Let A =1 -3 2-2 5 -13 -4 -8and b =b1b2b3Determine if the equation Ax = b is consistent for all possible b1, b2, b3. If the equation is notconsistent for all possible b1, b2, b3, give a description of the set of all b for which the equation isconsistent (i. e., a condition which must be satisfied by b1, b2, b3). What can you use this systemfor?A) Equation is consistent for all b1, b2, b3 satisfying 2b1 + b2 = 0.B) Equation is consistent for all b1, b2, b3 satisfying -3b1 + b3 = 0.C) Equation is consistent for all possible b1, b2, b3.D) Equation is consistent for all b1, b2, b3 satisfying 7b1 + 5b2 + b3 = 0.

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04

step-by-step explanation:

they used 313 gallons of paint

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.
