Combine likes terms to create an equivalent expression 1/7 - 3(3/7h -2/7)

Anastasy [175]

$\frac{1}{7} -3(\frac{3}{7}h -\frac{2}{7}) = \frac{7-9h}{7}$

Solution:

Given expression is:

$\frac{1}{7} -3(\frac{3}{7}h -\frac{2}{7})$

We have to combine the like terms

From given expression,

$\frac{1}{7} -3(\frac{3}{7}h -\frac{2}{7})$

By distributive property,

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

a(b + c) = ab + bc

Therefore,

Solve for brackets using distributive property

$\frac{1}{7} - (3 \times \frac{3}{7}h) + (3 \times \frac{2}{7})\\\\\frac{1}{7} - \frac{9h}{7} + \frac{6}{7}$

Add 1/7 and 6/7

$\frac{1}{7} + \frac{6}{7} -\frac{9h}{7}\\\\\frac{1+6}{7} -\frac{9h}{7}\\\\Simplify\\\\\frac{7}{7}-\frac{9h}{7}\\\\1-\frac{9h}{7}\\\\Simplify\\\\\frac{7-9h}{7}$

Thus the equivalent expression is found

Write the decimal as a fraction in simplest form. 0.25 (with 25 repeating)

zlopas [31]

1/4, because you disregard the repeating 25s and round, and 25 x 4 is one hundred, so simplified it's 1/4.

Write an expression to represent four more than the problem of three and a number z

kicyunya [14]

$Answer:$

If the "problem of 3 and a number $z$ " is multiplying: $4+(3z)$

If it's about adding: $4+(3+z)$

$Step-by-step$ $explanation:$

Scenario A: If it's 3 and z, then that means it's 3 $z$ , and we're adding 4, so it's $4+(3z)$ (make sure to put () around the 3 $z$ !)

Scenario B: If 3 and z is also 3+ $z$ , then the equation is $4+(3+z)$ (also use () on this too!)

Do 12 / 15 and 8 / 10 have the same value? Explain your answer.

yKpoI14uk [10]

Hello there!

12/15 and 8/10 don't have the same value.

Reason:
let's simplify both.

12/3 = 4

15/3 = 5

12/15 = 5/4

8/2 = 4

10/2 = 5

8/10 = 4/5

5/4 is greater than 4/5

5/4 > 4/5

Hope i helped!

Let me know if you need anything else!
