The sunnier it is outside, the more sunglasses will be worn ☀️
12x+y=10 -----> 12x + y = 10
-3=3x+3y ------> -12x - 12y = 12 (multiplied by -4)
-11y = 22
y= -2
12x - 2 = 10
x = 1
Answer: SECOND OPTION
Step-by-step explanation:
You must find the ratio of the sides of the triangle, as following:
Therefore, the ratio of the areas is:
Now you must multiply the area of the larger triangle by the ratio obtained above, therefore, you have that the result is:
≈
2:4:2.....added = 8
2/8 (56) = 112/8 = 14
4/8 (56) = 224/8 = 28
2/8 (56) = 112/8 = 14
14:28:14
Let's see how many pages he spellchecks in 1hrto start with,
20min is 1/3 of an hr so multiply both numbers by 3
20*3=60min or 1hr
14*3=42
So he spell checks 42 pages in an hour now let's multiply that by 5.5
1hr*5.5=5.5hrs
42*5.5=231
He spellchecks 231 pages in 5.5 hrs
