Step-by-step explanation:
.19 = 19/100
.864 = 86.4/100
.5348 = 53.48 /100
I multiplied the decimal by 100 to get what it was before which is the same as moving two decimal places to the right and divided by 100

Answer: Algebra acts as a tool to improve communication because much like learning a new language, you have to take baby steps before you can fully get it. This can improve communication because you're learning something new with the help of others.
Answer:
False.
Step-by-step explanation:
The ratio is 1:500, which means that the model will be 500 times smaller than the real deal.
The real airplane is 50 metres, or 5,000 centimetres. The model is 50 cm. 5,000 / 50 = 1,000 / 10 = 100 / 1 = 100. Since 100 is NOT equal to 500, the answer is false.

Step-by-step explanation:
Question 3: (4, -3)
Solving through elimination: Multiply the first equation by -3.
-3x+6y=-30
3x-5y = 27
Add. The x drops out.
y= -3
Substitute -3 in for y.
x-2y=10
x-2(-3)=10
x+6=10
x=4
Question 4: (2,5)
Solve through elimination: Multiply the second equation with 3.


3/2= 6/4
15/4x=7.5
x=2
3/2 (2) + y = 8
3+ y =8
y=5
Question 5: (6,4)
Use your graph to graph.

Slope of -1/3
Y-intercept of 6 (0,6)
X-intercept of 18 (18,0)

Slope of 3/2
Y-intercept of -5 (0,-5)
X-intercept of
