X/58 (is roughly) 30
x/58 = 30
Multiply 58 on both sides.
x = 1,740
So it has to be c. 1,843
$5. Subtract the cost of the magazine, $3, from the total cost, $28. Now you have $25 then you divide it by the amount of notebooks you have.
8/x^4
I multiply to get everything out of the Parentheses.
Then a lot more steps
But the answers is 8 over x to the power of 4
Answer:
x = 45°
Step-by-step explanation:
<u>Vertical Angle Theorem</u>
When two <u>straight lines intersect</u>, they form two pairs of angles. The vertically opposite (non-adjacent) angles are <u>congruent</u> (equal).
From inspection of the given diagram, the <u>straight line with points C and D</u> and the <u>straight line with points F and G</u> intersect at <u>point E</u>.
Therefore, angles ∠FEC and ∠DEG are vertically opposite, and so they are equal.
From inspection of the diagram:
- ∠FEC = x°
- ∠DEG = 20° + 25° = 45°
Therefore:
⇒ ∠FEC =∠DEG
⇒ x = 45°
17. c You plug in (1,1) and it works
18. d You find all the possible x and y values and see if they fit in with the answers
19. slope = 4/3 y-intercept = -3 m is 4/3 and b = -3 tells us slope and y-i
