I dont know if this will help you, but a 15th (.15) of an hour is 9 minutes!
So it'd be
.15=9 minutes
.30=18 minutes
.45=27
.60=36
.75=45
.90=54
and obviously
1.0 is 60 minutes
(((EVERY .05 IS THREE MINUTES))))

A grocer has two kinds of tea, one selling for 80 cents per pound and the other selling for 60 cents per pound. How many pounds

ruslelena [56]

X*80+y*60= 50*74
x +y =50 | * ( -60)

80x + 60y= 50*74
-60x - 60y=-50*60
---------------------------
20x= 50*(74-60)=50*14
x=50*14/20=35 pounds of 80 cents tea
y=50-35=15 pounds of 60 cents tea

Help! In parallelogram LMNO below, find the length of MO

pashok25 [27]

Answer:

Step-by-step explanation:

The diagonals of a parallelogram bisect each other.

5y - 8 = 3y + 1 Add 8 to both sides

5y = 3y + 1 + 8 Subtract 3y from both sides

5y - 3y = 9 Combine

2y = 9 Divide by 2

2y/2 =9/2

y = 4. 5

5y - 8 =

5(4.5) - 8 =

22.5 - 8 =

14.5

That represents 1/2 of MO

MO = 2 * 14.5

MO = 29

2. Sketch the graph: 4y – 3x = 12.

goblinko [34]

Answer:

see below

Step-by-step explanation:

A graphing calculator is useful for this.

To find the x-intercept, set y=0 and solve for x:

0 -3x = 12

x = -4 . . . . . . divide by -3

To find the y-intercept, set x=0 and solve for y:

4y - 0 = 12

y = 3 . . . . . . divide by 4

Plot the x- and y-intercepts on their respective axes and draw a line through them.
