Each triangle has a sum of angles that equal 180° so set each angle measure = 180
(x + 66) + (x + 86) + 50 = 180; add accordingly
2x + 202 = 180; subtract 202 from both sides
2x = -22; divide both sides by 2
x = -11
Plug in -11 for x to check
(-11 + 66) + (-11 + 86) + 50 = 180
55 + 75 + 50 = 180
180 = 180 so -11 is the correct value of x
Answer:
The cost of 6 cans of soup = $7.8
Step-by-step explanation:
The cost of 10 cans of soup = $13
The number of cans needed for the soup = 6
Now, Cost of 1 can of soup =
= $13 / 10 =$1.3
⇒The cost of 1 can of soup is $1.3
Now, The cost of 6 cans of soup = 6 x Cost of 1 can
⇒ 6 x $1.3 = $7.8
Hence, the cost of 6 cans of soup = $7.8
Answer:
70
Step-by-step explanation:
840 / 12 = 70
Answer:
200 mL
Step-by-step explanation:
If x is the volume of solution B:
0.06 (500) + 0.20 x = 0.10 (500 + x)
30 + 0.20 x = 50 + 0.10 x
0.10 x = 20
x = 200
