Given:
Total amount of Mingfa and her sister = $130
If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.
To find:
How much money does Mingfa actually have?
Solution:
Let, Mingfa have $x and her sister has $y initially. Then,
...(i)
If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.
...(ii)
Substitute the value of x from (ii) in (i).
Divide both sides by 4.
Putting in (i), we get
Therefore, Mingfa have $95.
Answer:
I think that some information is missing? what is the slope?
If you are trying to say that there is NO SLOPE then the
answer is " x = 4 "
Step-by-step explanation:
11/30 - 6/30 - 5/30 = 0
The answer is 0
Answer:
B. 12 + 2pi cm
Step-by-step explanation:
The shaded region is made up of 3 square sides and one half circle. The three square sides are each 4, which means that those altogether equal 12.
The circle's circumference can be found by using the equation c = (d)pi
The diameter is 4, so the whole circumference is 4pi. However, you only need half of a circle, which is represented by 2pi.
Add them all together, and you get 12 + 2pi cm.
Answer: 24
Step-by-step explanation:
Let the number of defeats be represented by x.
Since the total number of victories exceeds the number of defeats by 4, then the number of victories will be:
= x + 4
We then add the number of victories and losses together and equate them to 44. This will be:
x + x + 4 = 44
2x + 4 = 44
2x = 44 - 4
2x = 40
x = 40/2
x = 20
Therefore number of victories will be:
= x + 4
= 20 + 4
= 24
