Answer:
x=3
Step-by-step explanation:
12x-14=4x+10
Subtract 4x from each side
12x-4x-14=4x-4x+10
8x - 14 = 10
Add 14 to each side
8x - 14+14 = 10+14
8x = 24
Divide each side by 8
8x/8 = 24/8
x = 3
Because it specialises the groups that go into the number.
Answer:
3/4
Step-by-step explanation:
Use the rise over run equation
In the equation f(n) = 2n - 7
f(11) = 15
Answer:
B. 5
D. 9
F. 7
Step-by-step explanation:
A triangle has sides a,b and c:
And a < b+c , b < a+c and c < b+a
Here, a = 4 and b = 7
Find c?
So, 4 < 7+c , 7 < 4+c and c < 4+7=11
A. 11 False, it doesn't satisfies inequality third
B. 5 True
C. 17 False, it doesn't satisfies inequality third
D. 9 True
E. 3 Not true it doesn't satisfies second inequality
F. 7 True
