Geraldine has 8 cups of sugar. She uses 6 3/5 cups to make a large cake. How many cups of sugar does she have left?

Inga [223]

Answer:

$1\frac{2}{5}$

Step-by-step explanation:

remaining cups = total cups - used caps

let remaining cups be = x

total cups = y = 8

used cups = z= $6\frac{3}{5}$

Hence x = y-z

x = 8 - $6\frac{3}{5}$

= $\frac{8}{1}$ - $\frac{33}{5}$ = $\frac{40-33}{5}$ = $\frac{7}{5}$ = $1\frac{2}{5}$

x= $1\frac{2}{5}$

Remaining cups = $1\frac{2}{5}$

Determine the midpoint of each line segment with the given endpoints.

KonstantinChe [14]

Answer:

(-1, 3.5)
(0, 0)
(-3, 0)
(4.5, -3.5)

Step-by-step explanation:

Midpoint Formula

M = (x₁ + x₂ / 2, y₁ + y₂ / 2)

#1 : (-2,5) and (0. 2)

M = (-2 + 0 / 2, 5 + 2 / 2)
M = (-2/2, 7/2)
M = (-1, 7/2)
M = (-1, 3.5)

#2 : (0, 3) and (0, -3)

M = (0 + 0 / 2, 3 - 3 / 2)
M = (0, 0)

#3 : (-2, 0) and (-4, 0)

M = (-2 - 4 / 2, 0 + 0 / 2)
M = (-6/2, 0)
M = (-3, 0)

#4 : (9, 0) and (0, -7)

M = (9 + 0 / 2, 0 - 7 / 2)
M = (9/2, -7/2)
M = (4.5, -3.5)
