Answer:
Step-by-step explanation:
v+2.5c=191.5 and c+v=103, so c=103-v, using this c in first equation gives you
v+2.5(103-v)=191.5
v+257.5-2.5v=191.5
-1.5v=-66
v=44
So 44 vegetarian wraps were sold.

Answer:
y=-12/5x+62
Step-by-step explanation:
to solve this i turned two point form, 5,50 and 17 1/2,20, into slope intercept form by using the formula y-y1=(y2-y1/x2-x1)(x-x1), which when input with the data becomes y-50=(20-50/17 1/2-5)(x-5) which then becomes y-50=-12/5(x-5), then y-50=-12/5x+12, and finally y=-12/5x+62
Answer: try √265
Step-by-step explanation:
Answer:
A = 25π cm²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( where r is the radius )
Here diameter = 10, thus r = 10 ÷ 2 = 5, then
A = π × 5² = 25π cm²
