Insert either < or > in the shaded area between the numbers to make the statement true. $$-\pi \quad-3.5$$
Determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. $$x-0.02(x+200)=0.98 x-4$$
Your computer store is having an incredible sale. The price on one model is reduced by 40%. Then the sale price is reduced by another 40%. If x is the computer鈥檚 original price, the sale price can be modeled by Your computer store is having an incredible sale. The price on one model is reduced by 40%. Then the sale price is reduced by another 40%. If x is the computer鈥檚 original price, the sale price can be modeled by $$ (x-0.4 x)-0.4(x-0.4 x)$$ A. Factor out \((x-0.4 x)\) from each term. Then simplify thre sulting expression. B. resulting expression. b. Use the simplified expression from part (a) to answer these questions. With a 40% reduction followed by a 40% reduction, is the computer selling at 20% of its original price? If not, at what percentage of the original price is it selling?
