3 goes into both 3x and 18
Answer:
4
Step-by-step explanation:
5 = (4 + 8 + 3 + 6 + x) / 5
25 = 21 + x
x = 4
hope it helps :3
The one in the middle is 12 for the median = 8
Answer:
y = 4
x = -1
Step-by-step explanation:
4x + 2y = 4 Eq. 1
3x - y = -7 Eq. 2
from the Eq. 2
3x = y - 7
3x + 7 = y Eq. 3
Replacing the value of the Eq. 3 in the Eq. 1
4x + 2(3x+7) = 4
4x + (2*3x + 2*7) = 4
4x + (6x + 14) = 4
10x + 14 = 4
10x = 4 - 14
10x = - 10
x = -10/10
x = -1
from the Eq. 3
3x + 7 = y
3*-1 + 7 = y
-3 + 7 = y
4 = y
Check:
from the Eq. 1
4x + 2y = 4
4*-1 + 2*4 = 4
-4 + 8 = 4
Answer: 4
Step-by-step explanation:
20 divided by 5+8+3 times 5.
Which can be broken down as 20 divided by 16 times 5.
First, multiply 16 by 5 and that gives you 80. 80/20 = 4, and there’s your answer.
