So you basically plug in the x value beside the 5 so if your on number 3 the answer would be 5(3) which is 15
Answer:
9
Step-by-step explanation:
3/4 = x/12
Cross-multiply: 36 = 4x
x = 9
Answer:
Add all of them together
Step-by-step explanation:
You have to add the numbers and that gives you the sum
3(3x - 2)
Distribute (multiply) 2 inside the parentheses.
3 * 3x and 3 * -2
9x - 6
1) you can buy 6 candy bars because $5.10 / $0.85 =
6.
To check: 6*0.85=5.10
2) you can find the answer by adding 3 to 12. 3+12=15 n=15 and it said n can be greater than or equal so
N(greater than or equal to sign) 15.
To check: 15-3=12
12=12
16-3>12
13>12
7) x-7=12
+7 +7
X=19
To check: 19-7=12
12=12
8) y/8=7
*8 *8
Y= 56
To check: 56/8=7
7=7
9) 10-4x=6x
+4x +4x
10=10x
/10 /10
X=1
To check: 10-4(1)=6(1)
10-4=6
6=6
Hope this helped!
