Step-by-step explanation:
2(x+7)=72 no, because this only changes the value on the right side. so this equation is not about the same equality anymore.
x+7=18 yes, because both sides were transformed by the same operation (division by 2). the equality is still maintained.
2x+7=36 no, because 2x+7 is NOT equal to 2(x+7). resolving 2(x+7) is 2x+14.
x+14=36 no, because again, x+14 is NOT equal to 2(x+7).
(2×x) + (2×7) = 36 yes, because the left side is a valid transformation of 2(x+7).
2x+14=36 yes, because the left side is a valid transformation of 2(x+7).

Lena's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Lena S4.10 per pound, and type B coffee costs $5.95 per
pound. This month's blend used twice as many pounds of type B coffee as type A, for a total cost of $336.00. How many pounds of type A coffee were used?
Answers
Answer: Just bought 21 pounds of coffee A
Step-by-step explanation:
We know that she consumed twice as many pounds of Type B coffee as type A.Then let the total number of cafe feet A=x ; then the number of cafe feet B=2x . We also know that the total number of feet cost $336And the fact that one pound of coffee A costs $ 4.1 ; and one pound of coffee B costs $ 5.95 Then :[tex]\large \boldsymbol {} 2x\cdot 5,95 +x\cdot 4,1 =336 \\\\ 11,9x+4,1x=336 \\\\ 16x=336 \\\\ \boxed{x=21}[/tex]Sonia works at a bakery. The function f(x) represents the amount of money Sonia earns per loaf, where x is the number of loaves she makes. The function g(x) represents the number of bread loaves Sonia bakes per hour, where x is the number of hours she works. Show all work to find f(g(x)), and explain what f(g(x)) represents.
f(x) = 8^2 +4
g of x equals the square root of the quantity 2 x cubed
Answers
Answer:
[tex] f(x)=8x^2+4\\ g(x)=\sqrt{2x^3}\\ f(g(x))=8((\sqrt{2x^3})^2)+4\\=16x^3+4\\=4(4x^3+1)[/tex]
The function f(g(x)) will be f(g(x)) = 4(4x³ + 1) where 'x' is the number of hours.
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The functions are given below.
f(x) = 8x² + 4
g(x) = √(2x³)
The function f(g(x)) is calculated as,
f(g(x)) = 8[√(2x³)]² + 4
f(g(x)) = 8[√(2x³)]² + 4
f(g(x)) = 16x³ + 4
f(g(x)) = 4(4x³ + 1)
The function f(g(x)) will be f(g(x)) = 4(4x³ + 1) where 'x' is the number of hours.

You bought a package of paper for $3 and some pencils for $2 each at the school store. You paid $15 for everything that you bought. How many pencils did you buy?
Answers
Answer:
6 pencils
Step-by-step explanation:
Total cost = paper * cost of a package + pencils * cost of a pencils
We bought 1 pack of paper at 3 dollars and p pencils at 2 dollars
15 = 1*3 + p*2
15 = 3+2p
Subtract 3 from each side
15-3 = 3+2p-3
12 = 2p
Divide by 2
12/2 = 2p/2
6 = p

Answer:
c)2:1..................
Answer:
C
Step-by-step explanation:
Find the distance of AB:
Distance formula: [tex]\sqrt{[(-8)-(-2)]^2+(9-1)^2}[/tex]
[tex]\sqrt{(-6)^2+(8)^2}=\sqrt{36+64}=\sqrt{100}=10 units[/tex]
