Determine the correct value of 3x + 2 when x = 5. Show your work
Answer:
17
Step-by-step explanation:
3 multiply by 5 (which is x) = 15+2
The value of function 3x + 2 at x = 5 will be 17.
What is substitution method?
To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The function is,
⇒ 3x + 2
And, The value of x = 5
Now,
The value of the function 3x + 2 at x = 5 is find as;
The function is,
⇒ 3x + 2
Substitute x = 5 in above equation as;
⇒ 3x + 2
⇒ 3 × 5 + 2
⇒ 15 + 2
⇒ 17
Thus, The value of function 3x + 2 at x = 5 will be 17.

Write 0.6% as a fraction in simplest form.
Answer:
[tex]\frac{3}{5}[/tex]
Answer:
3/500
Step-by-step explanation:
Percent means
per hundred.
So we have the following.
0.6%=0.6 per hundred = 0.6/100
We next need to rewrite 0.6/100 so that is doesn't have a decimal in the numerator.
To do this, we multiply it by 10/10, which equals 1.
0.6/100 = 0.6/100 x 10/10 = 6/1000
(Note that we do not try to cancel when doing the multiplication.)
Our answer must be written in simplest form.
This fraction has a denominator of 1000.
So we can simplify it by focusing only on the factors 2 and 5.
In this case, we can divide both the numerator and denominator be 2.
6/1000 = 6 ÷ 2/1000 ÷ 2 = 3/500
We cannot use 2 or 5 to simplify further. So 3/500 is in simplest form.
So the answer is 3/500.

A circular garden has a circumference of 63 yards. Lars Is digging a straight line along a diameter of the garden at a rate of 5 yards per hour. How many hours will it take him to dig across the garden? Use 3.14 for 1 and round the diameter to the nearest whole number, if necessary. It will take Lars about hours to dig across the garden.
PLZ answer need by 10:40
Answer:
4 hours
Step-by-step explanation:
f the circumference of the circular garden =63 yards
Circumference of a Circle =2πr=πd (d=diameter)
Therefore:
πd= 63
diameter of the circular garden =63/3.14=20 yards
If he digs at a rate of 5 yards per hour, the time required to dig across the garden will be:
20 yards/5 yard per hours = 4 hours
It will take him 4 hours to dig across the circular garden.
A car rental agency advertised renting. a car for $24.95 per day and $0.27 per mile. If Brad rents this car for 4 days, how many whole miles can he drive on a $200 budget?
Answer:
Around 370 when rounded
Step-by-step explanation:
ok so we know that for one day rental cost 24.95 and 0.27 per mile.
Brad has a budget of 200 and wants to rent a car for 4 days and wants to know how many miles he can drive with his budget.
First off you have to mulitply 24.95(which is how much the rental cost per day) by 4. 24.95 x 4=99.8 so out of his 200 dollars he now has 100 budget for miles.
Next we are going to divide the 100 dollars left out of the budget by the cost per mile which is 0.27. 100/0.27=370 when rounded.

Hot Dog = $10
Step-by-step explanation:
b=35-2h
4(b-2h)+6h=120
4(35-2h)+6h=120
140-8h+6h=120
140-2h=120
-2h=120-140
-2h=-20
h=10
b=35-2h = 35-20 = 15
Find the slope of a line with this information, "−12; (4,−5)". Write your answer in slope intercept form.
Answer:
y = -12x - 43
Step-by-step explanation:
"slope-intercept form" looks like y = mx + b.
We are given m = -12 and a point on the line which is (4, -5).
Substituting 4 for x, -5 for y and -12 for m, we get:
-5 = -12(4) + b. Then b = -43, and the desired equation is y = -12x - 43.
