Answer:

The constant of variation is 1.6.

Step-by-step explanation:

y = kx and x = 5 when y = 8 and k = the constant of variation.

8 = k*5

k = 8.5 = 1.6.

Answer:

8/5

Step-by-step explanation:

Plug in the point given into

y=kx.

The number you get for y will be your constant of variation, also know as constant of proportionality.

(x,y)=(5,8) implies 8=k(5)

So in solving that equation we just need to divide both sides by 5 giving us:

8/5=k.

The list price of a diamond ring is $662. The jeweler is offering a chain discount of 15% less 10%. What is the final net price

Tom [10]

Your answer is 506.44.

multiply 662 x .10 now minus that answer from 662 to get 595.80

now multiply that by .15

now minus that by 595.80

gives you 506.43

Which of these expressions CANNOT be simplified by combining like terms?

densk [106]

$5ab^{3} +7-3a^{2} b ^{2} +a^{3}b+10$ can be simplified to by adding the 7 and 10 to get $a^{3}b-3a^{2} b ^{2}+ 5ab^{3} + 17$ .

$5ab^{3}+3a^{2}b^{2}+a^{3}b -10$ cannot be simplified any more by combining like terms.

By distributing the 2b into the parentheses, you can simplify the expression:
$5ab^{3}+2b(3ab^{2})+a^{3}b-10\\
5ab^{3}+6ab^{3}+a^{3}b-10\\
11ab^{3}+a^{3}b-10$

Here you can just add:
$5a^{3}b^{3}+3a^{2}b^{2}+a^{3}b^{3}-10ab\\
6a^{3}b^{3}+3a^{2}b^{2}-10ab$

Thus, the only expression that cannot simplify any more using adding like terms is the second, $5ab^{3}+3a^{2}b^{2}+a^{3}b -10$ .

AHHHHHHHHHH I DON'T LIKE MATH!!!!!!!!!!!!!!!!

REY [17]

Answer:

The answer is 5 1/16

Step-by-step explanation:

3/2 x 3/2 x 3/2 x 3/2

3/2 x 3/2 = 9/4

9/4 x 3/2 = 27/8

27/6 x 3/2 =81/16

Turn 81/16 into a mixed fraction and it’s 5 1/16

Therefore, the answer is 5 1/16
