Answer:
Step-by-step explanation:
During a sale at the market, steaks sold for $2 and watermelons sold for $1.50. Declan spent $10 and bought a total of 6 steaks and watermelons. How many of each did he buy?
Let us represent
Steaks = x
Water melons = y
Our system of equations is given as:
x + y = 6.. Equation 1
x = 6 - y
During a sale at the market, steaks sold for $2 and watermelons sold for $1.50.
$2× x + 1.5 × y = $10
2x + 1.5y = 10... Equation 2
Substitute
2(6 - y) + 1.5y = 10
12 - 2y + 1.5y = 10
12 - 10 = 2y - 1.5y
2 = 0.5y
y = 2/0.5
y = 4
Answer:
30 meters away
Step-by-step explanation:
each second is equal to 5 meters, hence meters per second
Undefined
Rise/ run = slope
1 rise / 0 run = 1/0 which is undefined
Your answer would be 1, or 72+25.
What is happening in this case is a negative number is being subtracted from a positive. This means you are taking away a negative. The two negatives cancel each other out, and then it becomes you are adding a positive.
Another way I like to think about this is the two minus symbols combine together to form a plus sign.
Hope this helped!
