Answer:

x = - 5 , y = 0

Step-by-step explanation:

- 4x + 7y = 20 → (1)

y = 3x + 15 → (2)

Substitute y = 3x + 15 into (1)

- 4x + 7(3x + 15) = 20 ← distribute parenthesis and simplify left side

- 4x + 21x + 105 = 20

17x + 105 = 20 ( subtract 105 from both sides )

17x = - 85 ( divide both sides by 17 )

x = - 5

Substitute x = - 5 into (2)

y = 3(- 5) + 15 = - 15 + 15 = 0

Then x = - 5 , y = 0 is the solution to the system

aev [14]

Answer:

51t^3

Step-by-step explanation:

64+3=67

67 +(-16)=51

t^2 +t= t^3

now you just add them up but they cant be combined because one is a number and the other a variable w an exponent so we just get 51t^3

The set for a school play needs a replica of a historic building painted on a backdrop that is 20 feet long and 16 feet high. Th
expeople1 [14]

Answer:

Stage crewmember's calculation is incorrect

Correct = 1/16x 1/16y

Step-by-step explanation:

Given that:

Dimension of backdrop : 20 feets long ; 16 feets high

Actual dimension of building : 320 feets long ; 256 feets high

The correct scale factor can be obtained thus :

Ratio of backdrop dimension to the actual dimension of building

Length : 20 / 320 = 1 /16

Height : 16 / 256 = 1/16

Hence, stage crewmember's calculation of (1/20x ; 1/20y) is incorrect.
