Answer:
14
Step-by-step explanation:
(9x + 10)° = 136°
9x + 10 = 136
9x = 126
x = 14
Answer:
what expression???? is it Zn
Because of the Vertical Angles theorem, we know that the two expressions are equal.
6x - 35 = 4x + 11
Add 35 to both sides: 6x = 4x + 46
Subtract 4x from both sides: 2x = 46
Divide by 2 on both sides: x = 23
Now, insert x into one of the equations: 6(23) - 35
138 + 35
103
103 + K = 180
Subtract 103 from both sides: K = 77
K = 77
Answer:
it is 42069t
Step-by-step explanation:
To answer this question, you will find the number of kilometers she ran per hour. This is called the unit rate. To get the unit rate, you will divide the number of kilometers by the number of hours, so 25/3. The answer is 8 1/3 kilometers per hour. This number falls between the whole numbers 8 and 9. I will describe to you how to create a visual model to show this. If you draw a long bar and break it into 25 equal sections. Take 24 of these groups and circle 3 groups of 8 to show the 8 km. Take the last group and break it into 3 equal sections as well (creating groups the size of 1/3). One of these goes with the group of 8 you got when you broke the whole sections into groups of three creating the mixed number 8 1/3 kilometers. This shows you modeling the 25 km broken into 3 equal sized groups (which is division).
