The correct question is
<span>Sandra needs to buy 21/25 meters of chain for a home project. Which decimal number is equal to the fraction 21/25?
we have that
21/25--------> multiply by (4/4)
(21/25)*(4/4)=(21*4)/(25*4)-----> 84/100------> 0.84
the answer is the option
0.84

Answer:
a) x-intercepts at -6 and 2
b) y-intercept at -12
c) minimum at (-2, -16)
Step-by-step explanation:
Answer: The answer is 147° and 33°.
Step-by-step explanation: We are given a figure in which the line DE is parallel to the line FG and AG is a tranversal. We are to find the value of 'x' and 'y' from the figure.
Also, given that
∠ABE = (5y - 18)°.
We can see from the figure that ∠DBG and ∠ABE are vertically opposite angles, so they must be equal.
That is,

Also, since ∠DBG and ∠FGB are interior angles on the same side of the transversal, so their sum is 180°.
That is

Adding equations (i) and (ii), we get

and from equation (ii), we get

Thus, x° = 147° and y° = 33°.
