Answer:
84
Step-by-step explanation:
Start by isolating the X.
1 :
x + 1 ¾ = 2 4/8
- 1 ¾ - 1 ¾
2 :
x = (2 4/8) - (1 ¾)
3 :
In order to subtract the fractions, you need to find a common denominator.
The common denominator can be found by multiplying the two denominators together.
4 x 8 = 32
4 :
Rewrite each fraction as an equivalent fraction with a denominator of 32.
4/8 —> (4 x 4)/(8 x 4) —> 16/32
¾ —> (3 x 8)/(4 x 8) —> 24/32
5 :
Subtract the numerators. Simplify the answer if needed.
16/32 - 24/32
16 - 24 = -8
-8/32 —> (-8/4)/(32/4) —> -2/4
-2/4 —> (-2/2)/(4/2) —> - ½
6 :
(2 - 1) - ½ —> 1 - ½ = ½
Final answer : X = ½ :)
Answer:
l=200 yard
w=70 yard
Step-by-step explanation:
let width =w
length l=2w+60
then perimeter P=2(l+w)=2(2w+60+w)=540
3w+60=270
3 w=270-60=210
w=70
l=2*70+60=200
Answer:
He would need
cups of salt.
Step-by-step explanation:
We are given that,
The recipe requires
cups of flour and
teaspoons of salr.
As Nick wants to make the recipe using 1 cup.
Let the amount of salt needed = x
The ratio of the flour and salt will be same.
So, we have,

i.e. 
i.e. 
i.e. 
Thus, he would need
cups of salt if 1 cup of flour is used.
