The cost of 2 jackets and 3 skirts was sh 1800. After the cost of a jacket and that of a skirt was increased by 20%,the cost of
nadya68 [22]

Answer:

New cost of jacket = 1.2x=1.2\times 600=720\ \text{sh}

New costs of skirt = 1.2y=1.2\times 200=240\ \text{sh}

Step-by-step explanation:

Let original cost of jacket = x

original cost of skirt = y

The equation will be

2x+3y=1800

New cost of jacket = 1.2x

New costs of skirt = 1.2y

The equation will be

6(1.2x)+2(1.2y)=4800\\\Rightarrow 7.2x+2.4y=4800

The equations are

2x+3y=1800  \times 0.8

7.2x+2.4y=4800

1.6x+2.4y=1440

7.2x+2.4y=4800

Subtracting the above two equations we get

-5.6x=-3360\\\Rightarrow x=\dfrac{3360}{5.6}\\\Rightarrow x=600

7.2\times 600+2.4y=4800\\\Rightarrow y=\dfrac{4800-7.2\times 600}{2.4}\\\Rightarrow y=200

New cost of jacket = 1.2x=1.2\times 600=720\ \text{sh}

New costs of skirt = 1.2y=1.2\times 200=240\ \text{sh}.

Logs are stacked in a pile. The top row has 15 logs and the bottom row has 24 logs. How many logs are there in the stack?
ziro4ka [17]
There are two ways you can do this. You can use the longer way:
15+16+17+18+19+20+21+22+23+24 = 195 (starting from the top row, which has 15 logs, up until the bottom row, which has 24 logs, on condition that each second row has one log more than the previous one)

You can also use the formula (where n is the number of rows)
x= (n(first term+last term))/2
x= (10(15+24))/2
x= (10*39)/2
x=390/2
x=195

Either way, there are 195 logs in the stack.

What is the area of the real backyard?
prohojiy [21]
50 meters, because if 4cm is 5 m, then it would be 5( 4cm, which equals 5m) multiplied by 10( 8cm÷4cm= 2.     2×5m= 10). So 5m × 10m = 50m. Hope this helps!
