3/5x - 7 = 23
A. x = 40
B. x = 45
C. x = 50
D. x = 55
Answer:
(C) x=50
Step-by-step explanation:
[tex]\frac{3}{5 }x -7=23[/tex]
[tex]\frac{3x}{5} -7=23[/tex]
[tex]\frac{3x}{5} -7+7=23+7[/tex]
[tex]\frac{3x}{5}=30[/tex]
[tex]3x=30* 5[/tex]
[tex]3x=150[/tex]
[tex]x=50[/tex]
Answer:
(C) X = 50
Step-by-step explanation:
(3/5)*x-7 = 23 // - 23
(3/5)*x-23-7 = 0
3/5*x-30 = 0 // + 30
3/5*x = 30 // : 3/5
x = 30/3/5
x = 50 (Sorry if it's wrong)
Mr Lee has a family of 6 people and Mrs Scarlett has a family of 4. They were given 15 kg of chocolate
when they visited a chocolate factory for work. If they decide to share it so that each family
member gets an equal amount, determine the required ratio and hence calculate how much
chocolate Mr Lee and Mrs Scarlett will each take home to their families.
Answer:
Mr Lee would take home 9kg if you dont count Mr Lee and for Mrs. Scarlett it would be 6kg
Step-by-step explanation
Mr Lee has 6 people and Mrs Scarlett has 4 ppl, that's a total of 10 ppl. so you do 15kg/10=1.5kg. That's 1.5 kg each person. Mr Lee has 6 so 6*1.5= 9kg and Mrs Scarlett 4*1.5= 6kg
Robert gets a loan from his bank
he agrees to £6000 at a fixed annual simple interest rate of 7%
He also agrees to pay the loan back over a 10 year period
How much money in total will he have paid back at the end of the 10 years
Answer:
Step-by-step explanation:
the formula for simple interest is:
i = p * r * n
f = p + i
combine the two formulas together and you get f = p + p * r * n.
factor out the p to get f = p * (1 + r * n).
i is the interest
p is the present value or principal
r is the interest rate per time period
n is the number of time periods.
f is the future value
in your problem:
p equals 6000
r = .07 per year
n = 10 years.
the formula becomes 6000 * (1 + .07 * 10) = 6000 * 1.7 = 10200.
if you calculated it separately from i = p * r * n and then f = p * i, you would get the same result.
i = p * r * n becomes i = 6000 * .07 * 10 which becomes 4200.
f = p + i becomes f = 6000 + 4200 which becomes 10200
Answer:
10,200
6,000× .07× 10= 4,200
add that to 6000= 10,200

The first number that'll be gotten based on the information given will be:
= 1/5 × 120
= 24
The second number that will be gotten based on the information given will be:
= 4/5 × 120

"solve for X" any help would be appreciated thankss
Answer:
180° on a straight line
180 = 18x - 54
add 54 to both sides
234 = 18x
X = 234/18
X= 13°
6 X 13 - 5 = 73
12 X 13 - 49 = 107
107 + 73 = 180

A print shop charges a fixed amount per photocopy and gives a 10% discount off the total cost of the photocopies. The total cost is a function of the number of photocopies made. What is the independent variable?
Answer:
the number of photocopies made
Step-by-step explanation:
The wording "a function of the number of photocopies made" tells you that "the number of photocopies made" is the independent variable.
___
The wording "y is a function of x" means x is the independent variable.
Answer:
The Second Choice!
Step-by-step explanation:
X and Y are variables. Y depends on X, remember that! So, the amount of cost depends on the amount of copies, so the cost would be the Y and the amount of copies would be the X! Good luck!!

7z2−38z+15 Select the factors of this quadratic expression.
Answer:
(7z-3)(z-5)
Step-by-step explanation:
7z^2-38z+15
(7z-3)(z-5)
Answer:
(z - 5)(7z - 3)
Step-by-step explanation:
Given
7z² - 38z + 15
Consider the product of the factors of the coefficient of the z² term and the constant term which sum to give the coefficient of the z- term
product = 7 × 15 = 105 and sum = - 38
The factors are - 35 and - 3
Use these factors to split the z- term
7z² - 35z - 3z + 15 ( factor the first/second and third/fourth terms )
= 7z(z - 5) - 3(z - 5) ← factor out (z - 5) from each term
= (z - 5)(7z - 3) ← in factored form
