Step-by-step explanation:
Six girls share 5 1/3 pounds of pretzel each one receive the same amount. However, Sue only eats half of her pretzels and leaves the uneaten on the plate . How many pounds does sue leave on her plate?
Answer:
4/9 pounds
Step-by-step explanation:
5 1/3 pounds of pretzels divided equally for 6 girls would mean that each girl gets 8/9 pounds of pretzel.
If Sue ate half of the 8/9 pounds, that would equal to 4/9 pounds of pretzel.
the solution to 5/2 x-7 =3/4 x +14
Answer:
x = 12.
Step-by-step explanation:
5/2x - 7 = 3/4x + 14.
put the like terms together keeping in mind that when a number crosses the equal sign it changes its sign and it acquires the opposite sign.
5/2x - 3/4x = 14 + 7
7/4x = 21.
divide both sides by the reciprocal of 7/4, the number next to the unknown
so x = 21 ×4/7
x = 12.
is -2 a solution for 7x+3=-17-3x ?
Answer:
yes -2 is the correct answer
Step-by-step explanation:
7x+3=-17-3x
7x+3x=-17-3
10x=-20
x=-20/10
x=-2
Answer:
[tex]\boxed{\bold{\huge{\boxed{\sf Yes.}}}}[/tex]

find the area of the shape
Answer:
546
Step-by-step explanation:
Formula: 0.5*[sum of parallel sides] *height
Answer:
636 in.²
Step-by-step explanation:
First divide the shape into three pieces, you will get a triangle and two rectangles, the base of the triangle is 30 in. The height is 8 in. Multiply 30×8 to get 240 and then divide by two to get 120. Next the rectangle on top has sides that are 24 in. and 8 in. You will get 192. Lastly the rectangle on the bottom has sides of 54 in. and 6 in. For this you will get 324. Finally you add up 120+192+324 to get 636 in.²

Given the graphs of y = f(x) and y = g(x),
g(x) = f(x)
expresses g(x) in terms of f(x).
Step-by-step explanation:
g(x) = f(x) + 4.
This is because g(x) is a translation of f(x) that has been moved up by 4 units. (-2 to 2 when x = 0)
Given the graphs of y = f(x) and y = g(x),
g(x) = f(x) + 3
expresses g(x) in terms of f(x).

The list below shows the number of medals that one nation's team won at the Olympics. What is the ratio of gold medals to the total number of medals that the team won? Gold 34 Silver 30 Bronze 39
Answer:
34:103
Step-by-step explanation:
Add up all the numbers and then put gold then : then the numbers added up
A proportion exists an equation that sets two ratios at the same value.
34 : 103 exists the ratio of gold medals to the total number of medals that the team won 103.
What is the difference between ratio and proportions?When the second number in the ordered pair, b, is not equal to 0, the ratio is expressed as a/b. An equation in which two ratios are made equal is known as a percentage. A ratio is a comparison between two values. A ratio is created when two ratios are equal.
If a ratio depicts the same relationship, it is proportionate. Two ratios can be written as fractions and then reduced to determine if they are proportionate to one another. You have proportionate ratios if the reduced fractions are equal.
Use ratios to compare two things.
The formula for the ratio of any two quantities is expressed as
a : b ⇒ a/b.
On the other hand, the proportional formula is
a : b :: c : d ⟶ ab = cd
a : b :: c : d ⟶ ab = cd
Types of proportion
Direct proportionReverse proportioncompound proportionContinued proportion34 : 103 exists the ratio of gold medals to the total number of medals that the team won 34 + 30 + 39 = 103

==================================================
Explanation:
The given piecewise function basically means we have h(x) defined in two different ways based on what x is
If x is less than 2, then h(x) = 4 - x^3 which is what the first row says
Or
If x = 2 or larger, then h(x) = 2x-3 which is what the second row says.
---------
We want to find h(0). We want to find h(x) when x = 0. We'll use the first definition since x = 0 is less than 2.
h(x) = 4 - x^3
h(0) = 4 - (0)^3
h(0) = 4 - 0
h(0) = 4

