Usually, you're asked to model a situation with an equation. Here, you're given the equation and asked what situation it models.
The features of the equation that are of interest are ...
- multiplication of the unknown value by 17.35
- comparison of that product to 624.60, expecting the product to be greater than that value
The first two offered scenarios involve addition of an unknown value, not multiplication.
The third offered scenario compares a purchase price to a budget amount. Answering a question like this involves a "less than" comparison, not a "greater than" comparison.
The last offered scenario involves finding a variable value that will result in the product 17.35x exceeding 624.60—exactly what the given inequality models.
The appropriate choice is ...
... J Daren earns $17.35 ...
Area of rectangle = length x width (product of the two adjacent sides)
Length of wx = sqrt((3 - 0)^2 + (4 - 1)^2) = sqrt(3^2 + 3^2) = sqrt(18) = 4.24
Length of xy = sqrt((-1 - 3)^2 + (8 - 4)^2) = sqrt((-4)^2 + 4^2) = sqrt(32) = 5.66
Area = 4.24 x 5.66 = 24 square units.
Answer:
Step-by-step explanation:
Study the steps used to solve the equation.
Given: StartFraction c Over 2 EndFraction minus 5 equals 7
Step 1: StartFraction c Over 2 EndFraction minus 5 plus 5 equals 7 plus 5
Step 2: StartFraction c Over 2 EndFraction plus 0 equals 12
Step 3: StartFraction c Over 2 EndFraction equals 12
Step 4: 2 (StartFraction c Over 2 EndFraction) equals 12 (2)
Step 5: c equals 24
