Answer:

solution of the given system of equation is (4,7)

C is the correct option.

Step-by-step explanation:

The given system of equations is

2x+3y=29...(i)\\\\x=4...(ii)

Substituting the value of x from (ii) in equation (i)

2\cdot4+3y=29\\\\8+3y=29\\\\3y=21\\\\y=7

Therefore, the solution of the given system of equation is (4,7)

C is the correct option.

A party rental company has chairs and tables for rent. The total cost to rent
Tema [17]
2c+5t=43

c=(43-5t)/2

8c+3t=36 and using c found above in this equation gives you:

4(43-5t)+3t=36

172-20t+3t=36

-17t=-136

t=8, and since c=(43-5t)/2

c=1.5

So a table costs $8.00 to rent and a chair costs $1.50

Sergeu [11.5K]
Let p = pictures only
let f = pictures with frames

p + f = 100
5p + 10f = 875

Solve for one variable in the first equation then plug into the second

p = 100 - f
5(100 - f) + 10f = 875
500 - 5f + 10f = 875
500 + 5f = 875
5f = 375
f = 75

75 pictures with frames were sold

tiny-mole [99]

Complete question :

The sugar maple tree in Joshua's yard is 1/4 the age of the oak tree in his yard. The sugar maple tree is 20 years old. How old is the oak tree?

Answer:

80 years

Step-by-step explanation:

Given that :

Sugar maple tree = 1/4 age of oak tree

Age of sugar maple tree = 20

Age of oak tree = x

20 = 1/4 * x

20 = x / 4

Multiply both sides by 4

20 * 4 = (x / 4) * 4

80 = x

Hence, Age of oak tree = 80 years
