Answer:
Equation: 3x-20+x=180
4x-20=180
4x=200
x=50
Step-by-step explanation:
If you are asking how many hot dogs and cans of soda are sold, this is how I solved it.
Given:
cost of hot dog $3
cost of a can of soda $1
total items sold: 350
total sales: $624
let h stand for hot dog and s stand for soda.
h + s = 350
3h + 1s = 624
h = 350 - s
3(350-s) + s = 624
1,050 -3s + s = 624
-2s = 624 - 1050
-2s = -426
-2s/-2 = -426/-2
s = 213 cans of soda
h = 350 - s
h = 350 - 213
h = 137 hot dogs
3h + s = 624
3(137) + 213 = 624
411 + 213 = 624
624 = 624
Mitchell sold 137 hot dogs and 213 cans of soda.
Answer:
≈ 11.78 in
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
= 2πr × 
( cancel 2π on numerator/ denominator )
= 15 × 
= 
≈ 11.78 in ( to 2 dec. places )
Answer:
Identity property
Step-by-step explanation:
Identity property of multiplication: The product of 1 and any number is that number. For example, 7 × 1 = 7 7 \times 1 = 7 7×1=77, times, 1, equals, 7.
