Answer:
x = -1
Step-by-step explanation:
-2x + 8 = 10
-2x = 2
x = -1
I think this is how you solve this
12.5 is 25% of x
percent means parts out of 100
25%=25/100=1/4
12.5=1/4 of a number
mulitply both sides by 4
50=number
the number is 50
Answer:
C x=55
Step-by-step explanation:
the angles of a trianlge add up to 180
the unmarked angle is also 35 because of the same side length
35+35=70
180-70=110
BUT 2x=110 so x=55
P.S Can I get brainlist?
(2x-5) • (2x+5) are the expressions equivalent to 4x^2-25
