Answer:
$22.68
Step-by-step explanation:
21×.08= 1.68
21+1.68=22.68
Total cost =$22.68
Answer:This problem is about linear equations. We assume Dale drive X miles, and the total cost is $Y, then we can get:
Plan I: Y=38+0.11X
Plan II: Y=49+0.07X
When both plans cost the same, 38+0.11X=49+0.07X. We will get X = 275miles, and Y=$68.25
Step-by-step explanation:
Answer:
In triangle ABC and triangle CDA
AB=CD(given)
BC=DA(given)
AC=AC(common)
Thus triangle ABC and triangle CDA are congruent by SSS rule
The answer is 2×2×3
if needed to be multiplied together the answer is 12
