If 5-3(2a+1)=-4+10, what is the value of a+2

givi [52]

$\\ \rm\Rrightarrow 5-3(2a+1)=-4+10$

$\\ \rm\Rrightarrow 5-6a-3=6$

$\\ \rm\Rrightarrow -6a+2=6$

$\\ \rm\Rrightarrow -6a=6-2$

$\\ \rm\Rrightarrow -6a=4$

$\\ \rm\Rrightarrow a=\dfrac{4}{-6}$

$\\ \rm\Rrightarrow a=\dfrac{2}{-3}$

Now

$\\ \rm\Rrightarrow a+2$

$\\ \rm\Rrightarrow \dfrac{2}{-3}+2$

$\\ \rm\Rrightarrow \dfrac{2-6}{-3}$

$\\ \rm\Rrightarrow \dfrac{-4}{-3}$

$\\ \rm\Rrightarrow \dfrac{4}{3}$

Can anybody please help me

faltersainse [42]

Answer:

324

Step-by-step explanation:

The shirt would be the same value because they are the same so

288÷3=96

Pi Shirt = 96

then work out the 3rd one to find out the balloons

98+ balloon + balloon= 226-96=130÷2= 65

Balloons = 65

then work out the 2nd one 195÷65=3

Pizza = 3

Then 4th one

25+1=26-3=29

Maccoroni = 29

Last question

96×3+65-29=324

The answer would be positive 24. The reason being is because of the fact that two negatives when multiplied cancel the negative. Also 12 * 2 is 24 so yeah
