Answer:
(1) 9n = 56
<u>n = 6</u>
(2) 10 + 4y = 38
<u>y = 7</u>
(3) 3x + 8x = 55
<u>x = 5</u>
(4) 6m + 20 = 8
<u>m= -2</u>
(5) 17 - 3a = 23
<u>a = -2</u>
(6) 10x + 4 = 6x + 16
<u>x = 3</u>
(7) 4(x - 2) + x = 17
<u>x = 5</u>
(8) 2(x + 3) + 3x = x + 22
<u>x = 4</u>
(9) <u>D. 10</u>
(10) -2(3x - 2.4) = 3(3x - 2.4)
im not sure about this equation

Answer:
x=5
Step-by-step explanation:
So how i came about to get this answer, was
y=15-3x
y=15-3(5)
y=15-15
y=0
I found five by testing out different numbers for x such as 1 2 3 4, but when i got to five, that was where i got the answer, as shown above.

Answer:
The other number is 330
Step-by-step explanation:
The computation of the other number is shown below:
As we know that
HCF × LCM = Product of Two Numbers
So,
30 × 2310 = 210 × other number
Now
The other number is
= (30 × 2310) ÷ 210
= 330
hence, the other number is 330 and the same is to be considered
We simply applied the above formula so that the correct answer could come
Step-by-step explanation:
Put the interior angle equal to 180.
It would look something like this:
x+45=180
-45 -45
180-45= 135 so the exterior angle would be 135!
