Answer:
x≤16
Step-by-step explanation:
1/2x - 3 ≤5
Add 3 to each side
1/2x -3+3 ≤5+3
1/2x≤8
Multiply each side by 2
1/2x*2 ≤8*2
x≤16
X=21<span>°
</span>y=31.5<span>°
Explanation:
Since it is a whole circle (360</span>°) and there are 40 section (90<span>° each).
2 of the 90</span>° +(180°)<span>are clearly stated there so you do:
360</span>°-180°=180<span>°
</span>
1. On the side that have 2 'y's you do:
90°-(12+15)=63
Then 63/2=31.5<span>°
</span>Therefore y=31.5<span>°
</span>
2. On the side with 3 'x's you do:
90<span>°-(12+15)=63
Then 63/3=21</span><span>°
</span>Therefore x=21<span>°
To cross check you do:
90+90+15+12+21+21+21+15+12+31.5+31.5=360

The required salary of Juma in July month is sh.9600.
Given that,
he spent half of his July salary on school fees and two-thirds of the remainder on food.
he spent sh.3200 on food.
<h3>What is arithmetic?</h3>
In mathematics, it deals with numbers of operations according to the statements.
In the question,
Let the slay of Juma in July be x,
Juma spent half of his July salary on school fees = x/2
two-thirds of the remainder on food = 2/3 * x/2 = x/3
he spent sh.3200 on food i.e.
x / 3 = 3200
x = 3200 * 3
x = 9600
Thus, the required salary of Juma in July month is sh.9600.
