have to find slope-intercept equation
Answer:
y = 4x - 9
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
the y-intercept is when the line crosses the y axis, and in this case we can see it at "-9"
The slope we can do rise over run "r/r" ot "y/x"
r/r = 4/1 = 4
The line is positive since its going up
y = 4x - 9

PLS HELP. this is due soon,
only answer if you actually know it; no guessing for points please
Answer:
102
Step-by-step explanation:
x = 180 - (4x - 2) - 78
x = 180 - 4x + 2 -78
5x = 180 + 2 - 78
5x = 104
x = [tex]20\frac{4}{5}[/tex].
So, angle UTW is 4 * [tex]20\frac{4}{5}[/tex] - 2 + [tex]20\frac{4}{5}[/tex] = 5 * [tex]20\frac{4}{5}[/tex] - 2 = 104 - 2 = 102

Richard gets a bonus of 30% of £130 Connor gets a bonus of £40 work out the difference between the bonus Richard gets and the bonus Connor gets
Answer:
Please check the explanation.
Step-by-step explanation:
Given that Richard gets a bonus of 30% of £130.
Thus,
Richard's bonus = 30% of 130
= 30/100 × 130
= 39
Thus, Richard gets £39.
Given that Connor gets a bonus of £40.
The difference between the bonus Richard gets and the bonus Connor gets.
Difference = Connor Bonus - Richard Bonus
= £40 - £39
= £1
It means Connor gets £1 more than what Richard gets.
Therefore, the difference is: £1

5 hours after noon, darmian is 17 miles closer to the stadium than paisley
Step-by-step explanation:
At noon, Damian is 383 miles away from the stadium and paisley is 315 miles away from the stadium.
Now, we are told that damians speed is 59 mph while paisley's speed is 42 mph.
At t hours after noon, their distance covered will be;
Damian; D = 59t
Paisley; P = 42t
This is because distance = speed × time
Now, 5 hours after noon, their respective distance covered will be;
D(5) = 59 × 5 = 295 miles
P(5) = 42 × 5 = 210 miles
This means that;
distance of Damian from the stadium is; 383 - 295 = 88 miles
Distance of paisley from the stadium is;
315 - 210 = 105 miles
Difference in their distances to the stadium = 105 - 88 = 17 miles
Thus, 5 hours after noon, darmian is 17 miles closer to the stadium than paisley

what is 153.87 divided by 23
The result of dividing 153.87 by 23 is approximately 6.6847826087.
Given that we need to determine that what is 153.87 divided by 23,
To justify this answer, we can perform the division calculation:
6.6847826087
--------------
23 | 153.87
138
-----
158
138
-----
208
207
-----
10
The division is performed by dividing 23 into 153.87. We start by dividing 23 into 153, which gives us 6 as the whole number part of the quotient. We then subtract 138 (6 multiplied by 23) from 153, which leaves us with a remainder of 15.
To obtain a decimal approximation, we bring down the decimal point from the dividend (153.87) and continue the division process.
We add a zero after the decimal point in the dividend and divide again. This time, 23 goes into 158 (the new dividend) 6 times, giving us a partial quotient of 0.6.
The remainder is 158 minus 138 (6 multiplied by 23), which equals 20.
We bring down another zero and continue dividing.
23 goes into 208 (the new dividend) 9 times, resulting in a partial quotient of 0.69. The remainder is 208 minus 207 (9 multiplied by 23), which equals 1.
At this point, we can either stop or continue dividing to obtain more decimal places.
Therefore, the result of dividing 153.87 by 23 is approximately 6.6847826087.

What does it mean for a point to be a solution to a linear equation?
For example, if I say, "(2,5) is a solution to the equation (y=2x+3)," how could you check my claim?
Answer:
In your equation y=2x+3 and you used 2 [from your point (2,5) ] as the value of x, then y=2(2)+3=7.
now if you plotted this, that point would be (2,7), not (2,5).
So (2,5) is not the solution.
(2, 5) is not a solution of the linear equation [tex]y = 2\cdot x + 3[/tex].
Let be linear equation [tex]y = 2\cdot x + 3[/tex], if we know that [tex](x,y) = (2, 5)[/tex] and we need to check is [tex]2\cdot x + 3 = 5[/tex] by algebraic means, that is, we solve for [tex]x[/tex]:
[tex]2\cdot x + 3 = 5[/tex]
[tex]2\cdot x = 2[/tex]
[tex]x = 1[/tex]
Hence, we conclude that (2, 5) is not a solution of the linear equation [tex]y = 2\cdot x + 3[/tex].
