Write 8 is the whole number 11 is the <br>numerator and 20 is the denominator ​
PilotLPTM [1.2K]

Answer:

Fraction: 8 \frac{11}{20}

Decimal: 8.55

Step-by-step explanation:

8 11/20 is the answer because:

1) Since 8 is the whole number, 8 wouldn't be part of the fraction

2) The numerator is the top number in the fraction, so 11 is at the top since 11 is the numerator

3) The denominator is the bottom number in the fraction, so 20 is at the top since 20 is the denominator

8.55 is the answer because:

1) Since 8 is the whole number, 8 would be in front of the decimal point

2) When you multiply the fractions, you have to multiply until you get a hundred. Therefore, 20*5 = 100 and 11*5 = 55

Hope this helps!

BabaBlast [244]
Area of a triangle= \frac{1}{2} *base*height
A=\frac{1}{2} *(2x-6)*(x-2)
A=\frac{1}{2} ( 2x^{2} -4x-6x+12)
A=x^{2} -2x-3x+6
A=x^{2} -5x+6

Solve each system using SUBSTITUTION. Remember to check!
Annette [7]

Answer:

\left \{ {{x=3} \atop {y=-7}} \right.

Step-by-step explanation:

We can directly substitute y of the first equation to the second equation.

-2x - 1 = 3x - 16

5x = 15

x = 3

Substituting back to any of the two equations, we get y = -2(3)-1 = -7.  If you check with the second equation, y = 3(3)-16 = -7 as well.

Therefore \left \{ {{x=3} \atop {y=-7}} \right..
