15/4
Step-by-step explanation:
to isolate x you must divide 4/15 on both sides
to divide by fractions, multiply by the reciprocal.
the reciprocal of 4/15 is 15/4, so 15/4 is multiplied on both sides

I'd say its 39 degrees, not much to go off from other than the straight line would equal 180
Answer:

Step-by-step explanation:
x + 141° = 180° (co interior angles are equal)
x = 180° - 141°
x = 39°

The ratio of Maggie's age now to her brother Steven's age now is 2:3. In ten years, the ratio of their ages will be 4:5. How old in Maggie now? Do not label years old in your answer.
Answer: Maggie is currently 10 years old.
====================================================
Explanation:
M = Maggie's age today
S = Steven's age today
The ratio of their current ages, specifically Maggie's age to Stevens age, is 2:3. So 2/3 = M/S
We can cross multiply to get 2S = 3M and divide both sides by 2 getting S = 3M/2 = 1.5M
So whatever Maggie's age is, we multiply by 1.5 to get Steven's age. This only applies to their current present day ages.
----------------------
In 10 years, Maggie will be M+10 years old and Steven will be S+10 years old.
The ratio of their ages at this point in time is 4:5, so,
4/5 = (M+10)/(S+10)
4(S+10) = 5(M+10) ..... cross multiply
4S+40 = 5M+50
4S-5M = 50-40
4S-5M = 10
4(1.5M) - 5M = 10 .... plug in S = 1.5M
6M - 5M = 10
M = 10
Maggie is currently 10 years old.
----------------------
Extra info:
Use the value of M to find S.
S = 1.5*M
S = 1.5*10
S = 15
So Steven is currently 15 years old.
The ratio of Maggie's current age to Steven's current age is M/S = 10/15 = 2/3 which turns into 2:3
In 10 years, Maggie will be M+10 = 10+10 = 20 and Steven will be S+10 = 15+10 = 25
The ratio of their ages now is (M+10)/(S+10) = 20/25 = 4/5 leading to the ratio 4:5
This confirms our answers.

How old are my daughters?” The guests went outside to look at the house number. They thought for a few minutes, and then said, “This riddle can’t be solved!” The mathematician said, “Oh yes, I forgot to tell you the last clue. My youngest daughter prefers strawberry ice cream.” With this last clue, the guests could solve the riddle. How old are the mathematician’s daughters?
Answer:

What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Miguel and his brother Ario are both standing 3 meters from one side of a 25-meter pool when they decide to race. Miguel offers Ario a head start. Miguel says he will start when the ratio of Ario's completed meters to Ario's remaining meters is 1:4.
The formula for the calculation is given as,
x = ( m ) / ( m + n) ( x₂ - x₁ ) + x₁
x = ( 1 ) / ( 5 ) ( 25 - 3 ) + 3
x = 22 / 5 + 3
x = 4.4 + 3
x = 7.4 meters

In the figure below, lines that appear to be parallel are parallel. Solve for a, b, and c.
Answer:
a = 55
b = 13
c = 8
Step-by-step explanation:
2a - 5 = 105° (alternate exterior angles are congruent)
Add 5 to both sides
2a - 5 + 5 = 105 + 5
2a = 110
Divide both sides by 2
2a/2 = 110/2
a = 55
(2a - 5) + (5b + 10) = 180° (consecutive interior angles/same side interior are supplementary)
Plug in the value of a
2(55) - 5 + 5b + 10 = 180
110 - 5 + 5b + 10 = 180
Add like terms
115 + 5b = 180
Subtract 115 from each side
115 + 5b - 115 = 180 - 115
5b = 65
Divide both sides by
5b/5 = 65/5
b = 13
10c - 5 = 5b + 10 (corresponding angles are congruent)
Plug in the value of b
10c - 5 = 5(13) + 10
10c - 5 = 65 + 10
10c - 5 = 75
Add 5 to both sides
10c - 5 + 5 = 75 + 5
10c = 80
Divide both sides by 10
10c/10 = 80/10
c = 8
