Answer:
Q. 2)Perimeter =2(l+b)
So,
2(8x-8 +8x)=80cm(Given in Question)
= 2*16x-8=80cm
16x- 8= 80 divided by 2,
16x=40+8=48
x=48 divided by 16
X=3
Q.1) Perimeter=2(l+b)
2(2x+8 +4x)=76cm(Given in Question)
2* 6x +8=76
6x+8= 76 divided by 2, 38
6x= 38-8, 30
x= 30 divided by 6 = 5
X=5

1. 2x+8=3x+10
Step 1: Subtract 3x from both sides.
2x+8(-3x)= 3x+10 <span>(-3x)
</span>-x+8=10
Step 2: Subtract 8 from both sides.
-x+8 (-8) = 10 <span>(-8)
</span>-x=2
Step 3: Divide both sides by -1.
-x/(-1)=2/(-1)
x=-2
Answer= x=-2
2. -3x+9=2x-1
Step 1: Subtract 2x from each side.
-3x (-2x) +9= 2x-1 <span>(-2x)
</span>-5x+9=-1
Step 2: Subtract 9 from both sides.
-5x+9 (-9)=-1 (-9)
-5x=-10
Step 3: Divide -5 from both sides.
-5x/-5= -10/-5
x=2
The answer is 2.
3. 4x-7=5x-6
Step 1: Subtract 5x from both sides.
4x-7 (-5x)= 5x-6 (-5x)
-x-7=-6
Step 2: Add 7 to both sides.
-x-7 (+7)= -6 (+7)
-x=1
Step 3: Divide each side by -1.
-x/-1=1/-1
x=-1
The answer is -1.
Can I have brainliest since u did t put a picture :)
X=number of games played
just do simple multiplication
remember that orded pairs are (x,y)
x=5
y=0.50(5)+3
y=2.5+3
y=5.5
orderd pair is (5,5.5)
x=10
y=0.50(10)+3
y=5+3
y=8
ordered pair is (10,8)
x=20
y=0.50(20)+3
y=10+3
y=13
ordered pair is (20,13)
(5,5.5)
(10,8)
(20,13)
