5(2x – 3) = 5 Part A: How many solutions does this equation have? (4 points) Part B: What are the solutions to this equation? Sh
Maru [420]

ANSWER

a) One Solution

b) the solution is x=2

EXPLANATION

The given equation is:

5(2x - 3) = 5

We expand to get;

10x - 15 = 5

Group similar terms;

10x = 15 + 5

This implies that,

10x = 20

Divide both sides by 10 to obtain,

x = 2

Help pls!! Whoever answers gets marked brainliest
Tamiku [17]

Answer:

10. x= 10 y=sqrt 200

11. x=y=450

12. x=19 y=sqrt 1083

13. x=sqrt 48 y=sqrt 12

Step-by-step explanation:

10.

x and 10 are the same

10^2+10^2=200

sqrt 200 is not a whole number so y is just sqrt 200

11.

30^2=2x^2 because x and y are the same

x^2=450

sqrt 450 is not a whole number so x and y are just sqrt 450

12.

x= 38 divided by 2=19

38^2=19^2+y^2

1444=361+y^2

y^2=1083

sqrt 1083 is not a whole number so y is just sqrt 1083

13.

x^2=(x/2)^2+36=x^2/4+36

x^2=48

sqrt 48 is not a whole number so x is just sqrt 48

y is half of x so it is sqrt 12

The cost of two tables and three chairs is $705. If the table costs $40 more than the chair,find the cost of the table and the c
Nadusha1986 [10]

Answer:

the cost of the table is \$165

the cost of the chair is \$125

Step-by-step explanation:

Let

x-----> the cost of the table

y----> the cost of the chair

we know that

2x+3y=705 -----> equation A

x=y+40 -----> equation B

substitute equation B in equation A

2(y+40)+3y=705

2y+80+3y=705

5y=705-80

y=625/5

y=\$125

Find the value of x

x=y+40  ----> x=125+40=\$165
