Answer:

x = 5

Step-by-step explanation:

8x + 50 = 90

or, 8x = 90-50

or, 8x = 40

so, x = 5

Answer:

16 rows

Step-by-step explanation

48x10=480, then divide 480 by 30. 480÷30=16. So, there will be 16 rows.

Answer: 2.3c-13.4

Step-by-step explanation:

We can combine the constants and c's separately. We first do -6.5-5.1-1.8 which equals -13.4 and add that to 2.3c to get 2.3c-13.4

Answer:

Step-by-step explanation:

it’s actually-4.2c-69 :)

Answer:

Step-by-step explanation:

By similar triangles law:-

[tex]\frac{24}{2x} =\frac{30}{x+6}[/tex]

[tex]24(x+6)=30(2x)[/tex]

[tex]24x+24(6)=60x[/tex]

[tex]24x+144=60x[/tex]

[tex]\frac{36x}{36x} =\frac{144}{36}[/tex]

[tex]x=4[/tex]

Since AB=x+6+2x

[tex]AB=3x+6[/tex]

Substitute value of x

[tex]AB=3(4)+6[/tex]

[tex]AB=12+6[/tex]

[tex]AB=18[/tex]

Therefore, the third side of ΔABC is 18.

Answer:

x = -3 y = -8 (-3,-8)

Step-by-step explanation:

first you would subsitute the y with (2x-2) in -3x+4y=-23 as y=2x-2

giving you-3x+4(2x-2)=-23

next you distribute the 4 to (2x-2) leaving you with -3x+8x-8=-23

then add -3x+8x to get 5x, having 5x-8=-23

add 8 to both sides canceling out 8 on one side and adding 8 to the other leaving you with 5x=-15 then you divide 5 from 5x to both sides leaving you with x = -3

next is y since you have x you would substitute the x in y=2x-2 with -3 getting y=2(-3)-2 then you multiply the 2 and -3 so you have y=-6-2 then you subtract those getting y = -8

Answer:

20 ÷ [tex]\frac{5}{3}[/tex] = 12

Step-by-step explanation:

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

20 x 3 divided by 5 = 60\5

Thus, the answer to 20 divided by 5/3 in fraction form is:

[tex]\frac{60}{5} = 12[/tex]

Step-by-step explanation:

just multiply.

you apply a fraction to a quantity by multiplying the fraction with the quantity.

a.

2/3 of 3/4 = 2/3 × 3/4 = 6/12 = 1/2

b.

2/5 of 3/4 = 2/5 × 3/4 = 6/20 = 3/10

c.

2/5 of 4/5 = 2/5 × 4/5 = 8/25

d.

4/5 of 3/4 = 4/5 × 3/4 = 12/20 = 3/5

8 x - 1/2 = -4 - middle line

-3/4 x 8 = - 6 - side line

-3/4 - - 1/2 = -1/4 - top line

-1/2 - 1/2 = -1 - vertical line

The function gets shifted towards the left then the value of h must be negative. The correct option is B.

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

Given

The function is  f(x) = |x – h| +  k

We know that if we subtract h from the variable the function gets shifted towards the right but in the graph, the function gets shifted towards the left then the value of h must be negative.

We know the coordinate of the vertex is (-1.5, -3.5). Then abscissa will satisfy the |x - h|.

h = -1.5

Thus, option B is correct.
