Answer:
11/20
Step-by-step explanation:
Answer:
21/7= 3
Step-by-step explanation:
28x + 44y = 964.40
21x + 33y = 723.30
Let's multiply the first equation by 4 and the second by -4
84x + 176y = 3857.6
-84x - 132y = -2893.2
Add the equations together.
0 + 44y = 964.4
Simplify
44y = 964.4
Divide both sides by 44
y = 964.4/44
Since we have the value of y, let's plug 964.4/44 into y for the first equation.
28x + 44(964.4/44) = 964.40
Simplify the left side
28x + 964.4 = 964.4
Subtract 964.4 from both sides
28x = 0
Divide both sides by 0
x = 0
In conclusion,
y = 964.4/44
x = 0
Equation= x divided by -9 = -16
solve= 9 x 16 = 144
answer is 144
Answer:
x = 5
Step-by-step explanation:
This is a simple equation if you look at it right and don't get scared by the "x."
All we need to do is figure out what times 3 = 27. We can do this easily by diving 27 by 3.
27 ÷ 3 = 9
Since our "equation" is 3(x + 4) = 27 we know whatever is in the parenthesis () has to equal to 9. We already get 4 so:
5 + 4 = 9.
3 times 9 = 27.
5 is your answer.

PS if you could mark brainliest that'd be great! I'm very close the "expert" rank. Haha, sorry I usually don't ask.