Write an equation of the line passing through the point (6,-2) that is parallel to the line y=4x-11
Answer:
y=4x-26
Step-by-step explanation:
First, a parallel equation, ALWAYS has the same slope. Just plug in your x value into 4(x) , then find a number that adds or subtracts to get your y value, and that number you added or subtracted is your y-intercept.
The equation of the line passing through the point (6,-2) that is parallel to the line y=4x-11 is y = 4x - 26
The equation of the linear passes through the point (6, -2) and is parallel to the line y = 4x - 11
Parallel lines have the same slope.
Therefore,
y = 4x - 11
using
y = mx + b
where
m = slope
b= y-intercept
Therefore, the slope of y = 4x - 11 is 4.
And the slope of the other line will be 4 because they are parallel.
Therefore,
y = mx + b
y = 4x + b
it passes through (6, -2)
-2 = 6(4) + b
-2 - 24 = b
b = -26
The equation will be y = 4x - 26

How do I solve 3.24 x 1.2? I have tried and I always get the same answer! Please help! The answer is supposed to be 3.888 but I have gotten 6.47 each time. I'm good at math but I really need help!
Answer:
3.888
Step-by-step explanation:
3.24 × 1.2
Using Multiplication method multiply through like normal multiplication, don't
put your decimal yet
= 3.24
× 1.20
_______
000
6480

Counting the number of decimal places to knowing where to properly place your decimal sign
3.24 = 2 decimal place
1.20 = 2 decimal place
Total = 4 decimal places
3.8880
Therefore, 3.24 × 1.20 = 3.8880 or 3.888
Find f(-5) and f(12) for each piecewise function f(x){-4x+3 if x<3
{-x^3 If 3<_x<_8
{3x^2+1 If x>8
The lines go under the inequality lol but please help !
==================================================
Explanation:
The given piecewise function is
[tex]f(x) = \begin{cases}-4x+3 \ \text{ if } \ x < 3\\-x^3 \ \text{ if } \ 3 \le x \le 8\\3x^2+1 \ \text{ if } \ x > 8\end{cases}[/tex]
At first piecewise functions may be strange confusing things, but they aren't so bad. I like to think of it like this: f(x) is a function that changes its identity based on what the input x is. We have three situations
f(x) = -4x+3 when x < 3f(x) = -x^3 when [tex]3 \le x \le 8[/tex]f(x) = 3x^2+1 when x > 8In a sense, we have three different functions but they are combined somehow.
If x is smaller than 3, then we go for the first definition. Or if x is between 3 and 8, then we go for the second definition. Or if x is larger than 8, then we go for the third definition.
-----------------------
f(-5) means f(x) when x = -5. We see that -5 is smaller than 3, so x = -5 makes x < 3 true. We'll use the first definition
f(x) = -4x+3
f(-5) = -4(-5)+3
f(-5) = 20+3
f(-5) = 23
------------------------
Now the input is x = 12. This is larger than 8. In other words, x = 12 makes x > 8 true. We'll use the third definition
f(x) = 3x^2+1
f(12) = 3(12)^2+1
f(12) = 3(144)+1
f(12) = 432+1
f(12) = 433
------------------------
Side notes:
We won't use the second definition since we don't have any x inputs between 3 and 8To say "less than or equal to" on a keyboard, you can write "<=" without quotes. For example, [tex]x \le 5[/tex] is the same as x<=5In the figure below, Y is between X and Z

Option A is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
XZ = XY + YZ
40 = 3a + 8 + a

Answer:
x = 1/3
Step-by-step explanation:
3(x-1)-2(2x+1)=8(x-1)
Distribute
3x -3 -4x-2 = 8x -8
Combine like terms
-x -5 = 8x -8
Add x to each side
-x-5+x = 8x-8+x
-5 = 9x-8
Add 8 to each side
-5+8 = 9x-8+8
3 = 9x
Divide by 9
3/9 = 9x/8
1/3 =x
3(x-1)-2(2x+1)=8(x-1)
Use distributive property:
3x-3 -4x-2 = 8x-8
Combine like terms:
-x -5 = 8x -8
Add 8 to both sides:
-x +3 = 8x
Add x to both sides:
3 = 9x
Divide both sides by 9:
x = 3/9
x = 1/3
