If m<6 = 7x -36 and m<9 = 5x + 12, what is the value of angle 11 ?
Answer:
Step-by-step explanation:
∠8 = ∠6
∠8 = 7x - 36
∠8 +∠9 = 180 {Linear pair}
7x - 36 + 5x + 12 = 180
7x + 5x - 36 + 12 = 180
12x - 24 = 180
12x = 180 + 24
12x = 204
x = 204/12
x = 17
∠6 = 7x - 36 = 7*17 - 36 = 119 - 36 = 83
∠11 = ∠6 {Vertically opposite angles}
∠11 = 83

you and your friend went shopping. you bought 3 shirts and 4 sweaters for $69. your friend bought 6 shirts and 2 sweaters for $66 how much does one shirt and one sweater coat each
I need this answered quickly
Answer:
Shirt = $7
Sweatshirt = $12
Step-by-step explanation:
Let T represent shirts and S to represent sweatshirts
you bought 3T + 4S = 69
your friend bought 6T + 2S = 66 multiply second equation by -2
-2 x 6T + 2S = 66
-12T - 4S = -132 now find the sum of this and first equation
3T + 4S -12T - 4S = 69 - 132 add like terms
-9T = -63 divide both sides by -9
T = 7 this is the cost of one shirt to find the cost of a sweatshirt we replace the T in any equation with 7
3T + 4S = 69
3*7 + 4S = 69
21 + 4S = 69 subtract 21 from both sides
4S = 48 divide both sides by 4
S = 12

Please tell me the answer up to e no.
(I think you need a-e, if not let me know and I will edit accordingly)
a: Divide both sides by 4
cm -> 12:8
3:2
b: Convert and divide both sides by 3
cm -> 150:9
50:3
c: Convert and divide both sides by 20
cm -> 100:80
5:4
d: Convert and divide both sides by 4
months -> 4:12
1:3
e: Convert and divide both sides by 250

Consider the system of equations.
5x + 2y = 12
5x – 2y = 28
What is the solution to the system of equations? Show work using substitution or elimination to support your answer.
A (4, -4)
B (-4, 4)
C (5, -6.5)
D (4, 16)
Answer:
A. (4, -4)
Step-by-step explanation:
Equation form x = 4, y = −4
Answer:
Option A
Step-by-step explanation:
5x + 2 y = 12 -----------(I)
5x - 2y = 28 ------------(II)
Add equation (I) & (II). So, y will be eliminated and we will get the value of x
(I) 5x + 2y = 12
(II) 5x -2y = 28 {Now add}
10x = 40
x = 40/10
x = 4
Plugin x = 4 in equation (I)
5*4 + 2y = 12
20 + 2y = 12
2y = 12 - 20
2y = -8
y = -8/2
y = -4
Which one of the following would prove that two triangles are congruenta
Answer:
Corroponding side lengths are equal
Step-by-step explanation:
Two triangles may have the same areas, but the sides might be different or in different spots than each other. The same goes for perimeter, therefore it doesn't mean that they are congruent. If two triangles had the same angle measures, it could still have any size side lengths. When corrosponding side lengths are equal, they have the same angles as well, so they are only congruent in this example.
Hope this helps :)
Find the x-intercept of the following equation. Simplify your answer
x − 7y = –10
x-intercept =
The x-intercept occurs when y = 0. Therefpre if we make y = 0, and solve for x, then we can find the x-intercept.
since x − 7(0) = –10
⇒ x − 0 = –10
x = -10
This makes the x-intercept of x − 7y = –10 (-10, 0).8.90 x 3.12 will give brainlist
27.768
Multiply 890 and 312
This equals 277680
We know that there were 4 numbers behind a decimal point
Therefore the last four numbers of 277680 need to be behind a decimal point as well
So you're answer is 27.7680 or 27.768
In the equation x + 10 = 22, what do you need to do to solve the problem ?
Answer:
In the given equation we need to find out the value of x to make this equation true.
First write the equationx+10 = 22Now place 10 to the other side[By placing 10 to the other side the symbol will change into -]x = 22-10Now subtract 10 from 22x = 12∴ 12 + 10 = 22PLEASE HELP what is the term what is A in the sequence and what is the common ratio

angle M and angle N are complementary. The measure of angle M is 38 degrees less than the measure of angle N Find the measure of each angle.
Answer:
M = 26 degrees, N = 64 degrees
Step-by-step explanation:
When 2 angles are complementary, it means they add up to 90 degrees. We can set up a system of equations to represent the situation.
M is measure of angle M
N is measure of angle N
M + N = 90 degrees
M = N - 38 (measure of angle M is 38 degrees less than measure of angle N)
We can then use the second equation to substitute in M in the first equation with N - 38
N - 38 + N = 90
2N - 38 = 90
2N = 128
N = 64 degrees
We plug this value back into the first equation to find M
M + 64 = 90
M = 26 degrees
The measure of ∠M and ∠N are 26° and 64° respectively.
What is a supplementary angle ?Supplementary angles sum to 180°.If two angles are supplementary their sum is 180° and sum of two complementary angles is 90°.
According to the given question angle M and angle N are complementary.
∴ Sum of these two angles ∠M + ∠N = 90°.
Assuming measure of ∠N to be x°,So the measure of ∠M is (x-38)°.
Therefore, x + (x-38) = 90°.
2x = 90° + 38°
2x = 128°.
x = 64°.
∴ The measure of ∠M is (64 - 38 )° = 26°.
