Answer:
The largest number is 218.
Step-by-step explanation:
The given numbers are 2,5,8,9,10, given operations are ×,+,+,- and exactly one pair of parentheses.
We need to find the largest number which can be form by using given information.
We know that multiplication of two lager numbers is greater than their addition.
We need to multiply 10 and sum of 9,8,5. To get the largest number we have subtract the smallest number.
So, the largest possible number is defined by the expression




Therefore, the largest number is 218.
Since 90 degrees is 1/4 of a circle then 1/4 of 12 is 12/4 = 3m^2
Answer:
Step-by-step explanation:
The system of equations given are:
5x - y + z = -6 ------------- i
2x + 7y + 3z = 8 ---------- ii
x + 2z = 6 ----------------- iii
Let us deal with equation i and ii first since they have 3 variables x, y and z;
5x - y + z = -6 x 7
2x + 7y + 3z = 8 x 1
35x - 7y + 7z = -42 ---- iv
2x + 7y + 3z = 8 ---- v
Add equation iv and v;
37x + 10z = -34 ------vi
So, let us solve equation vi and iii:
x + 2z = 6 - ---------- iii x 10
37x + 10z = -34 --- iv x 2
10x + 20z = 60 vi
74x + 20z = -68 vii
Subtract vi - vii;
-64x = 128
x = -2
So; put x = -2 into iii;
x + 2z = 6
-2 + 2z = 6
2z = 6 + 2 = 8
z = 4
Put x = -2 and z = 4 into equation i;
5(-2) - y + 4 = - 6
-10 -y +4 = -6
-6 - y = -6
-y = 0
y = 0
Answer:
It is 3
