Emiko needs to go to the dentist. It takes her 65minutes to get there by riding her bike. This is 5 minutes shorter than twice the time it would takeby bus. How long does it take Emiko to get to the dentist by bus? a.35 min b.40 min c.45 min d.50 min I will brainliest

Answers

65 min by riding her bike

x min by boarding a bus

since the time taken to get to the dentist with a bus is 5min shorter than twice the time taken with a bike, it can be written as

(2x) - 5 = 65

2x = 65 + 5

2x = 70

x = 35 min. (A)

What is the equation of the line that passes through the point (3,-2) and has a
slope of -22

Answers

Answer:

y = -2x + 4

Step-by-step explanation:

slope intercept form:

y = mx + b

m = slope = -2

b = y-intercept

x = x = 3

y = y = -2

Plug in the corresponding numbers to the corresponding variables:

-2 = (-2) * (3) + b

Simplify. First, multiply:

-2 = (-6) + b

Next, isolate the b. Note the equal sign, what you do to one side, you do to the other. Add 6 to both sides of the equation:

-2 (+6) = -6 (+6) + b

b = -2 + 6

b = 4

Plug in 4 for b in the equation:

y = mx + b

y = -2x + 4

~

the equation is now solved for y = 1/2x-5

Answers

Answer:

slope: 1/2

If 50 people can fit into 6 rooms. How many people
fit into 42 rooms?

Answers

Answer:

350 people can fit into 42 rooms

Step-by-step explanation:

So we can write it as a relation fraction equation:

[tex]\frac{50}{6}=\frac{x}{42}[/tex]

Where:

x represents the people can fit in 42 rooms

[tex]x=\frac{50*42}{6}[/tex]

[tex]x=350[/tex]

Therefore, 350 people can fit into 42 rooms.

solve 35% of 84 using the mental method

Answers

Answer:

29 approximately

Step-by-step explanation:

You want to estimate 35% of 84.  35% is roughly equivalent to 1/3, so multiply 84 by 1/3 (or, equivalently, divide 84 by 3), obtaining 28.    Use a calculator to find 0.35(84):  29.4.     This 28 is a fairly good estimate of 35% of 84 which is 29.4.
