Answer:
ernie=X so Daniel = X-6
Step-by-step explanation:
Ages of Dan and Cary are 29 and 33 respectively.
<u>Step-by-step explanation:</u>
Step 1:
Form equations out of the given details. Let the age of Dan be x, then age of Cary is x + 4.
In 7 years, sum of their ages = 76
⇒ (x + 7) + (x + 4 + 7) = 76
⇒ 2x + 18 = 76
⇒ 2x = 58
⇒ x = 29
Step 2:
Calculate age of Cary.
⇒ x + 4 = 33
So if it is 1/3 of 90 it would be 30 tiles. So you have to do 30 times the cost 2.69 which makes the cost the job 80.70
Answer:
x = 48 degrees
Step-by-step explanation:
This triangle is an isosceles which means that two of the angles are the same and all triangles add up to 180 degrees so we take the two angles we know and add them
66 + 66 = 132
Then we subtract that number from 180 to find the third angle
180 - 132 = 48
