Answer:
[See Below]
Step-by-step explanation:
✦ Turn fractions into decimals:
- (We will do something different for
and 
.)
✦ Divide:
- ÷
- (Since the denominators are multiplies of each other we can divide them without having to change them into decimals.)
✦ Simplified Equation:
✦ Add:
✦ Subtract:
- (Subtraction rule is if there is 2 negatives next to each other in a problem it turns into a positive.)
✦ So your answer would be:
(Exact Form)
(Mixed Number Form)
(Decimal Form)

<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
Answer: Chef Andre used more than 3 and one-half cups of flour.
Step-by-step explanation:
This is the > ‘greater than sign. For the question, we are to get the inequality that shows that"c is greater-than 3 and one-half".
Let Chef Andre be represented by c. Greater than is used to denote a situation when something is."more than" another thing. In this scenario,
Chef Andre used more than 3 and one-half cups of flour. This can be represented as C > 3 1/2.
This is the correct answer.
Answer:
10y-12
Step-by-step explanation:
Answer:
T = 49
Step-by-step explanation:
T = w - ma
w = 85
m = 12
a = 3
Plug in the corresponding numbers to the corresponding variables:
T = (85) - (12) * (3)
Remember to follow PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Divisions
Additions
Subtractions
First, multiply, then subtract:
T = 85 - (12 * 3)
T = 85 - 36
T = 49
T = 49 is your answer.
