Answer:

Step-by-step explanation:

a = -1

b = 2

c = 3

a + (-c) = -1 + (-3) = -4

Both numbers have same sign(-Ve).So add and the result will have the -Ve sign.

c - (-b) = c + b = 3 + 2 = 5

b = 2

Least to greatest: a +(-c) , b , c-(-b)

A cafe only sells two types of sandwiches, turkey and steak. The cafe charges $4 for turkey sandwiches and $6 for steak sandwich

Zolol [24]

$\left \{ {{T+S=925} \atop {4T+6S=4524}} \right. \\ S=925-T \\ 4T+6(925-T)=4524 \\ 4T+5550-6T=4524 \\ -2T+5550=4524 \\ -2T=-1026 \\ T=513$
So they sold 513 turkey sandwiches

Marlene rides her bicycle to her friend jon's house and returns home by the same route. marlene rides her bike at constant spee

riadik2000 [5.3K]

To solve the problem:

Let f = distance one way distance on level ground

Let h = distance rode on the hill

Write a time equation; where Time = distance/speed:

level time + uphill time + downhill time + level time = 1hr

f/9 + h/6 + h/18 + f/9 = 1 hr

Multiply equation by 18 to get rid of the denominators

2f + 3h + h + 2f = 18

4f + 4h = 18

Simplify by dividing this by 4

f + h = 4.5 miles is took her to get to Jon’s house.
