Which is an equation in point-slope form for the given point and slope?Point: (1, –7); Slope: -2/3

Answer:

x=40 and y= 60

Step-by-step explanation:

step:1

Let 'x' and 'y' are two numbers

given data the sum of two numbers is 100

x+y = 100......(1)

Given difference of two numbers are

x - y = -20 ......(2)

Step :2

solving the equation (1) and (2)

adding the equations (1) and (2)

x+y+x-y=100-20

cancelling 'y' terms are

2 x = 80

dividing "2" on both sides, we get

x = 40

Step :3

substitute x = 40 in equation (1)

x + y =100

40 + y = 100

subtracting "40" on both sides, we get

40 + y - 40 = 100 -40

y = 60

Final answer:-

The two numbers are x = 40 and y= 60

The solution is,  to the equation 7z = 56 is, z = 8.

What is division?

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

given that,

the equation 7z = 56

now, we have to solve this to get the value of z.

so, we have,

7z = 56

now, dividing both side by 7, we get,

7z/7 = 56/7

or, z = 56/7

or, z = 8

Hence, The solution is,  to the equation 7z = 56 is, z = 8.
