So first find out how many can be done in 1 minute.
In an equation it would be 3x=42
Divide by 3
x=14
So 14 pushups can be done in 1 minute (congratulations to this person I can barely do one haha)
So now you multiply what you can do in 1 minute by 5 minutes.
14x5= 70 pushups
Answer:
The perimeter of the garden is: "
102 ft. " .
___________________________________________________<u>Note</u>: ___________________________________________________ → P = 2L + 2w ;
in which: "P = perimeter (for which we wish to solve)" ;
"L = length = 10 yds. (given) " ;
"w = width = 7 yds. (given)" .
___________________________________________________ Plug in the given values; and solve for the perimeter, "P" :
→ P = 2L + 2w ;
= 2(10) + 2(7) ;
= 20 + 14 ;
= 34 yds.
____________________________________
The perimeter is: 34 yds.
Now, we are asked to convert this into: "feet (ft.)." .
Note the "exact conversion" : "3 ft. = 1 yd." ;
_________________________________________________ → 34 yds. *
= (34 * 3) ft. =
102 ft._________________________________________________Answer: The perimeter of the garden is: "
102 ft. " .

Step-by-step explanation:
b²- 4ac
Let a=5, b=-2,c=-3
(-2)^2 - 4(5) (-3)
4 +60

She did sell the newspapers for $.25 each at age 80. The equation is referred to as a linear equation in one variable if only one variable is present in the linear equation.
<h3>A linear equation is what?</h3>
It is described as the relationship between two variables, and a straight line results from plotting the graph of the linear equation.
The information provided in the issue is;
One newspaper will set you back $.25.
Other newspapers are $.40 each.
The 100 newspapers were purchased for $28.00.
x is the quantity of newspapers sold for $.25 each.
Y stands for the other newspaper's number.
The total of both newspapers is one hundred.
x+y=100
y=100-x
25x+ 40y=28.00
25x+40(100-x)=2800
25x+4000-40x=2800
-15x+4000=2800
-15x=-1200
x=80
She therefore sold 80 newspapers for $.25 each.
