Answer:

$- 23$

Step-by-step explanation:

$24 \div {2}^{2} ( - 3) - 7 - {2}^{2} - 2(3 - 6) \\ 24 \div {2}^{2} ( - 3) - 7 - {2}^{2} - 2( - 3) \\ 24 \div 4( - 3) - 7 - 4 - 2( - 3)\\ 6(-3) - 7 - 4 -2(- 3) \\ - 18 - 7 - 4 + 6 \\ -25 -4 +6 \\ -29 +6 \\ - 23$

Nathaniel builds birds and birdhouses using Lego blocks. Let BBB represent the number of birds and HHH represent the number of b

vladimir1956 [14]

Answer:

(C) Nathaniel can build at most 3 birdhouses.

Step-by-step explanation:

Given that:

$43B+215H \leq 3000$

where:

B represents the number of birds
H represents the number of Birdhouses

Nathaniel wants to build 50 birds(B) using lego Blocks, we want to determine how many birdhouses(H) he can build with the remaining Lego blocks.

If B=50

$43(50)+215H \leq 3000\\2150+215H \leq 3000\\\text{Subtract 2150 from both sides}\\215H \leq 3000-2150\\215H \leq 850\\\text{Divide both sides by 215}\\H \leq 3.95$
