Answer:

Step-by-step explanation:

So im gonna be using the substitution method because its easier

We divide the equations into two and solve for y

-6x+y=20

We add 6x to both sides

-6x+y+6x=20+6x

y=6x+20

Now we plug in 6x+20 for y into the other equation

2x+3y=10

2x+3(6x+20)=10 We can simplify now

20x+60=10

20x=-50

take 20 from both sides so its gonna be a fraction

-5/2

We plug in -5/2 for x

y=6(-5/2)+20

y=5

]so therefore x is -5/2 and y is 5

The equality of the expression after removing y by substituting y is 2x + 21 = 10 - 6x + 7 = 20.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.

A formula known as an equation uses the same sign to denote the equality of two expressions.

In another word, the equation must be constrained with some constraints.

Given the expression,

2x + 3y = 10 -6x + y = 20

So,

2x + 3y = 20 and  10 - 6x + y = 20

To remove y we need to find y and substitute.

So by substituting,

10 - 6(20 - 3y)/2 + y = 20

y = 7

So,

2x + 21 = 10 - 6x + 7 = 20

Hence "The equality of the expression after removing y by substituting y is 2x + 21 = 10 - 6x + 7 = 20".

[tex]1)8(m -5 ) = 48 \\ 8m - 40 = 48 \\ 8m = 48 + 40 \\ 8m = 88 \\ \frac{8m}{8} = \frac{88}{8} \\ m = 11[/tex]

[tex]2)x + 7 = 13 \\ x = 13 - 7 \\ x = 6[/tex]

[tex]3)3h - 5 = 12 \\ 3h = 12 + 5 \\ 3h = 17 \\ \frac{3h}{3} = \frac{17}{3} \\ h = 5 \frac{2}{3} [/tex]

Hope this helps you.

Let me know if you have any other questions :-):-)

Answer:

m=11, x=6, h=5 2/3

Step-by-step explanation:

8(m-5) = 48

m-5 = 48/8 = 6

m = 6+5 = 11

m = 11

x + 7 = 13

x = 13-7 = 6

x = 6

3h - 5 = 12

3h = 12 + 5 = 17

h = 17/3 = 5 2/3 or 5.67

Using the subtraction operation, the number of purple bags is 3 more than the number of yellow bags.

Amount of each color available :

Number of Purple bags :

Amount of color required per bag × Amount of purple color

Number of purple bags = [tex]\frac{3}{16} \times 64 = 12[/tex]

Number of Yellow bags :

Amount of color required per bag × Amount of Yellow color

Number of yellow bags = [tex]\frac{3}{16} \times 48 = 9[/tex]

Now we find the difference between the number of Purple and Yellow bags :

Number of purple bags - Number of yellow bags

Difference = 12 - 9 = 3 bags

Therefore, there are 3 more purple bags than Yellow bags.

The expected number of mortgages approved per week and the standard deviation of the distribution are 2.019 and 0.024 respectively.

The expected number of mortgages approved per week :

Expected Number approved = 210 ÷ 104 = 2.019

Hence, it is expected that 2.019 mortageahes would be approved per week.

The standard deviation :

Variance = (59.5414 ÷ 104) = 0.0005698

Standard deviation = √0.0005698

Standard deviation = 0.024

Therefore, the expected value and standard deviation are 2.019 and 0.024 respectively.

We want to see which statement describes the image of a triangle after a dilation of scale factor of 2/3.

We will see that the correct option is C:

"Each angle has the same measure as its corresponding angle in the pre-image."

First, if we have a given figure and we apply a dilation of scale factor K, then all the measures of the given figures are affected by that dilation.

So if the 3 sides of the original triangle measured A, B, and C.

The new measures will be:

Notice that because all the sides changed proportionally, then the internal angles produced did not change after the dilation.

From this, we can conclude that the only correct option is C:

"Each angle has the same measure as its corresponding angle in the pre-image."

This says that the angles of the dilated triangle are the same ones as the angles of the initial triangle, which is true.
