Part A: (62)x=1

            62x= 1

              62x/62=1/62

Answer: $ 8

Step-by-step explanation:

Given: Original cost of camera =  $5

mark up percent = 60% = 0.60

Mark up value =60% of Original cost

Now , price of one camera= Original cost + Mark up value

= Original cost + 60% of Original cost

= $ (5+0.60(5))

= $ (5+3)

= $ 8

Hence,  price of one camera= $ 8

Answer:  16 weeks

Step-by-step explanation:

If y represents the amount of money left in her account, then left y be $145 in the equation and solve for x.  

145 = -27x + 557

-557              -557

  -432 = -27x  

 x =  16

Answer:

Circumcenter

Step-by-step explanation:

Answer:

24 miles

Step-by-step explanation:

Set up a proportion:

3 inches/1.25 miles = x inches/10 miles

Then cross multiply

30=1.25x

Divide 1.25 on both sides

x=24

Answer:

Garage A- 3x12+10=46

Garage B- 4x12+3=51

Garage A is $5 cheaper than Garage B when parking for 12 hours

Step-by-step explanation:

You plug in the variables given to each garage into y=mx+b. Both Garage A and B have a constant (A-$10, B-$3). X in this equation would be the number of hours and m is the amount charged per hour.

Answer:

[tex]\frac{3}{5}x=30[/tex] or [tex]\frac{3}{5}(\frac{5}{3})x=30(\frac{5}{3})[/tex] or x = 50

Step-by-step explanation:

(6) QP = QR therefore, triangle QPR is an isosceles triangle.

Since QPR is an isosceles triangle, the base angles are equal.

angle P + angle R + 80 = 180

2x + 80 = 180

2x = 100

x = 50.

That is just the measure of the base angle.

Now take triangle TSR.

Since R = 50, due to angle sum property, we can come up with this equation:

50 + 85 + x = 180

x = 180 - 135

x = 45 <- That's the answer.

(8) Take triangle PSQ, you get angle P = 70 degrees using the angle sum property and algebra.

Now take triangle PSR and you get angle P in the triangle as (180 - 100) / 2 = 40.

Since P = 70, and P in the smaller triangle is 40, 70 - 40 would be the answer.

x = 30 degrees <- That's the answer :D

Given:

Amount deposited on birth = $10,000.

Interest rate = 5% compound quarterly.

To find:

The balance on the person's 18th birthday.

Solution:

The formula for amount is

[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]

where, P is principal, r is rate of interest, n is number of times interest compounded in an year and t is number of years.

Substitute P=10000, r=0.05, n=4, t=18 in the above formula.

[tex]A=10000\left(1+\dfrac{0.05}{4}\right)^{4(18)}[/tex]

[tex]A=10000\left(1+0.0125\right)^{72}[/tex]

[tex]A=10000\left(1.0125\right)^{72}[/tex]

[tex]A=24459.2026814[/tex]

[tex]A\approx 24459.20[/tex]

Therefore, the balance on the person's 18th birthday is $24459.20.

x/2 - 9 = -9

Answer:

Step-by-step explanation:

1 km = 1,000 m = 100,000 cm = 1,000,000 mm

1 mm is millionth part of 1 km

1 mm = 0.000001 km

20 mm = 0.00002 km

Answer:

[tex]y = -2x+4[/tex]

Step-by-step explanation:

Linear equations can be written in the form [tex]y=mx+b[/tex] where [tex]m[/tex] is the gradient/slope and [tex]b[/tex] is the y-intercept of the line.

With the given slope and y-intercept, the linear equation of the line can be written as [tex]y=-2x+4[/tex].

Answer:

The answer is 5n-2 so the 3rd choice.

Answer: 5n-2

Step-by-step explanation:

2 less than: means to put -2 at the end

product of 5 and a number: means that you're multiplying 5 and n (5n

So, you end up with C. 5n-2

Answer:

48

Step-by-step explanation:

Bridget = 2      x 12 = 24

Jim = 1              x 12 = 12

Krutika = 1        x 12 = 12        ---> 24 + 12 + 12 = 48

Step-by-step explanation:

Answer:

[tex]\huge\boxed{\sf 126\° \ OR \ 145 \°}[/tex]

Step-by-step explanation:

m∠4 + m∠7 = 180    (Adjacent Angles of a parallelogram)

Given that m∠4 = x + 45, m∠7 = x² + 45

x + 45 + x² + 45 = 180

x² + x + 90 = 180

x² + x = 180 - 90

x² + x = 90

x² + x - 90 = 0

Using mid-term break formula

x² + 10x - 9x - 90 = 0

x(x+10) - 9(x+10) = 0

(x - 9)(x + 10) = 0

Either,

x-9 = 0       OR      x+10 = 0

x = 9          OR        x = -10

[tex]\rule[225]{225}{2}[/tex]

Now,

m < 7 = x² + 45

For x = 9

m < 7 = (9)² + 45

m < 7 = 81 + 45

For x = -10

m < 7 = (-10)² + 45

m < 7 = 100 + 45

[tex]\rule[225]{225}{2}[/tex]

Answer:

A. No

B. Yes

C. No

D. Yes

E. Yes

Step-by-step explanation:

3(x + 2) = 3x + 6

A. 3x + 2 is not 3x + 6

B. 3(2 + x) = 6 + 3x is equal to 3x + 6

C. 3x + 2x is not the same as 3x + 6

D. x + 2x + 2 + 4 = 3x + 6 is equal to 3x + 6

E. x + x + x + 1 + 1 + 1 + 1 + 1 + 1 = 3x + 6 is the same as 3x + 6
