Answer:

Gold square = 4

Blue triangle = 3

Step-by-step explanation:

Red hexagon = 6, and there are 4 red hexagons.  So the total is 24.

Therefore, the total on the other side must also be 24.

That means the 4 blue triangles add up to 12, and the 3 gold squares add up to 12.

So each blue triangle is 3, and each gold square is 4.

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°

☆The sum of angles on a straight line is 180°

☆ The sum of angles in a triangle is 180°

Answer:

1/5 pint

Step-by-step explanation:

given:

Amount of Glue needed = 9/10 pints

Amount of Glue available = 7/10 pints

Amount of extra glue needed = Amount of glue needed - Amount of Glue Available

= 9/10 - 7/10

= (9-7)/10

= 2/10   (simplify by dividing both numerator and denominator by 2)

= 1/5 pint

Answer:

x = 32

y = 60

Step-by-step explanation:

By plugging in the equation and solving it, we end up with 32. Then, plugging in 32 for x we get 60 for y when solved.

6y+8 = 7y-12

subtract 8 from both sides

6y = 7y - 12

subtract 7y from both sides

-y = -20

y = 20

4x = 6x-26

subtract 6x from both sides

-2x = -26

x = 13

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.

Answer:

The meaning theatrical releases means the date a new movie is entered into the theater distribution system for public viewing. Alternate formats of the movie, such as DVDs, Blu-ray discs and video-on-demand, are scheduled for distribution a set number of weeks or months after the theatrical release. See video-on-demand. So if that is what it means then the movie i think that has 7 theatrical releases is the new movie "Mulan" because the people started making the movie on March 9th, 2020 and released the movie on September 4th, 2020. If i am incorrect i apologize

Answer:

What value of x makes this equation true? 2(4x-3) - 8= 4+2x​  HERE YOU GO!!

Step-by-step explanation:

We need to eliminate one of the variables to solve the other.

4x+5y = 8

2x-3y = 18

I will multiply the second equation by -2.

-2*(2x-3y = 18)

-4x + 6y = -36 and then add the two equations

4x + 5y = 8

-4x + 6y = -36

+ adding here

11y = -24

y = -24/11

substitute x in one of the equations to find y.

2x-3y=18

2x - (3*-24/11) = 18

2x = 126/11

x = 126/22

Answer:

$15.60

Step-by-step explanation:

We can solve this problem easily by adding up Miguel's expenses, and then subtracting them from the amount he started with. Be careful, as he pays $4, not $2, in total for bus fare, because he is paying $2 to and from:

[tex]6.75+3.65+4.00[/tex]

[tex]=14.40[/tex]

Let's subtract our sum, [tex]14.40[/tex], from our total, [tex]30[/tex]:

[tex]30-14.40[/tex]

[tex]=15.60[/tex]

Miguel has $15.60 left.

Answer:

If you can only pick one option I'd choose D.)

Step-by-step explanation:

Option D is only two numbers away from 456,700

The second closest number would be option B.)

Answer:

[tex]D) . \: 456,698 = 456,700 \: to \: the \: hundreds \: place.[/tex]

(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

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:

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.
