Solving systems of equations using substitution/elimination

Step-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 = -2

Step 4: Solve for x

Define original equation: x - 7y = 7Substitute in y: x - 7(-2) = 7Multiply: x + 14 = 7Isolate x: x = -7

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

14x +1

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

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?

Answers

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.

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?

Answers

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.

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.

Answers

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
