Answer:

Step-by-step explanation:

∠IHE and ∠GHF are vertical angles.

Vertical angles have the same measures (are congruent).

Therefore, if m∠IHE = d + 44 and m∠GHF = 4d - 25, then we have the equation:

d + 44 = 4d - 25 subtract 44 from both sides

d + 44 - 44 = 4d - 25 - 44

d = 4d - 69 subtract 4d from both sides

d - 4d = 4d - 4d - 69

-3d = -69 divide both sides by (-3)

-3d/(-3) = -69/(-3)

d = 23

Equation, find y when x=-3. y = -x + 5 When x = -3, y =

Step2247 [10]

I think y = 8. Since x = -3 then the equation would be y = -1(-3) +5. -1 times -3 equals 3. So now the equation is y = 3 +5. That would give you 8.

Step-by-step explanation:

Use the correct order of operations and do one step at a time to avoid making mistakes.

$16 \div 4 + 2^3 \times 5 - 3 =$

$= 4 + 8 \times 5 - 3$

$= 4 + 40 - 3$

$= 44 - 3$

$= 41$
