Step-by-step explanation:
You are correct in saying false
well, the cheap answer is, linear expressions have one variable and some coefficient in front of it, like 3x or 2y + 3, or (1/4)x - 15 or such, however, a LINEar expression when drawn, yields a LINE, not a curve or such, and that only happens if the variable's exponent is 1, not more than 1, if the variable's exponent is higher, then is a curve of kinds,
so such expressions like -13xy, which has the product of two variables, or 7y³ - 2 or 4x⁵ + 9, are curvy lines.

Let's break this problem down in a few steps
x over 6 ⇒ x divided by 6 ⇒ [tex]\frac{x}{6}[/tex]10 over 12 ⇒ 10 divided by 12 = [tex]\frac{10}{12}=\frac{2*5}{2*6} =\frac{5}{6}[/tex]Since these two fractions are equal to each other, let's solve for x
[tex]\frac{x}{6}=\frac{5}{6} \\6x=30\\x = 5[/tex]
Thus x = 5
Hope that helps!
Answer:
[tex]x = 5[/tex]
Step-by-step explanation:
Step 1: Convert to an expression
x over 6 equals 10 over 12
[tex]\frac{x}{6}=\frac{10}{12}[/tex]
Step 2: Cross multiply
[tex](x * 12) = (6 * 10)[/tex]
[tex]12x = 60[/tex]
Step 3: Divide both sides by 12
[tex]\frac{12x}{12} = \frac{60}{12}[/tex]

When you use a graphing calculator to construct a 95% confidence interval for μMajor – μMinor = the true difference in the mean healing time will be 1.406, 5.369.
What is a Graphing Calculator?A graphing calculator is known to be a kind of handheld computing device that is used for plotting of graphs, handling simultaneous equations, etc.
Note that by inputting those numbers such as Major: 8, 9.5, 10, 12, 11.5 Minor: 6, 7, 5.5, 8, 9, 6, 7, 6 , following the right equation on the graphing calculator, one can be able to construct a 95% confidence interval for μMajor – μMinor = and the the true difference in the mean healing time will be found to be 1.406, 5.369.

Three metallic tanks have the capacities of 447 litres, 577 litresand 669 litres. Find the capacity of the largest container that can fill the tanks an exact number of times, leaving a remainder of 7 litres, 5 litres and 9 litres respectively. (3 marks)
Answers
Answer:
44 litres
Step-by-step explanation:
We subtract the remainders from the amounts.
447 - 7 = 440
577 - 5 = 572
669 - 9 = 660
Now we need the GCF of 440, 572, 660
440 = 2³ × 5 × 11
572 = 2² × 11 × 13
660 = 2² × 3 × 5 × 11
GCF = 2² × 11 = 44
The greatest common factor is 44.
Answer: 44
Check:
447/44 = 10 reminder 7
577/44 = 13 remainder 5
669/44 = 15 remainder 9
In degrees what is the measure of MFE
Answers
There's a lot going on in this problem, but I think I know how to solve it. So let's first address the fact that opposite angles are equal.
Let's also address the fact that (x + 6) + (3x - 4) add up to equal 90. So with that information, we can write a problem.
x + 6 + 3x - 4 = 90
Add the x's.
4x + 6 - 4 = 90
Combine the 6 and 4.
4x + 2 = 90
Subtract the two on both sides.
4x = 88
Finally, divide by 4.
x = 22
But by no means are we done yet. We still have to find out the entire angle MFE's measure, so we'll substitute 22, our new x value, into the equation for MFE - (x + 6)
22 + 6 is the new equation.
22 + 6 = 28
Angle MFE is 28°. I took the liberty of solving for the other angle, too, so I could check the answer. And as of my checking, this answer is correct because
62 + 28 = 90
I hope this answers your question.

What is the experimental probability of rolling a number less than 4?

B: 16/33
C: 1/22 D: 17/33
what is the answer?
HELP
Answers
Answer:
A. 1/2
Step-by-step explanation:
For the question, it says what is the experimental probability of rolling a number less than 4, meaning it is asking for the experimental probability of rolling a 1, 2, or 3. Assuming this is a fair 6-sided dice, the probability of rolling any number is 1/6. The probability of rolling a 1, 2, or 3 is also 1/6. Adding all those the probabilities of 1, 2, and 3 together gets 3/6, which simplifies to 1/2.
Therefore, the experimental probability of rolling a number less than 4 is 1/2.
= 0.5 which is 50% half so A:1/2 is the answer

3 x 2/3 + 1/5 x 2/332/152 2/15.What is Fraction?Every fraction has a numerator and a denominator separated by a horizontal bar known as the fractional bar.
The denominator represents the number of components into which the whole has been subdivided. It is positioned below the fractional bar in the lower section of the fraction.The numerator specifies how many fractional parts are depicted or selected. It is positioned above the fractional bar in the upper section of the fraction.As, the length of the painted area is 3 1/5 and width of the painted area is 2/3.
So, multiplication of length and width is as follows:
3 1/5 x 2/3
= 3 x 2/3 + 1/5 x 2/3
= 6/3 + 2 / 15
= 30 + 2 / 15
= 32/ 15
= 2 2/15
Thus, the required fraction is 2 2/15.
