You multiply or divide integers just as you do whole numbers, except you must keep track of the signs. To multiply or divide signed integers, always multiply or divide the absolute values and use these rules to determine the sign of the answer.

<span>
When you multiply two integers with the same signs, the result is always positive. Just multiply the absolute values and make the answer positive.</span>

<span>Positive x positive = positive 
Negative x negative = positive</span>

<span>When you multiply two integers with different signs, the result is always negative. Just multiply the absolute values and make the answer negative.</span>

<span>Positive x negative = negative
Negative x positive = negative</span>

<span>When you divide two integers with the same sign, the result is always positive. Just divide the absolute values and make the answer positive.</span>

<span>Positive ÷ positive = positive
Negative ÷ negative = positive</span>

<span>When you divide two integers with different signs, the result is always negative. Just divide the absolute values and make the answer negative.</span>

<span>Positive ÷ negative = negative
Negative ÷ positive = negative</span>

a grocer stacks apples in a pyramid-like stack whose rectangular base is 7 apples by 5 apples. each apple above the first level
g100num [7]

The arrangement of the apples in the stack is in a sequence that can be

used to find the number of apples in each row and in the stack.

Correct response:

  • The number of apples in the stack are <u>85 apples</u>

<h3>How to find the sum of a sequence</h3>

The given parameters are;

Dimensions of apples in the rectangular base = 7 apples by 5 apples

Number of apples on which each apple above rests = 4 apples

Required:

The number of apples in the stack.

Solution:

The dimensions, length and width of the apples in each row decreases

by 1 compared to the row on which the apple rests, as follows;

In the base, the dimension = 7 by 5

In the row directly above, the dimension = (7 - 1) by (5 - 1)

The number of apples sequence continues and is completed by a singles row of apples at the top, from which gives;

Number of apples in the stack = 7 × 5 + 6 × 4 + 5 × 3 + 4 × 2 + 3 × 1 = 85

  • The number of apples in the tack = <u>85 apples</u>

Dovator [93]

Answer:

D. no solution

Step-by-step explanation:

h-z=3(1)

h=3+z(minus z from both side)

put in the second equation

-3h,+3z=6(2)

-3(3+z)+3z=6

-9-3z+3z=6

-9=6( not true)

so the equation doesn't have a solution.
