ANSWER

$- 7 \sqrt{6}$

EXPLANATION

The given radical expression is

$3 \sqrt{6} - 10 \sqrt{2} \times \sqrt{3}$

Recall and use

$\sqrt{a} \times \sqrt{b} = \sqrt{ab}$

to obtain;

$3 \sqrt{6} -10 \sqrt{2 \times 3}$

Simplify the second radicand.

$3 \sqrt{6} - 10 \sqrt{6}$

We have two like surds so we can simplify to obtain;

$- 7 \sqrt{6}$

sara has a recipe for a cake that her mother gave her. the recipe calls for 3/4 cups of sugar for each cake. sara and her friend

Sara is wrong because making 3 cakes instead of 1 would require 2 1/4 cups of sugar. The original 3/4 cups of sugar would be multiplied by 3 (3/1 x 3/4) which would be 9/4, or 2 1/4, cups.

Solve the equation. Check your answer.<br> 6x - 3= 5x +5<br> X=

ZanzabumX [31]

Answer:

x = 8

Step-by-step explanation:

6x - 3 = 5x + 5

Move variable to the left hand side and change their sign.

$\sf \: 6x - 5x - 3 = 5$

Calculate like terms.

x - 3 = 5.

Move constant to the right hand side and change their sign.

x = 5 + 3
x = 8

<u>Check our answer :-</u>

6x -3 = 5x + 5

plug the 8 as x.

6 ( 8 ) - 3 = 5 ( 8 ) + 5
48 - 3 = 40 + 5
45 = 45

LHS = RHS
