Step One
Multiply both sides by 80
7/8(x - 1/2)*80 = (-49/80) * 80
Step Two
7(x - 1/2 ) * 10 = - 49 Divide both sides by 7
(x - 1/2) * 10 = -49/7
(x - 1/2) * 10 = - 7 Remove the brackets on the left.
10x - (1/2)*10 = -7
10x - 5 = - 7 Add 5 to both sides.
10x = -7 + 5
10x = -2 Divide by 10
x = -2/10
x = - 0.2
Step Three
Check
We better check this one.
7/8*(-0.2 - 1/2)
7/8* (-.2 - 0.5)
7/8* (-0.7)
- 4.9/8 Now you can do one of two things. The easiest and simplest is to multiply top and bottom by 10
-4.9*10 / 8 * 10
-49 / 80 Which is the same as the right hand side.
Answer:
The exponential form of this would be (7x)^3/2
Step-by-step explanation:
The square root symbol is the same as writing raised to the 1/2. So we can rewrite the equation as:
[(7x)^1/2]^3
Then we can multiply the two exponents in this case giving us
(7x)^3/2

Step-by-step explanation:
just got this question on edge
Answer:
I don't know what you said
Step-by-step explanation:
But thanks for the points.
A sum of 5 from two cubes is ALWAYS one odd and one even, so the condition does not change anything whatsoever.
To roll a 5, we can have (1,4),(2,3),(3,2),(4,1) out of a sample space of 36 outcomes. So the probability is 4/36, or 1/9.
