Answer:
Step-by-step explanation:
9 = - 7w + 12w - 6
by transposing,
9 + 6 = -7w + 12w
15 = 5w
w = 15 / 5
w = 3
Hope this helps
plz mark as brainliest!!!!!!
Answer:
[tex]w=3[/tex]
Step-by-step explanation:
[tex]9 = -7w + 12w -6[/tex]
Start by combining like terms ([tex]-7w+12w[/tex]):
[tex]9=5w-6[/tex]
Add [tex]6[/tex] to both sides of the equation:
[tex]15=5w[/tex]
Divide both sides of the equation by the coefficient of [tex]w[/tex], which is [tex]5[/tex]:
[tex]3=w[/tex]
_
Check your work by substituting the solved value of [tex]w[/tex] ([tex]3[/tex]), into the initial equation:
[tex]9 = -7(3) + 12(3) -6[/tex]
Multiply:
[tex]9=-21+36-6[/tex]
Combine like terms:
[tex]9=9[/tex]
Since both sides of the equation are equal, our answer is correct!
A number b divided by -3 is greater than or
equal to 6.
Answer:
[tex]b/3\geq 6[/tex]
Step-by-step explanation:
Answer:
b[tex]\geq[/tex]-18
Step-by-step explanation:
[tex]\frac{b}{-3}[/tex] [tex]\geq[/tex] 6 Solve this just like there is an equal sign instead of [tex]\geq[/tex]
Multiply both sides by -3 to get b by itself: b[tex]\geq[/tex]-18

Find f'(x) if f(x)=3x- 12
Answer:
4
Step-by-step explanation:
f(x) = 12 and f(x) = 3x
12/3 = 4 and the function for f(x) is 3(4)
The derivative of the function f(x) = 3x - 12 is 3.
What is a derivative ?Derivative of a function measures the rate of change of a function it can also be defined as the slope of the function.If given dy/dx it states the rate of change of y with respect to x.
According to the given question we have find the first derivative of the function f(x) = 3x - 12.
Given f(x) = 3x - 12
f'(x) = 1(3)x¹⁻¹ + 0 ( derivative of any constant is 0 )
f'(x) = 3x⁰.
f'(x) = 3.

PERIMETER IS ADDING ALL SIDES, AREA IS MULTIPLYING TWO SIDES
1. 2 1/9
2. 42.25
3. 4
4. 87
Answer:
perimeter is adding up all the outside line measures, so for the squares with only one side value, just multiply that by four
the other ones, for the measure given for one side, the opposite side is the same measure, so just add that up.
so number one would be 9 and 1/3 (nine and one third)

Bob rented a truck for one day. There was a base fee of $18.99, and there was an additional charge of 75 cents for each mile driven. Bob had to pay $159.24
when he returned the truck. For how many miles did he drive the truck?
Answer:
1.87 miles
Step-by-step explanation:
[let's say x = how many miles]
18.99 + 75x = 159.24 [write out the equation]
-18.99 -18.99 [subtraction property of equality]
75x = 140.25

Find the x and y intercept of the following equation 4x-10y=20
For the given linear equation we have:
y-intercept: y = -2x-intercept: x = 5.How to find the intercepts for the linear equation?Here we have a linear equation:
4x -10y = 20
First, let's find the y-intercept, this is the point with x = 0, so evaluating in that we get:
4*0 - 10y = 20
-10y = 20
y = 20/-10
y = -2
The x-intercept is what we get by evaluating in y = 0.
4x - 10*0 = 20
x = 20/4
x = 5

A boat travels upstream on the Mississippi river for 3.5 hours. The return trip only takes 2.5 hours because the boat travels 2 miles per hour faster downstream due to the current. How far does the boat travel upstream? Which is the best equation to use?
Answer:
17.5 miles per hour
Step-by-step explanation:
A boat travels upstream on a Mississippi river for 3.5 hours
The return trip takes 2.5 hours
The boat travels 2 miles per hour faster downstream
Let y represent the speed that was travelled upsteam
3.5y = 2.5(y + 2)
3.5y = 2.5y + 5
3.5y - 2.5y = 5
y = 5
Therefore the distance travelled by the boat upstream can be calculated as follows
= 3.5 × 5
= 17.5 miles per hour

Which values of a, b, and c correctly complete the division? One-fourth divided by StartFraction 5 Over 6 EndFraction = StartFraction 1 Over a EndFraction times StartFraction b Over c EndFraction a = 4, b = 5, c = 6 a = 1, b = 6, c = 5 a = 1, b = 5, c = 6 a = 4, b = 6, c = 5
Answer:
a = 4, b = 6 and c = 5
Step-by-step explanation:
It is given that,
[tex]\dfrac{\dfrac{1}{4}}{\dfrac{5}{6}}=\dfrac{1}{a}\times \dfrac{b}{c}[/tex]
We know that,
[tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]
So,
[tex]\dfrac{1}{4}\times \dfrac{6}{5}=\dfrac{1}{a}\times \dfrac{b}{c}[/tex]
If we compare both sides of the equation we get,
a = 4, b = 6 and c = 5
Hence, these are the values of a,b and c.
