If the sofa price is $900 more than the price of the chair, then: S=C+900.
If the total for the purchase of sofa and chair is $1200, then S+C=1200.
Use this info to select the correct system of equations. Note: you do not have to solve for S and C.
Answer:
70
Step-by-step explanation:
The simplest way to find the number is work backwards. If you know the final answer is 10, start with 10 and make the number x. Then set up the original equation.
0.5x-25=10
Then start working backwards(isolate).
0.5x-25=10
+25 +25
in other words, 10+25=0.5x. (the 25 cancels out because -25+25=0)
10+25=35, so 35=0.5x.
Now, instead of dividing by 2, multiply by 2(opposite again).
35=0.5x
/0.5(aka *2) /0.5(cancels out)
now you are left with 70=x, so the number is 70.
Draw a circle.
Split the circle into 5 sections. This represents the 5 inches.
Fill in 2 of those sections, those represent the reduction in height.
Count the empty sections. 5 -2 = 3 sections
Now you find the percent. 3/5 = 60%
You multiply the area by the scale factor twice. Here is an example: if we have a rectangle that has a length 3 and a height of 4 and the scale drawing with a scale factor of 2, how many times bigger is the scale drawings area? The original shape is 3 by 4 so we multiply those to find the area of 12 square units.
hope it helps!!!
