Solve by substitution x-7y=7 6x-7y=-28
Answer:
(-7, -2)
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
x - 7y = 7
6x - 7y = -28
Step 2: Rewrite systems
x = 7y + 7
6x - 7y = -28
Step 3: Solve for y
Substitute: 6(7y + 7) - 7y = -28Distribute 6: 42y + 42 - 7y = -28Combine like terms: 35y + 42 = -28Isolate y term: 35y = -70Isolate y: y = -2Step 4: Solve for x
Define original equation: x - 7y = 7Substitute in y: x - 7(-2) = 7Multiply: x + 14 = 7Isolate x: x = -7And we have our answer!
Twelve large bottles of water cost $9.How many bottles can you buy for $3?
Answer: 4 large bottles of water for $3.
Step-by-step explanation: To find how many large water bottles you can buy with $3, you’ll have to divide 12 by 3 which equals to 4. You can check your answer by multiplying 4 x 3 which equals to 12, which is the original amount of large water bottles you can buy for $9.

GAVE ME THE BRAINLIEST IF MY ANSWER WAS HELPFUL...
Answer:
b. 31.25
Step-by-step explanation:
[tex]\frac{10}{y} :\frac{32}{100}[/tex]
y × 32 = 10 × 100
32y = 1000
32y ÷ 32 = 1000 ÷ 32
y = 31.25
1) The value of y varies directly with x. If x = 3, then y = 13.
Show your work for finding the value of x when y = 39?
Answer:
When y is 39 x is 3.
Step-by-step explanation:
Proportions!
x = 3
y = 13
We need to find our multiplier first. How did 13 turn into 39?
39/13 = 3
13 * 3 = 39
We multiplied by 3!
Now we multiply x by three to keep the propotion, proportional!
x= 3
(3) * 3 = 9
Now we make the proportion
3 : 39
When y is 39 x is 3.

Darnell's car used 8 gallons of gasoline to travel 340 miles. After a mechanic worked on the car, it used 7 gallons of gasoline to travel 350 miles. How many more miles per gallon did Darnell's car travel after the mechanic worked on it?
Answer:
7.5 miles per gallon
Step-by-step explanation:
Given that:
8 gallons of gasoline traveled 340 miles
After being worked on by the mechanic :
7 gallons travels 350 miles
How many more miles per gallon did Darnell's car travel after the mechanic worked on it?
Obtain the unit mile traveled per gallon before and after the mechanic worked on the car :
Miles per gallon before being worked on by mechanic :
340 miles / 8 gallons = 42.5 miles per gallon
Miles per gallon after being worked on by mechanic :
350 miles / 7 gallons = 50 miles per gallon
(50 - 42.5) = 7.5 miles per gallon
Hence, vehicle moved 7.5 more miles per gallon after bwing worked on by mechanic.
A rectangular field is to be enclosed by a fence and divided
into two parts by another fence. Find the maximum area
that can be enclosed and separated in this way with 800 m
of fencing
Answer:
80000 square meters
Step-by-step explanation:
perimeter + dividing fence = 800
let a = length
let b = width
let c = length of dividing fence
perimeter = 2*a + 2*b
let's say...
c is the same as the length
2a + 2b + c = 800
2a + 2b + a = 800
3a + 2b = 800
area = length*width
area = a*b
area / b = a
3*(area/b) + 2b = 800
3*(area/b) = 800 - 2b
area/b = (800 - 2b)
area = (800 - 2b)*b
To make the area large, we make the right hand side large.
800b - 2b^2
If you put in terms of x, y it looks like a downward opening parabola, so the max area is at the vertex. Half way between the roots.
y = -2x^2 + 800x
y = -x^2 + 400x
0 = x*(-x + 400)
roots are x= 0 and x = 400
vertex is at x, aka b = 200
area at b=200 is (800 - 400)*200 = 80000
and a is area/b... 80000/400 = 200
The state of Colorado covers about 1.04 x 10^5 square miles. The Indian Ocean covers about 2.808 x 10^7 square miles. How many times bigger is the Indian Ocean than Colorado?
Answer:
27976000
Step-by-step explanation:
1.04 x 10^5=104000, and 2.808 x 10^7=28080000

m=2/3; passes through the point (3,-1)
your response will be the number value for b
9514 1404 393
Answer:
-3
Step-by-step explanation:
The "b" is the y-intercept in the slope-intercept form ...
y = mx + b
Filling in the given values, we can find b.
-1 = (2/3)(3) +b
-1 = 2 + b . . . . simplify
-3 = b . . . . . . . subtract 2
The value for b is -3.

Help. I might be dumb for not knowing this but please help
Answer:
1
Step-by-step explanation:
Answer:
14 x + 1
Step-by-step explanation:
You aren't dumb, your teacher can't teach!
First we must add the x values together:
8x - 7 + 6x + 8
8 + 6 = 14
14x -7 + 8
Now we add the constants (regular numbers):
14x -7 + 8
-7 + 8
14x +1
There we go!
8x -7 + 6x +8
is
14x +1
Philip's rectangular deck is 5 yards wide. The ratio of the width to the length is 4 to 5. What is the approximate length of Philip's deck in feet? Hint: 1 yard = 3 feet.
Answer:
18.75 feet
Step-by-step explanation:
Step 1
we find the length of Philip's rectangular deck in yards
The ratio of the width to the length is 4 to 5.
Philip's rectangular deck is 5 yards wide.
Hence,
Hence:
4/5 = 5/x
Cross Multiply
4x = 5 × 5
4x = 25
x = 25/4
x = 6.25 yards
The length of Philip's field = 6.25 yards
Hint: 1 yard = 3 feet.
Converting the yard to feet
1 yard = 3 feet
6.25 yards = x
Cross Multiply
x = 6.25 × 3 feet
x = 18.75 feet
Therefore, the length of Philip's field in feet = 18.75 feet
