Answer:

x = 2 and y = 7

Step-by-step explanation:

We are given two equations:

1.      8x + y = 23

2. −10x  - y = −27

By adding both equations with each other we get:

(1.+2.) -2x = -4

Which can be reduced to:

(1.+2. : (-2)) x = 2

We can insert x in Equation 1. (or 2) and get:

8*2 + y = 23

16 + y = 23         [-16 on both sides]

y = 7

Resulting in x = 2 and y = 7 as a possible solution for this system.

Answer:

Step-by-step explanation:

8x + y = 23

-10x - y = -27

-2x = -4

x = 2

8(2) + y = 23

16 + y = 23

y = 7

Answer:

P = 10w

Step-by-step explanation:

Number of point per correct spelling = 10

Number of words spelt correctly = w

Total points, p

P = (number of points per correct spelling * number of words spelt correctly)

P = 10 * w

P = 10w

Answer:

48 square units

Step-by-step explanation:

The area of a triangle is calculated by multiplying height to the base and that divided by two

The height of the given triangle is 8 units and the base is 12 units

8×12÷2 = 48

[tex]\pink{\bigstar}[/tex] Area of the triangle is [tex]\large\leadsto\boxed{\tt\purple{48 \: square \: units}}[/tex]

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

✯ In order to find the area of a triangle we must know about 2 parameters i.e, height and base of the traingle.

✯ We need to count the number of grids present inside the triangle or forming the triangle vertically to know about the height of the triangle. Similarly, counting the grids horizontally will give us the base of the triangle.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Following the above steps we get to know the required parameters.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Now moving on, there is a formula to find out the area of a triangle.

[tex]\pink{\bigstar}[/tex] [tex]\large\underline{\boxed{\bf\green{Area_{(triangle)} = \dfrac{1}{2} \times b \times h}}}[/tex]

where,

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Substituting in the Formula:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ [tex]\sf Area_{(triangle)} = \dfrac{1}{2} \times 12 \times 8[/tex]

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ [tex]\sf Area_{(triangle)} = \dfrac{1}{2} \times 96[/tex]

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

★ [tex]\bold\red{Area_{(triangle)} = 48 \: square \: units}[/tex]

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, the Area of the given triangle is 48 square units.

Answer:

(2x^2+7)

Step-by-step explanation:

5x^3 * 2x^2 = 10x^5

5x^3 * 7 = 35x^3

The identity equation is; 5x³(2x² - 7)

This question will be solved with the concept of factorization which involves simplifying an algebraic equation by collecting like terms and putting it in front of a bracket with the remaining terms inside that same bracket.

The algebraic equation we are working with is;

10x⁵ - 35x³

To solve this, we will list out the factors of 10 and 35 and pick the highest common factor.

factors of 10; 1, 2, 5, 10

Factors of 35; 1, 5, 7, 35

Highest common factor is 5

Also, for the x symbol, the highest common factor is xᵃ.

Thus the factor we are bringing to the front of the bracket is 5x³

To get what will remain in the bracket, we will just divide the original terms by 5x; [tex]\frac{10x^{5} }{5x^{3}} - \frac{35x^{3}}{5x^{3}}[/tex]

This gives; 2x² - 7

Thus, The identity equation is; 5x³(2x² - 7)

Answer:

look it up on here someone probably answered it

Answer:

the area of the parallelogram would be 40

to find the area all you need to do it multiply the base by the height. (8×5=40)

Answer:

1. z = 5,  2. w = 9

Step-by-step explanation:

1. 5z - 4 = 21

5z = 21 + 4

5z = 25

z = 25/5

z = 5

2. w/9 + 2 = 3

w/9 = 3 - 2

w/9 = 1

w = 1 x 9

w = 9

Answer:

B

Step-by-step explanation:

Easy that's it. it's simple

Answer:

yes

Step-by-step explanation:

Answer:

Yes these triangles are similar. All angles of a triangle have to equal 180 degrees, a strait line. When you have a right triangle, that already gives you 90 degrees. whatever comes next has to equal to 90. The angles of both triangles match up, DEF is just a scaled down version of ABC

Step-by-step explanation:

since m is parallel to n, this means that the two angles are alternate angles. Hence, 46°=6x-2

Calculate and you should get x = 8°

Answer:

x = 11

Step-by-step explanation:

Theorem:

The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.

