Answer:
Step-by-step explanation:
Lets try to simplify each to check which one is incorrect so it will be NOT true
first one is :
distribute the exponent so :
CORRECT
Second one is :
CORRECT because anything raised to exponent 0 is 1 .
Last one is :
so Last is<em> INCORRECT</em>
3:8 can also be written as 3/8
<span>12:32 can also be written as 12/32
</span>
<span>So thus 3:8 is equivalent to 12:32</span>

Answer: 97/112</h3>
================================================
How to get this answer:
Midpoint formula: (A+B)/2 = C
A and B are the endpoints with C as the midpoint
A = 7/8
B = 6/7
A+B = 7/8 + 6/7
A+B = 49/56 + 48/56
A+B = (49+48)/56
A+B = 97/56
(A+B)/2 = (97/56) divided by 2
(A+B)/2 = (97/56) times (1/2)
(A+B)/2 = (97*1)/(56*2)
(A+B)/2 = 97/112
Answer:
f(-2) = 3
Step-by-step explanation:
Given that,
f(x) = x + x + 7
We need to find the value of f(-2).
Put x = -2 in the given function.
f(-2) = (-2) + (-2) + 7
= -2-2+7
= -4+7
= 3
Hence, the value of f(-2) is equal to 3.
Answer:
The value of x is 13
Step-by-step explanation:
To solve this, we create a proportion. First create two fractions that compare corresponding sides.
2/8 = 2.5/x - 3
Now cross multiply to solve for x.
8 * 2.5 = 2(x - 3)
20 = 2x - 6
26 = 2x
13 = x
