solve for x. 0.9(x+1.4)−2.3+0.1x=1.6

Answer:

The given ratio is 3:4 this means there are 7 people in each unit of this ratio.

It is stated that there are 35 students in total . That would mean that there are

5 Total sets of students in this class . When we multiply the numbers in our starting ratio by this multiple of 5 , our ratio now becomes 15 : 20

15 and 20 do indeed add up to 35 … But , our question wants to know how many more GIRLS are in the class . Boys were calculated to be 15 in number .

Girls were calculated to be 20 in number .

We now know there were 5 more girls than boys in that class ..

5 is your answer .

total number of student in class=35

let the number of boys be 3x

let the number of girls be 4x

so therefore 3x+4x=35 =>7x=35 =>x=5

so therefore number of boys in class is 3x=>3(5)=15

and number of girls in class is 4x=>4(5)=20

so there are 20–15=5 more girls in class than boys.

Let the number boys in the class be b. So b/(35-b)=3:4, or 105-3b=4b, or 7b=105, or b=15. The number of girls in the class is 35-15=20 20-15=5

Ans: there are 5 more girls than the number of boys in the class.

Step-by-step explanation:

Answer:

0, 1 and 2

Step-by-step explanation:

- 1 < x ≤ 2

has solutions x = 0, 1, 2

- 2 ≤ x < 3

has solutions x = - 2, - 1, 0, 1, 2

Thus the values of x that satisfy both are x = 0, 1, 2

Inequalities are used to represent unequal expressions.

The integer values satisfy both inequalities are 0, 1 and 2

The inequalities are given as:

[tex]\mathbf{-1 < x \le 2}[/tex] and [tex]\mathbf{-2 \le x < 3}[/tex]

First, we list out the elements of both inequalities

[tex]\mathbf{-1 < x \le 2}[/tex]

[tex]\mathbf{x = 0,1,2}[/tex]

[tex]\mathbf{-2 \le x < 3}[/tex]

[tex]\mathbf{x = -2 ,-1, 0, 1,2}[/tex]

0, 1 and 2 are common integers between both inequalities

Hence, the integer values satisfy both inequalities are 0, 1 and 2

Answer:

4x + 3y = 6 is: y = 3/4x - 3/2

3x + 4y = -6 is: y = 4/3x - 2

3x - 4y = 6 is: y = 4/3x + 2

4x - 3y = -6 is: -3/4x - 3/2

Hope this helps! :)

The correct matches are,

4x + 3y = 6 is: y = 3/4x - 3/2

3x + 4y = -6 is: y = 4/3x - 2

3x - 4y = 6 is: y = 4/3x + 2

4x - 3y = -6 is: y=-3/4x - 3/2

Complementary, x=78

Step-by-step explanation:

90= (x-8)+20

complementary angles add up to 90 degrees.

Answer:

Complementary, x is 78

Step-by-step explanation:

Let's first define what complementary and supplementary angles are. Complementary angles add up to 90 degrees, and supplementary add up to 180. From this image, we can see that this is a right angle. Right angles add up to 90 degrees, therefore, this is a complementary angle.

Now, because we know that it is 90 degrees and that (x-8)+(20) = 90, then we can solve for x. However, if the angle is unknown, then we would do x-8=20. In this case, sense we know for sure this angle is complementary, we do

(x-8)+(20) = 90

X+12=90 We combined like terms

X=78 Inverse operations

You can plug 78 into x and check to see if it is correct if they are 90 degrees total.

Answer:

Step-by-step explanation:

There's 24 students so I would do 5 × 24 which equals 120 so 420 - 120 is 300. Then 2 × 24 is 48. Now 300-48 is 252. They would have $252 left.

Answer:

d

Step-by-step explanation:Angle 12 & 10 are effectively corresponding angles, but angle 10 & 7 are alternate interior angles. Anyways, Angle 12 & 10 are congruent and 10 & 7 are congruent. At the end, the three angles 12, 10, and 7 have the same measure. If we put it otherwise, the line B is intersecting line D which form right angles equals to 90 degrees, so angle 12 = 90, and the same happens with angle 10 and 7, so the three angles are congruent, but at the same time, angle 7 is supplementary with angle 12 because their sum is equal to 180, (90 + 90 = 180). If you think from different angles is hard to choose the right answer, so what I guess is that we don't need to take into account the angle 10, just the fact that line A intersect line C, and Line B intersect line D forming right angles, and that angle 7 and 12 are right angles which sum equals 180, therefore, we could say that they are supplementary angles, but also congruent because they measure the same, so at the end,

The given function is

[tex]h(x) = \{ (0,1), (2,3), (-4, 1) \}[/tex]

The inverse function is

[tex]h^{-1}(x) = \{ (1,0), (3,2), (1,-4)\}[/tex]

To get the inverse, we swap each x and y coordinate.

The rule is [tex](x,y) \to (y,x)[/tex]

So that's why the point (0,1) becomes (1,0) for instance.

Answer:definition of midpoint, angle BCA is congruent to angle DCA

The triangles ΔABC and ΔADC are congruent triangles by

a) definition of mid-point

b) measure of ∠ACB = measure of ∠ACD = 90°

Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape

The three sides are equal (SSS: side, side, side)

Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)

Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)

A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)

Given data ,

Let the first triangle be represented as ΔABC

Let the second triangle be represented as ΔADC

Now , the side AC is the common bisector of both the triangles such that

C is the midpoint of BD

So , the measure of side BC = measure of side CD

And , the perpendicular bisector is right angle

So , the measure of ∠ACB = measure of ∠ACD = 90°

And , the measure of AC = measure of AC ( reflexive property )

Therefore , the triangles are congruent by SAS theorem

Hence , the triangles are congruent
