Answer:
$66
Step-by-step explanation:
It can be convenient to assign a different variable to the amount of money each spent. We can call the amounts spent by Seedevi, Georgia, and Amy "s", "g", and "a", respectively.
The problem statement tells us ...
s = (1/2)g
s = a +6
s + g + a = 258
__
The problem statement asks for the amount Seedevi spent, so we need to find the value of s. It is convenient to write the other variables in terms of s:
g = 2s
a = s -6
Then the sum is ...
s + (2s) +(s -6) = 258
4s = 264 . . . . . . . . . . . add 6, simplify
s = 66 . . . . . . . . . . . . . .divide by 4
Seedevi spent $66.
The first one is congruent by ASA. The second does not have to be congruent, we don’t know enough.
<h2>
6.7 hectometers is equal to "670 meters".</h2>
Step-by-step explanation:
We have,
6.7 hectometers
To convert 6.7 hectometers to meters.
We know that,
1 hectometer = 100 meters
⇒ 1 hm = 100 m
∴ 6.7 hectometers
= 6.7 × 100 meters
= 670 meters
∴ 6.7 hectometers (hm) = 670 meters (m)
Thus, 6.7 hectometers is equal to "670 meters".
You need to add up all the sides to find the perimeter.
Answer:
70 and 71
Step-by-step explanation:
Consecutive means in a row
x is the first number
x+1 is the next number
x+ x+1 = 141
Combine like terms
2x+1 =141
Subtract 1 from each side
2x+1-1=141-1
2x= 140
Divide each side by 2
2x/2 =140/2
x = 70
The two lockers are 70,71
