Answer:
The car drove for 1,024 miles.
Step-by-step explanation:
x=miles driven
y=days driven
448.76=29x+0.24y
448.76=29(7)+0.24y
448.76=203+0.24y
245.76=0.24y
y=1,024
Answer: 50%
Step 1 add 18+20 = 38
Step 2 add 10+9= 19
Step 3 divide 19 by 38 = 2
So if would be half which is equal to 50%
How much was he paid per hour
If you know the measurements of 2 sides not the height , you can apply Pythagorean theorem to find the height. Square root of the sum of the squared sides
The GCF of the three terms (9a, -18b and 21c) is 3
Rewrite each of the terms so 3 is a factor
9a = 3*3a
-18b = -3*6b
21c = 3*7c
So we can say...
9a - 18b + 21c = 3*3a - 3*6b + 3*7c
9a - 18b + 21c = 3(3a - 6b + 7c)
Answer: 3(3a - 6b + 7c)
If you distribute outer 3 to each of the inner terms and multiply, you'll get the original expression again.
