help its pre algebra
Answer:
Burger = $15
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

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.
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.

Solve each system of equations using any method.
y = 5x +7
y = 4x - 3
Answer:
x= -10
y= -43
Step-by-step explanation:
since both of your equations equals y just plug it into each other and than make the equation: 5x+7=4x-3
and than you can just start with the variables OR numbers and then simplify
5x+7=4x-3
5x+10=4x
10= -x
x= -10
so -10 for x
plug it in to one of your 2 equations to get y
5(-10)+7= y
-50+7=y
y= -43

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.

A dance team decided to sell fruit snacks to raise money for an upcoming competition. The dancers charged $3.00 for each fruit snack they sold. In 4 days, they sold 24 packs of fruit snacks. How much money could the team earn for seven days at that same rate?
Answer:
126 dollars
Step-by-step explanation:
(i'm gonna be doing my work here, dont mind me LOL)
okay, so they sold 24 packs in 4 days. divide 24 by 4 and you get 6. multiply 6 by 3 and you get 18.
now, multiply 18 by seven and you get 126.
bam!! the dance team could earn 126$ in 7 days ^__^ hope you get an A!
Answer:
$126
Step-by-step explanation:
Let x = packs sold in 7 days
Set up a proportion. days/days = packs/packs
4/7 = 24/x
4x = 24(7) = 42 packs sold in 7 days
At $3/pack, the amount earned in 7 days = 3(42) = $126
