The equation x + y = z relates the whole numbers x, y, and z. How does z compare to x? Y is z less than x. Y is z more than x. X

rewona [7]

Answer:

x is y less than z

Step-by-step explanation:

The given equation is x + y = z

This equation relates the whole numbers x, y, and z.

This equation can be rearranged to make x the subject of the formula or to make y the subject of the formula. When this is done, the relationship between the terms or numbers would be clearly expressed.

Making y the subject of the formula, it becomes

y = z-x (this shows that z is greater than y by x)

Making x the subject of the formula, it becomes

x = z-y (this shows that z is greater than x by y)

Looking at the options given, the correct comparisons between z and x is

x is y less than z

In a two-digit number the tens digit is four less than the units digit. Seven times the tens digit plus five times the units dig

Iteru [2.4K]

The digits of the number are 7 and 3

Step-by-step explanation:

In a two-digit number:

The tens digit is four less than the units digit

Seven times the tens digit plus five times the units digit is equal to 56

We need to find the digits

Assume that the unit digit is x and the ten digit is y

∵ x represents the unit digit

∵ y represents the ten digit

∵ The ten digit is four less than the unit digit

- That means subtract 4 from the unit digit to get the ten digit

∴ y = x - 4 ⇒ (1)

∵ Seven times the tens digit plus five times the units digit is

equal to 56

- That means multiply the ten digit by 7 and the unit digit by

5 and add the two products and equate the sum by 56

∴ 7y + 5x = 56 ⇒ (2)

Now we have a system of equations to solve it

Substitute y in equation (2) by equation (1)

∵ 7(x - 4) + 5x = 56

- Simplify the left hand side

∴ 7x - 28 + 5x = 56

- Add the like terms in the left hand side

∴ 12x - 28 = 56

- Add 28 to both sides

∴ 12x = 84

- Divide both sides by 12

∴ x = 7

- Substitute the value of x in equation (1) to find y

∵ y = 7 - 4

∴ y = 3

∴ The number is 37

The digits of the number are 7 and 3
