Answer:

x = 7

Step-by-step explanation:

Distribute the 2 on the right and the -1 on the left: 13 - 2x - 2 = 2x + 4 + 3x

Combine like terms on each side of the equation: 11 - 2x = 5x + 4

Add 2x to both sides, and subtract 4 from each side: 7 = 7x

Divide both sides by 7: x = 7

One day Akash walked 2/3 km from home to school .On his return he took another route which was 3/5 km long .How many km did Akas

Andreas93 [3]

Answer:

Akash walked $1\frac{4}{15}$ kilometers in all.

Step-by-step explanation:

Given that:

Distance covered while walking to school = 2/3 km

Distance covered while walking back = 3/5 km

We will add the distance.

Total distance walked = $\frac{2}{3}+\frac{3}{5}$

Total distance walked = $\frac{10+9}{15}$

Total distance walked = $\frac{19}{15}=1\frac{4}{15}\ km$

Hence,

Akash walked $1\frac{4}{15}$ kilometers in all.

The following chart shows a store’s coat sales for two years.

STALIN [3.7K]

Answer:

Sales of trench coats increased 8.3 percentage points faster than total coat sales.

Step-by-step explanation:

2006:

top coats is 297,

parkas is 210,

jackets is 213,

raincoats is 137,

trench coats is 103

Total: $297+210+213+137+103=960$

2007:

topcoats is 223,

parkas is 210,

jackets is 285,

raincoats is 259,

trench coats is 127

Total: $223+210+285+259+127=1,104$

Percent increase in total sales:

$\dfrac{1,104-960}{960}\cdot 100\%=15\%$

Percent increase in sales of trench coats:

$\dfrac{127-103}{103}\cdot 100\%\approx 23.3\%$

Since $23.3\%-15\%=8.3\%,$ sales of trench coats increased 8.3 percentage points faster than total coat sales.
