Answer:

French test

Step-by-step explanation:

We first calculate the scores as percentages:

#Spanish test:

$=\frac{score}{total}\times 100\%\\\\\\=\frac{27}{32}\times 100\%\\\\=84.38\%$

#For the French test, her percentage is:

$=\frac{score}{total}\times 100\%\\\\=\frac{19}{21}\times 100\%\\\\=90.48\%$

Since, 90.48$>84.38%, Claire did better in the French test.

1/5(2x - 10) + 4x = -3(1/5x + 4)
0.4x - 2 + 4x = -0.6x - 12
4.4x - 2 = -0.6x - 12
5x - 2 = -12
5x = -10
x = -2

David & Brad are competing in a 20-mile bicycle race. David rides 6.2 miles in 1/4 hour. Brad rides 11.9 miles in 1/2 hour.

Elodia [21]

David will finish first, because if you divide Brad's miles by 2 to his miles in a 1/4 of an hour are 5.95 miles. This means David went 6.2 miles in the same time that Brad went 5.95. Therefore, David will finish first.
