A/B=B/A
A and B can be any number. They just have to be the same number. Because If you divide a number by its self you get 1
EX: 10/10 =1= 10/10
Answer:
is it 11 divided by 6 divided by six or 6/6 because that is equal to one.
Step-by-step explanation:
Answer:
Pamela = 30
Jiri = 40
Step-by-step explanation:
Two equations needed:
J-10 = P
P+J = 70
Plug and solve:
(J-10) + J = 70
2J - 10 =70
2J = 80
J = 40
40 - 10 = P
P=30
First solve for one variable
solve for a in second eqatn
minus 3x both sides
a=17-3x
sub 17-3x for a in first equaiton
2(17-3x)+2x=18
34-6x+2x=18
34-4x=18
minus 34 both sides
-4x=-16
divide both sides by -4
x=4
sub back
a=17-3x
a=17-3(4)
a=17-12
a=5
a is 5
x=4
WORK SECTION (without thoughts)
2a+2x=18 to a+x=9
a+3x=17
a=17-3x
(17-3x)+x=9
17-2x=9
-2x=-8
x=4
a=17-3(4)
a=17-12
a=5
x=4
a=5
