Step-by-step explanation below.

24.5 - 12 = 12.5

Step-by-step explanation:

let number be X

X - 12 = 12.5

x = 12.5 + 12

x = 24.5

Answer:

Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.

Point Form:

(0,2)

Equation Form:x=0, y=2

Answer:

(0,2)

Step-by-step explanation:

Multiply each equation by the value that makes the coefficients of  y  opposite.

3*2x-y=3*-2

Simplify

6x-3y=-6

Add the two equations

10x = 0

Divide both by 10 and simplify

x=0

Substitute x into the equations.

4*0+3y=6

3y=6

2

y=2

Answer:

2067in

Step-by-step explanation:

26x26x2=1352

494+221+1352=2067

Answer: 710,000 kg

Step-by-step explanation:

There are 100 pence in one pound.

The number of two pence coins in 1 pound is therefore:

= 100 / 2

= 50 coins

In 2 million pounds therefore, there will be:

= 50 * 2,000,000

= 100,000,000 two pence coins

If one coin weighs 7.1g, weight is:

= 100,000,000 * 7.1

= 710,000,000 g

A kg is 1,000 grams so the weight in kg is:

= 710,000,000/1,000

= 710,000 kg

Answer:

5) x = 12 6) y = 3.5

For number 6 that one may be right I tried several ways and kept getting that answer

5. is completely write though

Hope that helps

Answer:

Question 5: x = 12, Question 6: y = 2[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Use the Pythagorean Theorem to calculate missing sides.

Question 5 explanation: [tex]x^{2} + 9^2 = 15^2[/tex]n:  ⇒ [tex]x^{2} + 81 = 225[/tex] ⇒ [tex]x^{2} = 144[/tex] ⇒ [tex]x=12[/tex]

Answer:

Pack of 6

Step-by-step explanation:

Pack of 4 = £1

Packs of 6 = £1.20

Price per unit of each pack:

Pack of 4 ;

Unit price : cost / units

Unit price = £1 / 4 = £0.25

Pack of 6 ;

Unit price : cost / units

Unit price = £1.20 / 6 = £0.20

Pack of 6 is the best value for money as it has a lower unit price

Answer:

38.57 feets

Step-by-step explanation:

Given that:

Height of monument, h = 300ft

Shadow of monument, s = 210 ft

Shadow of tree, s = 27ft

Height of tree, = x

Using the relation :

Height / shadow = height / shadow

Monument = tree

300 / 210 = h / 27

Cross multiply

300 * 27 = 210 * h

8100 = 210h

h = 8100 / 210

h = 38.57 feets

Answer:

36.24

Step-by-step explanation:

- 3 * 2 = - 6

73 / 76 = 0.96

0.96 * (-6) = -5.76

42 - 5.76 = 36.24

Step-by-step explanation:

Answer:

6 elephants and 3 kangaroos in the zoo.

Step-by-step explanation:

Number of animals = 9

Number of legs seen = 30

But an elephant has 4 legs, while a kangaroo has 2 legs.

Let the number of elephant be represented by E, and the number of kangaroo by K.

So that,

E + K = 9 .................. 1

4E + 2K = 30 ............. 2

Multiply equation 1 by 2 to have

2E + 2K = 18 ............ 3

Subtract equation 3 from 1

2E = 12

E = 6

Substitute the value of E in equation 1

E + K = 9

6 + K = 9

k = 3

Thus, there were 6 elephants and 3 kangaroos in the zoo.

Answer:

317.52

Step-by-step explanation:

Label the point where the altitude meets the base P and the end points of the base A and B where m∠A = 27 and m∠B = 41

tan 27 = 102/AP    and tan 41 = 102/PB

APtan 27 = 102            PBtan 41 = 102

AP = 102/tan 27                 PB =  102/tan 41

AP = 200.186                     PB = 117.338

x = AP + PB = 200.186 + 117.338 = 317.52

Answer:

Option B. 8

Step-by-step explanation:
