Answer:
$300
Step-by-step explanation:
Let D = Dave's savings and S = Sam's savings.
(1) D/S = 5/4
(2) (D – 40)/(S-40) = 13/10 Multiply (1) by 4S
(3) 4D = 5S Multiply (2) by 10(S-40)
10(D - 40) = 13(S - 40) Remove parentheses
(4) 10D – 400 = 13S - 520 Solve (3) for S
S = (4/5)D Substitute into (4)
10D – 400 = 13(4/5)D - 520 Multiply each side by 5
50D – 2000 = 52D – 2600 Subtract 50D from each side
-2000 = 2D – 2600 Add 2600 to each side
600 = 2D Divide each side by 2
D = $300
Dave's savings at first were $300.
complementary angles are angles whose measures equals 90° when added. so to find the measure of this angle, we subtract 25° from 90°. the measure of the angle is 65°.
Answer:
A. 3/5
Step-by-step explanation:
To simplify a fraction, we need to find the Greatest Common Factor. The Greatest Common Factor is the highest number both the numerator and denominator can be divided by and still be a whole number. In our case the Greatest Common factor is 8. <u>Now all we do is divide the numerator and denominator by 8 and get our simplified fraction</u>. Image provided below of the "equation".
