if a/3=b/2 what are the following ratios? 3a-3b/a-b
Answer:
[tex]\dfrac{3a-3b}{a-b}=\dfrac{3}{1}[/tex]
Step-by-step explanation:
[tex]\text{Given}\\\\\dfrac{a}{3}=\dfrac{b}{2}\qquad|\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup\cdot\dfrac{a}{3\!\!\!\!\diagup}=3\cdot\dfrac{b}{2}\\\\a=\dfrac{3b}{2}[/tex]
[tex]\text{Substitute to}\ \dfrac{3a-3b}{a-b}:\\\\\dfrac{3\cdot\frac{3b}{2}-3b}{\frac{3b}{2}-b}=\left(\dfrac{9b}{2}-3b\right):\left(\dfrac{3b}{2}-\dfrac{2b}{2}\right)=\left(\dfrac{9b}{2}-\dfrac{6b}{2}\right):\left(\dfrac{3b-2b}{2}\right)\\\\=\left(\dfrac{9b-6b}{2}\right):\dfrac{b}{2}=\dfrac{3b\!\!\!\!\diagup}{2\!\!\!\!\diagup}\cdot\dfrac{2\!\!\!\!\diagup}{b\!\!\!\!\diagup}=\dfrac{3}{1}[/tex]
Other method:
[tex]\dfrac{3a-3b}{a-b}=\dfrac{3(a-b)}{a-b}\qquad|\text{cancel}\ (a-b)\\\\=\dfrac{3}{1}[/tex]

HELP! Please
Answer:
a. 68
Step-by-step explanation:
You just have to subtract these two numbers from 180 because adding all the angles of a triangle the resulta is 180. Subtracting those numbers from 180 will give you the result.
Janet wants to build a fence around her square garden.her garden has an area of 81 square feet.How much fencing will Janet need?
Area of garden = 81 ft²
Area of square = side²
[tex] \rm \implies side ^{2} = 81 \\ \\ \rm \implies side = \sqrt{81} \\ \\ \rm \implies side = \sqrt{ {9}^{2} } \\ \\ \rm \implies side = 9 \: ft[/tex]
Perimeter of square = 4 × Side
= 4 × 9
= 36 ft
[tex] \therefore [/tex] Fencing needed by Janet = 36 ft
Is 7,8,10 linear or non linear and why and pls don’t use big words cuz I don’t and then the teacher gonna ask why hahahah
Answer:
9 and 8 are linear and 10 is non linear
Step-by-step explanation:
an = dn - c
The an stands for the nth term of the pattern. So a1 is the first term and a2 is the second term of the pattern. The d is the difference between each of the terms. The n stands for the term you're calculating. If you're calculating the third term, then n is 3. And c is a constant that you'll need to calculate.
For example, the linear number pattern of 1, 3, 5, 7, 9, … has an equation of:
an = 2n - 1.
Given a
6 and a common
difference of – 12, find the
18th term in the sequence.
Answer:-210
Step-by-step explanation:6, -6, -18, so, you multiply -12 by 18, and you can find that number. -12 times 18=-216, and -216+the first number 6, equals 210
What is the mZACB?
O 10°
B
O 50°
(4x)
O 90°
O 180°
(7x-20)
C
Answer:
50 degrees
Step-by-step explanation:
The total sum of angles in a triangle is 180, thus the value of ∠ACB will be obtained as follows:
Given that the triangle is a right triangle, the sum of angles will be:
(4x)°+(7x-20)°+90=180
simplifying and solving for x we get:
4x+7x-20+90=180
11x=180+20-90
11x=110
dividing both sides by 11 we get:
(11x)/11=110/11
this gives us
x=10°
Thus substituting the value of x in:
∠ACB=(7x-20)°
=(7*10-20)
=70-20
=50°
Answer: 50°
Describe the slope of the line.
The slope of line from the given graph is 4/3.
The coordinates of line from the given graph are (4, 3) and (1, -1).
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
Now, put (x1, y1) = (4, 3) and (x2, y2) = (1, -1) is slope formula, we get
Slope = (y2-y1)(x2-x1)
= (-1-3)/(1-4)
= 4/3
Therefore, the slope of line from the given graph is 4/3.

while holding her cat, Mya steps on a scale, the scale reads 127 pounds. Alone, Mya weighs 112 pounds. Write an addition equation to find the weight of Mya's cat.
Answer:
127+(-112)=15
Step-by-step explanation:
If you subtract 112 from 127, you can find the difference. Since 112 is Mya's weight, and the total is 127, we need to find out how much weight is left over after we take away Mya's weight, which would be the cat's weight. So if you follow the expression, which is 127+(-112), you would get a sum of 15 pounds. Since this is an addition problem, the expression would be 127+(-112) instead of 127-112. I hope you understand. The difference between 127 and 112 is the cat's weight, so the cat weighs 15 pounds.
Find the slope of the line y=1/6x+3/2
The slope of the given line is [tex]\frac{1}{6}[/tex].
The slope of a line is the ratio of the amount that y increases as x increases some amount. Slope tells you how steep a line is, or how much y increases as x increases.
When a linear equation is written in slope intercept form, the slope of the line can easily be identified. The slope is "m" or the coefficient of x in the equation.
According to the question ;
The given line is
[tex]y = \frac{1}{6} x + \frac{3}{2}[/tex]
By comparing with the standard equation of the line .
y = mx + c
[tex]m = \frac{1}{6} \\ c = 6 \\[/tex]
Now ; slope of the line = m = [tex]\frac{1}{6}[/tex]
The slope of the line is [tex]\frac{1}{6}[/tex] .

What is the equation of the line that passes through the point (1, 7) and has a slope of 2/7?
Answer: y=2/7x+47/7
Step-by-step explanation:
You would use the equation y=mx+b to get the answer. You already know that x=1 and y=7 from the given point and they tell you the slope (m) is 2/7. All you have to do it substitute the values into the equation and solve for b. That would be 7=(2/7)(1)+b. Solving for b gives you 47/7. Therefore, the equation is y=2/7x+47/7. Hope this helps!
