Answer:
4x + 2y = 7
Step-by-step explanation:
The standard form equation goes as follows: Ax + By = C
We know what A, B, and C is so all we need to do is fill them in.
It took Lin's dad about 3.6 miles for him to meet up with his family.
<h3>
Speed</h3>
Speed is the ratio of total distance travelled to total time taken. It is given by:
Speed = distance / time
Let d represent the distance travelled by Lin to meet up with his family. Hence:
Total time for Lin's Dad = d/0.24 + 5
Total time for Lin = d/0.18
Hence:
d/0.24 + 5 = d/0.18
100d/24 + 5 = 100d/18
1800d + 2160 = 2400d
d = 3.6 miles

So here you're using system of equations. You can solve systems by graphing, elimination, or substitution. Ill use substitution. First lets solve for x. take the second equation and add y to both sides to get x by itself:
x - y = 75
x = y + 75 now plug y+75 in for x in the first equation
x + y = 743
(y +75) +y = 743 solve for y
2y +75 = 743 subtract 75
2y = 668 divide both sides by 2
y = 334
now plug this into any of the 2 equations to solve for x i chose the second one
x - y = 75
x - 334 = 75 add 334 to both sides
x = 409
This means x, sold before the tournament is 409 and y, sold at the door is 334. That means the assistant is wrong and accidentally flipped the two answers
14.92*38=566.96
14.92+14.92=29.84*5=149.2
149.2+566.96=716.26
Her total pay was $716.26, hope this helps, have a BLESSED day!
My math is 6%= 0.06*650=39*60 is $2,340 if i am correct please mark as brainliest thx:)
