This question involves basic arithmetic signs and simplifying of bracket terms.
Mobile number is; 9 6 4 1 2 7 8 1 2 3
a) 2x - 5 = 7
Add 5 to both sides to get;
2x = 12
x = 12/2
x = 6
b) 2(p + 1) = p + 4
Expanding the bracket gives;
2p + 2 = p + 4
Rearranging gives;
2p - p = 4 - 2
p = 2
c) 5(y + 1) = 25
Expanding the bracket gives;
5y + 5 = 25
5y = 25 - 5
5y = 20
y = 20/5
y = 4
d) 5(q –1) + 3q = 10 + 1
Expanding the bracket gives;
5q - 5 + 3q = 11
2q - 5 = 11
add 5 to both sides to get;
2q = 16
q = 16/2
q = 8
Question E and F are not clear but as it is r and z that are yet to be gotten, i have gotten the right equations from the brainly link at the end of this page.
e) 8z - 8 = 6z + 8
Rearranging, we have;
8z - 6z = 8 - 6
2z = 2
z = 2/2
z = 1
f) 3(r+10) + 200 = 236
Expanding the bracket and rearranging, we have;
3r + 30 = 236 - 200
3r = 236 - 200 - 30
3r = 6
r = 6/3
r = 2
So we now have;
x = 6; y = 4; z = 1; p = 2; q = 8; r = 2
Mobile number is; 9 6 4 1 2 7 8 1 2 3

<span><span><span>3x</span>+<span>4y</span></span>=8
</span>Add -4y to both sides
<span><span><span><span>3x</span>+<span>4y</span></span>+<span>−<span>4y</span></span></span>=<span>8+<span>−<span>4y</span></span></span></span><span><span>3x</span>=<span><span>−<span>4y</span></span>+8

Answer:
1800 words = 1 hour
1800 words = 60 minutes
Divide by 60: 30 words per minute.

The answer is: "
41 / 11 " ; or, write as: "
41 : 11 " .
__________________________________________________________Explanation:__________________________________________________________72/99 = (72÷9) / (99÷9) = 8/ 11 .
So, 3.727272727272... = "3
" .
→ "3
" = [(11 *3) + 8] / 11 = (33 + 8) / 11 = 41 / 11 .
__________________________________________________________ "41 / 11" cannot be simplified any further; so the answer is:
__________________________________________________________ "
41 / 11 " ; or, write as: "
41 : 11 " .
