Answer:
B
Step-by-step explanation:
5x-9 = 3x+3
2x-9 = 3
2x = 12
x= 6
plz mark branliest, hopoe this helps :)
(a)
4x + 3y = 23
5x + 2y = 20
(b)
4x + 3y = 23 ⇒ -2(4x + 3y = 23) ⇒ -8x - 6y = -46
5x + 2y = 20 ⇒ 3(5x + 2y = 20) ⇒ 15x + 6y = 60
7x = 14
x = 2
5x + 2y = 20
5(2) + 2y = 20
10 + 2y = 20
2y = 10
y = 5
Answer: biscuit = $2, ice cream = $5
b. The sidelines are parallel by the Same-Side Interior Angles Theorem.
c. The sidelines are perpendicular by the Perpendicular Transversal Theorem
d. The sidelines are parallel because they are perpendicular to the same line.
The true statement about the sidelines would be that they are parallel because they are both perpendicular to each of the boldly marked line.
Therefore, since the sidelines are perpendicular to the same set of lines, then the sidelines would be parallel.

The final expression will be 12m + 22 .
Given,
6m+3(2m+5)+7
Here,
6m+3(2m+5)+7
To solve the above expression firstly open the brackets by multiplying 3 inside the bracket .
So,
6m + 6m + 15 + 7
Now add the the terms having similar variables ,
So,
6m and 3m will be added,
= 12m
Now add the constant terms,
15 + 7 = 22
Thus the final expression will be ,
12m + 22

Answer:
y=13
Step-by-step explanation:
if x=20 when y=8 (we can creat equation )
x=2y+4 (you can prove that the equation is correct by substitute )
so the question is if x=30 find the value of y
30=2y+4
30‒4=2y
26=2y
26/2=2y/2
13=y
i hope this helps you
