What is 1/3x -5/7 equal to

1 answer:

3 0

It can't be simplified because 1/3x and -5/7 aren't like terms and therefore you cannot do addition or subtraction with them.

If you meant x as in multiplied by then here is the solution:
1/3*-5/7
(1*-5)/(3*7)
-5/21

Hope this helps :)

Solve for x (30+x)+30+9x=360

UkoKoshka [18]

Answer:

x=30

Step-by-step explanation:

(30+x)+30+9x=360

We move all terms to the left:

(30+x)+30+9x-(360)=0

We add all the numbers together, and all the variables

(x+30)+9x+30-360=0

We add all the numbers together, and all the variables

9x+(x+30)-330=0

We get rid of parentheses

9x+x+30-330=0

We add all the numbers together, and all the variables

10x-300=0

We move all terms containing x to the left, all other terms to the right

10x=300

x=300/10

x=30

HELPP. Write the following as an algebraic expression. The sum of a and a quarter of b.

Fynjy0 [20]

Answer: $a + \frac{1}{4}b$

This is the same as $a + \frac{b}{4}$

All we're doing is adding 'a' and $\frac{1}{4}b$ since the term "sum" is the result of adding two or more numbers.

One quarter of a number is the same as dividing by 4.

Example: one quarter of 28 = $\frac{1}{4}*28 = \frac{28}{4} = 7$
