Answer:
a = 0.3
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
(5.3a - 0.8) - (1.6 - 4.7a) = 2a - (a - 0.3)
Step 2: Solve for a
Distribute negative: 5.3a - 0.8 - 1.6 + 4.7a = 2a - a + 0.3Combine like terms: 10a - 2.4 = a + 0.3Subtract a on both sides: 9a - 2.4 = 0.3Add 2.4 on both sides: 9a = 2.7Divide 9 on both sides: a = 0.3Step 3: Check
Plug in a to verify it's a solution.
Substitute: (5.3(0.3) - 0.8) - (1.6 - 4.7(0.3)) = 2(0.3) - (0.3 - 0.3)Multiply: (1.59 - 0.8) - (1.6 - 1.41) = 0.6 - 0Subtract: 0.79 - 0.19 = 0.6Subtract: 0.6 = 0.6Here we see that 0.6 does indeed equal 0.6.
∴ a = 0.3 is a solution of the equation.

6. The function (3) - 44x represents the number of jumping jacks j(x) you can do in x minutes. How many
jumping jacks can you do in 5 minutes?
2 149 jumping jacks
c220 jumping jacks
b. 239 jumping jacks
d 8jumping jacks
Answers
Answer:
We can do 220 jumping jacks in 5 minutes.
Step-by-step explanation:
We are given the function:
[tex]j(x) =44x[/tex]
Note: Considering there is typing mistake and the function is: j(x)=4x
where x is minutes
We need to find How many jumping jacks can you do in 5 minutes.
So, here x=5
Now putting value of x in the given function
[tex]j(x) = 44x\\Put \ x=5\\j(5)=44(5)\\j(5)=220[/tex]
So, we can do 220 jumping jacks in 5 minutes.

A.

Answers
Answer:
The ratio is 34/22, or in simplest form, 17/11.
Step-by-step explanation:
We write the ratio with the number of rolls greater than three on top and the number of rolls less than or equal to 3 on bottom:
34/(56-34)
We have to subtract 34 from 56 to find out how many rolls were less than or equal to 3.
34/22
Both are divisible by 2, so we have 17/11.
