Sienna has $8 and is saving $3 per week. Jacob has $6 and is saving $4 per week. Which model represents the equation that can determine when Sienna will have the same amount of money as Jacob?
8 Negative x tiles and 3 positive 1 tiles = 6 positive x tiles and 4 positive 1 tiles
8 x tiles and 3 positive 1 tiles = 6 x tiles and 4 positive 1 tiles
3 x tiles and 8 positive 1 tiles = 4 x tiles and 6 positive 1 tiles
3 negative x tiles and 8 positive 1 tiles = 4 x tiles and 6 positive 1 tiles
Answers
Answer:
B
Step-by-step explanation:
From the given information:
Sienna has $8 denotes the unit blocks of x tiles. So, she saved $3 per week.
This implies that:
8x + 3(1) = 8x + 3
Also,
If Jacob as well had $6 which implies 6x unit block of tiles while he saved $4;
i.e.
6(x) + 4(1) = 6x + 4
So;
the model that can determine when Sienna will have the same amount as Jacob is:
8x + 3 = 6x + 4

Let's solve your equation step-by-step.
4x+3=31
Step 1: Subtract 3 from both sides.
4x+3−3=31−3
4x=28
Step 2: Divide both sides by 4.
4x/4=28/4
x=7
FOR Y:
Step 1: Simplify both sides of the equation.
(3)(7)+6y=30
21+6y=30
6y+21=30
Step 2: Subtract 21 from both sides.
6y+21−21=30−21
6y=9
Step 3: Divide both sides by 6.
6y/6=9/6
y=3/2
