Answer:
6
Step-by-step explanation:
6+6=12
12x6=72
y=2x-3
y=x+2 system of equations
Answer:
x = 5
y = 7
Step-by-step explanation:
Since they are both equal to y, we can set them equal to each other.
2x - 3 = x + 2
Combine like terms and isolate the x.
x = 5
Plug in the x to either equation to get the value of y.
y = (5) + 2
y = 7

Carmen rents roller skates for $5 plus $2 for every hour she uses them. Define the variable and write an expression for the total cost to rent roller skates. Then find the total cost if Carmen rest them for 4 hours.
Given:
Carmen rents roller skates for $5 plus $2 for every hour she uses them.
To find:
The expression for the total cost to rent roller skates. Then find the total cost if Carmen rest them for 4 hours.
Solution:
We have,
Fixed rent = $5
Additional rent = $2 per hour.
Let x be the number of hours.
So, additional rent is $2x.
Now,
Total rent = Fixed rend + Additional rent
= $(5+2x)
So, the expression for total cost is $(5+2x).
Carmen rent them for 4 hours. So, x=4 and the total cost is
[tex]\text{Total cost}=5+2(4)[/tex]
[tex]\text{Total cost}=5+8[/tex]
[tex]\text{Total cost}=13[/tex]
Therefore, the total cost of 4 hours is $13.

What is the value of x?
Enter your answer in the box.
x =
Answer:
X = 62°
Step-by-step explanation:
Since opposite or vertical angles are equivalent, you can form the equation that 28 + x = 90 (In case you didn't know, right angles are always 90°). Subtract 28 from both sides to find the value of x and you'll get x = 90 - 28 or x = 62°.

If 8 engines consume 12000 kgs. of coal when each running 10
hours per day, how much coal is required for 7 engines out
which 5 are running 12 hours a day and the rest 6 hours a day?
Answer:
11200 for 7 engines for a total of 80 hours
Step-by-step explanation:
You have 8 engines burning 12000 .for 10 hours.
Divide 10 hours into 12000=1200 PER hour.
1200 ÷8 engines = 140 per hour per engine.
140 × # of hours (12)=1680 for 12 hours per engine.
# of engines × 1680 for 12 hour/per engine
5×1680 = 8400 of fuel for 12 hours/5 engine
Then you have 2 that runs 10 hours
2 × 140 per hour per engine =280 × 10 =2800 for 2 engines for 10 hours
8400. + 2800= 11200 of fuel for 6 engines

Learning task 1: find the value of the expression given the value of the variables 3x + 5 x = 2 5xy + x - 4 , x = -3 and y = 5
Step-by-step explanation:
3x+5x=25xy+x-4
8x=25xy+x-4
8(-3)=25(-3)(5)+(-3-4)
-24=25(-15)+(-7)
-24= -375-7
-24= -382
if the question is right that you asked, i mean the = sign then the solution is will be come like this but if there is no = sign then you can get the solution by subtracting -24-382= -406
Cuantos ml debe aplicar de gentamicina para administrar una dosis de 50 mg si la presentacion es de 80 mg/3ml
Answer:
1.875ml
Step-by-step explanation:
De la pregunta anterior, podemos decir que:
80 mg = 3 ml
50 mg = x ml
Cruzamos multiplicar
80 mg × xml = 50 mg × 3ml
xml = 50 mg × 3 ml / 80 mg
xml = 1.875ml
Por tanto, se deben aplicar 1.875ml de gentamicina para administrar una dosis de 50 mg.

Step-by-step explanation:
it is 3/5. Than 6/10 is equal to 3/5. Than 9/15 is equal to 3/5.
Answer: True
Step-by-step explanation:
That is true because let's take the first point for example.
3 cups of almonds for 5 cups of oats.
3/5 of 5 is 3
So that's correct.
If you still aren't sure you should try that with a different point. Hmm how about :
9 cups of almonds for 15 cups of oats
3/5 of 15 = 45/5 = 9
That's correct as well.

During the summer isabelle sells corn at her familys produce stand every morning she starts with 250 ears of corn on saterday isabelle sells 150 of the 250 ears of corn she wants to know what percent of the corn she sold what percent of the 250 ears of corn did isabelle sell complete the statement
Answer:
Isabelle sold 60% of the corn on Saturday
Step-by-step explanation:
In order to calculate the percentage of the corn that Isabelle sold we first need to divide the number of corn that she sold by the total number of corn that she had initially.
150 / 250 = 0.6
Now we simply need to multiply this decimal value by 100. This will give us the percentage of corn sold as a percentage value.
0.60 * 100 = 60%
Therefore, we can see that Isabelle sold 60% of the corn on Saturday
