Answer:
1. x > 9
2. n < 5
3. b > 2
4. p < 4
5. p < -2
6. m > 0
Step-by-step explanation:
1.
x - 2 - 2 > 5
x - 4 > 5
x > 5 + 4
x > 9
2.
5 + n < 2 x 5
n < 10 - 5
n < 5
3.
50b > 100
b > 100 : 50
b > 2
4.
-5 + p + 2 < 1
p < 1 + 3
p < 4
5.
p + 6 + 8 < 12
p + 14 < 12
p < 12 - 14
p < -2
6.
80m - 64 - 2 > -66
80m > -66 + 66
m > 0:80
m > 0
Answer:
Bigger number = 42
Smaller number = 10
Step-by-step explanation:
Step 1: Define variables
<em>x</em> = larger number
<em>y</em> = smaller number
Step 2: Write systems of equations
x + 2y = 62
3x = y + 116
Step 3: Rewrite 1st equation
x = 62 - 2y
Step 4: Substitution
3(62 - 2y) = y + 116
186 - 6y = y + 116
186 = 7y + 116
70 = 7y
y = 10
Step 5: Plug in <em>y</em> to find <em>x</em>
x + 2(10) = 62
x + 20 = 62
x = 42
3x+2=x+2x+4
-2 -2
3x=x+2x+4-2
3x=3x+4-2
-3x -3x
x= 4-2
x=2
Step-by-step explanation:
a, 1/4+2/5=13/20
b,-1/8+1=7/8
c, 4/25×-1/8=-1/50
d, 2×1/9-1/2=2/9-1/2=-5/18
e, 1+2/5-1/4=7/5-1/4=23/20
