Step-by-step explanation:
To make the coefficient of x equal we can multiply both sides of (1) by 2. the answer is B
Answer:
20.3 units
Step-by-step explanation:
Write and solve an equation involving ratios:
5 units 15.7 units
------------- = ----------------
9 units C
Cross-multiplying, we get 5C = 9(15.7), with C measured in "units."
Then 5C = 141.3, so that C = 141.3 units / 5 = 20.3 units.
Answer:
width = 5cm
length = 10cm
Step-by-step explanation:
1. the ratio is 1:5 so 50 metres in real life is 10 centimetres on paper so length = 10 cm
2. 25 metres in real life is 5 centimetres on paper so width = 5 cm
Equation for this line is y = -2x + (-4)
<u>Step-by-step explanation:</u>
Step 1:
Slope intercept equation for a line is of the form y= mx + b, where m is the slope and b is the y-intercept.
Step 2:
Calculate slope of the given line.
⇒ m = (y2 - y1)/(x2 - x1) = (2 - (-2))/(-3 - (-1)
⇒ m = 4/-2 = -2
Step 3:
Find y-intercept
⇒ b = - 4
Step 4:
Substitute values to get equation
⇒ y = -x -4 or y = - (x + 4)
Answer: $37.50
Step-by-step explanation: Assuming you mean 25% off and not 25% of the original price, first convert 25% to a decimal by dividing by 100. 25%/100=0.25. Multiply the price by 0.25. 50*0.25=12.5. Subtract the discount from the original price. 50-12.5=37.5.
