Answer: red is 13.36
Blue is 93.625
Step-by-step explanation:
Let the red marbles be y
Based on the question,red is 4times which means 4y
And blue is 7times greater than red which means 7(4y)
Blue + red=107
7(4y) + 4y=107
28y+4y=107
32y=107
Divide both sides by 32
Y=3.34
Red =4y
Red= 4(3.34)
Red =13.36
Blue= 7(4y)
Blue=7(4×3.34)
Blue= 93.625
4*($19.99)=$79.96$79.96+($79.96*.0675)=$85.38 or $79.96*1.0675$85.38*.8=$68.29 .8 is the decimal form of 80%, which is the percentage you pay after receiving 20% off
Answer:
name them
A=(-2,5)
B=(-2,1)
C=(1,1)
sides:
AB=c=4
AC=b=√(3²+4²)=5
BC=a=3
then we do this
2p=a+b+c
2p=3+4+5=12
p=6
then we calculate the area:
√(p(p-a)(p-b)(p-c))
Area=√6(6-3)(6-4)(6-5)
Area=√(6×3×2×1)
Area=√36=6
Answer:
It is a rational number because the 
is 6.
