Answer:
x - 29 so, 18 is smaller than 45 and 48 is bigger than 45
Answer:
Kim is 24 years older than Tom Kim and Tom are twins. These two statements are not compatible, unless the mother of Kim and Tom was in labor for 24 years LOL
Second statement
Savannah and Sebastian are the same age (twins)
X being Ryan's age the correct answer is 24+x = 5x
D is the correct answer
To solve 24+x= 5x
Subtract x from each side
24= 4x
Divide each side by 4
6= x
Savannah is 30 Sebastian is 30 Ryan is 6
Step-by-step explanation:
Answer:
27
Step-by-step explanation:
15x-31 = 9x+11
6x-31 = 11
6x = 42
x = 7
15x -31 + 9x + 11 + s = 180
15(7) -31 + 9(7) + 11 + s = 180
105 - 31 + 63 + 11 + s = 180
153 + s = 180
s = 27
Answer: 1045 cm of red ribbon and 1045 cm of yellow ribbon
<u>Step-by-step explanation:</u>
Let R represent the amount red ribbon and Y represent the amouont of yellow ribbon.
- bought the same lengths of red and yellow: R = Y
- after used 286 of red, yellow is 5 times the remaining red; 5(R - 836) = Y
Use substitution method to solve:
5(R - 836) = R
5R - 4180 = R <em>distributed 5 on the left side</em>
4R - 4180 = 0 <em>subtracted R from both sides</em>
4R = 4180 <em>added 4180 to both sides</em>
R = 1045 <em>divided both sides by 4</em>
