Answer:
The answer is 0.75x.
Step-by-step explanation:
If the dress is on sale for 25% off, then we know that the new sale price of the dress is x - (25/100)x = x - 0.25x = 0.75x.
This equation is not correct. Because,
And
The only possible, solution for this equation would be, x=0. Because,
for x=0 :
Answer:
21
Step-by-step explanation:
We are to divide the expression
15÷5/7
We can change the sign to a product sign and multiply 15 by reciprocal of 5/7
Reciprocal of 5/7 = 7/5
Multiply with 15
= 15 × 7/5
= 15/5 × 7
= 3 × 7
= 21
Hence the resulting value of the expression is 21
ANSWER
EXPLANATION
From the mnemonics SOH-CAH-TOA.
We want to find the cosine of y
CAH means cosine ratio involves adjacent over the hypotenuse.
From the right by triangle, the side ajacent to angle y is 64 units and the hypotenuse is 80 units.
