how do I solve for x?
Answer:
85
Step-by-step explanation:
The sum of the measures of the interior angles of a triangle is 180 deg.
x + 52 + 43 = 180
x + 95 = 180
x = 85
Answer: 85
The angles in a triangle add up to 180 degrees
180 - 52 - 43 = 85
x = 85 degrees

A. X = 2
a
B. x= 2a
C. x =
За
D. X = 3a
[tex]x = \frac{2}{a} [/tex]
Step-by-step explanation:
3 ax + 4ax = 5ax + 4, combine like terms
7ax = 5ax + 4, minus 5ax from both sides
2ax = 4, divide 2a on both sides
you'll be left with x = 2/a

Name: /Event: /Time:
Tawni / 50-m Freestyle / 40.8
Pepta / 100-m Butterfly / 60.2
Susana / 200-m Medley / 112.4
Answer:
Susana
Step-by-step explanation:
divide the m by the time to get how many mps
50/40.8=1.225 mps
100/60.2=1.661 mps
200/112.4=1.779 mps
Write an equation of the line in standard form with integer coefficients. the line through (-2, 2), (1, -4). O A. y+2x=-2 B. y+2x=6 C. 2y+x=2 D. 2y+x=-6
Answer:
A
Step-by-step explanation:
K=(y1-y2)/(x1-x2)=(2+4)/(-2-1)=-2
y=-2x+b
2=-2*-2+b
b=-2
y=-2x-2
y+2x=-2
The equation of the line in standard form with integer coefficients is → y + 2x = - 2.
What is the general equation of straight line?The general equation of straight line is -
y = mx + c
where 'm' represents the slope of the line and 'c' is the y - intercept.
Given is a line that passes through the points -
(-2, 2), (1, -4)
We can calculate the slope of the line using the two coordinates given -
(-2, 2), (1, -4). The slope will be -
m = (- 4 - 2)/(1 + 2)
m = -6/3
m = - 2
Assume that the equation of line is -
y = -2x + c
The line passes through the point (-2, 2), so we can write -
2 = -2 x -2 + c
2 = 4 + c
c = -2
So, we can write the equation of line as -
y = - 2x - 2
or
y + 2x = - 2
Therefore, the equation of the line in standard form with integer coefficients is → y + 2x = - 2.

f(x) = -2x + 5
f ( ) = 13
Answer:
Okay, I haven't done this a long time however I believe with this you have to solve the equation by doing substitution.
Step-by-step explanation:
so, if f (x) equals 13, you replace the x in the equation to 13.
f(x)=-2x+5
f(x)=-2(13)+5
f(x)=26+5
f(x)=31
I believe 41 would be your answer. Hope this is right and it helped!

Find the 62nd term of the arithmetic sequence -27, -21, -15
The 62nd term of the arithmetic sequence -27, -21, -15 is 339
Arithmetic sequenceThe nth term of an arithmetic sequence is expressed as:
Tn =a+(n-1)d
Given the sequence -27, -21, -15
a is the first term = -27
d is the common difference = -21 + 27 = 6
n = 62
Substitute
T62 = -27 + (62-1)(6)
T62 = -27 + 61(6)
T62 = -27 + 366
T62 = 339
Hence the 62nd term of the arithmetic sequence -27, -21, -15 is 339

the percentage of boys in a school is 60%, and the number of girls are 200, calculate the number of boys and the total number of students?
Answer:
Boys: 300 or 60%, girls: 200 or 40%, total number of students: 500 or %100
Step-by-step explanation:
So basically:
1. We know that 60% is boys and we're trying to figure out the exact amount. We know the other 40% (girls) is a total of 200.
2. First take the 40% and half it so we get 20% in order to do that we have to do the same to the 200 girls and half the number into 100. Now we know 20% is equal to 100 students. Given that information we would multiply the 20% by 3 to get the 60% of boys. Now we would also multiply the 100 by 3 and now we have 300.
3. We now know that we have 300 boys and 200 girls. Add them together for the total of students and you get 500.
