Answer:
2/5
Step-by-step explanation:
Let x = numerator
3 + x = denominator
the numerator and denominator are increased by 1 , the fraction becomes
cross multiply
2(x + 1 ) = 4 + x
2x + 2 = 4 + x
combine like terms
2x - x = 4 - 2
x = 2 = numerator
denominator = 2 + 3 = 5
2/5 fraction
Answer:
x=3
Step-by-step explanation:
∠DBC+∠VBC is 180° since it is a straight line, ∠VBC=20x+5
The sum of all angles in a triangle is 180°, 9x-2 + 40° +∠DBC=180°
To find x, you can find ∠DBC first. *Don't forget BRACKETS
∠DBC=180-(20x+5)
∠DBC=180-(9x-2 + 40°)
Now equal the equations to each other to find x.
180-(20x+5)=180-(40+9x-2)
180-20x-5=180-40-9x+2
175-20x=142-9x
175-142=20x-9x
33=11x
x=33/11
∴x=3
Answer:
-2
Step-by-step explanation:
f(-6)=x^2+8x+10
f=(-6)^2+8(-6)+10
f=36-48+10
f(-6)=-2
Answer:
x=7
because distributive property and addition and subtraction
Answer:
True
Step-by-step explanation:
The whole point of units conversion is to take a value expressed in one set of units (parts per hour) and translate it to a different set of units (parts per week). The rate does not have to involve time.
The statement is TRUE.
