Answer:
the width is 46 and the length is 99
Step-by-step explanation:
perimeter = 290 yards
length =2w+7
width =w
perimeter = 2w + 2l =290
2w+ 2(2w+7) =290
2w+4w+14= 290
6w = 276
w= 46
Answer: A. Suzy made an error going from Step 1 to Step 2.
Step-by-step explanation: Following the order of operations (PEMDAS), we know that exponents are dealt with before multiplication. Suzy used the distributive property of multiplication going from step 1 to step 2, rather than working with the exponent.
Answer: (8, -4)
Step-by-step explanation:
<span>"A TV is on sale at 30% off for $420"
What was the original price of the TV?
</span>
Well if you start to calculate first off you are sooner or later going to figure out that in order for it to be 420 the answer has to be bigger than 1,000. If you get to 1,200 and calculate 30 percent off of it it the answer is 360 so a ballpark quesstiminate would be to go two more hundredths up. Therefore 30 percent of 1,400 is 420
Answer:
x = 18
y = 54
Step-by-step explanation:
A straight line equals 180 degrees.
Since Lines CD and AB are straight, we can deduce that the angle 3x = 2x + angle AN.
Because there is a right angle, we can subtract 90 -72 = 18.
18 + 2x = 3x
18 = x
A straight line equals 180 degrees. Once we figure out that x = 18, we can figure out y by plugging in x and then subtracting your answer from 180 degrees.
