Answer:

Step-by-step explanation:

Use the order of operations here to solve your expression.

First do Parentheses, then Exponents, Multiplication and Division, and Addition and Subtraction. An easy way to remember this is PEMDAS.

Let's dive right in,

$-3^{2}-7*-3+6\\-9-7*-3+6\\-9+21+6\\12+6\\18$

In conclusion, the value of this expression is 18. Hope this helped :D

Edit: fixed an error (did 3^2 instead of -3^2)

Answer: It's the first option

Step-by-step explanation: positive 2x because it is going up 2, 1 to the right (rise/run) and +5 because it touches the y-axis at 5. -2x because it's going down 2, 1 right (rise, in this case negative/run) and -2 because it touches the y-axis at -2.

On one side of a balancing scale there are 5 blocks: 3 weighing 3 grams each and 2 weighing x each. The scale is balanced if 8 b

natita [175]

Answer:

The weight of unknown block on each side of the scale is 1.5 grams.

Step-by-step explanation:

The number of blocks on 1 side = 5 blocks

Now, 3 blocks = 3 grams each

⇒Total weight of 3 blocks = (3 grams )times 3 = 9 grams

2 blocks = x grams each

⇒Total weight of 2 blocks = (x grams ) 2 = 2 x grams

So the total weight on 1 side = weight of 5 blocks combined

= 9 grams + 2x grams = (9 + 2x) grams

The total weight on other side of scale = 8 blocks times (x grams)

= (8x) grams

Now, The SCALE IS BALANCED if :

(9 + 2x) grams = (8x) grams

or, 9 + 2x = 8x

⇒9 = 8x - 2x = 6x

or, x = 9/6 = 1.5

⇒ x = 1.5 grams

Hence, the weight of unknown block on each side of the scale is

1.5 grams, so that the scale is balanced.
