The equation: 6s - 10 = s
Add 10 to each side: 6s = s + 10
Subtract 's' from each side: 5s = 10
Divide each side by 5 : s = 2
Answer:
See Below
Step-by-step explanation:
If DF = 42, What is DE?
D__________E_______F
(7x + 1) + ( 4x-3) = 42
7x+1+ 4x -3 = 42 Solve for x
11x -2 = 42
+2 +2
11x = 44
11x / 11 = 44/ 11
x = 4
Now plug x in for the equation of DE
7x+1
7(4) + 1
28 + 1 = 29
DE = 19
Volume of pyramid = (L * W * H) / 3
(11 * 11 * 15) / 3 = 605cm^3
Answer:
no idea- I would say the answer is 4 but i don't know if the triangles are similar or not
Step-by-step explanation:
Answer:
The angles are supplementary
Step-by-step explanation:
Because of relationships between angles, the angles add up to 180°.
