Answer:
Distance from Fresno where both cars meet = 210 - 150 = 60 miles
Step-by-step explanation:
let x = distance travelled by A from Sacramento
y = distance travelled by B from Los Angeles
t = time after 12 noon that they meet
x = 50(t + 1)
y = 400 - x = 75(t) or x = 400 - 75t
so: 50(t + 1) = 400 - 75t
50t + 50 = 400 - 75t
50t + 75t = 400 - 50
t = 2,8 hrs
so y = 400 - 75(2.8) = 210 miles from Los Angeles
distance from Fresno where both cars meet = 210 - 150 = 60 miles
David's age: x
Joshua: x + 5
Simon: (x+5) + 4 or x + 9
Simon's age + David's age = 15
(x+9) + (x) = 15
2x = 15 - 9
2x/2 = 6/2
x = 3
The ages of the boys:
David: x = 3 years old
Joshua: 3+5 = 8 years old
Simon: 3+9 = 12 years old

Answer:
Follows are the solution to this question:
Step-by-step explanation:
In point A:
The two-point C and y is given, where C is the scale drawing lengths and y is the actual mural lengths so, the formed equation is:
![\to \frac{c}{y}=\frac{2}{5}](https://tex.z-dn.net/?f=%5Cto%20%5Cfrac%7Bc%7D%7By%7D%3D%5Cfrac%7B2%7D%7B5%7D)
In point C
:
Using the value of the scale:
let 1 feet: 20 feet
therefore the equation is:
![\to \frac{c}{y}=\frac{1}{20}](https://tex.z-dn.net/?f=%5Cto%20%5Cfrac%7Bc%7D%7By%7D%3D%5Cfrac%7B1%7D%7B20%7D)
The size of c will be the length of:
![\to c= \frac{y}{20}\\\\\to c= \frac{8}{20}\\\\\to c= 0.4\\](https://tex.z-dn.net/?f=%5Cto%20c%3D%20%5Cfrac%7By%7D%7B20%7D%5C%5C%5C%5C%5Cto%20c%3D%20%5Cfrac%7B8%7D%7B20%7D%5C%5C%5C%5C%5Cto%20c%3D%200.4%5C%5C)
The diagram c scale width will be:
![\to c= \frac{y}{20}\\\\\to c= \frac{15}{20}\\\\\to c= 0.75\\](https://tex.z-dn.net/?f=%5Cto%20c%3D%20%5Cfrac%7By%7D%7B20%7D%5C%5C%5C%5C%5Cto%20c%3D%20%5Cfrac%7B15%7D%7B20%7D%5C%5C%5C%5C%5Cto%20c%3D%200.75%5C%5C)
