Answer:
Hope this helps :] look at the picture
Step-by-step explanation:
Time spent 4 hours (240 minutes) from point A (state park) to point B (beach)
Distance from A to B is 240 mi.
240mi/4hours = 60 miles/hour
Basically what this is, is:
100% = 100/100
Basically, to get the fraction, you just set the denominator as 100 and move the percentage up. You can then multiply by as many powers of 10 as needed or simplify the fraction as many times as needed.
Ex:
78.7% = ?/100
Just put 78.7 into that question mark spot to get:
78.7/100 = 78.7%
Now, you multiply the whole thing by 10/10:
787/1000
So that's your fraction.
29% = ?/100
Then it would be,
29/100.
55.8%: 558/1000, you could simplify that by dividing both the numerator and denominator by 2, and you would get 279/500.
28.2%: 282/1000, simplify that: 141/500
82%: 82/100, 41/50
74%: 74/100, 37/50
91.8%: 918/1000, 459/500
72%: 72/100, 18/25
129%: 129/100
15.8%: 158/1000, 79/500
24.3%: 243/1000
93%: 93/100
The approximate solution of this system of equations is
(x,y)=(-0.25,1.25)
<h3>What is an equation?</h3>
Equation is defined as the state of being equal and is often shown as a math expression with equal values on either side, or refers to a problem where many things need to be taken into account.
Given that,
y = |x − 1| and y = 3x+2
y = |x − 1|
= (x-1) , for (x-1)>0 or x>1
and
y = -(x-1) , for(x-1)<0 or x<1
y = -x+1
Now, For x>1
y = x-1 ......(1)
y = 3x+2 ......(2)
Solving for x by equaliting's method:
3x+2 = x-1
→ 3x-x = -1-2
→ 2x = -3
→ x = -3/2
→ x = -1.5 which is <1.
For x<1
y = -x+1 ......(1)
y = 3x+2 ......(2)
Solving for x by equaliting's method:
3x+2 = -x+1
→ 3x+x = 1-2
→ 4x = -1
→ x = -1/4
→ x= -0.25 which is <1.
substitute the value of x = -0.25 in equation 1 for x<1.
y = -x+1
= -(-0.25)+1
y = 1.25
Hence, The approximate solution of this system of equations is
(x,y)=(-1/4,5/4)=(-0.25,1.25).

Here is your answer:
7. 3×1=3
7×1=7
2. 5×1=5
7×1=7
=5 -2/7
Step one: write the equation
Step two: find the common denommarator (which is 7)
Step three: subtract 3-5= which equals to negative 2
Step four: subtract the whole numbers ( 7 and 2) which gives you five
Your answer is...
5 -2/7
