1). 16 Y= 164. ( then divided)
Y= 164 : 16
Y= 41 : 4
Y = 10 +1/4

2) 8z = 64. (then divided)
z= 64 :8
z= 8


3. D = A•B•C. ( divided)
D : A•B = C

C= D:AB

c. c= d divided by ab

Solution:

(1) we have been asked to find the value of y in this equation 16y=164.

The given equation can be solved as below

16y=164.\\
\\
\text{Divide both the sides of 16 we get}\\
\\
y=10.25=10 \frac{1}{4} \\

Hence the correct option is a

2.Find the value of Z in the following equation 8Z=64

we are given that

8Z=64\\
\\
\text{Divide both the sides by 8 we get}\\
\\
z=8

Hence the correct option is a

3.given the formula D=ABC,we have been asked to find the formula for C.

we can solve it as below

D=ABC\\
\\
\text{Divide both the sides by AB we get}\\
\\
\frac{D}{AB}=C\\
\\
C= \frac{D}{AB}\\

Hence the correct option is C.

If x-1/3 = k and k = 3, what is the value of x ?<br> A) 2<br> B) 4<br> C) 9<br> D) 10
Semenov [28]

Answer:

None of the above

Step-by-step explanation:

x-1/3 = k

We know that k=3, so we can substitute that into the equation

x-1/3 = 3

Add 1/3 to each side

x-1/3 + 1/3 = 3+1/3

x = 3 1/3 or as an improper fraction 10/3

What is the solution to the problem expressed to the correct number of significant figures? 15. 11 (142 × 16. 5) = ? A. 2,358 B.
olchik [2.2K]

The solution to the problem expressed  2358.

<h3>What is the meaning of significant figure?</h3>

Significant figure It is defined as the minimum number of digit us needed to express a number in scientific notation.

Therefore we get,

15.11+(142\times16.5)

First we have to multiply the given digits as per rule.

=15.11+2343

Now we will add both the digits, we get

=2358.11

As per given expression, we conclude that the number of significant figure is 4.

So, the answer will be, 2358.

Therefore, the correct option is, 2358.
