Answer:
A . The numbers are 6 and 7, with the smaller number as 6
B. The number is 135
Step-by-step explanation:
A. Let the numbers be a and b
adding both gives 13
a + b = 13 •••••(i)
difference between the two is 1
b - a = 1 ••••••(ii)
So we have two equations that we can solve simultaneously;
b = 1 + a; Substitute this into 1
a + 1 + a = 13
2a + 1 = 13
2a = 13-1
2a = 12
a = 12/2
a = 6
b = a + 1 = 6 + 1 = 7
The numbers are 6 and 7 while 6 is the smaller number
B.Let the number be x
Divide by 5; x/5, then subtract 2 , we get 25
x/5 - 2 = 25
x/5 = 25 + 2
x/5 = 27
x = 5 * 27
x = 135
Answer:A)33m
B)32.86m/s
Step-by-step explanation:
Using the equation of motion
V^2=U^2-2aS
Where V=final velocity of the car=0
U=initial velocity=17m/s
a=deceleration=-12m/s^2
S= distance covered by car before stopping
Substituting into the equation
0=17^2-2×12×S
0=289-24S
24S=289
S=289/24
S=12m.
The distance between the car and the deer=45-12=33m
B) Using same equation
Distance,S is now 45m,which is the distance between the car and the deer.while deceleration remains same
V^2=U^2-2aS
0=U^2-2×12×45
U^2=1080
U=√1080
U=32.86m/s
8/9x + 3
• Make 1/3 into 8/9 by multiplying it by 3/3
• add -1 and 4 to get 3
Answer:
m<A = 20
Step-by-step explanation:
6y plus 3y = 9y
180 divided by 9 = 20
20x6=120
20x2=40
120+40=160
a triangle is equal to 180 so..
180-160=20
i did 6y + 3y because that line is 180 degrees ( half of a circle)
