These angles, 110º and 7xº, are examples of supplementary angles.
Supplementary angles are angles that, when added together, produce a sum of 180º.
This means 110º + 7xº = 180º.

With this equation, 110º + 7xº = 180º, we can isolate the variable and solve for x to answer this question.

110º + 7xº = 180º
The first step to solve for x is to subtract 110º from both sides of the equation.
110º + 7xº - 110º = 7xº
180º - 110º = 70º

7xº = 70º
Since we want 1xº instead of 7xº, we need to divide both sides by 7.
7xº / 7 = xº
70º / 7 = 10º

xº = 10º
Now we have our solution!
The value of x is 10º.

Let's check this to be sure.
7xº, when added to 110º, must equal 180º since 7xº and 110º are supplementary angles.
7xº + 110º = 180º
We found that x is 10º.
7(10)º + 110º = 180º
7 • 10 = 70
70º + 110º = 180º
180º = 180º
This works! That means that x = 10º is in fact the correct answer.

Answer:
x = 10º

Hope this helps!

otez555 [7]

Answer:

a)6x = 16

Step-by-step explanation:

<h2><u>Finding the value</u></h2>

the ratio can be solved by <u>cross multiplication :</u>

6       :          2

8       :          x

6*x = 8*2

6x = 16

answer is : <u>a) 6x = 16</u>

Answer: 15 + 53/77


Step-by-step explanation:


Multiplying a fraction by 1 does not change the value.

Any number divided by itself is 1.

For instance, 11/11 = 7/7 = 1.


12 + 1/7 + 3 + 6/11 = 15 + 1/7 + 6/11

= 15 + (11×1)/(11×7) + (7×6)/(7×11)

= 15 + 11/77 + (6×7)/77

= 15 + (11 + 6×7)/77

= 15 + 53/77


It is faster to make sure to multiply by the "smallest" form of one that will work, but you don't have to. You only need to make sure that at the end there are no common factors in numerator and denominator, and that numerator is smaller than denominator.

I WILL GIVE BRAINLIEST AND 10 POINTS IF ANSWERED QUICKLY!!!!!!!!!!!!!
vladimir1956 [14]

Answer: A=100(12)t5.27


Step-by-step explanation:

Assume / and ^ got lost from eqns.

A(t) = initial × (1/2)^(t/halflife)

So initial = 100, halflife = 5.27,

A=100(12)t5.27 means A=100(1/2)^(t/5.27)

so that A is 50 when t is 5.27
