Step-by-step explanation:

100% = X

50% = 100%/2 = X/2

X decreased by 50 means X - 50% = X - X/2 = X/2

now,

100% = X/2

50% = 100%/2 = X/2 / 2 = X/(2×2) = X/4

increasing the previous result by 50% means

X/2 + 50% = X/2 + X/4 = 2X/4 + X/4 = 3X/4

so, comparing this to the original X (= 4X/4), we are X/4 short.

Solve for c.<br> a(c+b) = d.

kipiarov [429]

Answer:

Step-by-step explanation:

Hello,

we assume that a is different from 0 otherwise there is not much we can say on c and then we can write

a(c+b)=d

<=> ac+ab=d

<=> ac = d - ab

<=> $c = \dfrac{d-ab}{a} =\dfrac{d}{a}-b$

Hope this helps

Which measurements could not represent the side lengths of a right triangle?

victus00 [196]

Answer: C

Step-by-step explanation: a^2 + b^2 = c^2

A. 6^2 + 8^2 = 10^2

B. 12^2 + 35^2 = 37^2

C. 4^2 + 6^2 does not equal 10^2.....(16 + 36 = 52 10^2 = 100)

D. 10^2 + 24^2 = 26^2
