Answer:
2 1/4
Step-by-step explanation:
We need to see how much clay they used if each person in that group used 3/4 clay. There are 4 people in the group.
=> 3/4 x 4 = 12/4 = 3
Now, we need to see how much clay they used if each person in that group used 1/4 clay. There are 3 people in the group
=> 1/4 x 3 = 3/4
Now, we need to see how much more clay was used.
=>3 - 3/4
=> 3/1 - 3/4
=> Take the LCM of the denominators and make the denominators equal.
=> 12/4 - 3/4
=> 9/4
They used 9/4 more clay.
Since there are no options with 9/4, we need to make this improper fraction into a proper fraction.
=> 9/4 = 2 1/4
They used 2 1/4 more clay.
The value is x= -5/4
<h3>What is LCD?</h3>
The least common denominator is the smallest number of all the common multiples of the denominators when 2 or more fractions are given.
Given:
1/x = 1/5+ 5/4x
1/x = 4x + 25 / 20x
20= 4x +25
4x= -5
x= -5/4

Step-by-step explanation:
Answer:

Step-by-step explanation:
Equation: 
Step 1: Balance both parts of the equation.




Step 2: Reduce 14 from both parts of the equation.


Step 3: Split both sides by 10, because
.


Therefore, x = -1.
First statement is correct. If Sasha reads her novel for 94 minutes, she meets the minimum reading requirement without reading any of the autobiography.
Given,
The rate of reading of a novel by Sasha = 0.8 pages per minute
The rate of reading of autobiography by Sasha = 0.5 pages per minute
The reading requirement of Sasha's English class = atleast 75 pages per week
The given equation: 0.8n + 0.5a ≥ 75
n is the number of minutes she reads the novel
a is the number of minutes she reads the autobiography
Now, let's check the statements:
Statement 1: If Sasha reads her novel for 94 minutes, she meets the minimum reading requirement without reading any of the autobiography.
That is,
0.8 × 94 + 0.5 × 0 ≥ 75
75.2 ≥ 75
This statement satisfies the equation.
Other 4 statement didn't satisfy the equation.
So, first statement is correct.
