Convert percentages to units.
100% - 20% = 80% = 0.8
100% - 25% = 75% = 0.75
Then multiply those together:
0.8*0.75=0.6=60%
100% - 60% = 40%. That's the overall price percentage reduction.
P.S. You can convert percentages to units by diving % by 100 for example 100% divided by 100 is equal to 1.
And vice versa aka multiply units by 100 and you get %, for example 0.8 times 100 is 80%
4a + 3 = 15

Answer:
m = 13
Step-by-step explanation:
Given
m - 5 = 8 ( isolate m by adding 5 to both sides of the equation )
m = 8 + 5 = 13
X = 16y^2 + 1
x - 1 = 16y^2
(x - 1)/16 = y^ 2
( (x-1) / 16 ) ^1/2 = y
( (x-1) ^ 1/2 ) / 4 = y
X/5 - 11 = -13
x/5 - 11 (+11) = -13 (+11)
x/5 = -2
x/5 (5) = -2(5)
x = -10
-10 is your number
hope this helps
