He sold 32 small watermelons and 17 large watermelons.

Step-by-step explanation:

Let,

Small watermelons = x

Large watermelons = y

Cost of one small watermelon = $7

Cost of one large watermelon = $10

According to given statement;

x = y+15   Eqn 1

7x+10y=394   Eqn 2

Putting value of x from Eqn 1 in Eqn 2

7(y+15)+10y=394\\7y+105+10y=394\\17y=394-105\\17y=289\\

Dividing both sides by 17

\frac{17y}{17}=\frac{289}{17}\\y=17

Putting y=17 in Eqn 1

x=17+15\\x=32

He sold 32 small watermelons and 17 large watermelons.

goldfiish [28.3K]

Answer:

Yes any number can be substituted for h

Step-by-step explanation:

The term 'h' is an independent variable any number can be substituted for h, so long as the number represents the hours worked

So if she walks pets for 8 hours

Her pay is 4*8= $32

1. From the statement select the related given statement.
solong [7]

1. Line l; point P not on l.( Take a line I and mark point P outside it or on the line.So from point P there are infinite number of lines out of which only one line is parallel to line I. Suppose you are taking point P on line I, from that point P also infinite number of lines can be drawn but only one line will be coincident or parallel to line I.

2. Plane R is parallel to plane S; Plane T cuts planes R and S.(Imagine you are sitting inside a room ,consider two walls opposite to each other as two planes R and S and floor on which you are sitting as third plane T ,so R and S are parallel and plane T is cutting them so in this case their lines of intersect .But this is not possible in each and every case, suppose R and S planes are parallel to each other and Plane T cuts them like two faces of a building and third plane T is stairs or suppose it is in slanting position i.e not parallel to R and S so in this case also lines of intersection  will be parallel.

3. △ABC with midpoints M and N.( As you know if we take a triangle ABC ,the mid points of sides AB and AC being M and N, so the line joining the mid point of two sides of a triangle is parallel to third side and is half of it.

4.Point B is between points A and C.( Take a line segment AC. Mark any point B anywhere on the line segment AC. Three possibilities arises

(i) AB > BC (ii) AB < BC  (iii) AB = BC

Since A, B,C are collinear .So in each case  AB + BC =AC

Solve this system of equations
olga_2 [115]

Answer:

D) x = 4, y = -2, z = 3

Step-by-step explanation:

x = 3z − 5

2x + 2z = y + 16

2(3z - 5) + 2z = y + 16

6z - 10 + 2z = y + 16

8z = y + 26 ---> (A)

7x − 5z = 3y + 19

7(3z - 5) - 5z = 3y + 19

21z - 35 - 5z = 3y + 19

16z = 3y + 54 ---> (B)

8z = y + 26

16z = 3y + 54

2(y + 26) = 3y + 54

2y + 52 = 3y + 54

y = -2

8z = -2 + 26

8z = 24

z = 3

x = 3(3) - 5

x = 4

Find the lateral area and the total area of the prism.
Tems11 [23]
We have that

1) the lateral area---------------->  L=P*h
P=(3+3+3)   h=6
L=(3+3+3)*6=54 in²

the answer part 1) is the lateral area is 54 in²

2) the total area=------------- > S=P*h+2B
2B=2*[3*3/2]     P*h=54

S=2*[3*3/2]+54=63 in²

the answer part 2) is the total area is 63 in²
