Answer/Step-by-step explanation:

This is a proportional relationship between amount of strawberries and the amount of bananas needed in making smoothie.

Thus, a constant of proportionality, k, is a ratio that exist between both quantities.

k = y/x = amount of strawberry/amount of bananas.

Since we are given that a recipe of smoothie contains 5 cups of strawberries for every 2 cups of bananas, therefore,

k = ⁵/2 = 2.5.

Any point that will be on the line shown must have the same value of k (y/x).

Thus, given the point (1, 2.5). The ratio between y and x is:

k = 2.5/1 = 2.5.

Since this also shows the same constant of proportionality as 2.5, therefore, the point is also on the line.

What is the measure of ACE in the diagram below?<br><br> A. 46<br> B. 104<br> C. 29<br> D. 58
beks73 [17]

Answer:

C

Step-by-step explanation:

The secant- secant angle ACE is half the difference of the measures of the intercepted arcs, that is

∠ ACE = \frac{1}{2} (AE - BD ) = \frac{1}{2} (104 - 46)° = \frac{1}{2} × 58° = 29° → C

Eight times the sum of 8 and some number is 17. What is the number?
OverLord2011 [107]
Edited answer: The number is:  "- 6" .
_______________________________________________

 8 (8 + x) = 16 ;  

in which "x" represents the number for which to be solved ;

8*8 + 8*x = 16 .

Edit:  64 + 8x = 16 ;

Subtract "64" from each side of the equation:

Edit:   64 + 8x − 64 = 16 <span>− 64 ;

to get:  8x = </span>- 48 ;

Divide EACH SIDE of the equation by "8" ; to isolate "x" on one side of the <span>equation ; and</span> to solve for "x" ;

Edit:     8x / 8 = -48 / 8 ; 

  Edit:    x = - 6 .
______________________________________________
The number is:  "- 6" .
______________________________________________
 Let us check our answer, by plugging in "-6" for "x" in the original equation:
______________________________________________
8 (8 + x) = 16 ; 

→ 8 [8 + (-6) ]  =? 16 ?? ; 

→ 8 (8 − 6 )  =? 16 ?? ; 

→ 8 (2)  =? 16 ?? ; 

→ 16 = ? 16 ??  Yes!
