Answer:
No, Justin is incorrect.
Step-by-step explanation:
1. To find how much 18/40 as a percent is, we just multiply 18/40 by 100:
2. As you can see, 18/40 as a percent is 45%, not 35%. Therefore, Justin is incorrect.
It would most likely equal to 6. Hope this helped.
Step-by-step explanation:
AC and DB are the same length. Set the two to equal each other and solve for y.
9y + 1 = 8y +17
Subtract 8y from both sides:
y + 1 = 17
Subtract 1 from each side:
y = 16
Now you know Y you can find the the length of DB:
DB = 8y +17 = 8(16) +17 = 128 + 17 = 145
EB is half of DB:
EB = 145 / 2
EB = 72.5
The answer to this problem is -5x=8
Answer:
Step-by-step explanation:
y - x = -5
y = x-5
y = 2x² - 3x - 5
x-5 = 2x² - 3x - 5
2x² - 4x = 0
x² - 2x = 0
x(x - 2) = 0
x = 2, 0
(x,y) = (2,-3), (0,-5)
