Answer:
84 feet
Step-by-step explanation:
Let the feet be A
1 foot = 0.33 yard
A feet = 28 yards
Cross multiply
A x 0.33 = 28 x 1
Divide both sides by 0.33
A x 0.33/0.33 = 28/0.33
A = 84.84
A = 84 feet
Therefore, there are 84 feet in 28 yards
Answer:
X=the smaller
y=the larger
The bigger of two numbers is four more than the smaller, then:
y=x+4
one more than twice the smaller is the same as the larger, then
1+2x=y
We have the following system of equations:
y=x+4
y=2x+1
We solve this system by equal values method:
x+4=2x+1
x-2x=1-4
-x=-3
x=3
We find the value of "y"now:
y=x+4
y=3+4
y=7
the values of x and y are:
x=3
y=7
Step-by-step explanation:
Its the 2nd answer choice
When solving this equation you get x = -3.
To solve this, simply follow the order of operations for solving.
----> start by dividing both sides by 5
-----> Now you can transform the front side of the equation to use negative exponents.
Since both x and -3 are the powers of x, we can eliminate the 7 and just make the exponents equal.
-3 = x
The answer would be de = 14x but i’m not fully confident in the answer
