Now ,
No 1). x + 13 =28
X = 28-13
Therefore x = 15 ans
No 2). X - 10 = 24
X = 24 + 10
Therefore x = 34 ans
No 3). 2x = 40
X =40/2
Therefore x = 20 ans
No 4). X+8 > -12
X > -12-8
Therefore X > -20 ans
Inequality={-19,-18,-17.........}
No 5). Plz right it clearly i don’t understand the sign is Multiply or X
Hope this helps !
Please mark it as the brainliest <3

Answer: z= -2.35
Step-by-step explanation:
When the population variation is know, then we calculate the z-statistic.
Formula to calculate the z-test statistic is given by :-
where , n= sample size
= sample mean
= Population mean
=Population standard deviation.
As per given we have,
n= 270
Then, z-statistic will be
(Substitute all the values )
Hence, the value of the test statistic= z= -2.35

Answer:
$0.94 is the price of one donut at Sunrise Donuts
Step-by-step explanation:
Let x be the price of one donuts and y be the price of one kolaches.
As per the statement:
At Sunrise Donuts you can buy 6 donuts and 2 kolaches for $8.84.
⇒ .....[1]
It is also given that One kolache and 4 donuts would cost $5.36.
⇒ .....[2]
Multiply equation [2] by 2 to both sides we have;
......[3]
Subtract equation [1] from [3] we have;
Divide both sides by 2 we have;
x = $0.94
Therefore, $0.94 is the price of one donut at Sunrise Donuts.
