c and b hope it helps you in the long run
Perimeter=4h+4
If the base is 2 more than the height, it gives us the equation:
b=h+2
The equation for the perimeter of a rectangle can be though of as 2b+2h, so substituting in (h+2) for b from the first equation, we get 2(h+2)+2h.
This can be simplified to be 2h+4+2h or 4h+4
Answer:
18cm
Step-by-step explanation:
20/10 = 2cm
So since 2x10 is 20 and it exceeded only 10%, we only subtract 2 from 20 which you leave you with 18cm.
Answer:
690
Step-by-step explanation:
Let
hayden have "h"
uri have "u"
and
willow have "w"
Hayden & Uri have 1250. we can write:
h + u = 1250
Hayden & Willow have 830, so we can write:
h + w = 830
Uri has 4 times than Willow, so we can write:
u = 4w
Putting 3rd equation in first, we get:
h + u = 1250
h + 4w = 1250
Now, we take 2nd and 4th equation, which are:
h + w = 830
h + 4w = 1250
Multiplying this first one with -1, gives us:
-1 * [h+w=830] = -h - w = -830
Now we add this up with 4th equation. Shown below:
- h - w = - 830
h + 4w = 1250
----------------------
4w - w = 1250 - 830
3w = 420
w = 420/3
w = 140
We know u = 4w, so u = 4 * 140 = 560
u = 560
Also, we know h + w = 830, so
h + 140 = 830
h = 830 - 140
h = 690
Thus Hayden has 690
