Answer:

x= -1.7

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

x = -1.7.

Step-by-step explanation:

3.7 = 5x + 12.2

Subtract 3.7 from both sides:

0 = 5x + 12.2 - 3.7

0 = 5x + 8.5

Subtract 5x from both sides:

-5x = 8.5

x = 8.5 / -5

x = -1.7.

Answer:

length = 6 cm; width = 5.5 cm

Step-by-step explanation:

Let the length = x. Let the width = y.

We use the formulas for area and perimeter using x and y, and the given values.

area = length * width

perimeter = 2(length + width)

xy = 33

2(x + y) = 23

Solve the first equation for x:

x = 33/y

Substitute 33/y for x in the second equation.

2(33/y + y) = 23

66/y + 2y = 23

Mulrtiply both sides by y.

66 + 2y^2 = 23y

2y^2 - 23y + 66 = 0

(2y - 11)(y - 6) = 0

2y - 11 = 0   or   y - 6 = 0

y = 11/2 = 5.5   or   y = 6

xy = 33

x * 11/2 = 33

x = 33 * 2/11

x = 6

Answer: length = 6 cm; width = 5.5 cm

Answer:

The amount of candy you had before is 8.

Step-by-step explanation:

75% + 25% makes 100% percent.

If we take 25% off from 8, you get 6.

A quick way to do this is: 8(.25)

If you solve that, you get 2. 8 - 2 is 6, which is what you originally had.

Answer:

y = 2x - 3

Step-by-step explanation:

Slope intercept form : y = mx + b

Answer: 7 - 2n

Step-by-step explanation:

a1 = 5

a6 = -5 = a + (n - 1)d = a + (6 - 1)d

a + 5d = -5

Since a1 = 5

5 + 5d = -5

5d = -5 - 5

5d = -10

d = -10/5

d = -2

Therefore, the equation to calculate the nth term of this sequence will be:

= a + (n-1)d

= a + (n - 1)-2

= 5 -2n +2

= 7 - 2n

Answer:

4

Step-by-step explanation:

f(x)=2x-4

Just plug in 4 into x. If you get confused on what f(x) means, it basically is the output value or the y value. So when plugging in the number for f(x), I recommend not worrying about the symbol f(x) too much.

Answer:

13 / 8

Step-by-step explanation:

Given that :

Length of board = 13 feets

Number of equal board section needed = 8

The largest possible length of 1 section of the board :

Answer:

$564

Step-by-step explanation:

6% of 600 is 36

So 600-36= $564

Answer: $564

Step-by-step explanation:

Here is the easy way to memorise the truth value of p ^ q.

p ^ q will be true only if p and q both are true. Otherwise, false.

Given p = x is prime and q = x is even. If we replace x by 2 then we would get

p = 2 is prime

q = 2 is even

The statement for p and q both are true because 2 only has two factors which are only 1 and 2 itself. 2 is also considered an even number (2,4,6,8,...)

Since p = true and q = true then p and q = p^q = true and true = T/True

The second choice. p^q is True

Answer:

$300.64

Step-by-step explanation:

Step one:

Given data

Jennifer had $256.86

She made a deposit of $43.78

Required

The total amount in the account

Step two:

To get the balance, we need to sum the previous amount with the deposited amount

Total= 256.86 +43.78

Total=$300.64

The balance is $300.64

Answer:

50.24 yards=Circumference

Step-by-step explanation:

So first the formula to find circumfence is π*diameter

The diamtere is 16

π is told to be counted as 3.14

3.14*16=50.24

So the Circumfrnce is 50.24

Answer: a) The size of angle x is [tex]80^{\circ}[/tex].

b)  A. Corresponding angles.

Step-by-step explanation:

Since AD is parallel to EH and CG is a transversal intersecting them at B and F, then [tex]\angle ABF = \angle EFG[/tex]  ...(i)

[Pair of corresponding angles are equal lie on the same side of the transversal]

Here, [tex]\angle EFG =80^{\circ}[/tex] , [tex]\angle ABF = x[/tex]

then, [tex]x =80^{\circ}[/tex]  [Substitute values in (i)]

Hence, the size of angle x is [tex]80^{\circ}[/tex].

Reason for this: Corresponding angles.

Answer:

Option (3)

Step-by-step explanation:

From the figure attached,

[tex]\frac{BC}{FD}=\frac{AC}{ED}[/tex]

[tex]\frac{3}{1}= \frac{3.9}{1.3}[/tex]

[tex]\frac{3}{1}= \frac{3}{1}[/tex]

Therefore, these corresponding sides are proportional (In the same ratio).

Angle between these sides are also equal. (Given in the picture)

Since, SAS rule of similarity states that, two triangles will be similar if their corresponding two sides are proportional and angle between these two sides are equal.

Option (3) will be the answer.
