can someone please answer this math problem for me, please answer all of them if you can ​

Answer:

(50, 20)

Step-by-step explanation:

y = -2x + 120

x + (-2x+120) = 70

  -x = -50

x = 50

 y = -2x+120

 y = -2(50)+120 = 20

{x,y} = {50,20}  

Answer:

8

Step-by-step explanation:

So. Let's plug in 2 for y. 7(2)-3(2). Before we subtract, let's multiply first. 7 times 2 is 14 and 3 times 2 is 6. So now the equation looks like this: 14-6. From here, you do regular subtraction to get 8. Hope this helps!

Answer:

x = -4 and y = 1

Step-by-step explanation:

-x + y = 5

+ x - 5y = -9 <— let’s eliminate x

————————————-

-4y = -4

y = 1

x - 5y = -9 <— substitute for y

x - 5(1) = -9

x - 5 = -9

+5 = +5

x = -4

Answer:

It can not be determined from the information given because the calorie sources are not independent.

Step-by-step explanation:

Explained in answer above.

There is no enough information to calculate the standard deviation of T.

Check below on how to determine the standard deviation

The standard deviation of a dataset is how much the data elements of the dataset are far from the mean or average value of the dataset

The given parameters are the mean and the standard deviations of calories from fat, protein, and carbohydrates

These values are not enough to determine the standard deviation of T

Hence, there is no enough information to calculate the required standard deviation

Answer: Hi, the answer is 9/4 or C!

Step-by-step explanation:

You would take 2/7 and multiply both the top and bottom by 2 to make it 4/14, the. youd flip 4/14 into 14/4, then multiply the top numbers (9 and 14 by eachother to get 126) then multiply the bottom numbers ( 14 and 4 to get 56) and simplify the new fraction (126/56) to get 9/4!

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

Answer:

The area of the triangle is 24 inches.

Step-by-step explanation:

First you multiply 8 by 6.

8 * 6 = 48

Next you divide by 2 because a triangle is half of a square.

48 ÷ 2 = 24

So, the answer is 24.

Hope this helps! :)

The area of triangle with base 6 inches and height 8 inches is 24in² .

Given, Right angled triangle .

Area of triangle = [tex]\frac{1}{2} \times b \times h[/tex]

Here,

b = base of triangle

h = height of triangle

Substitute the values,

Area of triangle = [tex]\frac{1}{2} \times b \times h[/tex]

[tex]= \frac{1}{2} \times 6 \times 8\\ = 3 \times 8\\= 24in^2[/tex]

Answer:

[tex]\sqrt{49}[/tex]=7

The value of the square root of the number 49 is 7.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs. An nth root of a number x is a number r that when raised to the power n yields x.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the number is 49 and the square of the number is calculated as,

E = √49

E = √ ( 7 x 7 )

Answer:

7x = 35cm ; 2x = 10cm

Step-by-step explanation:

7x and 2x are the lengths

7x+2x=45

Then you take 7 + 2 = 9

so is gonna be 9x = 45

then you divide both side with 9

so is gonna be x = 5

Then you take 5 multiply 7 : 2

so 7 x 5 = 35cm

2 x 5 = 10cm

Answer:

$1.68

Step-by-step explanation:

The total cost is $16.07 and there was 2 things bought- the oranges and the juice bottles. to make it easier to find the cost of the juice bottles, we'll subtract the cost of the oranges (2.63) from the total (16.07), which gives us 13.44. this number represents the total cost of only the bottles. To find out the cost if each individual bottle, you need to divide the total (13.44) by the number of bottles (8). This gives us 1.68, so the cost of each bottel is $1.68

Answer: 1.68

Step-by-step explanation: It depends how your teacher thought how to solve this but the easiest way would be: 16.07 - 2.63 = 13.44 than 13.44 divided by 8= 1.68.
