Answer: 8.75
Step-by-step explanation:
Let walking rate = x
Riding rate = x + 10
Time taken to ride 30km = time taken to walk 14 km
Time = distance / speed
Hence,
30/ (x + 10) = 14 / x
Cross multiply :
30x = 14( x + 10)
30x = 14x + 140
30x - 14x = 140
16x = 140
x = 140 / 16
x = 8.75
Walking rate = 8.75 kph
What is the slope of any line parallel to the graph of y = 8x + 20?
Answer:y=mx+b
m=slope
Step-by-step explanation:
the slope is 8
The slope of line is 8.
Given that,
Graph is y = 8x + 20We need to find the slope of line.According to the scenario, calculation of data are as follows,
Formula for slope of parallel line is as follows,
y = mx + b ( where m = slope)
So, by comparing both equations we get,
m = 8
or slope of line = 8

Answer: Lunch:$16 Coffee: $4 Julie had $12 left.
Step-by-step explanation:
Answer:
1. Lunch ($16)
2. Coffee ($4)
3. how much money did she have left?
she had ($12) left
Step-by-step explanation:
1. To get the amount of money she used on lunch you have to look at the word problem it says "she spent 1/2 of her money on lunch" her total is $32 dollars and 1/2 is .5 as a decimal and 50% as a percentage so 50% of 32 is (16) so she spent $16 dollars on lunch alone.
2. To find how much money she used on Coffee you need to read the context of the problem its asking for "how much did she use of the money that is left from her lunch" so she has $16 dollars she used from lunch so now it wants you to find 1/4 of $16 dollars or 25% of 16 and 25% of 16 is (4)
so she spent 4 dollars of what was left so the answer is 4.
3. To find how much is left add up 16 and 4 and you get 20 then subtract it by the original number which is 32 so it should look like this 32 - 20 = 12
so the money she has left is $12 dollars.

What is the slope of the line? Please explain your answer.
A.) m=5
B.) m= -5
C.) m=1/5
D.) m= -1/5
Answer: D
Step-by-step explanation: Assuming the left point is A at (-2,2) and the right point is B at (3,1) we can determine the slope by using the “Rise over Run” rule where the change in Y is the “Rise” and the change in X is the “Run”. By setting up the equation y2-y1/x2-x1 we can plug in the coordinates from the variables and get 1-2/3+2 which leaves us with our answer m= -1/5

A side of the triangle below has been extended to form an exterior angle of 156°. Find
the value of x
Answer:
x=24
Step-by-step explanation:
again 180-156=24
super easy remember exterior +interior angles add up to 180
Brainliest please
First angle = 105
Second angle = x
Third angle = 156 - 105
= 51
_________________________________________
Three angles of the triangle:
[tex]105[/tex]
[tex]x[/tex]
[tex]51[/tex]
___________________________________________
Angle sum of triangle = 180°
[tex]105 + 51 + x = 180[/tex]
[tex]156 + x = 180[/tex]
[tex]x = 180 - 156[/tex]
[tex]x = 24[/tex]
3/5 divided by 2 1/2
Step-by-step explanation: To divide mixed numbers, first rewrite the mixed numbers as improper fractions.
So here, 3/5 is already a fraction and 2 and 1/2 can be written as 5/2.
Remember that dividing by a fractions means the same thing
as multiplying by the reciprocal of that fraction.
In other words, 3/5 ÷ 5/2 can be rewritten as 3/5 · 2/5.
Finally, multiplying across the numerators and the
denominators, we have 6/25.
The result of the division of 3/5 divided by 2 1/2 is: 6/25.
Here, we have,
