Answer:

This can be solved like this:

4x-3x+9=20

<em>Solving 4x-3x</em>

x+9=20

Transposing +9

x=20-9

And now we have, x=11

Answer:

x=11

Step-by-step explanation:

first solve the things you can simplify on one side of the equation:

4x-3x+9=20--->x+9=20

then, get the variables onto one side of the equation and numbers unto the other.

*minus 9 from each side*

x=11

Triangle S R Q is shown. Angle S R Q is a right angle. An altitude is drawn from point R to point T on side S Q to form a right

Jet001 [13]

Answer:

Option B.

Step-by-step explanation:

It is given that ΔSRQ is a right angle triangle, ∠SRQ is right angle.

RT is altitude on side SQ, ST=9, TQ=16 and SR=x.

In ΔSRQ and ΔSTR,

$m\angle S=m\angle S$ (Reflexive property)

$m\angle R=m\angle T$ (Right angle)

By AA property of similarity,

$\triangle SRQ\sim \triangle STR$

Corresponding parts of similar triangles are proportional.

$\dfrac{SR}{SQ}=\dfrac{ST}{SR}$

Substitute the given values.

$\dfrac{x}{9+16}=\dfrac{9}{x}$

$\dfrac{x}{25}=\dfrac{9}{x}$

On cross multiplication we get

$x^2=25\times 9$

$x^2=225$

Taking square root on both sides.

$x=\sqrt{225}$

$x=15$

The value of x is 15. Therefore, the correct option is B.

Sarah is making lemonade where she adds 2 parts lemon juice to 3 parts water.

Vladimir79 [104]

Answer: 6 CUP LEMON

2 part lemon +3part water = 5parts of mix

2part lemon = 3 part water so ratios are:

(2lemon/3wateer) = 1, and also (3water/2lemon) = 1

For 112c lemon (3 water/2lemon) = 3*51= 153 parts water

9c water (2 lemon/3water) = 6 cup lemon
