Answer:
Step-by-step explanation:
Step 1: Sum of angles on a straight line is 180
Step 2:
2x + 25 + y = 180
2x + y = 180 - 25
2x + y = 155 (1)
Step 3:
3x - 10 + y = 180
3x + y = 180 + 10
3x + y = 190 (2)
Step 4: Substract equation 1 from 2
3x + y - 2x - y = 190 - 155
x = 35
Step 5:
Substitute x in equation 1 to find y
2x + y = 55
2(35) + y = 155
70 + y = 155
y = 155 - 70
y = 85

Answer:
100/275=x/37
Step-by-step explanation:
37 heads for 100 guests that means the ratio is 37/100
To calculate how many is needed for 275 guests we should to multiply 275 by 37 and divide it by 100
And the expression for it is 100/275 = x/37
