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
W=20 feet = 55% thus 20/55*100= L=36.36 Feet Fromula A=w*l
A=727.2 Feet²
Answer:
Fraction of fence = 2/3 which is approximately 0.67
Explanation:
We know that he finishes 1/3 of the fence in 1/2 an hour. To know the fraction he can finish in one hour, we will simply use cross multiplication as follows:
1/3 of the fence ...................> 1/2 an hour
?? of the fence ....................> 1 hour
Fraction of the fence = (1/3 * 1) / (1/2)
Fraction of fence = 2/3 which is approximately 0.67
Hope this helps :)
The answer is D. If you plug in (-2,8) into both equations you’ll get the same outcome. Which is 6 , -10.
