Create equivalent expressions in the equation that all have equal bases.72(3x)=73(2x+1)72(3x)=73(2x+1)Since the bases are the same, then two expressions are only equal if the exponents are also equal.2(3x)=3(2x+1)

Geometry hw!!! picture is above

AnnZ [28]

X=12 because 73-3x=61-2x so add 3x to both to make 73=61+X then subtract 61 from both to get 12=X

If point k is at (-3,2) where will it be when it is reflected over the line y=1 and then rotated 90 degrees?

Andrei [34K]

Answer:

(0,-3)

Step-by-step explanation:

(-3,2) reflected over the line y=1 is (-3,0)

Now rotated 90 degrees over what, and in which direction?

Im going to assume that the rotation is counter clockwise over the origin because that is standard when not mentioned. ¯\_(ツ)_/¯

That would be: (0,-3)

Yw! :D

X+20+16=90

x=54

54+20+16=90

There’s a right angle and it’s marked as 90 degrees.

Calculate<br> a) 20% of £150<br> b) 15% of 80 kg<br> c) 85% of 2 500 m

GaryK [48]

Step-by-step explanation:

$p\%=\dfrac{p}{100}$

$a)\\20\%=\dfrac{20}{100}=\dfrac{2}{10}=0.2\\\\20\%\ of\ \£150\to0.2\cdot\£150=\£30\\\\b)\\15\%=\dfrac{15}{100}=0.15\\\\15\%\ of\ 80kg\to0.15\cdot80kg=12kg\\\\c)\\85\%=\dfrac{85}{100}=0.85\\\\85\%\ of\ 2500m\to0.85\cdot2500m=2125m$
