A textbook store sold a combined total of 438 biology and psychology textbooks in a week. The number of psychology textbooks sol
Liono4ka [1.6K]
<h2>Answer:</h2>

Number of biology textbooks sold: 257 textbooks

Number of psychology textbooks sold:​ 181 textbooks

<h2>Explanations:</h2>

Let the total number of biology textbook sold be "a"

Let the total number of psychology textbook sold be "b"

If a textbook store sold a combined total of 438 biology and psychology textbooks in a week, then:

a + b = 438 ................... 1

If the number of psychology textbooks sold was 76 less than the number of biology textbooks sold, then;

b = a - 76 ...................... 2

Substitute equation 2 into 1

a + (a-76) = 438

a + a - 76 = 438

2a = 438 + 76

2a = 514

a = 514/2

a = 257 biology textbooks

From equation 2;

b = a - 76

b = 257 - 76

b = 181 psychology textbooks

Number of biology textbooks sold: 257 textbooks

Number of psychology textbooks sold:​ 181 textbooks

Kevin claims he can draw a trapezoid with three right angles. Is this possible? Explain.
statuscvo [17]
No it is NOT possible - that would mean the final angle would also have to be ninety degrees making it a square or rectangle. :)
