Answer:
it gives you -140 if you multiply all of them
To estimate round each number to the closest whole number
7.8 would round to 8
307 would round to 300
8 x 300 = 2400
The answer would be c 2400
Answer:
2/9
Step-by-step explanation:
Given: (12/18)/(12/4)
Simplify denominator: (12/18)/3
Use rule: (12/18)/3=12/(18*3)=12/54
Simplify: 12/54 -> 6/27 -> 2/9
So 2/9 is the answer
Answer:
The numbers are 20 and - 13
Step-by-step explanation:
Given as ;
The sum of two numbers = 7
Two times a number and three times another number = 13
So ,Let The first number = x
and The second number = y
According to question
x + y = 7 and ...A
2 × x + 3 × y = 1 ....B
Multiply eq A by 2
I.e 2 × ( x + y ) = 2 × 7
Or, 2 × x + 2 × y = 14
Now solve the both equation
( 2 × x + 3 × y ) - ( 2 × x + 2 × y ) = 1 - 14
Or. ( 2 x - 2 x ) + ( 3 y - 2 y ) = - 13
Or, 0 + y = - 13
∴ y = - 13
Put The value of y in eq A
x + y = 7
Or , x = 7 - y
Or, x = 7 - ( - 13 )
so, x = 7 + 13
∴ x =20
Hence The numbers are 20 and - 13 Answer
10.49 i belive is the answer
