Answer: 20% Chance
Step-by-step explanation:
Probability of flipping heads on a coin is 50% and this wheel landing on a even number is 40% you multiply .50 and .40 and you get .20.
Answer:
the side lengths of the second triangle are 2.25mm ,3m, and 3.75mm
the work shown:
3mm 3mm × 3cm/4cm = 2.25mm
4mm 4mm × 3cm/4cm = 3mm
5mm 5mm × 3cm/4cm = 3.75mm
Answer:
30 milkshakes and 40 root beer floats
Step-by-step explanation:
Set up a system of equation (r is root beer and m is milkshake)
2.75r+6m=290
m+10=r
Substitute
2.75(m+10)+6m=290
2.75m+27.5+6m=290
8.75m=262.5
m=30
Now plug in 30 and solve for r
30+10=40
Answer:
×=17/4
Step-by-step explanation:
The equation 2x+ 4=-6x+38
First of all you collect like terms by moving the number -6x over to the left hand side which then becomes +6x as it crosses the equal to sign, likewise you move +4 over to the right hand side which then becomes -4. The equation is now 2x+6x=38-4, which when solved gives 8x=34. X is then made subject of formula by dividing both sides by 8 therefore x=34/8 which when reduced to the lowest term is 17/4

Answer:
x=2 x=-3
Step-by-step explanation:
4x2+3x=24-x
Subtract 24 from each side
4x^2 +3x -24 = 24-24 -x
4x^2 +3x -24 = -x
Add x to each side
4x^2 +3x+x -24 = -x+x
4x^2 +4x -24 = 0
Factor out a 4
4(x^2 +x -6) = 0
Divide by 4
x^2 +x -6 =0
Factor
What 2 numbers multiply to -6 and add to 1
-2*3 = -6
-2+3 =1
(x-2) (x+3) =0
Using the zero product property
x-2 =0 x+3 =0
x-2+2=0+2 x+3-3=0-3
x=2 x=-3
