Answer:
x =-2.1
Step-by-step explanation:
X/2+10=8.95
Subtract 10 from each side
X/2+10-10=8.95 -10
x/2 =-1.05
Multiply each side by 2
x/2*2 =-1.05*2
x =-2.1
$21.22
Multiply 19.74 times 0.075 (7.5% converted to a decimal) to get 1.48 (the amount of tax) and add that to the cost of the meal (19.74)
To answer this youd have to set up a proportion. 5/2 is the ratio of weight on earth and mars respectively. The other side has to have the same ratio where 125lbs is the weight on earth and x is the weight on mars. The equation would look like 5/2=125/x. Youd have to cross multiply, and would get (125)(2)=5x. Solve for x to find the weight on mars
