Step-by-step explanation:
Let her brother's age be x
Sarah age = 2x + 4
Answer:
387
Step-by-step explanation:
To evaluate 3 - 6( Z - 2) ^3 at Z = -2, replace Z with -2:
3 - 6( -2 - 2) ^3
Simplify this result, obtaining 3 - 6( -4) ^3.
According to order of operations rules, exponentiation must be done first here, before multiplication and before subtraction. Therefore:
3 - 6( -4) ^3 → 3 - 6( -64). Again, these rules require that we multiply before subtracting:
3 - 6( -64) = 3 + 384, or 387

Answer:
8 assistant caregivers
7 senior caregivers
Step-by-step explanation:
6 assistant caregivers (current) + 2 assistant caregivers (new)
= 8 total assistant caregivers
(6 + 2 = 8)
4 senior caregivers (current) + 3 senior caregivers (new)
= 7 total senior caregivers
(4 + 3 = 7)
Answer:
One solution: (2.5,0)
Step-by-step explanation:
We can use substitution for the solution. Substitute y=2x-5 to -8x-4y=-20 so that you end up with -8x-8x+20=-20. Next you want to add like terms which will be -16x+20=-20, next you want isolate x by subtracting 20 from both sides and leaves you with -16x=-40. Divide -16 on both sides to fully isolate x and will leave you with x=2.5. Now substiture in 2.5 for x in y=2x-5 to get y=2(2.5)-5 which will then lead to y=0.
