Answer:
the third expression
Step-by-step explanation:
x=10.8
(x2 / 18) + 33.52
10.8 x 10.8=116.64
116.64 divide by 18=6.48
6.48 + 33.52=40
Answer:
1.15p + 285 = 5.84
Step-by-step explanation:
This problem has two equations. Total cost and Total pounds. The cost and the pounds
p = apple pounds
b = banana pounds
<u>Cost</u>
1.90p + .75b = 5.84
<u>Pounds</u>
p + b = 3.8
<u>Now we use the substitute method for system of equations to solve</u>
p + b = 3.8
b = -p + 3.8
<u>Now that we know what b equals, substitute is for b in the cost equation.</u>
1.90p + .75b = 5.84
1.90p + .75(-p+3.8) = 5.84
<u>distribute / multiply .75 by (-p+3.8)</u>
1.90p + -.75p + 2.85 = 5.84
<u>Combine the p values</u>
1.15p + 285 = 5.84
The first one and the second??
Answer:
A
Step-by-step explanation:
Null means nothing, or zero.
In the case of matrix, a null matrix is a matrix where all its elements are zeros.
They can be of any order, 2 x 3 matrix, 2 x 4 matrix, 2 x 2 matrix etc.
A matrix has a diagonal and other values (non-diagonal). When diagonal is 0 only, and not other, its is still not null. When all the values of a matrix are 0, all the elements are 0, then we call that Null Matrix.
It is equivalent to Zero (0) in the number system.
Correct answer choice is A
Answer: 44 dollars
Step-by-step explanation:
so there is two ways to do this so ill show you both and you can see which one is easier for you!
method 1- divide the total amount of tickets by the amount with the cost. Then multiply that number by the cost
20/5=4 4*11=44
method 2- divide the money by the number with the cost. Then multiply it by the total amount of tickets.
11/5=2.2 2.2*20=44
