Q17:
one week = $560
52 weeks = 560 x 52 = $29120
Q18:
one year = $28500
52 weeks = 28500
1 week = 28500 ÷ 52 = $548
Q19:
5% of $300000 = 0.05 x 300000 = $15000
$15000 + $12000 = $27000
Answer:
28/6 yeah thats right wasp
Answer:
x = 28 (So it takes 28 hours for the temperature to reach 0°C.)
y = -70 (So the temperature when the experiment begins is −70°C.)
Step-by-step explanation:
To find the the x value, you remove the y value or replace it with 0.
0 = 5/2x - 70
Next you move the variable.
70 (2/5) = x (multiply 70 by 2 to get 140 and divide that by 5)
And now you simplify to get:
28
To find the y value, you remove the x value or replace it with 0.
y = 0 - 70
And now you simplify to get:
-70
x = 28
y = -70
So because 25%=1/4 we would know to multiply 9*4
Which would get our answer to be 36 :)
