A student is attempting to isolate the variable t in the literal equation below. Which statement best applies to the sample mathematical work shown? Given: 2t + s – 4 =8 – s
Step 1: I first add 4 to both sides, resulting in 2t + s = 12 – s.
Step 2: I then subtract s from both sides, resulting in 2t = 12 – 2s.
Step 3: I then divide both sides by 2, giving a final answer of t = 6 – s.
A. the student failed to add the proper quatity in step 1
B. the student failed to subtract 2s properly in step 2
C. the student failed to divide both sides by 2 properly in step 3.
D. the mathematical work is correct as written.

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
