four tanks each had 54 litres and 750ml. what is their total capacity in litres ​

Answers

Answer: 219 I beleive

Step-by-step explanation: 54(4)+(.750)4=219

Answer:

each tank = 54 + (750÷ 1000) liter = 54.75L

so the capacity of the four tanks = 4x 54.75 = 219litre

Step-by-step explanation:

1) change 750 ml int litre which is equal 750÷1000 = 0.75L

A college student completed some courses worth 3 credits and some
courses worth 4 credits. The student earned a total of 5% credits after
completing 18 courses. How many courses worth 3 credits did the student
complete?
A. 13
B. 5
C. 20
D. 39

Answers

Answer:

A. 13

Step-by-step explanation:

Note: It seems typo in the question. 5% should read 59.

Let 3 credit courses = x, 4 credit courses = y

As per  given we have following equations:

x + y = 183x + 4y = 59

Solve the system by elimination. Multiply the first equation by 4 and subtract the second one:

4(x + y) - (3x + 4y) = 4(18) - 594x + 4y - 3x - 4y = 72 - 59x = 13

The answer is 13

Correct choice is A

I think its A.

the answer is 12.9045.

which is close to 13.

I hope this helps.

Help ASAP

Answers

Answer:

14

Step-by-step explanation:

Answer:

(x, y) = (-16/5, 13[tex]\frac{1}{5}[/tex])

Step-by-step explanation:

4x + 9y = 24

x + y = 10 $\Rightarrow$ x = 10 - y

Substituting the value of x (second equation) into the first equation, we get:

4 * (10 - y) + 9y = 24

40 - 4y + 9y = 24

5y = -16

y = -16/5.

So, x = 10 - (-16/5) = 10 + 3[tex]\frac{1}{5}[/tex] = 13[tex]\frac{1}{5}[/tex]

y = 2x – 1
x + y = 2

Answers

Answer:

x = 1, y = 1

Step-by-step explanation:

plug y = 2x - 1 into the equation x + y = 2:

[tex]x + (2x - 1) = 2\\3x - 1 = 2\\3x = 3\\x = 1[/tex]

plug that into the equation y = 2x - 1

[tex]y = 2*1-1\\y=2-1\\y=1[/tex]
