Samantha’s hockey team is fundraising for a trip to Europe! They are aerating lawns to raise money. Aerating lawns is a great se

zmey [24]

Answer:

R = 35l-215

Step-by-step explanation:

total amount they earn = 35l

however, to account for the money used to rent the machines, we have to deduct 215 from the total cost.

hence,

R= 35l-215

total amount they raised = 35(26)-215 = $695

they would lose $215 if they were unable to aerate due to weather conditions

they could avoid this potential loss by checking the weather report before renting the machines

150 - x - 2x = 120 + 2x

Svetach [21]

Answer:

x = 6

Step-by-step explanation:

Step 1: Write equation

150 - x - 2x = 120 + 2x

Step 2: Solve for x

Combine like terms: 150 - 3x = 120 + 2x
Add 3x to both sides: 150 = 120 + 5x
Subtract 120 on both sides: 30 = 5x
Divide both sides by 5: 6 = x
Rewrite: x = 6

Step 3: Check

Plug in x to verify it's a solution.

150 - 6 - 2(6) = 120 + 2(6)

144 - 12 = 120 + 12

132 = 132

Estimated the difference 825 round subtract the rounded numbers 213 rounds to

boyakko [2]

Answer:

600

Step-by-step explanation:

Given,

Numbers are 825 and 213.

If the number are equal or greater than 50 then one number will be rounded up. if the number is less then it will rounded down.

Like in this case 25 and 13 are less than 50 so, they will not rounded up.

825 will be rounded to 800.

213 will be rounded to 200.

Subtraction of number

= 800 - 200 = 600

Prove the following identity sin x(sec x+cscx)= tan x +1

Alexxandr [17]

Answer:

Step-by-step explanation:

________________________________________________________

FACTS TO KNOW BEFORE SOLVING :-

$\sin x = \frac{1}{cosec \: x} \: \: or \: \: cosex \: x = \frac{1}{\sin x}$

$\cos x = \frac{1}{\sec x} \: \:or \: \: \sec x = \frac{1}{\cos x}$

$\tan x = \frac{\sin x}{\cos x}$

________________________________________________________

In the question ,

L.H.S. = $\sin x (\sec x + cosec \: x)$

R.H.S. = $\tan x + 1$

Lets solve L.H.S. first.

$\sin x (\sec x + cosec \: x)$

$=> \sin x( \frac{1}{\cos x} + \frac{1}{\sin x} )$

$=> \frac{\sin x}{\cos x} + \frac{\sin x}{\sin x}$

$=> \tan x + 1$

∴ L.H.S. = R.H.S. (Proved)
