If 6 cakes cost £1.80, how much do 4 cost

1 answer:

8 0

First find the value of 1 cake by dividing the price of all six by six. £1.80/6 can be seen more simply as 180p/6 which is 30p. Therefore 1 cake is 30p. Then multiply it with 4
which is 120

Verdich [7]

Answer:

The % students going to higher education is 79.60 % which is higher than the reported value.

Step-by-step explanation:

According to national study report the students going to college for higher education = 75 %

Given that

156 of their 196 graduates last year went on to college.

% students going to higher education is

$(\frac{156}{196}) 100 = 79.60$

Thus the % students going to higher education is 79.60 % which is higher than the reported value.

3a x 5b x 7c = 39375, then find value of 7a - 2b + 3c

garik1379 [7]

Answer:

Step-by-step explanation:

Simplifying

(7a + -2b) + -1[2(3a + -1c) + -3(2b + -3c)] = 0

Remove parenthesis around (7a + -2b)

7a + -2b + -1[2(3a + -1c) + -3(2b + -3c)] = 0

7a + -2b + -1[(3a * 2 + -1c * 2) + -3(2b + -3c)] = 0

7a + -2b + -1[(6a + -2c) + -3(2b + -3c)] = 0

7a + -2b + -1[6a + -2c + (2b * -3 + -3c * -3)] = 0

7a + -2b + -1[6a + -2c + (-6b + 9c)] = 0

Reorder the terms:

7a + -2b + -1[6a + -6b + -2c + 9c] = 0

Combine like terms: -2c + 9c = 7c

7a + -2b + -1[6a + -6b + 7c] = 0

7a + -2b + [6a * -1 + -6b * -1 + 7c * -1] = 0

7a + -2b + [-6a + 6b + -7c] = 0

Reorder the terms:

7a + -6a + -2b + 6b + -7c = 0

Combine like terms: 7a + -6a = 1a

1a + -2b + 6b + -7c = 0

Combine like terms: -2b + 6b = 4b

1a + 4b + -7c = 0

Solving

1a + 4b + -7c = 0

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-4b' to each side of the equation.

1a + 4b + -4b + -7c = 0 + -4b

Combine like terms: 4b + -4b = 0

1a + 0 + -7c = 0 + -4b

1a + -7c = 0 + -4b

Remove the zero:

1a + -7c = -4b

Add '7c' to each side of the equation.

1a + -7c + 7c = -4b + 7c

Combine like terms: -7c + 7c = 0

1a + 0 = -4b + 7c

1a = -4b + 7c

Divide each side by '1'.

a = -4b + 7c

Simplifying

a = -4b + 7c

Please answer correctly !!!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!!

Snezhnost [94]

Answer:

$\boxed {\boxed {\sf 1. \ 20 }}$

Step-by-step explanation:

An equilateral triangle has 3 equal sides and angles. Remember that <em>equil</em>ateral sounds like equal.

The interior angles of a triangle must equal 180 degrees.

All 3 angles are the same.
180/3= 60
All 3 angles in an equilateral triangle equal 60 degrees.

The question tells us the angle is equal to (4x-20).

∠= 60°
∠= (4x-20)°

So, by substitution, we can set 60 and (4x-20) equal to each other.

$60=4x-20$

Now, solve for x by isolating the variable on one side of the equation.

20 is being subtracted from 4x and the inverse operation of subtraction is addition. Add 20 to both sides of the equation.

$20+60=4x-20+20 \\ 20+60=4x\\80=4x$

x is being multiplied by 4. The inverse operation of multiplication is division. Divide both sides of the equation by 4.

$\frac{80}{4}=\frac{4x}{4}$

$\frac{80}{4}=x \\\ 20=x$

x is equal to 20 and choice 1 is correct.
