Put the numbers given accordingly in the equation
bracket means multiply
2(-2)-5(5)-3(-2)
=-4-25+6
=-23
a. -23
Answer:
Whether the answer is positive or negative depends on the number of positive and negative values in the question. The rules are exactly the same as to whether an answer is positive or negative. In the case of fractions, the rules for multiplying fractions apply as well (the numerators in the expression multiply to produce the product's numerator; the denominators in the expression multiply to produce the product's denominator) and the answer should be reduced to lowest terms.
If there is an odd number of negative terms, the answer will be negative.
If there is an even number of negative terms, the answer will be positive.
Answer:
7x
Step-by-step explanation:
This quantity is the same as obtained when dividing 14x by 2: 7x
Answer:
x = 29
Step-by-step explanation:
Follow the directions: substitute 13 for y in the first equation.
x + 13 = 42
Subtract 13 from both sides of the equation.
x +13 -13 = 42 -13
x = 29
