Simultaneous Equations
3x + y = 4
5x - y = 22
The signs of the matching values aren't the same so we add the rest of the equations.
8x = 26
Divide both sides by 8 to get x = 3.25
Now substitute back into the first equation.
(3 x 3.25) + y = 4
9.75 + y = 4
Subtract 9.75 from both sides
y = -5.75
Answer:
222- 50+1=0? 225 - 50 = 175 175+1 = 176 176+0 = 176
Answer:
Step-by-step explanation:
Dan bought 8 shirts and 3 pants. This means that the ratio representing the number of shirts to the number of pants that Dan bought is 8/3 = 2.67
Devonte bought 12 shirts and 5 pants. This means that the ratio representing the number of shirts to the number of pants that Devonte bought is 12/5 = 2.4
Therefore, they are not equivalent ratios because the relationship is not exactly the same.
48/70 = 24/35
24/35 = 0.6857
= 68.57%
I can’t figure out if I need a graph or a picture could you post the picture 12333
