A store sells toys in bulk. It sells wooden blocks for $5 a pound and plastic bricks for $10
a pound. How many pounds of wooden blocks and plastic bricks should be used to make a
A 10-pound mixture that would sell for $80?
Answer:
six plastic bricks and four wooden blocks
Step-by-step explanation:
plastic bricks=10
wooden blocks:5
lets make plastic x and wooden y
if we made an eight pound mixture of only plastic bricks, that would get us to 80, but would not be enough weight. if we substitute one x pound for two y, we would have 9 pounds and $80. if we substitute this again, we have ten pounds and $80. we added four wooden blocks, and we took two away from the 8 plastic we had, so that is 6 plastic. so we have 6x and 4y, using the variables I assigned for the blocks above.
For f(x)=2x+1 and g(x)=3x, find (f/g)(x)
Answer:
[tex](f/g)(x)=\frac{2x+1}{3x}[/tex]
General Formulas and Concepts:
Order of Operations: BPEMDASStep-by-step explanation:
Step 1: Define
f(x) = 2x + 1
g(x) = 3x
(f/g)(x) = f(x)/g(x)
Step 2: Solve
Substitute: [tex](f/g)(x)=\frac{2x+1}{3x}[/tex](a) An angle measures 45°. What is the measure of its supplement? (b) An angle measures 62º. What is the measure of its complement?
Answer:
Let the measure of an angle be x then the measure of the complement of the angle is 90 – x and the measure of the supplement of the angle is 180 – x. Example: Find the measure of the complement and supplement of an angle with measure (5x – 2)°.

C =
d =
Answer:
c= 14-7i-zdi
d=14/zi - 7/z - c/zi
Step-by-step explanation:
Solve for c by simplifying both sides of the equation, then isolating the variable.
Solve for d by isolating the variable by dividing each side by factors that dont contain the variable.

-12 + x/5 = -16 ?
I need the steps to learn it ..!
Answer: X = -20
Step-by-step explanation:
-12 + x/5 = -16 ( What you do to one side you do to the other )
+12 +12 ( adding 12 to both sides)
x/5 = -4 ( gives us this )
5 (x/5 = -4) ( I multiplied by 5 to remove the denominator of x )
x = -20 ( get the answer )

2/5 (4x – 3) – 2x = 4/5 - x
Answer:
[tex] \huge \blue{x = \frac{10}{3} } \\ [/tex]
Step-by-step explanation:
[tex] \frac{2}{5} (4x - 3) - 2x = \frac{4}{5} - x \\ [/tex]
Multiply through by 5 to eliminate the fractions
[tex]5 \times \frac{2}{5} (4x - 3) - 2x(5) = 5 \times \frac{4}{5} - 5x \\ 2(4x - 3) - 10x = 4 - 5x \\ 8x - 6 - 10x = 4 - 5x[/tex]
Simplify the terms
[tex] - 2x - 6 = 4 - 5x \\ - 2x + 5x = 6 + 4 \\ 3x = 10[/tex]
Divide both sides by 3
We have the final answer as
[tex]x = \frac{10}{3} \\ [/tex]
