The reason we solve systems of equation is to find where the equation

Answer:

angle-side-angle. that's my answer

Answer:

∠ABC = 54°

Step-by-step explanation:

an inscribed angle is 1/2 the size of an incenter angle.

so:

∠AMC = 2(∠ABC)

10x - 12 = 2(4x + 6)

10x - 12 = 8x + 12

simplify:

2x = 24

x = 12

∠ABC = 4(12) + 6 = 54°

Answer:

The greatest common factor is 20

Step-by-step explanation:

Rewrite 40 as 20*2

Rewrite 60 as 20*3

=20*3m-20*2

Factor out common term 20;

20(3m-2)

Answer:

Well so if we multiply 6.42*106=680.52.

then subtract 680.52-428000=427319.48

there you go:)

Step-by-step explanation:

Answer:

338 or 335 they both get rounded of to the nearest 5

2 possible numbers for the actual number of marbles 338 and 335, are rounded to the nearest 5.

We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.

To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.

Given, Thabo rounded the number of marbles to the nearest 5 and his answer was 340.

Therefore, 2 possible numbers for the actual number of marbles could be

Whether it's 338 or 335, both numbers are rounded to the nearest 5.

Answer:

12

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ 3, 6 ] , then

f(b) = f(6) = 6² + 3(6) + 2 = 36 + 18 + 2 = 56

f(a) = f(3) = 3² + 3(3) + 2 = 9 + 9 + 2 = 20 , then

average rate of change = [tex]\frac{56-20}{6-3}[/tex] = [tex]\frac{36}{3}[/tex] = 12

Answer:

x= 9

Step-by-step explanation:

Please see the attached picture.

In △BCD

∠BDC= 180° -90° (adj. ∠s on a str. line)

∠BDC= 90°

Applying Pythagoras' Theorem,

(BD)² +(DC)²= (BC)²

(BC)²= 6² +4²

(BC)²= 52 -----(1)

In △ABD

Applying Pythagoras' Theorem,

(AD)² +(BD)²= (AB)²

(AB)²= x² +6²

(AB)²= x² +36 -----(2)

In △ABC

Applying Pythagoras' Theorem,

(AB)² +(BC)²= (AC)²

(AB)² +(BC)²= (x +4)²

Substitute (1) and (2):

x² +36 +52= (x +4)²

x² +88= x² +2(x)(4) +4² (simplify, expand)

x² +88= x² +8x +16

8x +16= 88 (-x² on both sides)

8x= 88 -16

8x= 72

x= 72 ÷8

x= 9

Answer:x= -1, x=7

Step-by-step explanation: You will want to use the quadratic formula

X=-24)+/-[(-24)^2-4*4(-28)/2.4

Then separate the equations

x=24+32/8  And x=24-32/8

so x=7 and x= -1

Answer:

Total number of students = 360

Total number of girls = 120

Total number of boys = x / ?

120/240= 1/2

50%

Step-by-step explanation: To find out the percent of the boys you first

subtract the whole amount of students which is 360 students in total to the number of girls (120) resulting 240. 240 in ratio is 1/2. 1/2 is 50%.
