Answer:
s = -7.8
Step-by-step explanation:
from the question 12=10(s+4)+50
<u>first step</u>
open the bracket and evaluate for the value of s
12=10(s+4)+50
12 = 10s + 40 + 50
12 = 10s + 90
collect or combine the like terms
12-90 = 10s
-78 = 10s
divide both side by 10
-78/10 = 10s/10
-7.8 = s
therefor s = -7.8
Answer: x=5
5x-3 (x-3)= -6 +6x -5
5x -3x +9 =-6 +6 x -5
Answer:
Step-by-step explanation:
|3x+12|
one is as it is one is the negative value of it
3x + 12 - (3x + 12)
- 3x - 12
That is because both negative and positive values put in am absolute value become positive.
Answer:
10.24 in²
Step-by-step explanation:
First we need to know how to find the area of a rectangle, which is base * height.
We can notice that the base and height are both 3.2, so we multiply 3.2*3.2.
To do this, we first have to completely ignore the decimal points. Just pretend you're multiplying 32*32, to get 1024. Then, we count how many numbers are past the decimal point on each number. On both, there is 1 number past, and we add those together to get 2 numbers past the decimal point.
We then, finally, make the number we got (1024) have 2 numbers past the decimal point, so instead of 1024, we have 10.24, which is our answer!
