Answer:
The numbers are -14,-13 and -12
Step-by-step explanation:
<u><em>The correct question is </em></u>
Find three consecutive integers such that the sum of the first, twice the second and three times the third is -76. What is the number?
Let
x ----> the first consecutive integer
x+1 ---> the second consecutive integer
x+2 ---> the third consecutive integer
we have that
![x+2(x+1)+3(x+2)=-76](https://tex.z-dn.net/?f=x%2B2%28x%2B1%29%2B3%28x%2B2%29%3D-76)
solve for x
apply distributive property
![x+2x+2+3x+6=-76](https://tex.z-dn.net/?f=x%2B2x%2B2%2B3x%2B6%3D-76)
Combine like terms
![6x+8=-76](https://tex.z-dn.net/?f=6x%2B8%3D-76)
subtract 8 both sides
![6x=-76-8](https://tex.z-dn.net/?f=6x%3D-76-8)
![6x=-84](https://tex.z-dn.net/?f=6x%3D-84)
Divide by 6 both sides
![x=-14](https://tex.z-dn.net/?f=x%3D-14)
so
![x+1=-14+1=-13](https://tex.z-dn.net/?f=x%2B1%3D-14%2B1%3D-13)
![x+2=-14+2=-12](https://tex.z-dn.net/?f=x%2B2%3D-14%2B2%3D-12)
therefore
The numbers are -14,-13 and -12
Answer:
Sources of electrical current
Step-by-step explanation:
Based on the information given the reason why
He/ She places a compass at different positions on a wall until the compass needle change to a direction was because the construction worker
was most likely using the compass to find the Sources of an ELECTRICAL CURRENT or where the ELECTRICAL CURRENT originated from reason been that ELECTRICAL CURRENT is the movement of electric charge from cathode to anode .
Answer: There are 5 nickels and 10 quarters.
Step-by-step explanation:
Let x = Nickels , y= Quarters.
Then x+y = 15
⇒ y=15-x (i)
1 nickel = 5 cents , 1 quarter = 25 cents
$2.75 = 275 cents [ 1 dollar = 100 cents ]
Then, 5x+25y= 275 (ii)
Substitute value of y from (i)
5x+25 (15-x)=275
⇒ 5x + 375 - 25x =275
⇒ -20x= 275-375
⇒ -20x= -100
⇒ x = 5 [divide both sides by -20]
Put this in (i) , we get y= 15-5=10
Hence, there are 5 nickels and 10 quarters.
Answer: 0.009 is ten time as many as 0.009. 0.09 divided by 10, and that gave me 0.009. So 0.9 is 10 as many as 0.009.
