1.2x+4.3=2.1-x
Please help!!!
Answer:
x=1
Step-by-step explanation:
subract 4.3 from both sides. add x to both sides. divide by 2.2 from both sides
The solution to the equation 1.2x + 4.3 = 2.1 - x is x = -1.
Given is an equation 1.2x + 4.3 = 2.1 - x, we need to solve for x,
To solve the equation 1.2x + 4.3 = 2.1 - x, we can follow these steps:
1. Combine like terms on both sides of the equation:
1.2x + x = 2.1 - 4.3
2. Simplify the equation:
2.2x = -2.2
3. Divide both sides of the equation by 2.2 to isolate x:
x = -2.2 / 2.2
4. Simplify the right side of the equation:
x = -1
Therefore, the solution to the equation 1.2x + 4.3 = 2.1 - x is x = -1.

Which function represents the same relationship?
Answer:
y=-3x-10.5
Step-by-step explanation:
Let's use the first set of numbers.
-7.5 and 12
-3.5 and 0
Our rise here is -12 and run is 4. So, our slope is -3.
Now we just need our intercept.
y = mx + b
y = -3x + b
0 = -3(3.5) + b
b = -10.5
The function represents the same relationship between x and y will be x + 3y + 3.5 = 0.

Take two points from the table, then the points are (-7.5, 12) and (-3.5, 0). Then the equation of the line is given as,
y - 0 = [(-3.5 + 7.5) / (0 - 12)](x + 3.5)
y = - (1/3)(x + 3.5)
3y = - x - 3.5
x + 3y + 3.5 = 0
The function represents the same relationship between x and y will be x + 3y + 3.5 = 0.

Solve for x if 5x + 2(x - 3) = 7x - 6
Help me plsss
Answer:
x = 3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5x + 29 (x − 3) = 7x − 6
5x + (29) (x) + (29) (−3) = 7x + −6 (Distribute)
5x + 29x + −87 = 7x + −6
(5x + 29x) + (−87) = 7x − 6 (Combine Like Terms)
34x + −87 = 7x − 6
34x − 87 = 7x − 6
Step 2: Subtract 7x from both sides.
34x − 87 −7x = 7x −6 −7x
27x − 87 = −6
Step 3: Add 87 to both sides.
27x − 87 + 87 = −6 + 87
27x = 81
Step 4: Divide both sides by 27.
27x/27 = 81/27
x = 3

Answer :
Width : 9
length: 3.6
The perimeter will be 25.2
-----------------------------------------------------------------------------------------------------------------
Show your work : Since the length and width are 3 times bigger have to multiply the old one by 3
so 1.2 times 3 = 3.6
so 3 times 3 = 9
thats the length
to find the perimeter its 2L + 2W
2(3.6) + 2(9)=25.2

Sorry if the other answer misleads you. Here is the real answer!
The answer to the expression m +(3n - 5)² is 55.
What is Expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.Given:
m +(3n - 5)²
Now, put the value of m= 6 and n= 4 we get
m +(3n - 5)²
= 6 +(3(4) - 5)²
= 6 +(12 - 5)²
= 6 +(7)²
= 6+ 49
= 55
Hence, the answer is 55.

The basketball gym at Dustin's school was built in the 1940s and needs a lot of repairs. So, the school is asking families for donations to build a new gym. Dustin convinced some local businesses to match a fraction of the families' donations. There is a proportional relationship between the amount of money a family donates (in dollars), x, and the matching contribution (in dollars) from local businesses, y. When a family donates $12, the businesses contribute $9. Write the equation for the relationship between x and y.
Answer:
The equation representing the relationship between x and y is that;
4y = 3x
Step-by-step explanation:
Here, we want to write a relationship.
From the question, we are told that the amount donated by the family which is x dollars is proportional to what local businesses gave.
From the question, there was an example in which a family gave $12 and local businesses gave $9
So let us establish a relationship using ratio of x to y
Thus;
12/9 = x/y
12y = 9x
4y = 3x

Huang Yi works as a paleontologist and a sculptor. She earns \$5{,}500$5,500dollar sign, 5, comma, 500 per month as a paleontologist and \$4{,}500$4,500dollar sign, 4, comma, 500 per month as a sculptor. Huang Yi wants to make more than \$50{,}000$50,000dollar sign, 50, comma, 000 this year. In the inequality shown above, PPP represents the number of months Huang Yi can work as a paleontologist and SSS represents the number of months she can work as a sculptor to reach her goal. If Huang Yi worked for 666 months as a paleontologist this year, what is the minimum whole number of months that she must work as a sculptor to reach her goal?
Answer:
4 months
Step-by-step explanation:
Let P represents the number of months Huang Yi can work as a paleontologist and S represents the number of months she can work as a sculptor to reach her goal.
If she works for P months as an paleontologist, her income would be 5500P while if she works for S months as a sculptor her income would be 4500S.
Her total income = 5500P + 4500S
Since she wants to earn more than $50000, hence:
5500P + 4500S > 50000
Given she worked as a paleontologist for 6 months, therefore:
5500(6) + 4500S > 50000
33000 + 4500S > 50000
4500S > 50000 - 33000
4500S > 17000
S > 17000/4500
S > 3.78
S > 4
The minimum whole number of months that she must work as a sculptor to reach her goal is 4 months
