1. 7r – 7 = 2r + 18
r = –5
r = 5
r = 2.2
r = 1.2
2. 2x + 12 = 18 – x
x = 3
x = 10
x = 6
x = 2
3. 8x – 3 = 15x + 18
x = –3
x = 3
x = 2.1
x = .9
4. 6y – 6 = 4y + 16
y = 2.2
y = –2.2
y = 11
y = 5
5. 3(x – 4) = 5(x + 2)
x = 11
x = –11
x = 1
x = –1
the answers are
b
d
a
c
b
1. r = 5
2. x =2
3. x = -3
4. y = 11
5. x = -11
ok so check my answers:
1. b
2. d
3. a
4. c
1.b
2.d
3.a
4.c
5.b
6.b
7.c
Thanks! 100% correct
"ur mom" Is 100% correct thanks 👍
these are all basically the same. Here's #5. It should help you on the others:
3(x-4) = 5(x-2)
expand to remove parentheses:
3x-12 = 5x+10
collect the x stuff on one side:
-2x = 22
divide by the coefficient of x: -2
x = -11
finally, check your answer!
3(-11-4) = 5(-11+2)
3(-15) = 5(-9)
-45 = -45
if you get stuck on the others, come on back and show how far you got.
“Check my answers “ is correct , thank you
thank you @check my answers
Intrustions: Solve the equation. Round to the nearest tenth if necessary.
whats the answers?
Steve anyone help
it is
b
d
a
c
b
That was easy thanks
looks hard.
thanks 'ur mom' 5/5 100%
it's always easy if you know what you're doing.
even so, there are lots of problems where the steps are easy, but you have to watch the details.
Yay for steve!
isint the first one supposed to be -5
nvm
Someone said "steve help" so nine years later after its solved im here.
1 - r = 5
2 - x = 2
3 - y = 11
4 - y = 11
5- x = - 1
HELLO I PLAY MINECRAFT I HATE FURRYS ROBLOX IS DEAD DREAM SUCKS ANDREW TATE W 2020 IS THE WORST YEAR SO IS 2021 2022
