Answer:
3/4
Step-by-step explanation:
Answer: 3/4x - 3
Step-by-step explanation:
Let his sister's sale be represented by x.
Since we are informed that Keiko sold 3 less than three-fourths of his sister's sales, the expression that represents what Keiko sold will be:
= (3/4 × x) - 3
= 3/4x - 3
Sorry idk, but I’ll try to do it
sin 40° = 0.6428
<u>Step-by-step explanation:</u>
The complementary ratio of sine is cos and vice-versa.
sin θ = cos (90 - θ)
cos θ = sin (90 - θ)
So cos 50° = sin (90 - 50)°
= sin 40°
sin 40° = 0.6428
This indicates that the complement of cos 50° is sin 40° which is equal to 0.6428.
Answer:
(x-6)*(x+1)=0
Step-by-step explanation:
1) move the 5x to the left side. x^2-5x-6=0
2) find two numbers that add up to -5 AND multiply to -6. (x-6)*(x+1)=0 (-6×1 = -6 ;-6+1=-5)
