Its 78/10 = 39/5
Hope it helps :)
Before you start working on this problem, make sure you know
how to use a couple of the tools in your toolbox:
Tool #1: 37-1/2 percent means 0.375
Tool #2: In math problems, "of" almost always means "times".
====================================
Your question says
"37-1/2 percent of blank is 36".
Translate it with your tools:
0.375 times blank = 36 .
Divide each side by 0.375: Blank = 36 / 0.375 .
Now grab your pencil or your calculator, and find the value of that
fraction (do the division). Blank is equal to the value of the fraction.
To check your answer (find out whether it's correct):
Do exactly what the question says.
Multiply (0.375) times (your answer). If you get 36,
then your answer is correct. If not, it's not.
-4 is Less than -3 is the answer
Step-by-step explanation: 7.2^3 or 7.2 cubed=373.248. I hope I helped.
Answer:
(y+2)= -3(x-7)
Step-by-step explanation:
We can use the slope-intercept formula to write this equation. The slope-intercept form of a linear equation is:
y
=
m
x
+
b
Where m is the slope and b is the y-intercept value.
We can substitute the slope into the formula giving:
y
=
−
3
x
+
b
Next, we can substitute the values from the points in the problem for x and y and solve for b
:

b
We can now substitute the slope from the problem and the value for b we calculated into the formula to write the equation.
y
=
−
3
x
+
19
Another process is to use the point-slope formula. The point-slope formula states:
(
y
−
y

)
=
m
(
x
−
x
1
)
Where m is the slope and (
x
1
,
y1
) is a point the line passes through.
Substituting the slope and values from the points in the problem gives:
(y

)
=
