Speed in miles per hour is calculated as:
distance (in miles) ÷ time (in hours)
So we have:
(3/4) ÷ (3/10) = (3×10)/(4×3) = 30/12 = 15/6 = 5/2 = 2.5
So his speed is 2.5 mph (miles per hour).
3x+3 + 10x-4 +90 (because complementary angle add up to 90)
13x-1+90 (add 1)
13x/13=91 (divide 13 on both sides)
x=7
now you fill in 7 for x
m<K=24 and m<L=66
hope i helped
Answer:
Step-by-step explanation:
20x - 44z = 84
528x + 44z = 1012
548x = 1096
x= 2
48(2) + 4z = 92
96 + 4z = 92
4z = -4
z = -1
(2, -1)
Answer:
Step-by-step explanation:
let polynomial P(x)=ax³+bx²+cx+d
-3=-a+b-c+d
-2=d
-1=a+b+c+d
-1=a+b+c-2
a+b+c=1
-3=-a+b-c-2
a-b+c=1
a+b+c-(a-b+c)=1-1=0
2b=0
b=0
so a+c=1
6=8a+4b+2c+d
6=8a+4b+2c-2
8a+4b+2c=8
4a+2b+c=4
or 4a+0+c=4
4a+c=4
a+c=1
subtract
3a=3
a=1
1+c=1
c=0
reqd .P(x)=1x³-2=x³-2
