The probability of pulling out a green tie is 4 in 16, or 1 in 4 (25% chance of pulling a green tie).
33.3 square feet
Explanation: 8+8= 16+4= 20 + the top which should not be much more than 8.
Hope this helps:)
4x + 16 = -2
Product = multiplication
“Of a number and ..”= a variable which is most likely X
Increased= addition
Is= equals
Answer:
x=2/5, y=11/5
or x=−1y = 2
Step-by-step explanation:
Substitute y=3x+1 in x2+y2=5 to obtain
x2+(3x+1)2=5 ⇒ 10x2+6x−4=0
Hence
5x2+3x−2=0 ⇒ 5x2+5x−2x−2=0 ⇒5x(x+1)−2(x+1)= 0 ⇒ (5x−2)(x+1)=0
Hence
either
x=2/5, y=3×2/5+1=11/5
or x=−1, y=3×(−1) +1 = −2
