Answer:

D

Step-by-step explanation:

Amy spent 1/6 of the 90 dollars on school supplies, which means to multiply 1/6 by 90

1/6*90

6 and 90 are both factors of 3, so cancel

1/2*30

30/2

$15

Answer is D

PS. you can put the fraction 15/90 and see that it is equal to 1/6 if you're not sure/ if you want to double check :)

A bottle holds 3 pints of lemonade. How much is this in fluid ounces?
Hatshy [7]

Answer:

48 fl oz

Can someone please help me! I'll give brainliest to who ever answers first with a positive answer
Effectus [21]

1. 3(p+q)=p

3p+3q=p; 3p-p=3q; 2p=q so p=q/2


2. 4a=2b-7

2b=4a+7 so b=(4a+7)/2

when a=3 , b=(12+7)/2=19/2=9.5


3. d=rt; r=d/t

4.( 2x15)+(2xwidth)=90

2x width=90-30

width =60/2=30

miss Akunina [59]
20100 = 16000 * (1.02)^ t

20100/16000 = 1.02^t

1.25625 = 1.02^t

log 1.25625 = t * log 1.02

t = log 1.25625 / log 1.02

Simplify 3×+1(2×-1)2-1(6×)​

Hi my lil bunny!

❧⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯☙

Answer =   \boxed {x - 2}

3x +1(2x-1)2-1(6x)

= \boxed {3x + 1 . ( 2x - 1 ) . 2 - 1 (6x) = x - 2}

Steps :

3x + 1 . (2x - 1) . 2 - 1 . (6x)

Remove the parentheses : (a) = a

= 3x + 1 * (2x- 1) * 2 - 1 * 6x

Multiply the numbers : 1 * 2 = 2

= 3x + 2 ( 2x - 1 ) * 6x

Multiply the numbers : 1 * 6 = 6

= 3x + 2 ( 2x - 1 ) -6x

Expand: 2 (2x - 1) :   4x - 2

2 ( 2x - 1 )

Apply the distributive law : a (b - c) = ab - ac

a = 2, b = 2x, c = 1 \\= 2 * 2x - 2 * 1

Simplify 2 * 2x - 2 * 1 : 4x - 2

= = 4x - 2

= 3x + 4x - 2 - 6x

Simplify 3x + 4x - 2 - 6x : x - 2

= x - 2
