D. please mark me brainliest
Step-by-step explanation:
So thie equation basically means 2 times a number and 4 times 2 and the sum of that so as a equation it is 2*n+8 so it is n+4 times 2 so twice the sum of a number and 4
Slope= 3/2
CORRECT IF WRONG!!
Let x represent the number of hours he worked during the weekdays (not Saturday or Sunday).
If x is how much he worked on the weekdays and he worked 5 times as much on Sat and Sun, then hopefully you agree that on Sat and Sun he worked 5x hours.
So we have 5x hours on the weekends and x hours on the weekdays, so in total for the whole week we have 5x + x = 6x hours in total.
The question tells us that he worked 30 hours total, so 6x = 30
Divide both sides by 6 to isolate x and we have x = 5.
He worked 5 hours the rest of the week.
Hope this helps. If it does, please be sure to make this the brainliest answer! :)
Standard form is just putting (in this case) variables in alphabetical order. First we simplify- 2x+4=4y would become 1/2x+1=y. This is already in standard form, as numbers w/o variables come at the end. simplifying the next one is more tricky. first you get a variable/number alone-
9-2x-2y=4x+3
9-2y=6x+3
6-2y=6x
1-1/3y=x
1=x+1/3y
3=x+y
x+y=3
sorry if I was wrong and not of any help, But I do believe this is correct.
We know that
area of lateral faces of the <span>right triangular prism=perimeter of base*height
perimeter of the base=[3+4+5]----> 12 cm
height of the prism=5 cm
so
</span>area of lateral faces of the right triangular prism=12 cm*5 cm---> 60 cm²
the answer is
60 cm²
