Is the same as seven less than a number(x) : x-7
now in your case what would be the answer ?
Answer:
360 for first place and 240 for second
Step-by-step explanation:
Let's say f is the first place prize, and s is the second prize.
Amaal: 4f + 2s = 1920
Brian: f + 3s = 1080
Now we can isolate and substitute.
f = 1080 - 3s
4(1080 - 3s) + 2s = 1920
4320 - 12s + 2s = 1920
10s = 4320 - 1920
10s = 2400
s = 240
f = 1080 - 3*240
= 1080 - 720
= 360
Answer:
Step-by-step explanation:
Use the Pythagorean theorem to find the length x of the third side.
x² + 6² = √90²
x² = 90-36 = 54
x = √54 = 3√6
Answer: 1. n= -8.86 2. k=17.5
explanation: in equation one subtract 3.35 from both sides. in equation two divide both sides by -3.4
