plz help me plz and thank you god bless

Answer:

A = 38.5

Step-by-step explanation:

Answer:

Substitution is when you isolate a variable-

3) We can divide the first equation by 6 to get x+y=-1, then isolate to get y=-1-x. We plug this into the second equation to have 3x+(-1-x)=-13. We simplify and get 2x=-12 so x=-6. We plug this back into the first equation and get -6+y=-1 so y=5. So the answer as an ordered pair is (-6,5).

4) We can isolate the second equation to get x=2y+11. We substitute this into the first equation to have -7(2y+11)-2y=-13. We simplify and get -16y=64 so y=-4. We plug this back into the second equation and get x+8=11 so x=3. So the answer as an ordered pair is (3,-4).

Answer: £67.88

Step-by-step explanation:

From the estimation, we are informed that £3 = €4. This means that:

£1 = €4/3

Therefore, to convert €90.50 to pounds will then be:

= 90.50 ÷ 4/3

= 90.50 × 3/4

= 90.50 × 0.75

= 67.875

= £67.88

Step-by-step explanation:

here this might help a little Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

Step-by-step explanation:

-4 x -8 = 32 (negative and negative = positive) and the sign is greater or equal to, which the answer is equal to

Answer:

The answer is B!

Step-by-step explanation:

-4x-8=32

When you have two negatives when multiplying or dividing the answer will always be a POSITIVE.

Answer:

Look at the explanation :)

Step-by-step explanation:

Angle 2 and 3 are supplementary angles, which means they are equal.

Therefore, if

Angle 2 = 4x - 26

and

Angles 3 = 3x + 4,

It means that 4x - 26 = 3x + 4

Solve it,

4x = 3x + 30

x = 30

Input x to each angles,

Angle 2,

4(30) - 26 = 120 - 26 = 94

Angle 3,

3(30) + 4 = 90 + 4 = 94

Answer:

x=4 and y=−2

Step-by-step explanation:

y=−3x+10;y=−2x+6

Step: Solve y=−3x+10for y:

Step: Substitute−3x+10foryiny=−2x+6:

y=−2x+6

−3x+10=−2x+6

−3x+10+2x=−2x+6+2x(Add 2x to both sides)

−x+10=6

−x+10+−10=6+−10(Add -10 to both sides)

−x=−4

-x/-1 = -4/-1 (Divide both sides by -1)

x=4

Step: Substitute4forxiny=−3x+10:

y=−3x+10

y=(−3)(4)+10

y=−2(Simplify both sides of the equation)

Answer:

Solution is the point (4, -2)

Step-by-step explanation:

use the expression for y from the first equation in the second equation:

then the equation y = - 2 x + 6 becomes:

- 3 x + 10 = - 2 x + 6

add 3 x to both sides

10 = 3 x - 2 x + 6

10 = x + 6

subtract 6 from both sides

x = 4

Now replace x with 4 in the first equation to find y:

y = - 3 x + 10 = - 3 (4) + 10 = - 12 + 10 = -2

Therefore this is the point solution to the system:

(4, -2)

Answer:

11x

Step-by-step explanation:

Start by simplifying the parentheses. (8.1+7.9)=16 and (25/5)=5. Next, distribute each x into the parentheses. You should now have 16x-5x. Since they share like terms, you can subtract them.

Answer:

x = 5/2 + sqrt(61)/2 or x = 5/2 - sqrt(61)/2

Step-by-step explanation:

Solve for x over the real numbers:

x^2 - 5 x - 6 = 3

Hint: | Solve the quadratic equation by completing the square.

Add 6 to both sides:

x^2 - 5 x = 9

Hint: | Take one half of the coefficient of x and square it, then add it to both sides.

Add 25/4 to both sides:

x^2 - 5 x + 25/4 = 61/4

Hint: | Factor the left hand side.

Write the left hand side as a square:

(x - 5/2)^2 = 61/4

Hint: | Eliminate the exponent on the left hand side.

Take the square root of both sides:

x - 5/2 = sqrt(61)/2 or x - 5/2 = -sqrt(61)/2

Hint: | Look at the first equation: Solve for x.

Add 5/2 to both sides:

x = 5/2 + sqrt(61)/2 or x - 5/2 = -sqrt(61)/2

Hint: | Look at the second equation: Solve for x.

Add 5/2 to both sides:

Answer: x = 5/2 + sqrt(61)/2 or x = 5/2 - sqrt(61)/2

Answer:

  19.25 miles

Step-by-step explanation:

Antoine's rate before lunch was ...

  (5.25 mi)/(3 h) = 1.75 mi/h

Then his rate after lunch was ...

  2×(1.75 mi/h) = 3.5 mi/h

The distance he hiked after lunch was ...

  distance = speed × time

  (4 h)×(3.5 mi/h) = 14 mi

The distance Antoine hiked is the total of his before-lunch distance and his after-lunch distance:

  5.25 mi + 14 mi = 19.25 mi

Answer:

$ 37.50

Step-by-step explanation:

We can rewrite this problem as: What is 6% of $625?

"Percent" or "%" means "out of 100" or "per 100",

Therefore 6% can be written as 6/100.

When dealing with percents the word "of" means "times" or "to multiply".

Finally, lets call the sales tax we are looking for "t".

Putting this altogether we can write this equation and solve for t while keeping the equation balanced:

t=6100×$625

t=$3750100

t=$37.50

Answer:

40.50

Step-by-step explanation:

Sales price x sales tax rate = sales tax

675 x .06 (6%) = 40.50
