Step-by-step explanation:
x decreased by 60% = (1-0.60)x = 0.40x
x increased by 80% = (1+0.80)x = 1.80x
Answer:
This value of x will make equation true
Step-by-step explanation:
Given as ;
3x - = 7x -
I,.e - = 7x - 3x
Or, = 4 x
∴ x=
Hence this value of x will make equation true Answer

Step-by-step explanation:
to find surface area you multiply things like a*b a*c b*c, but you only need two in this case,you dont need 4.3*14, so it just 4.3*5 and 5*14, multiply those and add em
Answer:
j = $15
t = $5
Step-by-step explanation:
This question can be solved using simultaneous equation
let the price of t-shirt be represented with t
let the price of jeans be represented with j
From the question, these two equations can be derived
2j + 6t = 60 eqn 1
4j + 3t = 75 eqn 2
multiply eqn 1 by 2
4j + 12t = 120 eqn 3
Subtract eqn 2 from 3
9t = 45
divide both sides by 5
t = 5
Substitute for t in eqn 1
2j + 6(5) = 60
2j = 30
j = 15
