Step-by-step explanation:

Just add all numbers together.

Answer:

The answer is 36 adults and 88 children.

Step-by-step explanation:

The two equations are:

x+y=124 and 5x+3y=444

Using substitution method:

5x+3(124+x)=444

5x+372-3x=444

2x=72

x=36

5(36)+3y=444

180+3y=444

3y=264

y=88

Answer:

y=19.6

Step-by-step explanation:

Depth=3.18cm

Step-by-step explanation:

V=πr2h

1LITRE=1000CM3

Answer:

y=7x

Step-by-step explanation:

When finding the slope intercept form using 2 points, we do the following.

y=mx+b (Slope intercept from)

y=7x+b (7 is slope)

Substitute the point

7=7(1)+b

7=7+b

b=0

y=7x

The slope intercept equation is y = 7x

Answer:

  4, 5, 6

Step-by-step explanation:

Let x represent the middle one. Then the sum of the first two is ...

  (x -1) +x

And we want that to be 3 more than the third:

  (x -1) +x = (x +1) +3

  2x = x +5 . . . . . . . . . add 1, simplify

  x = 5 . . . . . . . . . . . . . subtract x

Since 5 is the middle integer, the three integers are ...

We'll use the zero product property to solve.

[tex]3(x^2+5)^2(x^2-25)^3(x-8)^4 = 0\\\\(x^2+5)^2=0 \text{ or } (x^2-25)^3=0 \text{ or } (x-8)^4 = 0\\\\x^2+5=0 \text{ or } x^2-25=0 \text{ or } x-8 = 0\\\\x^2=-5 \text{ or } x^2=25 \text{ or } x = 8\\\\x=\pm\sqrt{-5} \text{ or } x=\pm\sqrt{25} \text{ or } x = 8\\\\x=\pm i\sqrt{5} \text{ or } x=\pm 5 \text{ or } x = 8\\\\[/tex]

where [tex]i = \sqrt{-1}[/tex]

----------------------

The notation [tex]x=\pm i\sqrt{5}[/tex] breaks up into [tex]x=i\sqrt{5} \text{ or } x=-i\sqrt{5}[/tex]. The multiplicity of these two roots is 2 as it's the exponent of the factor [tex](x^2+5)^2[/tex]. Focus on the outermost exponent.

The notation [tex]x = \pm 5[/tex] becomes [tex]x = 5 \text{ or } x = -5[/tex]. The multiplicity of these two roots is 3 since it's the outermost exponent of the factor [tex](x^2-25)^3[/tex]

And finally, the multiplicity of the root x = 8 is 4 because it is the outermost exponent of the factor [tex](x-8)^4[/tex]

Answer:

Step-by-step explanation:

isosceles triangles are ones that have two equal sides and angles. this would mean that ab is equal to bc. then you substitute the values in for AB=BC, 3x-4=5x-10. you bring the variables to one side and you flip everything which is then 2x=6 and then divide by 2. this would be x=3. then you have to figure out the AB. 3(3)-4=5. then you can always check for BC, 5(3)-10=5. and they are equal! hope i helped!

Step-by-step explanation:

Solving the expressions

7)

given the expression

[tex]\left(-7\right)+\:\left(-10\right)\:-\:5\:+2[/tex]

so

[tex]=\left(-7\right)-10-5+2[/tex]

[tex]=-17-5+2[/tex]

[tex]=-22+2[/tex]

[tex]=-20[/tex]

8)

[tex]\left(-9\right)+4+\left(-8\right)-\left(-7\right)[/tex]

so

[tex]=-5+\left(-8\right)-\left(-7\right)[/tex]

[tex]=-5-8-\left(-7\right)[/tex]

[tex]=-13-\left(-7\right)[/tex]

[tex]=-13+7[/tex]

[tex]=-6[/tex]

9)

