138+710 is the same as _______

The fact for Don's second array is 2x7, indicating there are 2 rows and 7 columns in the array.

In this question, the student is splitting a 4x7 array into a 2x7 array, and another array.

The 4x7 array has 28 elements. After removing a

2x7 array with 14 elements, we're left with an array that also has 14 elements.

We're not given its dimensions, but if we follow the pattern of the original breakup, it could also be a 2x7 array. Therefore, the fact for the second array is 2x7.

By representing this as multiplication, we're showing that there are 2 rows and 7 columns in the array, which represents the total number of elements.

Answer: x=-3/5  y=-41/5

Step-by-step explanation:  Rewrite equations:

y=12x−1;4x−2y=14

Step: Solvey=12x−1for y:

y=12x−1

Step: Substitute12x−1foryin4x−2y=14:

4x−2y=14

4x−2(12x−1)=14

−20x+2=14(Simplify both sides of the equation)

−20x+2+−2=14+−2(Add -2 to both sides)

The system of linear equations is solved by substitution, resulting in the solution x=-3/5 and y=6.2.

To solve the system of linear equations by substitution, start with the given system:

4x − 2y = 14
y = 12x − 1

Since y is already isolated in the second equation, substitute (12x − 1) for y in the first equation:

Now substitute x = −3/5 into the second equation to find y:

The solution for the system of equations is x = −3/5, y = 6.2.

To solve the equation 1/2k + 6 = 4k - 8, subtract 1/2k from both sides, combine like terms, add 8 to both sides, combine constant terms, divide by 3.5, and solve for k to get k = 4.

To solve the algebraic equation 1/2k + 6 = 4k - 8, we need to isolate the variable 'k' on one side of the equation. Here are the steps:

Therefore, the solution to the equation is k = 4.

To solve the problem, we created an equation representing the total cost of 3 T-shirts and a program, and then solved it to find the cost of one T-shirt, which is $25.

Let's denote the cost of one T-shirt as 'T'. Since the total cost of 3 T-shirts and a program is $90, and we know that the cost of the program is $15, we can write our equation as follows: 3T + 15 = 90.

To solve for 'T', we start by subtracting 15 from both sides of the equation, getting us 3T = 90 - 15 = 75.

Next, we would divide both sides by 3 to find the cost of one T-shirt. Hence T = 75 / 3 = $25. So, the cost of one T-shirt is $25.

Answer:  A. 1,131 lbs

Step-by-step explanation:

Given: the weight of each tire of a fully loaded semi truck  = 3,300 lbs

Then the weight of 18 tires of a fully loaded semi truck = [tex]18\times 3300=59400\ lbs[/tex]

Also, the unloaded truck and trailer, with the driver aboard weighs 30,000 pounds.

Therefore, the weight of pallets = [tex]59400-30000=29400\ lbs[/tex]

Hence, the weight  of 26 pallets of cargo when it is fully loaded= 29400 lbs

Now, the weight of each pallet= [tex]\frac{29400}{29}=1130.76923077\approx1131\ lbs[/tex]

∴ The approximate average weight of one pallet of cargo= 1131 lbs

Step-by-step explanation:

With a total of $21, including the discount coupon, and each bottle of olive oil costing $7, you can buy 3 bottles of olive oil.

In your case, you start with $16 and a $5 discount coupon to use at the local supermarket. This gives you an effective total of $16 + $5 = $21 to spend. Each bottle of olive oil costs $7. So, if you divide your total amount of money $21 by the cost of one bottle of olive oil $7, you get 21 ÷ 7 = 3. This means you can buy 3 bottles of olive oil.

The angle is given as 3x - 13 and 58. The measure of angle MNQ (3x - 13) is 32 degrees.

Two angles whose sum is 90° are called complementary angles.

The angle is given as 3x - 13 and 58.

Since the two angles within MNP equal to 90 degrees:

3x - 13 + 58 = 90

3x = 90 - 45

3x = 45

x = 15

Therefore, The measure of angle MNQ (3x - 13) = 32 degrees.

A rectangular prism with dimensions [tex]\(8 \times 5 \times 3\)[/tex] yards has a surface area of 158 square yards, verified by substituting into the surface area formula.

To draw and label a rectangular prism with a surface area of 158 square yards, we first need to understand the surface area formula for a rectangular prism.

The surface area \(A\) of a rectangular prism can be found using the formula:

[tex]\[ A = 2lw + 2lh + 2wh \][/tex]

Where[tex]\(l\), \(w\), and \(h\)[/tex] are the length, width, and height of the rectangular prism, respectively.

Given the surface area[tex]\(A = 158\)[/tex] square yards, we can now find different combinations of [tex]\(l\), \(w\), and \(h\)[/tex] that satisfy this equation.

One possible combination is [tex]\(l = 8\), \(w = 5\), and \(h = 3\).[/tex] Let's verify this:

[tex]\[ A = 2lw + 2lh + 2wh \][/tex]

[tex]\[ = 2(8 \times 5) + 2(8 \times 3) + 2(5 \times 3) \][/tex]

[tex]\[ = 2(40) + 2(24) + 2(15) \][/tex]

[tex]\[ = 80 + 48 + 30 \][/tex]

[tex]\[ = 158 \text{ square yards} \][/tex]

Therefore, a rectangular prism with dimensions [tex]\(8 \times 5 \times 3\)[/tex]yards will have a surface area of 158 square yards.

Now, to draw and label the rectangular prism:

- Draw a rectangular prism with dimensions [tex]\(8 \times 5 \times 3\)[/tex] yards.

- Label the length[tex](\(l\)),[/tex] width [tex](\(w\)),[/tex] and height[tex](\(h\))[/tex] accordingly.
