If 8 cakes cost £4.00 how much would 3 cakes cost?

zzz [600]

Hello!

To calculate how much 3 cakes would cost, we must first find the cost of each individual cake.

To do this, we must divide the cost of 8 cakes by 8 cakes.

4.00 ÷ 8 = 0.5

This means that each individual cake costs $0.50. Multiply this by 3 to find the cost of 3 cakes.

0.50 × 3 = 1.50

Therefore, 3 cakes would cost $1.50.

6x=2x+44 solve for x

agasfer [191]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{x = 11}}}}}$

Step-by-step explanation:

$\sf{6x = 2x + 44}$

Move 2x to left hand side and change it's sign

⇒ $\sf{6x - 2x = 44}$

Collect like terms

⇒ $\sf{4x = 44}$

Divide both sides of the equation by 4

⇒ $\sf{ \frac{4x}{4} = \frac{44}{4} }$

Calculate

⇒ $\sf{x = 11}$

Hope I helped!

Best regards!!

Please help!!!! Sine and cosine ratios

Kipish [7]

Answer: 40.9

Step-by-step explanation:

Given

angle given is $23^{\circ}$

$RC=16$

Using trigonometry

$\Rightarrow \sin 23^{\circ}=\dfrac{RC}{PC}\\\\\Rightarrow \sin 23^{\circ}=\dfrac{16}{X}\\\\\Rightarrow X=\dfrac{16}{\sin 23^{\circ}}\\\\\Rightarrow X=40.948\approx 40.9$

Using cosine formula

$\Rightarrow \cos 23^{\circ}=\dfrac{PR}{X}\\\\\Rightarrow PR=40.9\times \cos 23^{\circ}\\\Rightarrow PR=37.69\approx 37.7$
