6.4x + 3y = 36

x = 3

6.4(3) + 3y = 36

6.4 * 3 = 19.2

19.2 + 3y = 36

36 - 19.2 = 16.8

19.2 - 19.2 = 0

3y = 16.8

16.8/3 = 5.6

3y/3 = y

y = 5.6

B. 5.6

WILL GIVE BRAINLIST 2 BEST ANSWER
kolezko [41]

Answer:

M

Step-by-step explanation:

We have been given side AB and BC

AB must be 6 as it is between 4 and -2 and that distance is 6 (we have been given no units).

BC must be also 6 as it starts at -4 and ends at 2.

Pythagoras Theorem = a^2 + b^2 = c^2 (^2 means squared)

C is the hypotenuse (longest side) and this is what we are trying to find...

6^2 + 6^2 = 36+36=72

So AC is 72, however we need to square root this to get our final answer.

72 doesn't square easily, so we will use surds. 72 is 36*2 and 36 is a square number hence why...

AC is 6 root 2

Hope this helps!

With procedure please<br> 5(x - 1) = 20 (x - 10)
quester [9]

Answer:

13

Step-by-step explanation:

Opening the brackets, we have

5x – 5 = 20x –200

Collecting like terms, we have:

5x – 20x = –200 + 5

– 15x = –195

Dividing both sides by the coefficient of "x"

–15x/–15 = –195/–15

x = 13
