3 + 9x = 11x - 7
Answer:
3 + 9x = 11x - 7
simplify
9x + 3 = 11x - 7
subtract 11x from both sides
-11x -11x
-2x + 3 = -7
get rid of constants first by subtracting by 3 from both sides
-3 -3
-2x = -10
divide both sides by -2 since that is the inverse operation of multiplication
/-2 /-2
X = 5
Answer:
x=5
Step-by-step explanation:
Hi, first the thing to do here is simple,
step 1, collecting like terms
3+9x=11x-7
11x-9x=3+7
2x=10
then divide both by 2.
x= 5

the sum of two opposite angles of a parallelogram is 140 degree . find all the angles ofa parallelogram?
Answer:
since opp. angles of a parallelogram is equal.
therefore,
let the angle be x
thus,
x+x=140
2x=140
x=70°
co interior angles are supplimentary,
thus,
x+y=180
y=180-70
y=110°
opp. angles are equal thus,
fourth angle =110°
1st angle=70
2nd angle=70

75. is yr correct ans.
Step-by-step explanation:

stay safe healthy and happy.
Answer:
x = 75
Step-by-step explanation:
The triangle has 2 congruent sides and is therefore isosceles with 2 congruent base angles, both of measure x
The sum of the 3 angles = 180° , that is
x + x + 30 = 180
2x + 30 = 180 ( subtract 30 from both sides )
2x = 150 ( divide both sides by 2 )
x = 75

3n+8 = 5n-10
-8 -8
3n = 5n-18
-5n -5n

need help multie choice
the answer is a the same line
Answer:
A - The same line
Step-by-step explanation:
First, let's simplify 6x - 15y = 15:
Add 15y to both sides to get 15 + 15y = 6x, and then subtract 15 on both sides to get 15y = 6x - 15. We can then divide by 15 on both sides to get y = 6x/15 - 1, which can be simplified to (since 6/15 = 2/5):
y = 2x/5 - 1
y = 2x/5 - 1 is the same as the second bullet point, and since the equations of the lines are the same, this means that the lines are the same. Therefore, the answer is A - The same line.
Prove how they are congruent. Geometry:SSS

For the given triangles to be congruent by SSS criterion, the sides HJ and LN should be equal ~
therefore correct choice is ~ C

The additional information needed to prove that both triangles are congruent by the SSS Congruence Theorem would be: C. HJ ≅ LN
Recall:
Based on the Side-Side-Side Congruence Theorem, (SSS), two triangles can be said to be congruent to each other if they have three pairs of congruent sides.Thus, in the two triangles given, the two triangles has:
Two pairs of congruent sides - HI ≅ ML and IJ ≅ MNTherefore, an additional information needed to prove that both triangles are congruent by the SSS Congruence Theorem would be: C. HJ ≅ LN

n a class of 40 students, 15% of the students were absent on a particular day.
How many students were absent on that day?
Answer:
6
Step-by-step explanation:
15% of 40 is 6.
So 6 was absent.
Out of 40 students total 6 students were absent on the particular day.
What is percentage?Percentage is a measurement to find value of given number out of hundred.
Given that,
Total number of students in a class = 40.
Also, 15% of the total students were absent on a fixed day.
To find the number of students who were absent,
Use percentage property,
Absent students = 40 x 15%
= 40 x 15/ 100
= 600 / 100
= 6

if x and y are positive numbers xy = 96 what is the value of x
The value of x is 96/y where y is not equal to zero.
Given the expression that relates x and y as xy = 96
We are told that x and y are positive numbers. To get the value of x, we will divide both sides by y as shown:
[tex]xy = 96\\\frac{xy}{y} =\frac{96}{y} \\x = \frac{96}{y} \\[/tex]
From the result, we can conclude that the value of x is 96/y where y is not equal to zero.

Answer:
B. II only . . . (-1, 4)
Step-by-step explanation:
The function factors as ...
f(x) = (x +1)(x -4)
The factors are zero when x=-1 and x=4. The value of the function will be negative when one of these factors is negative, between x=-1 and x=4. In interval notation, that interval is ...
