You're solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-3Y' to each side of the equation.
7X + 3Y + -3Y = 0 + -3Y
Combine like terms:
3Y + -3Y = 0
7X + 0 = 0 + -3Y
7X = 0 + -3Y
Remove the zero:
7X = -3Y
<span>Divide each side by
'7'.
X = -0.4285714286Y
</span><span>Simplifying
X = -0.4285714286Y</span>
$5.50 * 1.8 = $9.90 (Edward)
$50 / $5.50 = 9.09 rounded to make 10 hours (Jennifer)
$50 / $9.90 = 5.05 rounded to make 6 hours (Edward)
so Jennifer needs 10 hours
Edward needs 6 hours

Answer:
180
Step-by-step explanation:
450 x 0.4 = 180
Oven tray: 600 mm by 500 mm
cake tin: 25 cm in diameter
convert mm to cm.
1 cm = 10 mm
600mm * 1cm/10mm = 60cm
500mm * 1cm/10mm = 50cm
Area of oven tray = 60cm * 50cm = 3,000 cm²
Area of cake tin = 3.14 * (25cm/2)² = 3.14 * (12.5cm)² = 3.14 * 156.25cm² = 490.625 cm²
3,000cm² ÷ 490.625cm² = 6.11 or 6 cake tins can fit on the oven tray at one time.
Answer:
The missing numbers are 5, then 35, then 49.
Step-by-step explanation:
I promise it's right :)
