Answer:
The equations that are true are
B
C
E
Step-by-step explanation:
A) States that 0 + 451 = 0, but that is not true because...
0 + 451 = 451
B) States that 130 + 210 = 210 + 130, and that is true because...
130 + 210 = 210 + 130
340 = 340
C) States that (127 + 80) + 250 = 127 + (80 + 250), and it is true because...
(127 + 80) + 250 = 127 + (80 + 250)
127 + 80 + 250 = 127 + 80 + 250
457 = 457
D) States that (123 + 57) + 180 = 153 + (87 + 180), but that is not true because...
(123 + 57) + 180 = 153 + (87 + 180)
123 + 57 + 180 = 153 + 87 + 180
360 = 420 (but this does not make sence)
E) States that 497 + 0 = 497, and it is true because...
497 + 0 = 497
497 = 497
Answer:
The ordered pair make both inequalities true
Step-by-step explanation:
we have
------> inequality A
------> inequality B
we know that
If a ordered pair satisfy both inequalities
then
the ordered pair is a solution of both inequalities
we're going to verify every case
<u>case A)</u> point
Substitute the values of x and y in both inequalities
<u>Inequality A</u>
------> is not true
therefore
The ordered pair does not make both inequalities true
It's not necessary to verify the B inequality
<u>case B)</u> point
Substitute the values of x and y in both inequalities
<u>Inequality A</u>
------> is true
<u>Inequality B</u>
------> is true
therefore
The ordered pair make both inequalities true
<u>case C)</u> point
Substitute the values of x and y in both inequalities
<u>Inequality A</u>
------> is not true
therefore
The ordered pair does not make both inequalities true
It's not necessary to verify the B inequality
<u>case D)</u> point
Substitute the values of x and y in both inequalities
<u>Inequality A</u>
------> is not true
therefore
The ordered pair does not make both inequalities true
It's not necessary to verify the B inequality
Answer:
36 centimeters
Step-by-step explanation:
always start with the bigger number first then divide 72 ÷ 2 = 36 then divide 72 ÷ 36 = 2 then the actual building will be 36
