Step-by-step explanation:
First, transform 8 feet and 10 feet into inches so we can work with the same measurements
8 * 12 = 96 in
10 * 12 = 120 in
Next find the patio rectangle area.
96 * 120 = 11520 in^2
Now find the paving block area
4 * 8 = 32 in^2
Now, find out how many paving blocks will go into the patio rectangle area.
11520 / 32 = 360
The minimum number is 360 paving blocks
Answer:
b - 9 = 2 I believe would be it
I believe 4(x - 3)=32 could help I haven’t done an equation from the unit in months so hopefully that looks familiar to you.
(2,-2) would be the answer I think
Answer:
The number of once is 9.1
The number of hundreds is 8.9
Step-by-step explanation:
Given as :
The total of digits having ones and hundreds = 900
The sum of digits = 18
Let The number of ones digit = O
And The number of hundreds digit = H
So, According to question
H + O = 18 .........1
100 × H + 1 × O = 900 ........2
Solving the equation
( 100 × H - H ) + ( O - O ) = 900 - 18
Or, 99 H + 0 = 882
Or , 99 H = 882
∴ H = 
I.e H = 8.9
Put the value of H in eq 1
So, O = 18 - H
I.e O = 18 - 8.9
∴ O = 9.1
So, number of once = 9.1
number of hundreds = 8.9
Hence The number of once is 9.1 and The number of hundreds is 8.9
