Answer: 6-7 bird houses?

Step-by-step explanation: Well, if in 3 hours she can make 2 bird houses, then in six she can make 4. If in 9 hours, she can make 6, so my guess is that she makes 6-7 bird houses in 10 hours?

Simplify the expression:<br><br> 5x + 8 – 13y – 4x – 18 + 16y

aleksandrvk [35]

$\text{Hey there!}$

$\text{Simply the equation: 5x + 8 - 13y - 4x - 18 + 16y}$

$\text{First you have to combine the \bf{like-terms}}$

$\text{5x-4x = 1x}$

$\text{-13y + 16y = 3y}$

$\text{8 + (-18) = -10}$

$\boxed{\boxed{\bf{Answer: 1x + 3y - 10}}}\checkmark$

Find the gradient of the line passing through (6,8) and (4,10)

Mariulka [41]

Question:

Find the gradient of the line passing through (6,8) and (4,10).

Answer:

-1 is the right answer.

Step-by-step explanation:

Slope of the line = The gradient of the line

Gradient of the line is known as change in the value of y-axis by change in the value of x-axis

Gradient = ∆y\∆x

$Gradient = \frac{y_ 2 - y_1}{x_2 - x_1} = \frac{(10 - 8)}{(4 - 6)} = \frac{(2)}{(- 2)} =\boxed{- 1}\\$

Meenu bought two fans for ₹1200 each. She sold one at a loss of 5% and the other at a profit of 10%. Find the selling price of e

Vinvika [58]

<h3><u>Solution: </u></h3>

Overall<u> </u>CP of each fan = ₹1200 .

One is sold at a loss of 5% .

( This means if CP is ₹100, SP is ₹95 ) .

• Therefore,When CP is ₹1200 , Then SP is ₹ 1140.

$= > \frac{95}{100} \times 1200 = 1140$

Also,Second fan is sold at a profit of 10% .

It means , If CP is ₹100 , SP is ₹110.

Therefore , When CP is ₹1200 , Then SP is ₹1320.

<u>• We need to find the combined CP and SP to say whether there was an overall profit or Loss.</u><u>.</u>

Total CP = ₹ 1200 + ₹ 1200 = ₹ 2400.
Total SP = ₹ 1140 + ₹ 1320 = ₹ 2460.

Since total SP > total CP , A profit of ₹ ( 2460 - 2400 ) or ₹60 has been made ..

<h3>Hope this helps you :)</h3>
