Well 88 is 88% and 98% but if you round 88 would turn into 90% and 98 would become 100%. and 100% minus 90% is 10% so the broadcaster had about a 10% error.
I am sure not 100% right because i don't quite know percents yet.
So good luck.
Mark me the Brainiest please.

Simplify 6m2n3 – 3m3n2 + 8m2n3 + 12m3n2
NISA [10]
Hello! Hope I can assist you.

Let us simplify some terms first!

6m\cdot \:2n\cdot \:3 \ \textgreater \  36mn
3m\cdot \:3n\cdot \:2 \ \textgreater \  2\cdot \:3^2mn
8m\cdot \:2n\cdot \:3 \ \textgreater \  48mn
12m\cdot \:3n\cdot \:2 \ \textgreater \  72mn

36mn-2\cdot \:3^2mn+48mn+72mn

From here, group like terms
36mn-2\cdot \:3^2mn+48mn+72mn

\mathrm{Add\:similar\:elements:}\:36mn+48mn+72mn=156mn
156mn-2\cdot \:3^2mn

2\cdot \:3^2mn \ \textgreater \  2\cdot \:9mn \ \textgreater \  18mn

156mn-18mn

\mathrm{Add\:similar\:elements:}\:156mn-18mn=138mn

Hope this helps!

In parallelogram DEFG, DH = x + 3, HF = 3y, GH = 4x – 5, and HE = 2y + 3. Find the values of x and y.
marissa [1.9K]

Here, DH = HF 

x+3 = 3y

x = 3y-3   ----(I)

GH = HE

4x-5 = 2y+3

4x = 2y+8

Substitute value of x,

4(3y-3) = 2y+8

12y-12 = 2y+8

12y-2y = 12+8

10y = 20

y = 2

Now, substitute it in equation 1,

x = 3(2)-3

x = 6-3 = 3

So, your final answer is      x=3  & y=2

Step-by-step explanation:

3/4 is 3 times 1/4, so the number of walls Dan can paint is 3 times the number of cans Dan uses.

A. 1/2 can will paint 3/2 walls, not 2.

B. 1 can will paint 3 walls — true

C. 5/3 cans will paint 5 walls — true

D. 2 cans will paint 6 walls, not 8.

E. 5/2 cans will paint 15/2 = 7 1/2 walls, not 10.

F. 11/3 cans will paint 11 walls — true
