Answer:
3
Explanation:
4 is half of 8 on the right side, so that means X has to be half of 6, so it’s 3. Also, it couldn’t be 2 because it is too big, and it can’t be 4 because it isn’t the same length as the other 4, so it’s 3
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

Answer:
1. 1.28
2. 55
3. +
Step-by-step explanation:
1. 0.043 x 10 {3}
= 0.043 x (10 x 3)
= 0.043 x 30
= <u>1.28</u>
2. 5 + (9) (6) - 4
= 5 + 9 x 6 - 4
= 5 + 54 - 4
= 59 - 4
= <u>55</u>
3. Which of the these operations should be completed last when solvingan equation?
a. x
b. +
c. ()
d.÷
<u>b. +</u>