[tex]\left(-6\right)\:-\:\left(2\:\times \:4\right)\:-\:\left(-1\right)\:[/tex]

so

[tex]\left(-6\right)-\left(2\times \:4\right)-\left(-1\right)[/tex]

Calculate within parentheses

[tex]=\left(-6\right)-8-\left(-1\right)[/tex]

[tex]=-14-\left(-1\right)[/tex]

[tex]=-14+1[/tex]

[tex]=-13[/tex]

10)

[tex]\left(-8\right)\:+\:\left(-4\:\div \:-4\right)\:-\:8[/tex]

solving

[tex]\left(-8\right)+\left(-\frac{4}{-4}\right)-8[/tex]

[tex]\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a[/tex]

[tex]=-8-\frac{4}{-4}-8[/tex]

[tex]=-8-\left(-1\right)-8[/tex]

[tex]\mathrm{Apply\:rule}\:-\left(-a\right)=a[/tex]

[tex]=-8+1-8[/tex]

[tex]\mathrm{Add/Subtract\:the\:numbers:}\:-8+1-8=-15[/tex]

The value of the given expression 7) (-7) + (-10) – 5 +2 is -20, 8) (-9) + 4 + (-8) – (-7) is -6, 9) (-6) – (2 x 4) – (-1) is -11, 10) (-8) + (-4 ÷ -4) – 8 is -15.

BODMAS stands for B- bracket, O- order, D-division, M-multiplication, A- addition, S- subtraction. We use this rule when there is more than one operation are present in the mathematical expression.

7)  (-7) + (-10) – 5 +2

here, we will use the BODMAS rule, the addition and subtraction will go from left to right.

= -7 -10 -5 + 2

= -17 -5 + 2

= -22 + 2

= -20

8) (-9) + 4 + (-8) – (-7)

=  -9 +4 -8 +7

= -5 -8 +7

= -13 + 7

= -6

9) (-6) – (2 x 4) – (-1)

= -6 - 8 +1

= -12 + 1

= -11

10) (-8) + (-4 ÷ -4) – 8

= -8 -4/ (-4) - 8

= -8 +1 -8

= -7 -8

= -15

Therefore, the value of the given expression 7) (-7) + (-10) – 5 +2 is -20, 8) (-9) + 4 + (-8) – (-7) is -6, 9) (-6) – (2 x 4) – (-1) is -11, 10) (-8) + (-4 ÷ -4) – 8 is -15.

Answer:

z = 18.5

y = 15.5

x = 15.5

Step-by-step explanation:

Let

tulips = x

lilies = y

roses = z

x = y

z= x + 3 or y + 3

The equation is

0.18x + 0.27y + 0.55z = 17.15

Substitute x = y and z = y + 3 into the equation

0.18y + 0.27y + 0.55(y + 3) = 17.15

0.18y + 0.27y + 0.55y + 1.65 = 17.15

y = 17.15 - 1.65

= 15.5

x = y

x = 15.5

z = x + 3

= 15.5 + 3

= 18.5

Therefore,

z = 18.5

y = 15.5

x = 15.5

Answer:

The function of g(x) = 5x + 2

Step-by-step explanation:

Let us use the composite function to solve the question

∵ f(x) = 2x - 1

∵ f(g(x)) = 10x + 3

→ f(g(x)) means substitute x in f(x) by g(x)

∴ f(g(x)) = 2[g(x)] - 1

→ Equate the two right sides of f(g(x))

∴ 2[g(x)] - 1 = 10x + 3

→ Add 1 to both sides

∴ 2[g(x)] - 1 + 1 = 10x + 3 + 1

∴ 2[g(x)] = 10x + 4

→ Divide each term into both sides by 2

∵ [tex]\frac{2[g(x)]}{2}[/tex] = [tex]\frac{10x}{2}[/tex] + [tex]\frac{4}{2}[/tex]

∴ g(x) = 5x + 2

∴ The function of g(x) = 5x + 2
