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
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)

Find the equation of the line that is parallel to the line y=-3x-7 and passes through the point (1,2). Write an equation in slop intercept form
Answer:
y=-3x+5
Step-by-step explanation:
y=-3x-7
slope is -3
parallel lines have the same steepness, they have the same slope. The slopes are equal.
y-y1=m(x-x1)
y-2=-3(x-1)
y-2=-3x+3
y=-3x+3+2
y=-3x+5
solve 35% of 84 using the mental method
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.

The Vincent family played a game of basketball. For each game, Ben kept a record of the number of 2-point baskets he attempted, and the number of 3-point baskets he attempted. After the family played several games, he made a scatter plot of the data using the 2-point shots as the x-variable and the 3-point shots as the y-variable. The scatter plot has a line of best fit with the equation y=1.2x+3.1
Answer:
your answer is The y-intercept represents how many 3-point shots Ben will try to make if he attempts 0 2-point shots.
Step-by-step explanation:
Answer:The y-intercept represents how many 3-point shots Ben will try to make if he attempts 0 2-point shots.

If 50 people can fit into 6 rooms. How many people
fit into 42 rooms?
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.
I hope it helps you!

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

What is the slope of the line? Explain how you calculated the slope in the graph going through the points (-6,-3) and (-2,-8).
Answer:
[tex]\frac{-5}{4}[/tex]
Step-by-step explanation:
Use the slope formula so y2 - y1 / x2 - x1 [the numbers are subscripts]
So -8 - (-3) / -2 - (-6) so -8+3/-2+6, therefore -5/4
A pizza with a diameter of 8 inches costs $10 and a pizza
with a radius of 5 inches costs $12. Which pizza is the
best buy (square inches per dollar)?
Answer:
8 inch is your best buy
Step-by-step explanation:
8inch diameter =10 dollars
5 inch radius = 12 dollars
so if we get each equal to the diameter it should be 10 inch and that would be 24 dollars vs . 8 in for 10 dollars. So best buy would be 8 inch
