If you talking about reducing the fraction it is 1/3.
Answer:
In the number 528.8 the value of 8 in the ones place is 10 times the value of 0.8 in the tenths place
Step-by-step explanation:
we have
The number 528.8 miles
Rewrite the number in digits value

so
The value of the ones digit is 8 ones or 8
The value of the tenths digit is 0.8 tenths or 0.8
Find the quotient
8/0.8=10
therefore
In the number 528.8 the value of 8 in the ones place is 10 times the value of 0.8 in the tenths place

let AB = E
⇒ (AB) (7 m) = (1.75 m) ( BC + AB)
(AB) (7 m) = (1.75 m) (1.5 m + AB)
= 2.625 m² + (1.75 m ) (AB)
(AB) (7 m - 1.75 m) = 2.625 m²
∴ AB = 2.625 m² ÷ (5.25 m)

⇒ the length of AB is 0.5 m</span>
Question:
The relationship between t and r is expressed by the equation 2t+3r+6 = 0. If r increases by 4, which of the following statements about t must be true?
Answer:
The value of t is reduced by 6 when the value of r is increased by 4
Step-by-step explanation:
Given

Required
What happens when r is increased by 4
<em>-------- Equation 1</em>
Subtract 2t from both sides

--- <em>Equation 2</em>
When r is increased by 4, equation 1 becomes
Note that the increment of r also affects the value of t; hence, the new value of t is represented by T
Open bracket
Rearrange

<em>Substitutr -2t for 3r + 6 [From equation 2]</em>

Make T the subject of formula

Divide both sides by 2


This means that the value of t is reduced by 6 when the value of r is increased by 4
Answer:
-55
Step-by-step explanation:
It would be -55 because the exponent is 4. So, that would leave -55 to be the right answer.
