Answer:
x+4=20 is a solution to 5(x+4)=100.
Step-by-step explanation:
Following PEMDAS, divide 5 from both sides of the equation 5(x+4)=100, and you have x+4=20 remaining.
This means that both equations have the same solution.
Hey! a+5=7 means that a is the variable, while seven is the answer. My technique is like this: 7-5=2 You need to subtract the numbers you already have. This only works for addition! Hope this helps :) !
The problem uses the concept of Combination where there are number of members chosen from a group and there order is not important. Thus, the expression that would best describe the given above is 30C6 which means the combination of 30 taken 6. The numerical value for this is 593775.
Answer is -10
(x-3)-2(x+6)= -5
x-3-2x-12= -5
-x= -5+12+3
-x=10
x= -10
I think its C. 7x3 = 21. 7x18 = 126. 9x7 = 63
If you all that the answer its 210. If you estimate what that little part above the farthest to the right shape, I'd say its near 18 to 21. Then add 210 with either numbers 18 through 21, it would be close to 227 square meters.
