Where would parenthesis need to be placed in the expression to get a value of 44? A
2+32×(5−3)

B
2+(32×5)−3

C
(2+32)×5−3

D
(2+3)2×5−3

one of the options are correct

Step-by-step explanation:

Given the expression 2 + 32*5-3, we are to locate the point where parenthesis will be placed to get 44;

There is no point where we are we are going to put parenthesis to get 44

For Option A :

2+32×(5−3)

= 2+ 32 * 2

According to PEMDAS, multiplication is next in precedence

= 2(32*2)

= 2(64)

= 128

For Option B:

2+(32*5)-3

= 2+160-3

= 162-3

= 159

For Option C:

(2+32) * 5 - 3

= 34 * 5 -3

= 170-3

= 167

For Option D:

(2+3)2*5 - 3

5(2)*5 - 3

10*5 -3

= 50 - 3

= 47

From the expansion, none gave us 44, hence none of the options are correct

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
