Answer:

The number of fries and shakes sold are 70 and 35 respectively.

Step-by-step explanation:

The number of fries sold can be denoted by <em>x</em>.

The number of shakes sold can be denoted by <em>y</em>.

The equation representing the total number of items sold is:

<em>x</em> + <em>y</em> = 105...(i)

The cost fries is, $2.

The cost of shakes is, $3.

The equation representing the total money earned is:

2<em>x</em> + 3<em>y</em> = 245...(ii)

Solve equations (i) and (ii) simultaneously as follows:

Multiply equation (i) by 3 and subtract:

3x + 3y = 315

2x + 3y = 245

(-)     (-)      (-)

___________

x = 70

Compute the value of <em>y</em> as follows:

x + y = 105

70 + y = 105

y = 105 - 70

y = 35

Thus, the number of fries and shakes sold are 70 and 35 respectively.

Lila flies a drone in the direction of 90° towards Avery. Once she gets to Avery she changes course and flies in the direction o
Nikitich [7]

Answer:

X = 13.13 feet

Step-by-step explanation:

Let the distance between Lila and Mark be x.

Let the distance between Avery and lila be A= 20

Let the distance between Avery and Mark be B= 30

Angle x = 200-180=20°

To solve this question we will use the cosine formula which is

X² = A²+ B² -2ABcosx

X²= 20² + 30² -2(20)(30)cos20

X²=1300-1127.6

X²= 172.4

X= 13.13

River C is 200 miles longer than River D. If the sum of their lengths is 5580 ​miles, what is the length of each​ river?
Valentin [98]

Yo sup??

Let the length of river D be x

then the lenght of river C will be 200+x

but,

lenght of river C+lenght of river D=5580

x+x+200=5580

2x=5380

x=2690

Therefore lenght of river D is 2690 and that of C is 2890

Hope this helps
