Answer:
x>3
Step-by-step explanation:
Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
We will be using simultaneous equations to solve this problem.
Let's establish the two equations we will be using to solve the problem.
Let Andrew's current age = a
Let Andrew's son's current age = s
Equation No. 1 -
a = 3s
Equation No. 2 -
a - 10 = 5s
To begin with, we will substitute the value of ( a ) from the first equation into the second equation to solve for ( s ).
Equation No. 2 -
a - 10 = 5s
( 3s ) - 10 = 5s
3s - 5s = 10
- 2s = 10
s = 10 / - 2
s = - 5
Next we will substitute the value of ( s ) from the second equation into the first equation to solve for ( a ).
Equation No. 1 -
a = 3s
a = 3 ( - 5 )
a = - 15
FINAL ANSWER:
Therefore, the present age of Andrew is - 15 and the present age of Andrew's son's is - 5.
It isn't possible for someone to be negative years old, but this is the answer that I ibtained from the equations.
Hope this helps! :)
Have a lovely day! <3
Round to the nearest ten. Look at the ones value, it is a 0. Because 0 is less than 5, round down
913610 rounded to the nearest ten is 913610

Answer:
Her estimate is reasonable.She can make 25 completed centerpieces
Step-by-step explanation:
Estimate 20 flowers per centerpiece. 430 flowers divided by 20 flowers per centerpiece.
430 /20 is approximately 21 centerpieces. Her estimate is reasonable.
430/20 Divide the top and bottom by 10
43/2 is 21*2 = 42 with 1 left over 21 1/2
We know we underestimated when we rounded 17 to 20. Se we are a little under with 21.5
Exact answer:
430÷17
17 goes into 43 2 times (17*2 = 34 43-34 = 9 left over)
17 goes into 90 5 time (17*5 = 85 90-85 = 5 left over)
She can make 25 completed center pieces
