Answer:

A= 48°

B= 60°

C= 72°

D= 20°

E= 20°

F= 160°

G= 160°

Step-by-step explanation:

A= 180° -90° -42° (∠ sum of △)

A= 48°

D= 180° -42° -28° -90° (∠ sum of △)

D= 20°

E= D (vert. opp. ∠s)

E= 20°

G= 180° -D (adj. ∠s on a str. line)

G= 180° -20°

G= 160°

F= G (vert. opp. ∠s)

F= 160°

C= 180° -88° -D (∠ sum of △)

C= 180° -88° -20°

C= 72°

A +B +C= 180° (adj. ∠s on a str. line)

48° +B +72°= 180°

B +120°= 180°

B= 180° -120°

B= 60°

Answer:

John had $2088 originally in his savings accounts.

Step-by-step explanation:

Let John had $x originally in his saving account

He spent $198 on a radio. The remaining money = x - $198

4/12 of what was left, he spent on presents for his friends. Remainig money = x - 198 - 4/12*(x-198)

= (1 - 4/12) of (x-198)

= 2/3 of (x-198)

John then put 2/9 if his remaining money into a checking account.

Now, the remaining money = 2/3*(x-198) - 2/9 of (x-198)

= (1 - 2/9) * 2/3*(x-198)

= 7/9 * 2/3*(x-198)

= 14/27(x-198)

Money left with him = $980

14/27(x-198) = $980

x - 198 = $980 * 27 / 14

x - 198 = 1890

x = 1890 + 198

x = 2088

Hence, John had $2088 originally in his savings accounts.

Answer: 2x-9y=1

Step-by-step explanation:

(this is how i found it don't know if this is how you learned it though)

Subtract 20 from both sides of -3x-8y=20, so that it becomes -3x-8y-20

Subtract 19 from both sides of -5x+y=19, so you get -5x+y-19

Subtract like terms from both equations (-3x-8y-20)-(-5x+y-19), which gives you 2x-9y-1

-3--5=2, -8-1=-9, -20--19=-1

Add 1 to both sides and you get 2x-9y=1

Answer:

Levi must sell more than 80000 cars per month for the new job to be better than the current job.

Step-by-step explanation:

New Job;

He receives $800 per month plus a commission of 2% or 0.02 of the total price of the cars.

Now, let the total amount he receives in a month be "y" and let the amount of cars sold be x.

Thus;

y = 800 + 0.02x - - - -(eq1)

Current Job:

He receives $1200 per month plus a commission of 1.5% or 0.015 of his total sales.

Thus;

y = 1200 + 0.015x - - - (eq2)

Substituting 800 + 0.02x for y into eq(2) gives;

800 + 0.02x = 1200 + 0.015x

0.02x - 0.015x = 1200 - 800

0.005x = 400

x = 400/0.005

x = 80000

This means Levi must sell more than 80000 cars per month for the new job to be better than the current job.

Answer:

the solutions are {1, -3/2}

Step-by-step explanation:

The given equation 2x^2 + x - 1 = 2 simplifies to 2x^2 + x - 3 = 0 if we subtract 2 from both sides.

We are told that -3/2 is a solution and must find the other solution   To do this, use synthetic division; if the remainder is zero, that tells us that -3/2 is actually a solution, and we can obtain the second solution easily, as follows:

-3/2     /     2       1        -3

                         -3        3

           -------------------------

                 2      -2        0

Since the remainder is 0, we have verified that -3/2 is a solution.  The coefficients of the other factor of the original equation are 2 and -2, and so this other factor is 2x - 2, or 2(x - 1).  Setting this result equal to zero yields x = 1.  

Thus the solutions are {1, -3/2}.

Answer:

112 ≤ T ≤ 158

Step-by-step explanation:

We need to convert the celsius temperature to Fahrenheit first.

The formula to use is

F = (C * 9/5) + 32

For 50 degrees Celsius

F = (50 * 9/5) + 32

= 90 + 32 = 112 F

For 70 degrees Celsius

F = (70 * 9/5) + 32

= 158 F

So the compound inequality is written as follows;

112 ≤ T ≤ 158

Step-by-step explanation:

i dont know how to do this i just used a website just copy your question into google search bar and look it up.

To covert a fraction to it's simplest form we need to divide their numerator and denominator with the same number .

= 16/40

= 16 ÷ 4 / 40 ÷ 4

= 4/10

= 4 ÷ 2 / 10 ÷ 2

= 2/5

Since both the numerator and denominator dont have a common factor , we can say that they are in their simplest form .

Therefore , the fraction 16/40 = 2/5

Answer:

32 and 40

Step-by-step explanation:

Let's call the smaller number x. If the smaller number is x, the equation for this problem is 2x + 8 = 72

Equation:

2x + 8 = 72

2x = 64

x = 32

So now we know the smaller number is 32, so now add 8 and we get 40.

Therefore the 2 numbers are 32 and 40

Answer:

Step-by-step explanation:

x^2 - 4x - 5 = 0

(x - 5)(x + 1) = 0

x - 5 = 0

x = 5

x + 1 = 0

x = -1

We want to find the roots of a quadratic equation, to do that, we will use the Bhaskara's formula.

For an equation like a*x^2 + b*x + c = 0

The solutions are given by:

[tex]x = \frac{-b \pm \sqrt{b^2 - 4*a*c} }{2*a}[/tex]

Using that formula we will get that the solutions in ascending order are -1 and 5.

Now let's see how to get that:

We have expression: x^2 - 4x = 5

We can rewrite this as:

x^2 - 4x - 5 = 0

Now we can use the Bhaskara's formula to get:

[tex]x = \frac{-(-4) \pm \sqrt{(-4)^2 - 4*1*(-5)} }{2*1} = \frac{4 \pm6}{2*1}[/tex]

Then the two solutions are:

x = (4 + 6)/2 = 5

x = (4 - 6)/2 = -1

Then the solutions in ascending order are -1 and 5.

bananas are  x -3

(2x–5)° + 45° = 180° (sum of consecutive interior angles

=> 2x + 40 = 180

=> 2x = 180– 40

=> x = 140 /2

=> x = 70

The required value of the x is 70 in the measures of the angle.

Given that Line m and n are parallel lines and intersect by a transversal line l.

When a transversal line intersects two other lines, it creates eight angles, four of which are called exterior angles and four are called interior angles.

From the sum of consecutive interior angles we have;

(2x–5)° + 45° = 180°

2x + 40 = 180

2x = 180– 40

x = 140 /2

x = 70
