Answer:
51
Step-by-step explanation:
2*5=10
3*10=30
11*1=11
10+30+11
51
5(x+2) turns into 5x+10 where 5x+2 is already in its simplified form so to write it as 5x+2 instead would make you get the wrong answer.
<span>2x+3y=3
</span><span>-3x-2y=8
3y=3-2x
-2y = 8+3x
y = 1 - 2x/3
y = -4 - 3x/2
</span>1 - 2x/3 = -4 - 3x/2
5 = - 3x/2 + 2x/3
5 = -9x/6 + 4x/6
5 = -5x/6
x = 5 * 6/-5
x = -6
No plug it in.
<span>2x+3y=3 ; x = -6
-12 + 3y = 3
3y=3+12
3y=15
y = 5
So </span>x = -6 and y = 5
Answer: -2.10
Step-by-step explanation:
Given : 

Sample size : n= 50, since the sample size is greater than 30 , so we apply z-test.
Sample mean : 
Standard deviation : 
The test statistic for population mean :-

i.e. 
Hence, the value of the test statistic = -2.10

So, let's start off with h
The expression needs to be '3 more than h'
This can be written as:
h + 3
The expression also needs to be 'five times' this value
This can be written as:
5(h + 3)
That would be your answer ^^
Have A Nice Day ❤
