Answer:
It is a linear equation
solving by substitution method
x + y =6 ------ eqn 1
2x + 4y =20 -------- eqn 2
x = 6 - y ------ eqn 3
putting the value of x from eqn 3. into eqn 2.
2(6-y) +4y =20
12 - 2y + 4y =20
12 +2y =20
2y = 20-12
2y = 8
2y / 2 =8/2
y =4
put the value of y into eqn 3
x =6 - y
x = 6 - 4
x = 2
Therefore x = 2, y= 4
Answer:
C) 13 and 14
Step-by-step explanation:
To find the answer, we need to check for all the options.
A) 11 and 12 = 11 *12 = 132
B) 12 and 13 = 12 *13 = 156
C) 13 and 14 = 13*14 = 182
D) 14 and 15 = 14*15 = 210
In which, C) is true.
It is 182 which falls in 180's
Therefore, answer is C) 13 and 14
Hope this will helpful.
Thank you.
It is 3,998 because if u add it together it is like adding 2,000 +2,000-2
Answer:
23n +13
Step-by-step explanation:
5(5n+2)+(3-2n)
Distribute
25n + 10 +3 -2n
Combine like terms
25n -2n + 10+3
23n +13
