Answer:
35
Step-by-step explanation:
-5{3-2[1-4(3-2^2)]}
we work inside out
using PEMDAS
parenthesis, exponents, multiply and divide, add and subtract
the very most inside
(3-2^2)
do the exponents
3 - 4 = -1
replace where it was in the original equation
-5{3-2[1-4(-1)]}
take the next set of parenthesis (bracket are the same as parenthesis)
[1-4(-1)]
multiply
4*-1 = -4
1--4 = 1+4 = 5
replace where it was in the original equation
-5{3-2[5]}
next set of parenthesis
{3-2[5]}
3 - 10 = -7
replace where it was in the original equation
-5 {-7}
35
It makes a rectangle if graphed.

Answer:
They'll meet after 200 meters , if they simultaneously start running towards each other.
Step-by-step explanation:
Let x =distance travelled by dog and 200-x be the distance travelled by cat. Inorder to meet, the sum of their travelled distances shall be equal to 200 meters as they are far apart by 200 meters.
Dog: Distance =Speed x time: x=30t
Cat: Distance = 200-x
=24t
The sum of their distance travelled shall be 200 meters: 30t+ 24t= 200;54t=200;t=200/54=3.7secs
So they will meet after 3.7 seconds
To check:
Distance travelled by dog :x=30(3.7)
=111.11 meters
Distance travelled by cat: 24t=24(3.7)
=88.89 meters
Therefore since they are travelling towards each other and their distance apart is 200 meters, after 3.7 seconds they will meet because dog travelled 111.11 meters and cat travelled 88.89 meters and they covered already 200 meters as the sum of 111.11+ 88.89
=200 meters
Answer:
just do the opposite numbers on the left side and do the 2nd function on the right!
Step-by-step explanation:
Im not sure if its y=19
y= 6(5)-11
y=30-11
y=19
