Answer:
t = -5
Step-by-step explanation:
Solve for t:
5 (t - 3) - 2 t = -30
Hint: | Distribute 5 over t - 3.
5 (t - 3) = 5 t - 15:
5 t - 15 - 2 t = -30
Hint: | Group like terms in 5 t - 2 t - 15.
Grouping like terms, 5 t - 2 t - 15 = (5 t - 2 t) - 15:
(5 t - 2 t) - 15 = -30
Hint: | Combine like terms in 5 t - 2 t.
5 t - 2 t = 3 t:
3 t - 15 = -30
Hint: | Isolate terms with t to the left hand side.
Add 15 to both sides:
3 t + (15 - 15) = 15 - 30
Hint: | Look for the difference of two identical terms.
15 - 15 = 0:
3 t = 15 - 30
Hint: | Evaluate 15 - 30.
15 - 30 = -15:
3 t = -15
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 3 t = -15 by 3:
(3 t)/3 = (-15)/3
Hint: | Any nonzero number divided by itself is one.
3/3 = 1:
t = (-15)/3
Hint: | Reduce (-15)/3 to lowest terms. Start by finding the GCD of -15 and 3.
The gcd of -15 and 3 is 3, so (-15)/3 = (3 (-5))/(3×1) = 3/3×-5 = -5:
Answer: t = -5
So he has to read 500 and he already read 260 500 - 260 = 240. 240 divided by 30 equals 8. So the answer will be 8 days
Answer:
2 kilogram bag.
Step-by-step explanation:
To figure this out, we need to divide the price by the amount of kilograms. Lets start with the 3 kilo bag. Divide 42 by 3, let y equal the price per kilo
42/3=y
Divide
14=y
Now lets do the same with the 2 kilo bag. Divide 26 by 2. Let x be this number.
26/2=x
divide
13=x
The 2 kilo bag is better as its 13 pesos per kilo compared to the 3 kilo bag's 14 pesos per kilogram.
Joe: 24
John: 2/3 of 24 is 16
Jessie: 24 + 16 = 40; 1/5 of 40 is 8
Jessie makes $8 an hour.
