Answer:
$80.15
Step-by-step explanation:
We can make an equation to solve this problem, that helps a lot. If h represented hours, we could make the equation 15.53h+s=157.8
Now we know that he worked 5 hours, so we can multiply 15.53 by 5 to simplify the equation.
15.53*5=77.65
So now the equation is 77.65+s=157.8.
Now, we can subtract 77.65 from both sides.
So now, our final equation is s=80.15
It cost $80.15 to buy supplies.
Hope this helps!
The answer will most definitely be C
Answer:
Four consecutive numbers are 2, 6, 10 and 14
Step-by-step explanation:
15(a² - 9d²) = 7(a² - d²)
15a² - 135d² = 7a² - 7d²
15a² - 7a² = 135d² - 7d²
8a² = 128d²
Putting the value of a = 8 in above we get.
8(8)² = 128d²
128d² = 512
d² = 512/128
d² = 4
d = 2
So, the four consecutive numbers are
8 - (3*2)
8 - 6 = 2
8 - 2 = 6
8 + 2 = 10
8 + (3*2)
8 + 6 = 14
