The perimeter of a rectangle is twice the sum of its side lengths.
P=2(L+W), we are told that L=3W and P=176 so
2(3W+W)=176
2(4W)=176
8W=176
W=22 ft, since L=3W
L=66 ft
So the yard is 22 feet wide and 66 feet long.
1. For the first question, asking to write an equation for how much more Max needs to save up, It would simply be 95.00 + n = 150.00.
This is because he has $95 and needs $n more to get to the final amount of $150.
2. For the second question, asking which number being substituted for n makes the equation true, isolate n in the equation to find what it equals. To do this, subtract 95 from both sides.
95 + n - 95 = n < This isolates the variable.
150 - 95 = 55
This means n = 55 (fifty five)
3. The inequality is a bit more complicated since it says less than $5 per week. The way I'd do it would get some kind of answer but because I haven't done inequalities like this in a while, I unfortunately can't help you with this part. I can say, however, that it more than likely has something to do with being between two values, but I'm not sure. Sorry for the inconvenience.
<u>Answer:</u>
x = 6.00001
<u>Step-by-step explanation:</u>
We are given the following log problem to solve for x:
log(x) + log(3) = log(18)
log(x) + 0.477121 = 1.255273
Adding -0.477121 to both the sides to get:
log(x) + 0.477121 + (−0.477121) = 1.255273 + (−0.477121)
log(x) + 0 = 0.778152
Dividing both the sides by 1 to get:
log(x) + 0/1 = 0.778152/1
log(x) = 0.778152
Solving the logarithm to get:
log(x) = 0.778152
10log(x) = 100.778152
x = 6.00001
A) is 28 response are recorded
B) there was only 24 students polled
C) A possible explanation for having more responses recorded than students polled is that they some may have played more than one sport.
Answer:
D. The subtraction property of equality was not applied to solve this equation.
Step-by-step explanation:
<u>Step 1</u>: Given
<u>Step 2</u>: Addition Property of Equality
(add 7 to both sides)
<u>Step 3</u>: Simplify
<u>Step 4</u>: Multiplication Property of Equality
(multiply both sides by 2)
<u>Step 5</u>: Simplify
