Answer:

x=8

Step-by-step explanation:

4x+10 = 2x+26

4x-2x+10=2x-2x+26  [Subtract 2x from both sides]

2x+10=26

2x + 10 - 10 = 26 - 10  [Subtract 10 from both sides]

2x = 1

2x/2 = 16/2  [Divide both sides by 2]

x = 8

CHECK:

Does 4x+10 = 2x+26 when x is 8?

4(8)+10 = 2*(8)+26  ?

32+10 = 16+26    ?

42 = 42   YES

Answer:

[tex]\large \boxed{\sf x =8}[/tex]

Explanation:

[tex]\sf \rightarrow 4x + 10 = 2x + 26[/tex]

collect like terms

[tex]\sf \rightarrow 4x -2x = 26-10[/tex]

subtract like terms

[tex]\sf \rightarrow 2x = 16[/tex]

divide both sides by 2

[tex]\sf \rightarrow x = 8[/tex]

Answer:

20 mph

Step-by-step explanation:

First problem:

The new speed is 26 mph.

The old speed was x.

The new speed is 30% higher than the old speed.

1.3x = 26

x = 20

Answer: 20 mph

Second problem:

A number, perhaps a percent or a fraction, is missing from the problem.

Given expression

[tex]\\ \rm\Rrightarrow T(t)=29-5cos\left(\cfrac{2\pi (t-12)}{365}\right)[/tex]

Now

We know according to property of cosine function

This property is enough for our calculations

Let's check

As t represents no of days hence it can't be negative

So

for positive interval

We know that

Hence it's enough for our range [-1,1]

Now

In the expression

Let

[tex]\sf cos\left(\cfrac{2\pi(t-12)}{365}\right)=n[/tex]

Substitute n for lowest and highest value of range

When n=-1

[tex]\\ \rm\Rrightarrow T(\pi)=29-5(-1)=29+5=34°C[/tex]

When n=1

[tex]\\ \rm\Rrightarrow T(0)=29-5(1)=29-5=24°C[/tex]

Answer:

Highest temperature: 34°C

Lowest temperature: 24°C

Explanation:

In a Normal Trigonometry Function: y = A + B sin(x) or y = A + B cos(x)

Maximum value: A + |B|

Minimum value: A - |B|

In this trigonometric function, A = 29, B = -5

Hence find minimum/maximum:

Maximum value: A + |B| = 29 + |-5| = 34

Minimum value: A - |B| = 29 - |-5| = 24

Hence, the maximum/highest temperature is 34°C and minimum/lowest temperature is 24°C in Karachi, Pakistan.

Answer:

True

9 * 7 = 63

Therefore when x=7 9x=63

The equation given is true since 7 is the solution.

An equation is the statement of two expressions located on two sides connected with an equal to sign.

The two sides of an equation is usually called as left hand side and right hand side.

The given equation is 9x = 63.

There is only one variable here, x.

We have to solve this equation and find whether the solution is 7 or not.

Solution of the equation is the value of x.

9x = 63

Divide both sides of the equation by 9, then, we get,

9x / 9 = 63 / 9

9 gets cancelled in the left hand side and 63/9 = 7.

So we get,

x = 7

So the given statement is true that for 9x = 63, the solution is x = 7.

Hence the given equation is true.

Each pizza cost $ 12.65

An Equation is used in determination of unknown variables in an expression .

It is given that

Brian ordered 3 large cheese pizzas and a salad.

The salad cost $4.95

Total amount spend = $47.60

Tip = $5

The amount spend in food is $ 47.60-5

= $42.60

Let the price of Pizza is x then the equation that can be formed to determine the price of pizza is

3x + salad = 42.60

3x + 4.95 = 42.60

3x = 37.65

Answer:

8

Step-by-step explanation:

If the only zero for this function is at x = - 4 it looks like this:

f(x)  = (x+4)(x+4)        =    x^2 +8x + 16         so j = 8

Answer:

Step-by-step explanation:

x² +jx +k = 0

If there is only one root ( - 4 ), then (x + 4)² = 0

Answer: The coefficients of binomial expansions are calculated using Pascal's triangle.

Answer:

missing side lengths are

leg 1 is 4√2

leg 2 is 4√2

hypotenuse is 8

Step-by-step explanation:

leg 1 is y

leg 2 is 4√2

45-45-90 right triangle means

legs are equal

the longest side is the hypotenuse which is

x

pythagorean theorem =

a² + b² = c²

a and b are the legs

c is hypotenuse

(4√2)² + (4√2)² = c²

4√2 = √16*2 = √32

(√32)² + (√32)² = c²

32 + 32 = c²

64 = c²

take the square root of both sides

√64 = √c²

8 = c

c = 8

Step-by-step explanation:

Sarah charges $6.00 for one bracelet.

We know that a collection of one or more linear equations containing the same variables is known as a system of linear equations in mathematics.

Let Sarah charges $x and $y for one bracelet and one ring respectively.

Since her first customer spends $48 on 3 bracelets and 10 rings, we can write it as

3x + 10y = 48 ...(1)

Since her second customer spends $54 on 7 bracelets and 4 rings, we can write it as

7x + 4y = 54 ...(2)

Now, we have to solve this system of linear equations.

Multiplying (1) by 2, 6x + 20y = 96 ...(3)

Multiplying (2) by 5, 35x + 20y = 270 ...(4)

Subtracting (3) from (4), 35x + 20y - 6x - 20y = 270 - 96

i.e. 29x = 174

i.e. x = 174/29 = 6

Therefore we can conclude that Sarah charges $6 for one bracelet. Option B is correct.

A fourth of a third of two fifths is a thirtieth.

(1 x 1 x 2) / (4 x 3 x 5) = 2 / 60 = 1 / 30

A thirtieth of a number () is fifteen, the number is four hundred and fifty.

= 15 / (1 / 30) = 15 x 30 = 450

forty percent of four hundred and fifty is one hundred and eighty.

(450 / 100) x 40 = 180

Answer:

The number is 450

Step-by-step explanation:

One fourth is 1/4,

One third is 1/3

and two fifths is 2/5

let the number be x.

So,

One fourth of one third of two fifths of x is 15.

that is,

1/4 * 1/3 * 2/5 * x = 15

2/4*3*5* x = 15

2/60 * x = 15

1/30 * x = 15

1 * x = 15*30

x = 450
