Show your work 2 1/5 × 3 1/8

vesna_86 [32]

Solution

For this case we can do the following:

$2\cdot\frac{1}{5}=\frac{2\cdot5+1}{5}=\frac{11}{5}$ $3\cdot\frac{1}{8}=\frac{3\cdot8+1}{8}=\frac{25}{8}$

And then if we multiply we got:

$\frac{11}{5}\cdot\frac{25}{8}=\frac{55}{8}$

Help with #7 please :) i’ll mark you brainily

TEA [102]

Answer:

x = 11

Step-by-step explanation:

The student didn't divide two on both sides in the step 1. This the mistake that the student made.

The correct solution

2√( 3x + 3 ) = 12

Divide 2 on both sides,

2√( 3x + 3 ) / 2 = 12 / 2

√( 3x + 3 ) = 6

Square on both sides,

[ √( 3x + 3 ) ]² = 6²

3x + 3 = 36

3x = 36 - 3

3x = 33

x = 33 / 3

x = 11
