Answer:
3 tenths
Step-by-step explanation:
One candy bar
= 1 candy bar
= 1.0, or 10 tenths (one tenth is 0.1)
If Theo eats 0.7 of a candy bar, we know that
1.0 - 0.7 = 0.3
0.3 = 3 *0.1 (one tenth)
Therefore, the answer is 3 tenths.
-3x + 3 < 6 <em>subtract 3 from both sides</em>
-3x < 3 <em>change the signs</em>
3x > -3 <em>divide both sides by 3</em>
<h2>x > -1</h2>
It would be C because you don’t know how many watches so there is a variable, x. Then the price has to be less then or equal to because the amount is the most she can use so it can’t be greater.
Given ,
To find ,
value of x
Now ,
Dividing both sides by 2 , we get
nikal -,- xD
