Answer:
idk i kinda forgot what was the answer let me go check
4(4m -3) + -1m(m + -5) = -52
4(-3 + 4m) + -1(m + -5) = -52
(-3 * 4 + 4m * 4) + -1(m + -5) = -52
(-12 + 16m) + -1(m + -5) = -52
-12 + 16m + -1(-5 + m) = -52
-12 + 16m + (-5 * -1 + m * -1) = -52
-12 + 16m + (5 + -1m) = -52
-12 + 5 + 16m + -1m = -52
-12 + 5 = -7
-7 + 16m + -1m = -52
16m + -1m = 15m
-7 + 15m = -52
-7 + 15m = -52
-7 + 7 + 15m = -52 + 7
-7 + 7 = 0
0 + 15m = -52 + 7
15m = -52 + 7
-52 + 7 = -45
15m = -45
15m ÷ 15 = -45 ÷ 15
m = -3
m = -3

Answer:
3
Step-by-step explanation:
Since the shelves are 75.5cm long, the total length she would be needing is 75.5cm × 6 = 453cm
Now, the length of the wood she is using is 180cm, to get enough length to make the shelves, we would need to divide 453cm by 180cm which gives a value of around 2.51
This is approximately equal to 3 when rounded up to the nearest whole number.

this too hard idk like C idk bc C is betwwed B and D
Answer:adult=75
Students = 200
Children=75
Step-by-step explanation:
Let x= adult tickets, y=students, z=child
x+y+z =350
Since x=z
y+2z= 350 -----------1
20x +12y + 10z = 4650
Since y=z
12y +30z = 4650 --------2
Using elimination method to solve eqn 1&2
Multiply eqn 1 by 12
12y + 24z = 4200
12y +30z = 4650
Subtract equ 2 from 1
-6z =-450
z=75, x = 75
y=350 -(75+75)
y= 200 tickets
