Mark can make 303,030 birthday cakes.
If x=-6 then y=54.
If x=-4 then y=51.
If x=-2 then y=48.
If x=0 then y=45.
If x=2 then y=42.
If x=4 then y=39.
If x=6 then y=36.
There are an infinite variety of pairs of numbers for 'x' and 'y'
that can make that equation true.
You can use that equation to draw a line on a graph. Then
EVERY point on the line is a solution to the equation.
'x' and 'y' don't have single values unless you have TWO equations.
Answer:
Supplementary angles; 148°
Step-by-step explanation:
180° - 32° = 148° (supplementary angles)
Length of train : 100
length of bridge : 400
distance covered by the train to cross the bridge : (100 + 400) = 500
time taken by the train to cross : 30
speed = distance / time
speed = 500/30
speed = 16.67 meters per second <===
Answer:
11 hours
Step-by-step explanation:
let he works at first store x hours and at car wash y hours. Then
x+y=25
multiply by 4
4x+4y=100 ...(1)
12x+15y=333
divide by 3
4x+5y=111 ... (2)
(2)-(1) gives
y=111-100=11
