Answer: 12=7−3x+5x

Step 1: Simplify both sides of the equation.

12=7−3x+5x

12=7+−3x+5x

12=(−3x+5x)+(7)(Combine Like Terms)

12=2x+7

12=2x+7

Step 2: Flip the equation.

2x+7=12

Step 3: Subtract 7 from both sides.

2x+7−7=12−7

2x=5

Step 4: Divide both sides by 2.

Step-by-step explanation:

Given that :

Let Cost of hats = h

Cost of scarves = 1.5h

Hence if hats cost $h, then the cost of scarves will be; (1.5 * h)

Using tables :

If the cost of an hat = $2

Hence,

N _____cost of hat(h) ____cost of scarve

1_______2*1 = 2 _________1.5(2) = 3

2______2 *2 = 4 _________1.5(4) = 6

3______2*3 = 6 _________1.5(6) = 9

4 ______ 2*4 = 8 ________1.5(8) = 12

5 ______2 *5=10 ________1.5(10) = 15

Cost of 6 hats and scarve:

Cost of hat:

2 * 6 = $12

1.5h = 1.5(12) = $18

m = 0

Step-by-step explanation:

If it's written in y =mx + c form, x is 0 and so is m.

Thus, m should be 0

Answer:

To find GCD or HCF, just write the common factor.

Step-by-step explanation:

To find the GCF of greater numbers, you can factor each number to find their prime factors, identify the prime factors they have in common, and then multiply those together.

Answer:

64

Step-by-step explanation:

Let x represent the number.

x + 23 represents 23 added to the number.

2x - 41 represents 41 less than twice the number.

Set these expressions equal to each other and solve for x to find the number:

x + 23 = 2x - 41

23 = x - 41

64 = x

So, the number is 64

Answer:

Step-by-step explanation:

a) sum of angle on the straight line TRW is 180.

Given <TRS = 2x+10

<SRW = x-10

<TRS+<SRW = 180

2x+10+x-10 = 180

3x = 180

x = 180/3

x = 60°

<TRV = 180°-(2x+10)

Substitute x = 60° into the expression

<TRV = 180-(2(60)+10)

<TRV = 180-(120+10)

<TRV = 180-130

<TRV = 50°

2) From the diagram attached <MHJ= <LHK (oppositely directed angle)

Given

<MHJ= x+15

<LHK = 2x-20

Substitute the given data into the formula to get x

x+15= 2x-20

x-2x = -15-20

-x = -35

x = 35°

Next is to get the measure of <MHJ

<MHJ = x+15

<MHJ = 35+15

<MHJ = 50°

Answer:

a)Step-by-step explanation:If we put all of it together we have the factors 3 x 5 x 5 x 5 = 375. It can also be written in exponential form as 31 x 53

b)the highest common factor of 375 is 3X5X5X5

the highest common factor of 150 is 3X5X2X5

Step-by-step explanation:

first you have to multiply 2 and x, which is 2x

And Then you do 2x-3 which is -x

Answer:

YZ = 25.40 correct to 1dp

Step-by-Step explanation:

Sin16°= XZ/YZ

YZ=XZ/sin16°

YZ=7/0.276

YZ=25.3623188405797

YZ = 25.40 correct to 1dp

Answer:

XZ ≈ 24.39

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan16° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{XZ}{YZ}[/tex] = [tex]\frac{7}{YZ}[/tex] ( multiply both sides by YZ )

YZ × tan16° = 7

YZ × 0.287 = 7 ( divide both sides by 0.287 )

YZ = [tex]\frac{7}{0.287}[/tex] ≈ 24.39 ( to 2 dec. places )

Answer:

Step-by-step explanation:

This problem is on compound interest.

the expression for compound interest is given as

A=P(1+r)^t

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

Given data

P= $2,500

r= 10/100= 0.1

t= 30 years

substituting into the expression for compound interest and solving for A we have

A=2500(1+0.1)^30

A=2500(1.1)^30

A=2500*17.449

A=$43623.50

The final amount is $43623.50

-16x = - 352     divide by -16 both sides

x = -352/-16

x = 22

Answer:−16x=−352

Divide both sides by −16.

x=  −352/−16

Divide −352 by −16 to get 22.

x=22

The value in index form is [tex]5^{18}[/tex]

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

[tex](5^3)^6[/tex]

= [tex]5^{3\times6}[/tex]
