Answer:

The 4th option is the correct answer

It will take  19 hours of lesson

Step-by-step explanation:

It is given that,

Ahmets rent a piano for $35 per month.

Also he earn $25 per hour giving piano lessons.

He wants to make profit $440 per month.

<u>To calculate the hours needed for getting profit $440 </u>

Let x be the total hours spending for piano lesson

So he earn $25x in one month

But the expenditure is piano rent $35 per month.

25x = 475

x = 19

Need help please please i need help thanks ​

Answer:

1) 6 balls

Step-by-step explanation:

x = number of balls Elsa can shoot

x + 6 = number of balls Anna can shoot

18 = number of balls together they can shoot

x + (x + 6) = 18

x + x + 6 = 18

2x + 6 = 18

2x = 18 - 6

2x = 12

x = 6

2)2) 20x (3÷ 4)=90 120-90=30 thus left seat has 30 seating capacity.

3)Let x & y be packets of [a] type & [b] type detergent sold

Then 9x +7y =180

Let us say x=7

Then 9*7+7y =180

7y =180–63 = 117

y =117/7=19.2 this will not do as it contains decimal not whole number

Say x=6

Then 9*6 +7y =180

7y=180–54 =126

y =126/7 =18 this is acceptable as it is whole number

Answer: 6 packets of (a) and 18 packets of type (b) were sold to get 180Php

4) 5,6,7 female piglets

Jeanne thinks that x+x is the same as x•x. Is this true? Why? Why not?
NARA [144]
Generally, x <span>• x is accepted to mean "x times x" or "x multiplied by x"

and x+x means "x plus x" or "x added to x"

let's try by subsituting numbers for them
if we can find one case where the statement "x+x is the same as x</span><span>•x" is false, then it is not true


let's try x=4
x+x=x</span><span>•x
4+4=4</span>•<span>4
8=16
false



so it is not true
(x+x is equal to 2x, so therefor if we were to solve 2x=x</span><span>•x, we would get that it is only true for x=2 and x=0)

it is not always true
