Since we have the 2.1 next to the parenthesis, we need to first distribute.
2.1 * x & 2.1 * 5
2.1x + 10.5
Then we take that and add the equals seven to the problem to move onto the next step.
2.1x + 10.5 = 7
We must get the 2.1x alone, therefore subtracting the 10.5 as it will also be subtracted on the other side as well.
2.1x + 10.5 = 7
- 10.5 -10.5
2.1x = -3.5
To get the x alone, we must divide both sides by 2.1, therefore removing the 2.1 from the x.
2.1x = -3.5
/2.1 /2.1
x = 1.66666666667

Step-by-step explanation:
Answer: He would have traveled 248 miles
Explanation: This is a ratio
To find how many miles he would have traveled after 4 hours, we need to apply the information givin into a ration table
(We can put miles on the top and hours on the bottom)
217 ?
------- ------
3.5 4
Now, we can do two things:
1. cross multiply
we would take 217 times 4 (868) and divide that by 3.5 (248)
2. Divide the top and bottom by 3.5 (numerator= 62 denominator= 1)
multiply 62 by 4 to get 248
Hope this helps!
we are given
three consecutive even integers
Let's assume
first even integer is x
second even integer is x+2
third even integer is x+4
sum of the first two consecutive even integers is equal to three times the third so, we can get equation as
now, we can solve for x
so, we get
first integer is -10
second integer is -10+2=-8
third integer is -10+4=-6.................Answer
Answer:
y=-4 x=1
Step-by-step explanation:
y = 1/2x + 3
x - y = 5
x-1/2x + 3=5
-3 -3
1/2x=2
1/2 1/2
x=1
1-y=5
-1 -1
-y=4
/-1 /-1
y=-4
