Answer:
Step-by-step explanation:
We first need to define a couple of variables. Let s = the cost of 1 squash and z = the cost of 1 zucchini.
Now lets translate the words into algebra:
"The cost of 5 squash and 2 zucchini is $1.32" ===> 5s + 2z = 1.32
"Three squash and 1 zucchini cost $0.75" ===> 3s + z = 0.75
There are several ways to solve systems of equations. Let's use substitution. We can find what z equals in terms of s by manipulating the second equation:
3s + z = 0.75
-3s -3s
------------ -------------
z = -3s +0.75
Now lets substitute (-3s + 0.75) into the first equation for z, then solve for s:
5s + 2(-3s + 0.75) = 1.32
Can you handle it from here?
(Hint: Once you have solved for s, you can substitute that value back into either of the equations and solve for z.)
The labor-force participation rate of Belgium in 2017 was 77.78%
1.
Given:
Adult population = 4500
Number of employed in 2017 = <em>2800</em>
Number of Unemployed in 2017 = 700
Labor force participation rate = (employed + unemployed) / total population × 100
= (2800 + 700) / 4,500 × 100
= 3,500 / 4500 × 100
= 0.777777777777777 × 100
= 77.77777777777777%
Approximately, 77.78%
2.
Given:
Adult Population in 2016 = 3500
Number of employed in 2016 = 1800
Number of Unemployed in 2016= 600
Unemployment rate = unemployed population/ total labor force × 100
= 600 / 3,500 × 100
= 0.171428571428571 × 100
= 17.14285714285714%
Approximately,
17.14 %
Therefore, the unemployment rate of Japan in 2016 was 17.14%

Answer:
u=2
Step-by-step explanation:
8u-21 = 2u-9
+21 +21
8u= 2u + 12
-2u -2u
6u= 12
divide by 6, u=2 !!
