Which equation has the correct sign on the product?
A. (-9)(-9) = -81
B. (-12)(4) = 48
C. (31)(-10) = -310
D. (26)(3) = -78
Answers
Answer:
C. (31)(-10) = -310
Step-by-step explanation:
A. (-9)(-9) = -81
negative times a negative is a positive incorrect sign
B. (-12)(4) = 48
negative times a positive is a negative incorrect sign
C. (31)(-10) = -310
positive times a negative is a negative correct sign
D. (26)(3) = -78
positive times a positive is a positive incorrect sign
Answer:
C. (31)(-10) = -310
Step-by-step explanation:
This equation has the correct sign, because multiplying a positive number and negative number gives you a negative number.
The other answer choices have the wrong signs.
Multiplying 2 negatives together gives a positive, so A is wrong.
Multiplying a negative by a positive gives a negative, so B is wrong as well.
D is wrong because multiplying 2 positive numbers gives a positive number.
So, C is correct.

1)A. 50,25 / 2,15 B. 2x+4(24)=100 2=x
Step-by-step explanation:
B. 2x +4(24)=100
2x+96=100
2x=4
x=2 (2 questions worth 2 pts a piece)
2. x= 5$ bills y= singles
a. 5x+y=36
b. 5(2)+y=36
10 + y=36
y=26 (26 singles)
3. x= sandwich cost y=salad cost
a. 4x+3y=24
b. 4(3.75)+3y = 24
15+3y=24
2y=9
y=4.50 (4.50$ per salad)
4: X = pounds of roast beef, y = pounds of shrimp Roast beef = $4 per pound
Shrimp = $10 per pound
a. Total $96
4 + 10 = 96 b. 4(0)+10=96
10 = 96
= 9.6
The most shrimp Andy can buy is 9.6 lbs

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.
In which step did the student first make a mistake and how can it be corrected?
Step 1; it should be m∠m + m∠n + m∠o = 180 degrees (sum of angles in a triangle)
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)
Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)
Step 2; m∠p − m∠o = 90 degrees (alternate interior angles)
