You need to form an algebraic equation. 4.5+h=7.3 therefore h= 7.3 - 4.5 when you take 4.5 to the other side it becomes negative therefore the answer is 2.8.
Answer:
4=4x
Step-by-step explanation:
the formula y=mx+b
corresponds to y=slope+y intercept
all proportional relationships start on the origin so the y-intercept is always 0
the fact that the equation y = 4x doesn't have an intercept shows its proportional this can go with any similar equation like y = 4.5x
100% of anything is the whole thing.
101% of it is more than the whole thing.
150% of it is the whole thing plus half of another one.
Total cost is 220 dollars. This is because 3 times 60 is 180 and plus membership fee of 40 dollars is 220 dollars.
Answer:
x = 6
Step-by-step explanation:
<em>This can be written as a ratio</em>
7 : 2
21 : x
<em>If you times one side by 3, you have to multiply the other side by three too:</em>
2 × 3 = 6
∴ x = 6 when y = 21
