Answer:
girllll
Step-by-step explanation:
Because a triangle is 180 degrees, and you already have a right angle that leaves 90 degrees for the rest of the angles.
So, (2x) + (x+15) = 90
Combine like terms.
3x + 15 = 90
Subtract 15 from 90.
3x = 75
Divide.
75/3, so x = 25.
To solve this we would need to make two equations. One equation accounts for the number of hot dogs and sandwiches and the other is the total cost
X + Y = 985
2.95x + 9.95y = 7343.75
Solve for one variable and plug it into the other equation. And solve for the next variable.
X = hotdogs
Y = sandwiches.
To find the decimal form, you have to manually divide 1 by 8. Since 8 is greater than 1, the quotient would then start with 0., then you add a 0 next to 1, to make it 10. This time, divide 10 by 8. The nearest answer would be 1, because 1 *8 = 8. Subtracting this from 10, you get 2. Add another 0 to 2, to make it 20. Do the cycle all over again. The complete solution is as follows:
0.125
---------------------------
8 | 10
- 8
------------------------
20

<em>Hence, the decimal form of 1/8 is 0.125.</em>
6+4x. You multiply two times three and then multiply two times 2X
