Step-by-step explanation:

Step 1:

Let the given expression in word form be expressed as

$(-12)/(3(-8 + ((-4)(2)) - 6) + 2)$

Step 2:

Let us we simplify it using BODMAS rule.

(-12)/ ( 3(-8-8-6) + 2)

(-12) / (3(-22)+2)

1/2(a+b)-(a-b)exponent2 when a=18 and b=14

lora16 [44]

Answer:

Step-by-step explanation:

Substitute the given values for a and b into the expression

$\frac{1}{2}$ (18 + 14) - (18 - 14)²

= $\frac{1}{2}$ × 32 - 4²

= 16 - 16

= 0

Two trains leave New York at the same time heading in opposite directions. Train A travels at 4/5 the speed of train one. After

grandymaker [24]

<h3>Answer: </h3><h3>speed of train A = 44 mph</h3>

=============================================

Work Shown:

x = speed of train A

y = speed of train B

"train A travels 4/5 the speed of train B" (I'm assuming "train one" is supposed to read "train B"). So this means x = (4/5)y

distance = rate*time

d = x*7

d = (4/5)y*7 = (28/5)y represents the distance train A travels

d = y*7 = 7y represents the distance train B travels

summing those distances will give us 693

(28/5)y + 7y = 693

5*( (28/5)y + 7y ) = 5*693

28y + 35y = 3465

63y = 3465

y = 3465/63

y = 55

Train B's speed is 55 mph

4/5 of that is (4/5)y = (4/5)*55 = 4*11 = 44 mph

Train A's speed is 44 mph

Bill Mason is considering two job offers. Job 1 pays a salary of $41,300 with $5,525 of nontaxable employee benefits. Job 2 pays

kupik [55]

Answer:

To Calculate the monetary value of both jobs, you would have to calculate the percent tax rate of each salary and add the nontaxable benefit after taxes.

Step-by-step explanation:

Reminder: since the 25% is a tax rate which we need to <u>subtract</u> from the salary, 75% would be what is left over from the salary after taxes.

<u>Job 1:</u> Job 1 pays a salary of $41,000 and $5,525 of nontaxable benefits. So we calculate the 75% that is left after taxes and add the benefits afterwards.

$(41,000 * 0.75) + 5,525 = 36,275$

<em><u>So the monetary value of Job 1 would be $36,275</u></em>

<u>Job 2:</u> Job 2 pays a salary of $40,400 and $7,125 of nontaxable benefits. So we calculate the 75% that is left after taxes and add the benefits afterwards.

$(40,400*0.75) + 7,125 = 37,425$

<em><u>So the monetary value of Job 2 would be $37,425</u></em>
