Answer:
Options A, C and F are correct
Step-by-step explanation:
The expression in the question has a slight error in it
<em>"17.75x + 24 = 18.95x + 18"</em> is mearnt to be 17.95x + 24 = 18.95x + 18
Options A, C and F is correct
Given the expression for the situation
17.95x + 24 = 18.95x + 18
collect like terms
17.95x-18.95x=18-24
-x=-6
divide both sides by -1 and solve for x we have
x=6
The girls will both pay the same if they buy six pairs of pants and one sweater.
Solving an equation like this means to find the value of the variable. Here, the variable is x. Solve the left side normally.
Given: 1/3(9 - 6x) = -11
Distribute: 1/3(9) + 1/3(-6x) = -11
When operating with constant numbers on a variable term, apply affects of the operation on the coefficient. So, 1/3(-6x) = -2x.
3 - 2x = -11
Isolate the variable: 3 - 3 - 2x = -11 - 3
-2x = -14
Since these are both negative, we can convert them both to being positive.
2x = 14
Simplify: 2x/2 = 14/2
<u>x = 7</u>
Rewriting 278-159=119, we get 159 + 119 = 278. The first term is 159. If we add 119 once, we get 278; if we add 119 again, we get 397; and so on. This is an arithmetic sequence.
Answer:
Option 4
Step-by-step explanation:
Functions must pass the Vertical Line Test (VLT). Every input has to have exactly one output.
To determine the weight of the bodybuilder and since we are given the BMI or the boddy mass index and the height, it would be best to use these values. BMI is a measurement that is used to scaled body fat based in the weight and the height of adult women and men. It is calculated by the equation as follows:
BMI = 703 (mass in lb / height in inches^2)
Given:
height = 6ft 4in
BMI = 27.6
Solution:
height = 6 ft ( 12 in /1 ft ) + 4 in = 76 in
BMI = 703 (mass in lb / height in inches^2)
27.6 = 703 (mass in lb / 76^2)
mass = 226.77 lb or 103.08 kg
