Answer:
For the one including 4w the answer is - 7
The one with n/2 is - 12
Step-by-step explanation:
4w=-13-15
4w=-28
w=-7
Multiply by 2 on both sides
-24=n-12
-24+12=n
Always write it in the variables perspective.
n=-12
Answer:
28, 30, 32
Step-by-step explanation:
Three consecutive even numbers are three even numbers that are next to each other. For example, 2, 4 and 6 would be 3 consecutive even numbers.
With this sort of problem, you want to try to let each number be equal to one thing and then construct the same number of equations as you have variables:
Let's let,
Integer 1 = X
Integer 2 = Y
Integer 3 = Z
X + Y + Z = 90
We also know, that
Y = X + 2
And that
Z = X + 4
Now, we can sub these equations into the first equation. We do this so that we have everything represented as the same variable.
90 = X + (X+2) + (X+4)
90 = 3X + 6
84 = 3X
28 = X
So, the numbers are 28, 30 and 32
600/800 descansos porque mencionaste que se toma un descanso cada 3 cm pero se desliza 1 cm cada vez que se toma un descanso, así que solo cambia los 2 ma cm, que es 200 veces eso a 3 o 4 y obtendrás el número de descansos (acabo de adivinar)
Change percent to decimal which is 0.35 and multiply it by 550 to get 192.5 which is the amount taken off from the original price. So the total price after the discount is 357.5$
Answer: x < -9
Step-by-step explanation:
-8x > 72
x < -9 when dividing a negative number in an inequality, change the sign to opposite.
the number are less than -9.
