Answer:

Rhian did better in the Math test.  

Step-by-step explanation:

Given: Rhian scored 14 out of 17 in a Math test. In the English test she scored 31 out of 39.

To find: In which test did she do better?

Solution:

We have,

Rhian scored 14 out of 17 in a Math test.

Rhian scored 31 out of 39 in an English test.

So, first we need to find the percentage of the marks scored.

Percentage in the Math test =\frac{14}{17}\times100=82.35 \%.

Percentage in the English test =\frac{31}{39}\times100= 79.49\%.    

Clearly, the percentage in the Math test is greater than the percentage in the English test.

So, Rhian did better in the Math test.

Ede4ka [16]
Area of rectangular board = length (inches) x width (inches) = 12" x 16" = 192 in²

Area of the border is given as 128 in²

Adding the area of the board and the border gives (192 + 128)in² = 320 in²

Set this up as the algebraic equation (x + 12)(x + 16) = 320 and solve for x:

Remember to use the FOIL method, which is multiplying the terms in the order of first, outer, inner, last.

x² + 12x + 16x + 192 = 320

x² + 28x + 192 - 320 = 0

x² + 28x - 128 = 0

solve for the two x values:

(x + 32)(x - 4) = 0, and knowing we only need the positive x value

x = 4 or 4 inches is the width of the border
