Answer:
\(\textsf{C)}\quad 3x-45=10\)
Step-by-step explanation:
Given equation:
\(\dfrac15x-3=\dfrac23\)
Multiply both sides by 3:
\(\implies 3\left(\dfrac15x-3\right)=\dfrac23 \cdot 3\)
\(\implies \dfrac{3 \cdot 1}{5}x-3 \cdot 3=\dfrac{2 \cdot 3}{3}\)
\(\implies \dfrac35x-9=2\)
Multiply both sides by 5:
\(\implies 5\left(\dfrac35x-9\right)=2 \cdot 5\)
\(\implies \dfrac{5 \cdot 3}{5}x-5 \cdot 9=10\)
\(\implies 3x-45=10\)
Explanation
1/5x-3=2/3
Multiply both sides
3x-45=10

Answers
Answer:
11
Step-by-step explanation:
We can write a simple equation to better help understand
((M / 4) - 2) + 10
Now we plug in the value 12
((12/4) - 2) + 10 = (3 - 2) + 10 = 1 + 10
= 11
Therefore, our answer is 11.
Answer:
\(11\)
Step-by-step explanation:
Equation: \((\frac{x}{4} -2) +10\)
= \((\frac{12}{4} -2) +10\)
= \((3-2)+10\)
= \(1+10\)
= \(11\)

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Answers
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)
