5x-4=11
Can anyone answer this for me
Answer:
3
Step-by-step explanation:
5x=11+4
5x=15
x=15/5
x=3
Answer:
x=3 is the answer.
Solve:
3(4 - 2x) = -x +1
13
X =
5
O B. x = 11
O C. x= -1
x-5
D. X
Step-by-step explanation:
[tex]3(4 - 2x) = - x + 1 \\ 12 - 6x = - x + 1 \\ 12 - 1 =6x - x \\ 11 = 5x \\ \frac{11}{5} = x \\ 2 \frac{1}{5} = x \\ [/tex]
The solution of the equation is x = 11/5
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
The given equation is,
3 (4 - 2x) = -x + 1
We have to solve the equation.
Distributive property states that, for three numbers, a, b and c,
a(b + c) = ab + ac
So, 3 (4 - 2x) = (3 × 4) - (3 × 2x)
= 12 - 6x
Substituting,
3 (4 - 2x) = -x + 1
12 - 6x = -x + 1
-6x + x = 1 - 12
-5x = -11
x = 11/5
Hence the solution is x = 11/5.

| x/3 | = 3 Absolute Value Equations if someone could please explain to me how to do this it would be much appreciated.
Answer:
Absolute value equations are equations where the variable is within an absolute value operator, like |x-5|=9. The challenge is that the absolute value of a number depends on the number's sign: if it's positive, it's equal to the number: |9|=9. ... So when we're dealing with a variable, we need to consider both cases.

Hey there!
To find the answer to a fraction to convert it to a decimal you have to DIVIDE to NUMERATOR (the TOP number) from the DENOMINATOR (the BOTTOM number) and it should give you your result to this given question
Option A doesn’t have anything to do with 8/9 because the question isn’t asking what is equivalent to eight divided one-ninths.
Option B. could possibly be your answer because it is asking what is equivalent to 8/9
Option C. also doesn’t have anything to do with 8/9 because the question isn’t asking what it is equivalent to nine divided one-eighths. 9 1/8 =
Option D. as well doesn’t have to do with 8/9 because the equation isn’t 9/8 so you can’t divided 9 from 8
Based on the information we have now. We can answer the question.
Possible answer: Option B. 8 ÷ 9

If Tristan wants to stretch the spring by 9 inches, how many kilograms of weight must he apply to it?
Answer:
Step-by-step explanation:
Substitute y = 9 into the equation y = 3x, or locate the answer on the graph:
y = 3x
9 = 3x.
Divide both sides of the equation by 3:
[tex]\frac{9}{3}[/tex] = [tex]\frac{3x}{3}[/tex]
3 = x
The spring stretches 9 inches with 3 kilograms of weight attached to it.

Answer:
25 and 55
Step-by-step explanation:
Let's call the larger number L and the smaller S
L = 5 + 2×S
And the sum is:
L + S = 80 Subtract S in both sides:
L = 80 - S
Now, substitute this value of L in the first equation:
80 - S = 5 + 2×S Add S in both sides:
80 = 5 + 2×S + S
80 = 5 + 3S Subtract 5 in both sides
75 = 3S Divide both sides by 3
25 = S
We find the value of S, and now we substitute it in the second equation to find the value of L:
L = 80 - 25
L = 55
