Answer:
Some equations are easy to solve in your head. If the numbers are easy to work with, you just have to figure out what question you need to answer. For example, to solve x + 8 = 12, you have to determine what number can be added to 8 in order to have a sum of 12. In this case, x must be equal to 4.
Other equations, however, are much harder to solve using mental math. Equations that have lots of negative numbers, large numbers, fractions, or decimals can be difficult to solve in your head. That's why there is a system, called an algorithm, for solving these equations.
An algorithm is just a step-by-step process for solving problems. The algorithm for solving equations is based on a very important property called the property of equality, which says that whatever is done to one side of the equation must also be done to the other side.
The algorithm for solving equations has four steps:
Locate the variable.
Determine what operation is being done to the variable.
Do the inverse operation on both sides of the equation.
Check your solution using substitution.
Remember that the goal of solving an equation is to determine what value of the variable will make the sentence true. This means you need to find what the variable is equal to. That's why the first step, although it may seem easy, is so important. You need to start by locating the variable in the equation. Take a look at Ondi's equation from above:
n - 1.4 = 3.7
In this case, the variable is n, and it's on the left side of the equation. That was easy! Now for the second step. Remember that the goal is to figure out what the variable is equal to when it's by itself. So in the second step, you have to identify what is being done to the variable in the equation. If you look at the equation above, you can see that 1.4 is being subtracted from n. The second step is complete!
The third step is when you actually start working with the equation. You're going to do the opposite of what is already being done to the variable. For example, if a number is added, you're going to subtract. If a number is subtracted, you're going to add. This will help you get the variable by itself on one side of the equation. Then you'll know what the variable is equal to!
In the equation, 1.4 is being subtracted from n. So you're going to do the opposite and add 1.4. Remember that the property of equality says that if you do something to one side of the equation, you must do it to the other side as well. Take a look:
n - 1.4 + 1.4 = 3.7 + 1.4
Can you see what is going to happen on the left side of the equation? Subtracting 1.4 and adding 1.4 cancel each other out, leaving you with just n. That's because subtraction and addition are inverse operations, which means they undo each other.
So the left side of the equation simplifies to the variable n. What will happen on the right side? The constants 3.7 and 1.4 will combine to give you 5.1.
n = 5.1
The fourth and final step of the algorithm is to check the solution using substitution. Substitute the value of 5.1 in for n in the original equation to see if the sentence is true:
n - 1.4 = 3.7
5.1 - 1.4 = 3.7
3.7 = 3.7
Yes! This statement is true, so the solution is correct!

To make a big batch of cookies for her father, Annmarie needs 1 1 4 pounds of chocolate chips, 3 4 pounds of walnuts, and 12 ounces of raisins. How many ounces of these three ingredients does she need in all?.
She will need 68 ounces in total for all three ingredients.
What will be the total ounces for all three ingredients?It is given that
For chocolate chips, she has = [tex]\dfrac{11}{4}[/tex] pounds
For walnuts, she has = [tex]\dfrac{3}{4}[/tex] pounds
For raisins, she has= 12 ounces
We know that,
[tex]\rm 1 \ pound = 16 \ ounces[/tex]
[tex]\rm For \ chocolate \ chips, she\ has = \dfrac{11}{4} \times 16 }=44 \ ounces[/tex]
[tex]\rm For \ walnuts,\ she\ has = \dfrac{3}{4} \times 16 }=12\ ounces[/tex]
[tex]\rm For\ raisins, she \ has= 12\ ounces[/tex]
so the total number of ounces she has will be the sum of all
[tex]=44+12+12 =68\ ounces[/tex]
Thus she will need 68 ounces in total for all three ingredients.

Problem 3
Answer: Choice A and Choice C
-----------------------
Explanation:
Think of stacks of coins. Let's say we had 2 stacks of 10 quarters each. The quarters are identical, so they must produce identical volumes. Those sub-volumes then add up to the same volume for each stack. Now imagine one stack is perfectly aligned and the other stack is a bit crooked. Has the volume changed for the crooked stack? No, it hasn't. We're still dealing with the same amount of coins and they yield the same volume.
For more information, check out Cavalieri's Principle.
With all that in mind, this leads us to choice C. If the bases are the same, and so are the heights, then we must be dealing with the same volumes.
On the other hand, if one base is wider (while the heights are still equal) then the wider based block is going to have more volume. This leads us to choice A.
Hope makes 3 group of shapes
What Larger group to the shapes in a and B belong in
The shapes in the three groups are quadrilaterals
The shapes in group A and B belong to parallelograms and rectangles
How to determine the shapes?From the complete question, we can see that the shapes in the group A have opposite parallel sides and the angle between the adjacent sides is not 90 degrees.,
This means that the shapes in group A are parallelograms
Similarly, the shapes in the group B have opposite parallel sides and the angle between the adjacent sides is 90 degrees.
This means that the shapes in group A are rectangles
Hence, the shapes in group A and B belong to parallelograms and rectangles

Review Question: 5) f(x) = 2xsquared + 7x - 15 find f(-8)
Answer:
f(-8) = 57
Step-by-step explanation:
When x = - 8
f(-8) = 2 x (-8)² + 7 x (-8) - 15
f(-8) = 2 x 64 - 56 - 15
f(-8) = 128 - 56 - 15
f(-8) = 128 - 71
f(-8) = 57
[tex]\sf f(x) = 2x^2 + 7x - 1[/tex]
Just substitute the value of x as (-8) .
[tex]\sf f(-8) = 2(-8)^2 + 7(-8) - 15[/tex]
[tex]\sf f(-8) = 2(64) - 7(8) - 15[/tex]
