Answer:
2/3 * 1/3 = 2/9
Step-by-step explanation:
You see the top 2 lines being shaded which is 2/3's of the whole square.
The second shaded part only covers 1/3 of the whole square.
Thus, you multiply both parts to figure out the darkest shaded part!
Answer:
x>=42
Step-by-step explanation:
multiply by 7 on both sides
Answer:
$0.65
Step-by-step explanation:
x=cost of washcloth
x+1.20=cost of towel
Now,
x+x+1.20=2.50
2x=1.30
x=0.65
So, cost of washcloth is $0.65
Instead of plugging in and right away, notice that
and now evaluating this expression at the two given values is easier, if only a little:
Answer:
Infinitely many solutions
Step-by-step explanation:
By multiplying the entire top equation by two, you'll find that both of these equations are actually technically the same, meaning that there are infinitely many solutions to this system.
