[tex]m = 2[/tex]
Step-by-step explanation:
[tex]0 = 12 + 2(m - 8)[/tex]
remove the parentheses and distribute 2 through the parentheses[tex]0 = 12 + 2m - 16[/tex]
calculate the difference[tex]0 = - 4 + 2m[/tex]
move the variable to the left hand side and change its sign[tex] - 2m = - 4[/tex]
divide both sides of the equation by -2[tex] = m = 2[/tex]
hope it helps[tex] \: \: \: [/tex]
Answer:
m = 2
Step-by-step explanation:
0 = 12 + 2 ( m - 8 )
→ Expand the brackets
0 = 12 + 2m - 16
→ Add 16 to both sides
16 = 12 + 2m
→ Minus 12 from both sides
4 = 2m
→ Divide both sides by 2
2 = m

Answer:
Area of larger circle = [tex]\pi *r^2=3.14(11^2)=379.94[/tex]
Area of smaller circle = [tex]\pi *r^2=3.14(3^2)=28.26[/tex]
Probability that it lands in the shaded area (smaller circle):

Assume f(x) = -2x + 8 and g(x) = 3x. What is the value of ( g o f) (3)?
Answer:
6
Step-by-step explanation:
when calculating (g of f)(3) you first have to substitute 3 in the f(x) equation which would be -2(3)+8=-6+8=2. then you have to do g of f, which is g(2) in this case, and 3(2)=6.

Which equation has the same solution as 7x−14=21?
Answer:
2x=10
Step-by-step explanation:
7x-14=21
x=5
2x=10 (divide both sides by two)
2x/2 10/2
x=5
Yky. we'd to provide the other options but to do this you need to +14 to both side. 21+14 then -14+14 cancel. so it's now
7x=35 then you divide 7 in both sides 7 cancels 35/7 =5
x=5

Solve for X in the triangle round your answer to the nearest 10th
Step-by-step explanation:
remember : the sum of all angles in a triangle is always 180 degrees.
the law of sines :
a/sin(A) = b/sin(B) = c/sin(C) with the sides being opposite to the angles.
so,
the opposite angle of x is
180 - 90 - 44 = 46 degrees.
x/sin(46) = 6/sin(90) = 6
x = 6×sin(46) = 4.316038802...
rounded x = 4.3

LeAnnne has $4 in dimes and nickels. She has 10 more dimes than nickels. How many nickels does she have?
Answer:
21 she has 21 nickels
Step-by-step explanation:
Googel
The number of nickels LeAnne has 20 and the number of dimes LeAnne has 30.
Given that, LeAnnne has $4 in dimes and nickels.
Let the number of dimes be d and the number of nickels be n.
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
She has 10 more dimes than nickels.
That is, d=n+10
So, 0.05n+0.10d=4
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
5n+10(n+10)=400
5n+10n+100=400
15n=300
n=20
d=n+10
d=30
Therefore, the number of nickels LeAnne has 20.

The equation y = -4X -1 Has a slope of _______ possible answer choices: -4,-1, no slope and 0) and a y-intercept of possible answer choices: -4, -1 0 and no y-intercept)_______?
Answer:
slope = - 4 , y- intercept = - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 4x - 1 ← is in slope- intercept form
with slope m = - 4 and y- intercept c = - 1
Answer:
-4 then -1
Step-by-step explanation:
The number behind the x value is the gradient and the last number is the y - intercept.
three fifths of the children in a school are boys seven eighths of the girls in the school are right handed. What fractions of the children in the school are left handed girls?
Answer:
Step-by-step explanation:
Firstly, we need to get the fraction that are girls
What we have to do is to subtract the three-fifths from the total fraction of 1
Mathematically,that would be :
1- 3/5=2/5
We have it that seven-eigths of the girls are left-handed. This mean one-eight of the girls are left handed
To get the fraction of the school that are left handed, we multiply the fraction of girls by the fraction of left-handed girls
We have this as:
1/8 x 2/5=1/20
We have it that 1/20 of the children are left-handed girls

Answer:
the answer is x = 4.

2. use a coordinate plane to check your answer.
hope this helps.
Answer:
x = 4
Step-by-step explanation:
(x - 3)(x² + 3x + 9) = 37 ← distribute left side
x³ + 3x² + 9x - 3x² - 9x - 27 = 37 , simplify left side by collecting like terms
x³ - 27 = 37 ( add 27 to both sides )
x³ = 64 ( take cube root of both sides )
x = [tex]\sqrt[3]{64}[/tex] = 4

Answer:
AAS Congruence Theorem
Step-by-step explanation:
the lines in the angle show similarity. so angle FGJ= angle HJG, similarly, angle F= angle H.GJ is the same as JG so this side of both triangles is congruent. since the order of congruency is the same (triangle GHJ: angle H, angle HJG, then JG; triangle JFG: angle F, angle FGJ, then GJ) and the congruent side length isn't between the congruent angles, it's AAS

Answer:
35°
Step-by-step explanation:
As we know vertically opposite angles are equal . So ,
x + 90= 125
x = 125-90 = 35°
Answer:
35
Step-by-step explanation:
125 + 90(APC) + DPA + EPB + x = 360
215 + DPA + EPB + x = 360
DPA = 180 - 125 = 55
EPB = DPA
EPB = 55
X = 90(EPC) - EPB
X = 90 - 55
X = 35
OR easy way
DB is a straight line so angels on it add up to 180
EPB = 180 - 125
EPB = 55
X = 90(EPC) - EPB
X = 90 - 55
X = 35

The grocery store carries diapers for children. Each diaper container has 48 diapers. Two dozen babies each need a container of diapers. How many diapers are needed?
Answer:
1152 diapers are needed
Step-by-step explanation:
2 dozen babies is equall to 24 babies
-(1 dozen is 12 babies)
If 24 babies need a package of diapers which includes 48 diapers, we need to multiply 24x48 which equals 1152 diapers
Answer:1152
Step-by-step explanation:1 DOZEN MEANS 12 SO 2 DOZEN IS 12*2WHICH IS 24
NUMBER OF DIPER A BABY WOULD NEED IS 48
NUMBER OF BABIES IS 12*2 =24
THEREFORE IF 24 BABIES EACH WOULD REQUIRE A CONTAINER WITH 48 DIPERS TOTAL NUMBER OF DIPERS NEEDED IS 24*48 WHICH IS 1152
