Answer:
10 cm
Step-by-step explanation:
1 decimeter is equal to 10⁻¹ meters.
1 meter is equal to 10² centimeters. We can use a conversion fraction to find the centimeters corresponding to 10⁻¹ meters.
10⁻¹ m × (10²cm/1 m) = 10 cm
1 dm = 10⁻¹ m
10⁻¹ m = 10 cm
Due to the transitive property, 1 decimeter is equal to 10 centimeters.
Answer:
6.75
Step-by-step explanation:
h=hat, s=scarf
5h + 1s = $47 (equation 1)
2h + 2s = $40 (equation 2)
multiply equation 1 by 2 , we get: 10h + 2s = $94 (equation 3)
equation 3 minus equation 2, we get:
8h = $54 ⇒ h = $6.75 ⇔ 1 hat cost $6.75
substitute h = $6.75 into equation 2 to find s,
2($6.75) + 2s = $40
$13.5 + 2s = $40
2s = $26.5
s = $13.25 ⇔ 1 scarf cost $13.25
I guess he needs to save $4 more to buy the shoes
