3. Ivan has completed 45% of his walk.
He has already walked 9 km. How much farther does he have left to walk?
Answer:
11
Step-by-step explanation:
The required distance left to the walk will be 11 km.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
Let the total distance of the walk would be x km
As per the given information, the required solution would be as:
⇒ 45% of x = 9
45% is expressed as 45/100 in fractional form
⇒ (45/100)x = 9
45/100 is expressed as 0.45 in decimal form
⇒ 0.45x = 9
⇒ x = 9/0.45
⇒ x = 20
So the total distance of the walk is 20 km
Since he has already walked 9 km.
So, he has left to the distance of the walk = 20 - 9 = 11 km
Therefore, the required distance left to the walk will be 11 km.

A recipe calls for 1/2 cup of milk for every 3/4 cups of flour. How much milk is required for every cup of flour. *
Answer:
2/3rds
Step-by-step explanation:
for 1 cup of flour you multiply 3/4th by 4 then devide by 3 giving you one cup of flour, now to keep it balanced you do the same to the milk, thus multiplying 1/2 by 4 then dividing it by three, which is 2, you then divide 2 by 3 giving you yours answer, 2/3rds
Answer:
A recipe calls for 1/2 cup of milk for every 3/4 cups of flour. How much milk is required for every cup of flour. *
Step-by-step explanation:
So for every 1/2 a cup is 3/4 cups of flour so if you need to know how much cups of flour is used for 1 total cup of milk you have to add you multiply it is optional if you add put the two fractions next to each other you need to add to the side witch the numbers are 3 so 3+3 is 6 so you got the answer just put the number 4 under the 6 and it will be 6/4 or you could say 1 2/4 or 1 1/2 .
How do I solve this with substitution, can you please put the work and steps. (x,y)
y=x+2
3x+3y=6
Answer:
(0,2)
x=0
y=2
Step-by-step explanation:
We know that y=x+2
This means that we can subsitute this for y into the second equation
3x+3(x+2)=6
This is easy to solve
3x+3x+6=6
6x=0
x=0
We can then use this value for x in the second equation
y=0+2
y=2
I doubled checked this answer on desmos and my math is correct
Answer:
Answer:
(0,2)
x=0
y=2
Step-by-step explanation:
We know that y=x+2
This means that we can subsitute this for y into the second equation
3x+3(x+2)=6
This is easy to solve
Step 1:
3x + 3x + 6 = 6
Step 2:
6x=0
6 6
x=0
Then you should substitute y =x + 2 with the given solution from the first equation, x = 0
y=0 + 2
y=2
Your answer should be, x =0 and y = 2 or (0,2)

8 (5 + 4n) + 11 = -5 (3 - 7n)
Answer:
n=1
Step-by-step explanation:
(5 + 4n) + 11 = -5 (3 - 7n)
5+4n+11=−5(3−7n)
simplify
4n+16=−5(3−7n)
expand
4n+16=−15+35n
regroup
4n+16=35n−15
subtract
16=35n−15−4n
simplify
16=31n−15
add
16+15=31n
simplify
31=31n
n=1
Hope this helps :)
(pls mark brainliest)
Answer:
n=22
Step-by-step explanation:
8 (5 + 4n) + 11 = -5 (3 - 7n)
distribute
=> 40+32n+11=-15+45n
add like terms
=> 51+32n=-15+35n
subtract 35n on both sides and subtract 51 on both sides
32n-35n=-15-51
add like terms
-3n=-66
divide both sides by -3
n=22

The sum of three consecutive even integers is 486. Find all three integers.
Answer:
161 + 162 + 163 = 486
Step-by-step explanation:
(X) + (X + 1) + (X + 2) = 486
X + X + 1 + X + 2 = 486
3X + 3 = 486
3X + 3 - 3 = 486 - 3
3X = 483
3X/3 = 483/3
X = 161

In the figure, BP = BQ and PC = QA. Which of the following postulates prove AB = BC?
Answer:
Option C
Step-by-step explanation:
Segment addition postulate states that "if a point Q lies on a segment joining two points A and B, then AQ + BQ = AB"
By this postulate,
AQ + BQ = AB
BP + PC = BC
Since, BP ≅ BQ and PC ≅ QA
Therefore, BP + PC ≅ BQ + QA
BC ≅ AB
Option (C) will be the answer.
Answer:
Segment Addition Postulate
