This is the point-slope formula:
We know:
x=1
y=3
m=slope=2
plug those into the formula and get
Final answer:
Answer:
x = 7
Step-by-step explanation:
Rearrange the equation to make x the subject.
Original:
7x + 3 = 52
subtract 3 from both sides
7x = 52 -3
7x = 49
Divide both sides by 7
x = 49/7
x = 7
23 and 29 are both prime numbers so the only common factor they would have would be 1.
Find the perimeter of a picture first.
width = 7 1/2 = 15/2 in
length = 8 in
perimeter = 2(width) + 2(length)
p = 2(15/2) + 2(8)
p = 15 + 16
p = 31 in
next, find the perimeter of border.
p = 4(1 1/4)
p = 4(5/4)
p = 5 in
perimeter of picture with border = 31 + 5 = 36 in
Answer: 24
Step-by-step explanation:
Given :
b - 2a - c
a = - 7
b = 3
c = - 7
Substituting the values into the expression , we have
3 - 2 ( - 7 ) - ( - 7 )
⇒ 3 + 14 + 7
= 24
