Answer:

2/3 * 1/3 = 2/9

Step-by-step explanation:

You see the top 2 lines being shaded which is 2/3's of the whole square.

The second shaded part only covers 1/3 of the whole square.

Thus, you multiply both parts to figure out the darkest shaded part!

-5+2a=4a-4-3a help plz and thank you

sattari [20]

Answer:

a=1

Step-by-step explanation:

To make this easier, combine like terms first.

-5+2a=4a-4-3a

-5+2a=a-4

Then, add 5 on both sides.

-5+2a=a-4

+5 +5

2a=a+1

Now, subtract a on both sides.

2a=a+1

-a -a

a=1

Hope this helps you out!!!! Have an amazing day :3

Brett shaded 4/8 of a sheet of notebook paper. Aisha says he shaded 1/2 of the paper. Are the two fractions equivalent? if so, w

vladimir2022 [97]

Answer:

The two fractions are equivalent; another equivalent fraction is 3/6

Step-by-step explanation:

$\frac{1}{2}$ x 4 = 4/8, therefore the fractions are equivalent.

1/2 x 3 = 3/6 which is equivalent to 1/2.

Treble 29 = 160- ? By the way, treble is triple. Please answer correctly! This is for Maths.

x = ?

160 - 29 = 131

SO x = 131

160 - 131 = 29

SO,

29 = 160 - 131.

Let $S = 2010 + 2011 + \cdots + 4018$. Compute the residue of $S$, modulo 2009.

Yakvenalex [24]

Notice that

2010 ≡ 1 mod 2009

2011 ≡ 2 mod 2009

2012 ≡ 3 mod 2009

...

4017 ≡ 2008 mod 2009

4018 ≡ 0 mod 2009

So really, S is just the sum of the first 2008 positive integers:

$S=\displaystyle\sum_{n=1}^{2008}n=\frac{2008\cdot2009}2$

where we invoke the formula

$\displaystyle\sum_{i=1}^ni=\frac{n(n+1)}2$

and so S ≡ 0 mod 2009.
