7th grade math can someone help me

it will be 1 and 7 ok

Step-by-step explanation:

170º and 10º

Step-by-step explanation:

You can setup the equation as 17x + x and then set that equal to 180

so the full equation would look like 17x + x = 180

Then you can simplify it to 18x = 180 and then you just divide 180 by 18 which equals 10

That means that x = 10

So the two measures would be 170 and 10

the 3rd on is correct

step-by-step explanation:

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
