Answer:
-2+11x
Step-by-step explanation:
Combine like terms
(-5+3)+(x+10x)
-5+3 = -2
x+10x = 11x
-2+11x
Answer:
14/19
Step-by-step explanation:
Note that there are two " - " signs here. Thus, the end result will be " + "
We move from left to right, obtaining first 10/19 divided by (5/7):
10
----- ÷ (5/7)
19
To divide by (5/7), invert (5/7) and then multiply. We get:
10 7 2(7)
----- * ----- = ------- = 14/19
19 5 19
Answer:
<em><u>greater</u></em>
Step-by-step explanation:
3/6= <em><u>0.5</u></em>
1/3= <em><u>0.333</u></em>...
0.5>0.333...
7x+2
Step-by-step explanation:
add all the sides of the pentagon and make it equal to the perimeter of the square which is 4y
sides of the pentagon are
5x+3
2x+3
7x+4
9x-10
5x+8
28x+8=4y
7x+2 = y
7x+2 = answer

another way :
in a standardized test you may want to use real numbers
make x equal a prime number like 3
so then the sides are
18
9
25
17
23
=
92
then divide by 4
23
then divide by 3
which is 7 remainder of 2
which is
7x+2
Let's be a and b the sides of the rectangle.
1 Area is 1600 =a*b
2. Perimeter is 2(a+b)=160 ==>b=80-a
So,
1600=a*b=a*(80-a)==>80a-a²=1600
==> a²-80a+1600=0
==> (a-40)²=0
==>a=40 or a=-40 (to exclude since <0)
==>b=1600/40=40
The rectangle is a square of 40m of side.
