Answer: x is 5
Step-by-step explanation: 9 x 5 = 5 x 5 + 20
Since an application is 2/7 grams.
Number of applications = 34 ÷ 2/7
= 34 × 7/2
= 17 × 7
= 119
Number of applications = 119
There is one solution in the system of equation
<h3>How to determine the number of solutions?</h3>
The system of equations is given as:
8x=12y-9 and 27y+18x=21
Divide 8x=12y-9 by 8
x = 1/8(12y-9)
Substitute x=1/8(12y-9) in 27y+18x=21
27y + 18 * 1/8(12y-9) =21
Expand
27y + 27y - 20.25 =21
Evaluate the like terms
54y = 41.25
Divide by 54
y = 0.7639
Hence, there is one solution in the system of equation

I think it is
I4.23 x 10 ^4
Answer: 1. [-8, 8]
2. [-27, 27]
Step-by-step explanation:
1. |X|≤8
x≤8 or x>=-8
-8<=x<=8 ==> [-8, 8]
2. |X|≤27
x≤27 or x>=-27
-27<=x<=27 ==> [-27, 27]
