Answer:
31.5
Step-by-step explanation:
You have to break the shape up into a triangle and a rectangle
Area of a Triangle:
A=1/2(b)(h)
=1/2(7)(3)
=1/2(21)
=10.5
Area of Rectangle:
A= (b)(h)
=(7)(3)
=21
Area of Total Shape:
10.5 + 21
=31.5
Answer:
10 days
Step-by-step explanation:
Jenny has read 50 pages and will read 15 each day.
The equation would be: 15x+50
Mark will read 20 pages daily.
The equation would be: 20x
In both equations x represents days.
You set both equal to each other because you want to know when they read the same amount of pages.
15x+50=20x
...you subtract 15x from both sides
50=5x
...and divide by five to get: 10 days
Answer: -2
Step-by-step explanation:
since there are no multiplication you can simply go from left to right doing simple math. You start from a +4 that would be a positive 4, you subtract -3 so you get +1 then you subtract -4 and the result is -3 (negative 3) so now you are currently working with numbers lower than 0, adding +2 will make it -1 and finally you subtract for -1 and that will make it -2.
