3x + 4y divided by 2 when x=7 and y=10

Answers

Answer 1

Answer: For this question you can put 7 for x and 10 for y.
Then solve 3x + 4y:
3(7) + 4(10) = 21 + 40 = 61
so now you can divide it by 2:
61/2 = 30.5 :)))
I hope this is helpful
have a nice day

You can find the volume of a rectangular solid using the formula Volume=Length.width.height, or V=lwh. Find the volume of the rectangle solid pictured here! 5,3,7

Answers

The volume of the rectangular solid is 105 cubic units. A rectangular solid is a three-dimensional shape with six rectangular faces.

To calculate its volume, we use the formula:

Volume (V) = Length (l) × Width (w) × Height (h)

To find the volume of the rectangular solid (rectangular prism) with dimensions of length = 5 units, width = 3 units, and height = 7 units, we can use the formula:

Volume (V) = Length (l) * Width (w) * Height (h)

V = 5 * 3 * 7

V = 105 cubic units

The units are multiplied together since volume is a measure of three dimensions (length × width × height). In this case, the units are given in "units," so the final volume is expressed in "cubic units."

So, the volume of the rectangular solid is 105 cubic units.

A square has an area of 49,square feet. what is the perimeter of the square

Answers

The perimeter would end up being 28 inches.

You have to find the square root of 49, and then multiply that number by 4 to get your perimeter.

The lesser of two consecutive even integers is 10 more than one-half the greater. Find the integers.

Answers

Hello,

Here's my solution:

Let n = the lesser of the two consecutive even integers; so what will be a good way to represent the greater of the two consecutive even integers? I say n + 2.

Let's write the equation:
n = ((n+2)/2) + 10

I'll multiply both sides of the equation by 2 to eliminate the denominator, getting:
2n = 2[((n+2)/2) + 10]

This reduces to:
2n = n+2 + 20

Which can be further simplified to:
2n = n+22

Subtracting n from both sides we get:
n = 22

So n, the lesser consecutive even integer is 22. The greater consecutive even integer is 24.

Let's check this solution by substituting n = 22 into our original equation:

n = ((n+2)/2) + 10

22 = ((22+2)/2) + 10
22 = ((24)/2) + 10
22 = (12) + 10
22 = 22 - it checks!

Really really need help A six-sided number cube is rolled. Find the probability of rolling a 3 or a number greater than 4.

A.1/8
B.1/6
C.1/2
D.2/3

Answers

Well, there are 6 sides.

There are also 6 numbers: 1, 2, 3, 4, 5, 6

Okay, so the probability of rolling a 3 is 1/6 because that is just one number of the 6.

Okay, number greater than four are 5 and 6, and if you add 3 to that you get 3/6, or 3 out of 6 numbers.

If you simplify 3/6 you get 1/2.

Hope this helps!

There are 6 sides and numbers in the cube. (1,2,3,4,5,6)
Probability of rolling a 3 or a number greater than 4: there are 2 numbers greater than 4 (5 and 6) and one other number (3). In total, there are 3 numbers here.

So the probability of rolling 3 numbers out of 6 is 3/6, which can be simplified to 1/2.

What is the fuction eqation for (0,-2)and (5,-1)

Answers

y = mx + b

m is the slope
b is the y-intercept

First find the slope

$slope = (y_2-y_1)/(x_2-x_1) = (-1+2)/(5-0)= (1)/(5)$

So far we have: y = 1/5x + b

Now we need to find b

y = 1/5x + b

Plug in (0,-2)

-2 = 1/5(0) + b

-2 = b

So the final equation is $\boxed{y=(1)/(5)x-2}$

f(x) = 1/5 x - 2

-2 is your y intercept and using (y-y)/(x-x) you can get slope

(-1 - - 2)/ (5-0) = (-1+2) / (5) = 1/5
