Answer:
x = 12.75
∠C = 51.75°
Step-by-step explanation:
The two marked angles are complementary, so ...
(5x -12) +(3x) = 90
8x = 102
x = 102/8
x = 12.75
__
C = (5x -12)° = (5(12.75) -12)°
∠C = 51.75°
__
<em>Check</em>
E = 3x = 38.25, then C+E = 51.75 +38.25 = 90 . . . . as it should
Well since we can use a base of 1 we know that 1 - 45 is less than 4 but -1 + 45 is not, which follows the assumption that x>0, but now we need to know what x is less than to fit the inequality. If we use 5 as a trial we can see that 5 - 9 = -4 so 0<x<5 is your answer. Hope this helps I basically used trial and error. If you want to check try 3 or 4 for x and it will work but 6 will not.
2x373 because 2 and 373 are both prime meaning they can only be divided by one and themselves
Answer:
10
Step-by-step explanation:
Answer:
x = 200 packages.
B
Step-by-step explanation:
1 strip of tape = 2.375 inches
Each package requires 4 such strips or 4 * 2.375 which is 9.5 inches.
Set up a proportion for the rest of the problem
1 package / 9.5 inches tape = x packages / 1900 inches tape.
Multiply both sides by 1900
1*1900 / 9.5 = x
1900/9.5 = x
x = 200 packages.
