Answer:

<h2>Alexis worked 59 hours, Cindy worked 152 hours and Becca worked 74 hours.</h2>

Step-by-step explanation:

Givens

  • They worked a total of 285 hours.
  • Alexis worked 15 hours less than Becca.
  • Cindy worked 4 more than twice as many hours as Becca.
  • Alexis is A.
  • Cindy is C
  • Becca is B

The expressions that model this problem would be

A+C+B=285

Because all together they work 285 hours.

A=B-15

Because Alexis worked 15 hours less than Becca.

C=4+2B

Because Cindy worked 4 hours more than twice Becca's hours

Now, we replace the last two expression in the first one

B-15+4+2B+B=285\\4B-11=285\\4B=285+11\\B=\frac{296}{4}=74

Then, we replace this value to find others

C=4+2B=4+2(74)=152

A=B-15=74-15=59

Therefore, Alexis worked 59 hours, Cindy worked 152 hours and Becca worked 74 hours.

Delta furnishings received an invoice dated may 10 for a shipment of goods received june 21. The invoice was for a $8400.00 less
djyliett [7]

Answer:

The right solution is:

(a) $1,940

(b) $2,813

Step-by-step explanation:

Given:

Invoice amount

= $8,400

Discount 1

= 33.33%

Discount 2

= 12.5%

So,

The net payable amount will be:

= 8400\times  [1 - \frac{100}{300} ]\times [1 - \frac{12.5}{100} ]

= 8400\times \frac{2}{3}\times 0.875

= 4900 ($)

Now,

(a)

Amount paid will be:

= 2000\times 0.97

= 1940 ($)

Balance still to be paid will be:

= 4900-2000

= 2900 ($)

(b)

Amount paid will be:

= (4900- 2000)\times 0.97

= 2900\times 0.97

= 2813 ($)

Balance still to be paid will be:

= 2000 ($)

Thus the above solution is the appropriate one.

astra-53 [7]

Answer:

the football team drank 10 gallons of water

Step-by-step explanation:

if the football team drank 1/3 less than 15, 1/3 of 15 is 5 so you would then subtract 5 from 15 and you get 10

6x - 2y = 32 4x - 2y = 18​
Elis [28]

Answer:

x = 7

y = 5

Step-by-step explanation:

6x - 2y = 32

4x - 2y = 18

2x = 14

4x - 2y=18

x = 7

4 * 7 - 2y = 18

x = 7

28 - 2y = 18

x = 7

2y = 10

x = 7

y = 5

there is only 1 solution for this equation is (7;5)

Done :))
