Step 1: Find one term from both equations on the left side of the equality sign that, when added together, equal 0 (thus canceling each other out.) The two terms that fit this description is -y and y. Add them together we get 0.

Step 2: Add the remaining like terms from both equations.
3x + x = 4x
-5 + 1 = -4
4x = -4

Step 3: Divide both sides by 4 to isolate the variable x.
4/4x = -4/4
x = -1

Step 4: We have x, now we need to find y. Take an original equation (either one is fine) and substitute -1 for x. 
3(-1)⇒ -3 + y = 1

Step 5: Isolate 'y' by doing inverse operations to both sides of the equation.
-3 + 3 + y = 1 + 3 ⇒ y = 4

Answer: (-1,4)

viktelen [127]

Answer:

1125.

Step-by-step explanation:

I'm going to work out the answer is <u><em>grams</em></u>.

1kg = 1000g

0.225kg of butter = 225g, 225g of sugar, 225g of flour, 0.2kg of eggs = 200g, 250g of berries.

225 + 225 + 225 + 200 +250 = 1125.

Hope that helps. x

A man is 6 feet tall. To find the height of a tree, the shadow of the man and the shadow of the tree were measured. The length o
Sidana [21]

The answer is 16 ft because 6 ft tall over 4 feet 6 inches (4.5) is equal to x (tree's height) over 12 ft. You cross multiple and get 72 = 4.5x then you take 72 and divide by 4.5 to get the tree's height

\frac{6}{4.5}  =  \frac{x}{12}

Can you help me in my math work

The LCM of 18 and 24 using the prime-factorization method is <u>72</u>.

The LCM of 27, 81, and 54, using the division method is <u>162</u>.

In the first question, we are asked to find the LCM of the given numbers using the prime factorization method.

(i) 18, 24.

Prime factorization gives:

18 = 2*3², and 24 = 2³*3.

The LCM is the product of the highest power of each prime factor.

Thus, LCM = 2³*3² = 8*9 = 72.

Thus, the LCM of 18 and 24 using the prime-factorization method is <u>72</u>.

Doing similarly for other sub-parts, The LCM of:

(ii) 16, 40 is 80.

(iii) 30, 36 is 180.

(iv) 28, 44 is 308.

(v) 20, 32 is 160.

(vi) 20, 135 is 540.

(vii) 45, 75 is 225.

(viii) 36, 84 is 252.

(ix) 12, 18, 24 is 72.

(x) 25, 35, 45 is 1575.

(xi) 9, 15, 21 is 315.

(xii) 25, 50, 75 is 150.

In the second question, we are asked to find the LCM of the given numbers, using the division method.

(i) 27, 81, 54.

The division method gives:

\underline{2|27,81,54}\\\underline{3|27,81,27}\\\underline{3|9,27,9}\\\underline {3|3,9,3}\\\underline{3|1,3,1}\\{1|1,1,1}

The LCM is the product of all the numbers used for division.

LCM = 2*3*3*3*3*1 = 162.

Thus, the LCM of 27, 81, and 54, using the division method is <u>162</u>.

Doing similarly for other sub-parts, The LCM of:

(ii) 18, 45, 63 is 630.

(iii) 35, 55, 100 is 7700.

(iv) 210, 140, 315 is 1260.

(v) 112, 120, 150 is 8400.

(vi) 144, 180, 300 is 3600.
