PLEASE! FIRST CORRECT ANSWER GETS BRAINLIEST!!
Consider f(x) = 1.8x – 10 and g(x) = −4

Select the equation that can be used to find the input value at which f (x ) = g (x ), and then use that equation to find the input, or x -value.

A) 1.8x – 10 = –4; x = 10/3

B) 1.8x = –4; x = 1.8 x = -20/9

C) 1.8x – 10 = –4; x = -10/3

D) -4 = x

Answer:

6x = 360-138

x= 222/6

x= 37°

Answer:

x = 42˚

Step-by-step explanation:

1) Find the angle shared by 138˚. 180-138 = 42˚.

2) Now we know that one of the angles in the pentagon is 42˚.

3) the other opposite angle is 138˚ as well.

Hopefully this makes sense! I attached a picture below.

Answer:

In order of the blanks from left to right, 30; 6; 2; 1/2; 20; 12; 12; 3/5

Step-by-step explanation:

So the rectangle has an area of 60 inches squared & the equation for the area of a rectangle is width * height. So, you can find the missing term if you just take 60 & divide it by the given number.

60/2 = 30

60/10 = 6

60/30 = 2

60/120 = 1/2

60/3 = 20

60/5 = 12

60/5 = 12

60/100 = 3/5

Answer:

x = 7 ± [tex]\sqrt{15}[/tex]

Step-by-step explanation:

Given

4(x - 7)² - 48 = 12 ( add 48 to both sides )

4(x - 7)² = 60 ( divide both sides by 4 )

(x - 7)² = 15 ( take the square root of both sides )

x - 7 = ± [tex]\sqrt{15}[/tex] ( add 7 to both sides )

x = 7 ± [tex]\sqrt{15}[/tex]

Answer:

y=6x+30

Step-by-step explanation:

y is the total temperature

6x is the increase of temperature by 6° per x hours

30 is the y-intercept, you start with this number

9514 1404 393

Answer:

Step-by-step explanation:

The increase in temperature is the product of the increase per hour and the number of hours: 6x.

The temperature at any time is the sum of the initial temperature (30°) and the increase (6x).

  y = 30 + 6x . . . . . temperature equation

__

This is graphed as a line with an initial value of 30 and a slope of 6. (Note the attached graph has different grid line spacing vertically than horizontally.)

Answer:34 play sports; 46 don't play sports

Step-by-step explanation:

80 total students

48 in band

24 band and sport

24 band only

22 neither

10 sports only

80-22 = 58 participants

58-48 = 10

24 both + 10 sports only = play 34 sports

80-34 = 46 don't play sports

Answer:

Step-by-step explanation:

x = 90 - 54 = 36

Answer:

x = 36

Step-by-step explanation:

The sum of all the angles in a triangle is 180

Add the known angles together

54 + 90 = 144

then subtract 180 and 144 to find x

180 - 144 =36

Answer:

the number of pensioners in the sample is 40

Step-by-step explanation:

The computation of the number of pensioners in the sample is shown below:

Given that

The Ratio of children to adult visitors is 1:2

The ratio of adults to pensioners is 3:4

And, the total number of seats is 85

Based on the above information,

The common ratios we could write as

1.5 : 3 : 4

Now we doubled it

3 : 6 : 8

So, the number of pensioners in the sample is

= 85 × 8 ÷ (3 + 6 +8)

= 40

Hence, the number of pensioners in the sample is 40

Step-by-step explanation:

1. Expand my multiplying the numbers in parentheses by The GCF, (On the side of the parentheses, (7x2=14), (3x1=3), and switch those numbers with the new, expanded numbers with the old, smaller numbers (Don't forget to remove the GCF)

Opposite angles of a parallelogram are equal. Rhombus is also a parallelogram.

So,

5p-32 = 4p

=> 5p-4p-32 = 0

=> p-32 = 0

=> p = 32

Take the ratio

233/2330 ~9.5708

Answer:

[tex]222[/tex] boys

Step-by-step explanation:

Let [tex]x[/tex] = total number of ninth graders. By knowing how many students there are in the grade, we can find for the number of boys.

[tex]\frac{5}{6+5}x = 185[/tex] (number of girls in ninth grade)

[tex]\frac{5}{11}x = 185[/tex]

[tex]x=407[/tex]

To find for the number of boys, we can use substitution:

[tex]\frac{6}{6+5}x = \frac{6}{11}(407)[/tex]

[tex]=222[/tex]

∴ There are [tex]222[/tex] boys in the class.
