Answer:
C
Step-by-step explanation:
y=mx+n m is slope if slopes are perpendicular m1.m2=-1
(2/3) . (-3/2) = -1
m1=2/3
m2=-3/2
y=(2/3)x-3 m=2/3 n= -3
y=(-3/2)x+2 m = -3/2 n = 2
Answer:
65min.
Step-by-step explanation:
45min. is 20min. less than _______
45 = x - 20
x = 45 + 20
x = 65
6 is 61
5 and 7 are 119 (180 - 61)
4 and 2 are 61
1 and 3 are 119
0.4 x 25. this will give you 10
Each digit of each amount is written in expanded form depending on the position of the digit.
Let's see number 4.875.
Digit 4 is in the place of the units so it is 4 * 1
8 is in the place of the tenths, so it is 8/10 = 8 * 1/10
7 is in the place of the hundreths, so it is 7/100 = 7 * 1 /100
5 is in the place of the thousanths, so it is 5/1000 = 5 * 1 / 1000
So, the number 4.875 written in expanded form using fractions is:
4*1 + 8 * 1/10 + 7 * 1/100 + 5 * 1/100.
Now, see the next amount, 3.125, which using the same procedure leads to:
3 *1 + 1 * 1/10 + 2 * 1/100 + 5 * 1/ 1000
