The final answer will be a 3x3 matrix. So you'll have 3 rows and 3 columns.
Along row one, the values are: 10, 15, 20
Along row two, the values are: 45, -5, -35
Along row three, the values are: 55, 25, -15
all of which make up the final answer. Each value in bold is the result of multiplying the outer 5 by each value inside the original matrix given. In a sense, it's like using the distributive property, though we wont be adding any of the values (everything stays separated).

Step-by-step explanation:
sorry do not .know
In this number 800 is 10 times
as much as what number.
To answer the query we can
illustrate this problem into a mathematical equation of
<span><span>
1.
</span>10 x N = 800</span>
<span><span>
2.
</span><span> 10N = 800</span></span>
<span><span>3.
</span><span> N = 800/10</span></span>
<span><span>
4.
</span><span> N = 80</span></span>
Hence, the number is 80.
Its B! They have to multiply to get 96 and b is the only one that also adds to get 40
Answer:
Kailee bought 26 of 49-cents stamps and 10 of 21-cents stamps.
Step-by-step explanation:
Given:
Total Money paid for stamps = $14.84
Let the number of 49-cents stamps be x.
Also Let the number of 21-cents stamps be y.
Now Total Money paid is equal to sum of number of 49-cents stamps and number of 21-cents stamps.
100 cents = 1$
So 49 cents = $0.49
and 21 cents = $0.21
Hence equation be framed as;
Also Given:
number of .49-cents stamps was four less then three times the number of 21-cent stamps.
hence we can say that;
Now Substituting the value of equation 2 in equation 1 we get;
Now substituting the value of y in equation 2 we get;
Hence Kailee bought 26 of 49-cents stamps and 10 of 21-cents stamps.
