Answer:
Lee= 20 L per hour.
Garcia = 40L per hour
Step-by-step explanation:
This formula is:
40x + 20y = 2000L
with if being known that x + y = 60.
In this x is the rate for Garcia and y is the rate for Lee.
You can also say that x = 60 - y, which you can fill in.
40 * (60-y) + 20y = 2000
2400 - 40y + 20y = 2000
-20y = -400
y = 20 L per hour.
So x = 60 - 20 = 40L per hour

Answer:240 strands of dough
Step-by-step explanation:
You make a loaf of challah bread by braiding 6 strands of dough together. This means
1 loaf of challah bread requires braiding 6 strands of dough together. This is the unit rate for making challah bread.
The number of loaves of bread you can make with 40 strands of dough will be
1 loaf of challah bread requires braiding 6 strands of dough
x loaves of challah bread will require braiding 40 strands of dough
x = 40 × 6 = 240 strands of dough
Using the equilateral triangles, the hexagon shaped design will use 6 triangles.
Solve first for the area of the triangle using the formula.
Area of the triangle= sqrt3/4s^2
= 6.93 cm^2
Total area of the hexagon = 6 x area of the triangle
= 41.57 cm^2
