U ALGEBRA Evaluate each expression if x = 2.1, y = 0.031, and z = 3.05
22. xy + 2
23. y + x2

22.) 2.0651

23.) 4.231

Step-by-step explanation:

22.) Substitute values into equation

(x)(y) + 2 =

(2.1)(0.031) + 2 = 2.0651

23.) Substitute values into equation

(y) + (x)2

(0.031) + (2.1)2 = 4.231

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
