Answer:
60 small and 140 large = 60 + 280 = 340 this is correct!
Step-by-step explanation:
I guess we just use the process of eleimation.
50 small and 150 Large = 50+300 = 350 so that's not right.
130 small and 70 large = 130 + 140 = 270 so, that's not right.
120 small and 80 large = 120 + 160 = 280 so, that's not right.
60 small and 140 large = 60 + 280 = 340 this is correct!

Answer:
If 4/8 cm = 25 miles
If 4.8 cm = 240 miles
If 48 cm = 2400
Step-by-step explanation:
4/8 x 50
4.8 x 50
48 x 50
I was unsure if there was a fraction bar or decimal. or if it was 48 so I gave all possibilities.

Answer:
Arc DE = 70°
Arc RST = 206°
Step-by-step explanation:
arc DE + arc DC = 180° because EC is a diameter
7x + 7 + 11x + 11 = 180°
combine like terms:
18x + 18 = 180°
subtract 18 from both sides of the equation:
18x = 162°
divide both sides by 18:
x = 9
Arc DE = 7(9) + 7 = 70°
arc RST = 2(x + 103) = 2x + 206
arc RFT = 2(x + 77) = 2x + 154
arc RST + arc RFT = 360°
so:
2x + 206 + 2x + 154 = 360°
combine like terms:
4x + 360 = 360
4x = 0
x = 0
arc RST = 2x + 206 = 206°
