Answer:

C = -6

Step-by-step explanation:

C = [2×1/4 + 1] ÷ [3×1/4 -1 ]

C = 3/2 ÷ -1/4

C = 3/2 × -4 = -6

C = 2d + 1 / 3d - 1

So, d = ( C + 1 ) / ( 3C - 2 )

PLS HELP ME ILL MARK BRAINLIST IF SOMEONE CAN HELP ME WITH THESE 2 QUESTIONS!!

Nat2105 [25]

Answer:

1. Andrew grew 4 5/12 inches in 2 years

2. Abbey rode her bike for 3 3/8 hours in 2 days.

Step-by-step explanation:

When adding fractions you must have a common denominator for both of them.

First make the mixed fraction, improper fractions.

1 3/4 = 7/4

2 2/3 = 8/3

7/4 x 3/3 = 21/12

8/3 x 4/4 = 32/12

21 + 32 = 53

53/12 = 4 5/12

1 3/4 = 7/4

1 5/8 = 13/8

7/4 x 4/4 = 28/16

13/8 x 2/2 = 26/16

26 + 28 = 54

54/16 = 3 3/8

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

Sam can mow a lawn in 30 minutes. Rocky can mow the same lawn in 90 minutes. How long does it take for both Sam and Rocky to mow

Anvisha [2.4K]

Answer:

$\frac{45}{2} \ minutes$

Step-by-step explanation:

Given:

Sam can mow a lawn in 30 minutes.

Rocky can mow the same lawn in 90 minutes.

Question asked:

How long does it take for both Sam and Rocky to mow the lawn if they are working together?

Solution:

By unitary method:

<u>For Sam</u>

Sam can mow in 30 minutes = 1 lawn

Sam can mow in 1 minute = $\frac{1}{30}\ lawn$

<u>For Rocky</u>

Rocky can mow in 90 minutes = 1 lawn

Rocky can mow in 1 minutes = $\frac{1}{90} \ lawn$

In a case of working together:

In 1 minute, both will mow = $\frac{1}{30}\ lawn$ + $\frac{1}{90} \ lawn$

= $\frac{3+1}{90} = \frac{4}{90} \ lawn$

To mow $\frac{4}{90} \ lawn$ together, it takes = 1 minute

So, to mow 1 lawn together, it takes = $\frac{1}{\frac{4}{90} } =\frac{90}{4} =\frac{45}{2} \ minutes$

Thus, both Sam and Rocky will mow the lawn together in $\frac{45}{2} \ minutes$

Lyrx [107]

20 percent of 100 is 20 so the dress is 80 on sale so you need 20 which is 25% of 80
20 plus 80 equal 100 the starting price
25%
