Answer:
n = 36
Step-by-step explanation:
4 : 5 = n : 45
It can be also written as :-
[tex]\frac{4}{5} = \frac{n}{45}[/tex]
Multiplying both the sides by 45 ,
[tex]=> \frac{4}{5} \times 45 = \frac{n}{45} \times 45[/tex]
[tex]=> n = 4 \times 9 = 36[/tex]
(2x+4)(x-2)
please help
Answer:
2x squared - 8
Step-by-step explanation:
For this kind of equation, we use the distributive property
So in the image below I used a box method (that's how I learned it in school)
So since -4x and 4x cancel each other out, or amount to 0, we don't put anything for those. So the equation left is 2x squared - 8

Savannah is 9 years older thanDevante. The sum of their ages is 53. How old are Savannah and Devante?
(A) First write an equation you can use to answer this question. Use x as your variable.
The equation is _______
Answer: Devante is _______
and Savannah is ______
Answer:
Devante is 23 and Savannah is 32.
Step-by-step explanation:
We can set up a system of equations.
s - savannah's age
d - devante's age
s = d + 9
s + d = 53
Now we can substitute (d + 9) for s in the second equation.
(d + 9) + d = 53
2d + 9 = 53
2d = 46
d = 23
To find Savannah's age, we just add 9 to Devante's age. (plugging in 23 for d)
23 + 9 = 32
s = 32
Student Council held a bake sale to raise money for the local food pantry. They sold a total of 40 items which included pies and cakes. Pies were $10 each and cakes were $8 each. They raised $356. How many pies and how many cakes did they sell?
Answer: 18 pies, 22 cakes
Step-by-step explanation:
Let the number of pies sold be represented by p.
Let the number of cakes be represented by c.
The information in the question can then be represented in an equation as:
p + c = 40 ........ i
10p + 8c = 356 ....... ii
Multiply equation i by 10
Multiply equation ii by 1
10p + 10c = 400 ....... iii
10p + 8c = 356 ....... iv
Subtract iv from iii
2c = 44
c = 44/2
c = 22
22 cakes were sold
Since 40 items were sold, the number of pies sold will be:
= 40 - 22
= 18 pies

what is the prime factor of 350
Answer:
If we put all of it together we have the factors :2 x 5 x 5 x 7 = 350.
Step-by-step explanation:
It can also be written in exponential form as 21 x 52 x 71.
Hope this is helpful .
Answer:
Step-by-step explanation:
draw the prime factor tree of 350
you can choose any 2 numbers that equals 350, then continue in that way by choosing any 2 numbers that equals the number that's on top of the 2 other numbers when multiplying, except 1×number, because it won't help you to get the prime factors of a specific number, unless it's a prime number so you don't need to multiply by any number
350
35 10
5 7 2 5
350=2×5×5×7
