The common ratio is 2:1, or dividing by 2
Solve the following system using elimination:
{x - 2 y = -23 | (equation 1)
{x - y = 7 | (equation 2)
Subtract equation 1 from equation 2:
{x - 2 y = -23 | (equation 1)
{0 x+y = 30 | (equation 2)
Add 2 × (equation 2) to equation 1:
{x+0 y = 37 | (equation 1)
{0 x+y = 30 | (equation 2)
Collect results:
Answer: {x = 37 , y = 30
Answer:
The scale is 5ft represents 1 inch
Step-by-step explanation:
from length conversions 1ft = 12 inches
On the scale model, the height of the statue is 8 inches. The actual height is 40 ft.
40ft = 40*12 inches =480 inches
divide 480 by 8 inches = 480/8 =60
the height of the statue was scaled down using;
60 inches represents 1 inch
convert 60 inches to ft by dividing by 12. 60/12 =5ft . Thus
5ft represents 1 inch
The scale is 5ft represents 1 inch
The value is 3
Step-by-step explanation:
To simplify the expression , we can reciprocal the term to and multiply, so that we can easily simplify the terms.
Thus, the expression becomes,
Multiplying the terms, we get,
Dividing the terms,
Thus, the value of the expression is 3.
