Answer:
x = 6, y = -1.
Step-by-step explanation:
7x = 3y + 45
4x + 5y = 19.... (1)
Rearranging the first equation:
7x - 3y = 45-----(2)
Multiply equation (1) by 3 and equation (2) by 5:
12x + 15y = 57
35x - 15y = 225
Adding :
47x + 0 = 282
x = 282 / 47 = 6.
To find the value of y substitute x = 6 into equation (2):
7(6) -3y = 45
-3y = 45 - 42 = 3
y = 3/-3 = -1.
Answer:
x = 9.5
Step-by-step explanation:
We see that the entire length of DF is equal to 34. That means segment DE and segment EF must combine to equal 34:
3x - 6 + x + 2 = 34
4x - 6 + 2 = 34
4x - 4 = 34
4x = 38
x = 9.5
10 times 12 equals 120.<span>

Step-by-step explanation:
Ace:
15800 x (-2/100) = -316
15800 - 316 = 15485
Beta:
17425 x (-3/100) = -522.75
17425 - 522.75 = 16902.25
Carro:
21280 x (-1.5/100) = -319.2
21280 - 319.2 = 20960.8
Delta:
24172 x (-1.8/100) = -435.096
24172 - 435.096 = 23736.90
