Answer:
QR=RS=QS=29
Step-by-step explanation:
Given QRS is an equilateral triangle, thus all the three sides of the given triangle will be equal.
Also, from the given statement, we have
QR=2x-7, RS=5x-61 and QS=11+X
Now, As all the sides of the triangle are equal, therefore
QR=RS=QS
⇒QR=RS
⇒2x-7=5x-61
⇒-7+61=5x-2x
⇒54=3x
⇒x=18
Thus, the measure of QR=2(18)-7=29,RS=5(18)-61=29 and QS=11+18=29.
Answer: 6 gallons
Step-by-step explanation:
4 gallons of water for 30 plants
turn into ratio
4:30
simplify
2:15
multiply both sides by 3 to get 45 plants
6:45
6 gallons for 45 plants
Answer:
Step-by-step explanation:
8b - 7 = 7b - 2
Bringing like terms on one side
8b - 7b = - 2 + 7
B = 5
-12 + 5k = 15 - 4k
Bringing like terms on one side
5k + 4k = 15 + 12
9k = 27
k = 27/9 = 3
Answer:
You can calculate the area of the circle
We know the formula is: 
And if diammeter is 800, then the radio is a half: 400
We replace:
feet
So now we can divide:
502654/1000 = 502,654 minutes
Answer:
39
____________________________________________
Step-by-step explanation:
Since you want to find the variable x all you have to do is simple subtraction.
The two numbers (61 and 22). Subtract those numbers and you get 39. Now it wants you to round to the jearest hundredth but there is no hundreds place so we can round to the nearest tenth. Which would be 30! Hope it helped... :)!
Bye! I did this same answer on this same problem that you posted again.
