(2/5)(x-1)<(3/5)(x+1) perform indicated multiplications
(2x-2)/5<(3x+3)/5 multiply both sides by 5
2x-2<3x+3 add 2 to both sides
2x<3x+5 subtract 3x from both sides
-x<5 divide both sides by -1 (remember to reverse direction of inequality sign when multiplying/dividing by a negative value)
x>-5
3 INCHES= 42 MILES. 42 <span>MILES</span> DIVIDED BY 322 MILES= 7.6
3X7.6= 22.8 INCHES APART
To figure out how much every person would pay for electricity, divide the cosy by 4.
Answer:
1/7
Step-by-step explanation:
just multiply 1/4 with 1/3
1/4 × 1/3 = 1/7
Answer:
y = - 4.4
Step-by-step explanation:
Given that t varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 6.6 when x = 9.9 , that is
- 6.6 = 9.9k ( divide both sides by 9.9 )
k = 
= - 
y = - k ← equation of variation
When x = 6.6, then
y = - × 6.6 = - 2 × 2.2 = - 4.4
