Ed use 3 2/3 cups of peanut butter and 2 cups of powdered sugar to make 1 batch of peanut butter fudge. How much more peanut butter will Ed use than powdered sugar to make 3 batches of fudge?
Answers
Answer:
Ed will use 5 more peanut butter than powdered sugar to make 3 batches of fudge(11-6=5)
Step-by-step explanation:
3 2/3 cups of peanut butter (x)
2 cups of powdered sugar(y)
for every one batch you need 2 cups, and for 3 batches you need 6 cups of powdered sugar(2*3=6)
and for every batch you need 32/3 cups of peanut butter and for three batches you need (3 2/3 *3)= 11/3 *3=33/3=11 cups of peanut butter to make the fudge
Ed will use 5 more peanut butter than powdered sugar to make 3 batches of fudge(11-6=5)

The multiplicative rate of change that should be in Hal’s function = 49/50=0.98
=9.8×10⁻¹
Explanation
The investment of $10,000 decreases by 2% every year. So the following year is usually (100 - 2)=98% of the previous year. This is a geometric progression.
In this case the first term = 10000
The second term = 98% × 10000 = 9800.
The common ratio = 9800/10000=49/50
The multiplicative rate of change that should be in Hal’s function = 49/50=0.98.
The equation of the exponential rate would be;
10,000ₓ0.98ⁿ.
where n is the number years.

Step-by-step explanation:
1). A worker bee has the mass = 0.00011 kg
In scientific notation we can convert the mass of bee as,
0.00011 =
=
Since 1.1 ≈ 1,
Therefore, 1.1 × 10⁻⁴ ≈ 1 × 10⁻⁴ kg
Option (A) is the answer.
2). An African elephant has a mass = 8139 kg
In scientific notation,
8139 = 8.139 × 10³
Since, 8.139 ≈ 8
Therefore, 8139 kg = 8.139 × 10³ kg
Option (A) is the answer.

Write an equation in slope-intercept form that is perpendicular to y = -7x + 3 and passing through (14.1).
Answers
Answer:
y = 1/7x -1
Step-by-step explanation:
1) Find the slope.
- In this case, the equation given is in simplest form so you can easily come to the conclusion that '-7' is the slope. But, since the math question wants a slope-intercept form in perpendicular form, the slope would actually be 1/7.
2) Use the point-slope form and substitute the values available. Then solve.
m (slope) = 1/7
(a, b) = (14, 1)
y - b = m(x - a)
y - 1 = 1/7(x - 14)
y - 1 = 1/7x - 2
y = 1/7x - 1
The result is your answer.

It's x = 12 (d)
Step-by-step explanation:
Subtract 4 on both sides: (16 - 4) - x = (4 - 4)
12 - x = 0
Then add x on both sides: 12 (- x + x) = (0 + x)
12 = x
Therefore x = 12
-3a + 4 = -14
What the answer to this
Answers
Answer:
-6
Step-by-step explanation:
-3a + 4 = -14
-3a = -14 - 4
-3a = -18
a = -18 / 3
a = -6
Answer:
a = 6
Step-by-step explanation:
Step 1: Subtract 4 from both sides.
-3a + 4 - 4 = -14 - 4
+4 and -4 cancel out.
Step 2: Subtract 4 from -14 to get -18.
-3a = -18
Step 3: Divide both sides by -3.
a = -18/-3
Step 4: Divide -18 by -3 to get 6.
a = 6
Let's check our work by substituting a for 6.
-3(6) + 4 = -14
Multiply -3 by 6 to get -18.
-18 + 4 = -14
Add -18 and 4 to get -14.
-14 = -14
This is true, so a = 6.

Choose a missing numbers that make the following expression equivalent ____x + 14 and 7 ( 5 x + _____ )
Answers
Answer:
35x + 14 and 7(5x + 2)
Step-by-step explanation:
We have to find the missing values that would also make both expressions equivalent.
_x + 14 and 7(5x + _ )
In the expression, there are some similarities with the placement of the numbers and variables.
Let find the value of the number next to "x".
You can see that we have to use the distributive property to solve the right expression, and once we do so, we can find our first value.
Use the distributive property:
7(5x)
35x
Now we know that our first value is 35x.
To find our second value, we see that in the first equation it is "14", so we need a number that can be multiplied by 7 to make 14.
7 · 2 = 14
Our second number would be 2.
Your final answer would be: 35x + 14 and 7(5x + 2)
Once you use the distributive property for the second expression, you would get an equivalent expression as the first one.

Step-by-step explanation:

-4x=18 |*(-1)
4x=18 | /2
2x=9 |/2
x=9/2 or 4.5
Answer:
x = 4.5
Step-by-step explanation:
Subtract 5 from BOTH sides to start with:
5-5 = 0 (5 cancels out on left side) 23-5 = 18
New Equation: -4x = 18
Divide BOTH sides by -4
4 cancels out (x is left) 18/4 = 4.5
New: x = 4.5

f(x)=6x+4. Find the inverse of f(x).
Answers
Answer:
c
Step-by-step explanation:
f(x)=6x+4
y=6x+4
x=6y+4
6y=x-4
y=(x-4)/6
f^-1(x)=(x-4)/6
Answer is Option-C
How to find Inverse Function:
1. First, replace f(x) with y. This is done to make the rest of the process easier.
2. Replace every x with a y and replace every y with an x.
3. Solve the equation from Step 2 for y.
(Here), Given
f(x) = 6x + 4
Let's inverse function be y.
y = 6x + 4
First step is to switch the positions of x and y.
Inverse: x = 6y + 4
x - 4 = 6y
=> y = (1/6) * (x - 4)
Option-C