Angle ABC is an exterior angle of the triangle.

Angles D and C are its remote interior angles.

m<ABC = m<D + m<C

12x - 2 = 57 + 7x - 4

Combine like terms on the right side.

12x - 2 = 7x + 53

Subtract 7x from both sides.

5x - 2 = 53

Add 2 to both sides.

5x = 55

Divide both sides by 5.

x = 11

Answer: x = 11

Answer:

According to exterior angle property, one of the exterior angles of a triangle is equal to the sum of the opposite 2 interior angles.

Thus,

12x-2= 57+7x-4

= 12x = 57-4+7x

= 12x = 53+7x

= 53= 7x-12x

= 53=-5x

= 53÷-5=x

= x= 10.6

Thus x= 10.6

Step-by-step explanation:

Answer:

Jeanette is the friend walking at the same rate as Caroline. This is because Jeanette also takes 1/5 of an hour to walk a mile.

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

It takes Caroline 1/5 of an hour to walk a mile. Four of Caroline's friends time themselves on their own walk of different lengths. Which friend is walking at the same rate as Caroline? If:

David walked 1/2 a mile in 2/5 an hour

Jeanette walked 1/2 a mile in a 1/10 an hour

Kay walked 1/5 a mile 1/2 a hour

Mark walked 1/3 a mile in 3/5 an hour

The explanation of the answer is now given as follows:

To determine which friend is walking at the same rate as Caroline, we first convert their rate to number hours it takes to walk a mile as follows:

a. David walked 1/2 a mile in 2/5 an hour

This implies that:

(1 / 2) * 2 = 2/2 = 1 mile

(2 / 5) * 2 = 4/5 of an hour

Therefore, David takes 4/5 of an hour to walk a mile.

b. Jeanette walked 1/2 a mile in a 1/10 an hour

This implies that:

(1 / 2) * 2 = 2/2 = 1 mile

(1 / 10) * 2 = 2 / 10 = 1/5 of an hour

Therefore, Jeanette takes 1/5 of an hour to walk a mile.

c. Kay walked 1/5 a mile 1/2 a hour

This implies that:

(1 / 5) * 5 = 5/5 = 1 mile

(1 / 2) * 5 = 5 / 2 = 2.5 hours

Therefore, Kay takes 2.5 hours to walk a mile.

d. Mark walked 1/3 a mile in 3/5 an hour

This implies that:

(1 / 3) * 3 = 3/3 = 1 mile

(3 / 5) * 3 = (3 * 3) / 5 = 9 / 5 = 1.8 hours

Therefore, Kay takes 1.8 hours to walk a mile.

Conclusion.

Based on the calculations above, only Jeanette is walking at the same rate as Caroline. This is because Jeanette also takes 1/5 of an hour to walk a mile.

Answer:

5

Step-by-step explanation:

Answer:

5 miles

Step-by-step explanation:

Hi there!

To find the rate at which Gia can run, you have to divide 4 by 32 to find how many miles she runs per min. When you do that, you get .125 Gia runs .125 miles per min. To find how many miles she runs in 40 min, you multiply .125 by 40 to get 5. This means that Gia runs 5 miles in 40 min.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer this by inserting a positive number between the '6x' and the '=' sign and then subtracting the same number:

x^2 + 6x + 9 - 9 = -2

Where does the "9" come from?  Take half the coefficient of x (which is 6) and square the result (obtaining 36).  Now add 36 after the "6x" and then subtract 36:

x^2 + 6x + 9 = 7

Rewrite this with a perfect square on the left side:

(x + 3)^2 = 7            Here we have successfully "completed the square."
