For number 3.

You add 8 to both sides as you need to separate the variable

4x-8=32
+8 +8

4x=32

now divide 32 by 4

x=8

for number 4

you use pemdas to multiply the parenthisis

2(x-5)=-20

(2•x)-(2•5)

2x-10=-20

then add 10 to both sides

2x-10=-20
+10 +10

2x=10

divide 10 by two

x=5

Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were all

Art [367]

Nathan has an infection and he needs to be treated with penicillin
But there’s a 75% probability of him being allergic to penicillin
And to test if the skin reacts to penicillin, the test is 98% accuracy
So even if he has the allergy the test is only 98% accurate of identifying the allergy
Therefore we are asked to find the probability of both these events happening
Event 1 and event 2 both should happen then. When the ‘and’ function is used in probabilities then the probabilities of both events happening should be multiplied
Therefore probability that Nathan has the allergy and test predicts it is
= 75% x 98% = 0.735
The answer is D. 0.735

<h3>Answer 1a :- </h3>

Here we can solve this question using<em> </em><em>Unitary</em><em> </em><em>Method</em><em> </em><em>.</em> As ;

→ In 17hrs the boat travels 452km

→ In 1hr the boat will travel 452km/17

→ In 9hrs the boat will travel 452/17km * 9 = 239.29km

$\rule{200}4$

<h3>Answer 1b:-</h3>

→ A car can travel 156km on 13L gasoline .

→ It will travel 1km on 13/156L of gasoline .

→ It will travel 480km on 13/156*480L = 40L of gasoline .

$\rule{200}4$

<h3>Answer 2a :-</h3>

→ A boat can go 180 miles on 60L gasoline.

→ It will go 1mile in 60/180L of gasoline.

→ It will go 306 miles in 60/180*306L = 102L of gasoline .

$\rule{200}4$

<h3>Answer 2b :-</h3>

→ On 51L of gasoline a car can go 408km

→ On 1L of gasoline car will go 408/51 km

→ On 11L of gasoline it will go 408/51*11L = 88km

$\rule{200}4$
