What is the value of c?
14 = - 2c - 6 - 3c
Answers
Answer:
c = -4
Step-by-step explanation:
Step 1: Write equation
14 = -2c - 6 - 3c
Step 2: Solve for c
Combine like terms: 14 = -5c - 6Add 6 on both sides: 20 = -5cDivide both sides by -5: c = -4Step 3: Check
Plug in c to verify it's a solution.
14 = -2(-4) - 6 - 3(-4)
14 = 8 - 6 + 12
14 = 2 + 12
14 = 14
14=-6-5c
Get 6 on the other side by adding 6 to itself and what you do to one side you do to the other.
20=-5c
Now divid each side by -5
C= -4

Lindsay buys 15 3/4 gallons of gasoline for $3.50 per gallon how much the whole tank cost
Answers
Answer:
The whole tank cost $55.13
Step-by-step explanation:
All you have to do is multiply the fraction and cost, to ge thte total cost
15 3/4 also equals 15.75 (it will be easier to multiply two fractions)
now each gall of the 15.75 costs 3.50 so we multiply the number of gallons by the cost
15.75 x 3.50 = 55.125
but now we must round since there isnt .125 cents
so
55.13 is the cost

Could anyone help me with this problem, Quickly Please...
Answers
Answer:
3/4
Step-by-step explanation:
Since (p, r) lies on the line y = x + b,
we have,
r = p + b -----eq(1)
Since (2p, 5r) lies on the line y = 2x + b,
we have,
5r = 2(2p) + b -----eq(2)
Sub the value of r from eq(1) in eq(2),
5(p + b) = 4p + b
⇒ 5p + 5b = 4p + b
⇒ 5b - b = 4p - 5p
⇒ 4b = -p
⇒ b = -p/4
sub in eq(1)
r = p + (-p/4)
= p - p/4
= 3p/4
⇒ r = 3p/4
⇒ r/p = 3/4
Answer:
3/4
Step-by-step explanation:
We have two lines:
r = p + b eq(1)
5r = 4p + b eq(2)
eq(2) - eq(1)
4r = 3p
dividing by 4p
r/p = 3/4

Step-by-step explanation:Since angles 1 and 2 are supplementary, it follows that there sum is 180°.
On this note;
Sum of 1 and 2 is;
180 = 124 + (2x + 4)°
(2x + 4)° = 180 -124

Joseph drove to his grandmothers house which is 279 miles away in 4.5 hours.If he continues at the same speed, approximately how long will it take him to drive 325 miles?
Answers
Answer: 5.24
Step-by-step explanation:
I like to set these up as ratios.
279 miles/4.5 hours = 325 miles/ x hours
Then cross multiply
279x = 4.5 x 325
279x = 1462.5
divide both sides by 279
x = 5.24 hours
You can also solve 279 miles/4.5 hours to get the miles per hour driven, then divide 325 by that number:
279/4.5 = 62mph
325/62 = 5.24
Answer:
5•24hours
Step-by-step explanation:
I like to set these up as ratios
279miles/4•5hours=325miles/×hours
then cross multiply
279×=4•5×325
279×1462•5
divide both sides by 279
×=5•24hours
you can also solve 279miles/4•5hours to get the miles per hour driven،then divide 325 by that number:
279/4•5=62mph
325/62=5•24

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
\(a=-15b-5\)
