<span>In
4 weeks, it dropped 3 feet in total.
The unit rate of this is 3 feet / 4 weeks
If we simplify this into days, this will be the solutions
=> 4 weeks has (4 * 7) 28 days in total, so we need to divide 3 feet by 28
days to get the simplified unit rate.
=> 3 feet / 28 days
=> .107 feet / day.
So the water drops .107 feet per day and in 4 weeks the total of 3 feet.</span>
A) JL and JK
Because you must always start from top to bottom and left to right.
Answer:
Step-by-step explanation:
Given are two triangles ABC and XYZ.
We have AB = XY = 25 cm, AC = YZ = 29 cm
and also angle A = angle X = 36 degrees
Thus we find that corresponding congruent sides are
AB and AC with angles A and X
To map ABC onto xyz,
Vertex B to Y, side AB to side XY with AC coinciding with XZ
Now all vertices x,y,z will perfectly match with transformed ABC
Answer: 21
Step-by-step explanation:
This means we can substitute x=5 into f(x), so f(5)=6+3(5)=21.
Answer:
12.)-5
13.)-16
14)-20
15)6
16)-13
17)1
18)-13
19)15
20)-10
Step-by-step explanation:
12.)-x=2+3
x=5/-1
so,x=-5
13.)-4=(-2×8+x)/8
-4×8=-16+x
-32+16=x
so,x=-16
14)(7×4+m)/4=2
28+m=8
so,m=-20
15)4n=34-10
n=24/4
so,n=6
16)-2a=22+4
a=26/-2
so,a=-13
17)a+3=2×2
a=4-3
so,a=1
18)-133+3=10x
-130=10x
so,x=-13
19)4+1=v/3
5*3=v
so,v=15
20)1=3+r/5
now,
Take LCM,
We get,
1=(3*5+r*1)/5
now,
by moving 5 into LHS
We get,
1*5=15+r
5=15+r
by moving 15 into left hand side,
We get ,
5-15=r
so,r=-10 because when we subtract smaller from bigger we have to take the sign of bigger.
