Answer:

16 cards were left in the stack.

Step-by-step explanation:

27 to begin with + 6 that Cate added - 10 that Elena took - 7 that Cate took.

27 + 6 - 10 - 7 = 16

Answer:

Step-by-step explanation:

(x₁ , y₁) = (6, -4)  &    (x₂ , y₂) =(-1 , -4)

In these two points, there is no change in y-coordinates. So, the line is parallel to x-axis.

Slope of line parallel to x-axis = 0

yo bro math sucks you feel me

Answer:

c options is right what is the answer

Answer:

F = FIRST TERM

S = SECOND TERM

L = LAST TERM

Step-by-step explanation:

1- (x+1)² = x²+2x+1

F = x²

S = 2x

L = 1

2- (x+2)² = x² + 4x + 4

F = x²

S = 4x

L = 4

3- (x+3)² = x² + 6x +9

F = x²

S= 6x

L= 9

4 (x+ y)² = x²+2xy +y²

F = x²

S = 2xy

L = y²

Answer:

a=1 D

Step-by-step explanation:

insert x=1 in the equation

Answer:

When it is divided by x-1 and it has no remainder , then it means substituting x=1 into the polynomial is zero .Because x-1 is a factor.

[tex]2 {x}^{3} - a {x}^{2} - 7x + 6 \\ x = 1 \\ 2 {(1)}^{3} - a {(1)}^{2} - 7(1) + 6 = 0 \\ 2 - a - 7 + 6 = 0 \\ 1 - a = 0 \\ a = 1[/tex]

Answer:

1/8 = 0.125

14/20 = 0.7

2/3 = 0.67

4/5 = 0.8

Step-by-step explanation:

Answer:

m - 4m = 2m

-4 = 2m -m

- 2 = m

Answer:

m = -4

Step-by-step explanation:

Add 4 to both sides of the equation

Simplify

Add the numbers

= 2 + 4

Subtract 2 from both sides of the equation

=2+4

−2=2+4−2

Simplify

Divide both sides of the equation by the same term

Simplify

Answer: 12 servings with one pint.

1 pint = 2 cups

Step-by-step explanation:

5 cups make 30 servings, 2 cups make x servings

5/30 = 2/x (cross multiplication)

(30 * 2)/5 = 12

Answer:

[tex] \frac{1}{15} x[/tex]

Step-by-step explanation:

[tex] \frac{7x}{20} - \frac{5x}{12} [/tex]

[tex] \frac{3 \times 7x}{3 \times 20} - \frac{5 \times 5x}{5 \times 12} [/tex]

[tex] \frac{21x}{60} - \frac{25x}{60} [/tex]

[tex] \frac{21x - 25x}{60} = (21 - 25)x = - 4x[/tex]

[tex] \frac{ - 4x}{60} = - \frac{ x}{15} [/tex]

[tex]\boxed{\green{= \frac{1}{15} x}}[/tex]

Answer:

you must send 25 msgs to have the same cost

Step-by-step explanation:

x = n of messages

15+ (0.25x ) = 20 + (0.05x)

0.2x = 5

x = 25

Answer:

at 25 text the plan costs are equal

Step-by-step explanation:

Plan A = $15 + .25t

Plan B = $20 + .05t

when the plan costs are equal $A = $B

then

15 + .25t = 20 + .05t

.25t - .05t = 20 - 15

.2t = 5

t = 25

Answer:

$270

Step-by-step explanation:

The opening deposit is $150.

Every month receives $10.

In 12 months it gets 12 x $10 = $120 additional money.

So together with the opening deposit at the end of 1 year the account has

$150 + $120 = $270

Answer:

Step-by-step explanation:

Answer:

15. x = 112 degrees

18. x = 120 degrees

Step-by-step explanation:

15.

A triangle's angles always equal 180 degrees so we can find the two unknown angles by subtracting 44 from 180 and then dividing it by 2.

2a + 44 = 180

2a = 136

a = 68

Each unknown angle equals 68 degrees. The line from 44 degrees to x degrees segments a line that has a 180 degree angle so we can subtract 68 from 180 to get x.

x + 68 = 180

x = 112

18.

We can use the same concept here but now every angle equals each other so we can divide 180 by 3 to get the measure of those angles.

3a = 180

a = 60

Now we do the same thing as last time to find x.

x + 60 = 180

x = 120

Answer:

9.50 + 0.20e = 12.50

Step-by-step explanation:

you start with the 9.50, base price. Then with every photo you pay 0.20, since we don't know how many it is we put a variable. Then we know that those two combined is 12.50, so yeah.

Answer:

Step-by-step explanation:

Total Cost = base price + 0.20*x   Where x is the number of prints printed.

12.50 = 9.50 + 0.20x                      Subtract 9.50 from both sides.

12.50 - 9.50 = 0.20x

3 = 0.20x                                         Divide by 0.20

3/0.20 = x

x = 15

So he printed 15 prints.

System of Linear Equations entered :

[1] y - 2x/3 = -1

[2] y + x = 4

// To remove fractions, multiply equations by their respective LCD

Multiply equation [1] by 3

// Equations now take the shape:

[1] 3y - 2x = -3

[2] y + x = 4

Graphic Representation of the Equations :

-2x + 3y = -3 x + y = 4

Solve by Substitution :

// Solve equation [2] for the variable x

[2] x = -y + 4

// Plug this in for variable x in equation [1]

[1] 3y - 2•(-y +4) = -3

[1] 5y = 5

// Solve equation [1] for the variable y

[1] 5y = 5

[1] y = 1

// By now we know this much :

y = 1

x = -y+4

// Use the y value to solve for x

x = -(1)+4 = 3

Answer:

l = 12 is the answer

Answer:

B, L=12

Step-by-step explanation:

Simple two-step. first you ignore addition sign, (there to trick ya) so L-3=9

then you need L by itself so add three to both sides and you'll be done.

L=12

Answer:

-1

Step-by-step explanation:

We can find the slope using the slope formula
