Let's find x

[tex]\sf \to g(x) = 90[/tex]

$\sf \to 10x - 10 = 90$

$\sf \to 10x - 10 + 10 = 90 + 10$

or 7.324 in (nearest thousandth)

Step-by-step explanation:

inches : miles

A : B = C : D

6.875 : 4469 = y : 4761

6.875 / 4469 = y / 4761

y = (6.875 / 4469) x 4761

y = 7.32 in (nearest hundredth)

y = 7.324 in (nearest thousandth)

Answer:

the distance between cities C and D is 7.3242 inches.

given:

solve similarities:

[tex]\hookrightarrow \sf \dfrac{6.875}{x} = \dfrac{4469}{4761}[/tex]

[tex]\hookrightarrow \sf 4469(x) = 6.875*4761[/tex]

[tex]\sf 4469x = 32731.875[/tex]

[tex]\hookrightarrow \sf x = \dfrac{32731.875}{4469}[/tex]

The volume of the scoop of ice cream is 14.14 cm³.

The height of the cone that would fit all the ice cream is  6 cm.

In order to determine the  volume of the scoop of ice cream, the formula for the volume of a sphere would be used.

Volume of a sphere = 4/3 x pi x r^3

= 4/3 x 22/7 x 1.5^3 = 14.14 cm³

The formula that can be used to determine the height of the cone is:

Volume of the scoop / (1/3 x π x r²)

14.14 / (1/3 x 1.5² x 22/7) = 6 cm

Answer:

4 bags

Step-by-step explanation:

   First, 5 pounds is equal to 80 ounces.

   Then, when looking at the number line, we see that 80 ounces is right before "96" to represent 4 of the 24 oz bags. This means that he will need to buy 4 bags, according to the number line.

   We can also do it the mathematical way.

-> 80 ounces / 24 ounce bags = 3 [tex]\frac{1}{3}[/tex].

   We cannot buy [tex]\frac{1}{3}[/tex] of a bag, so we round up to 4 bags.

Equations are statements that have equal values, when compared

The true statement about [tex]x^2 + 10x = 11[/tex] are x = 1 and x = -11

The equation is given as:

[tex]x^2 + 10x = 11[/tex]

Rewrite as:

[tex]x^2 + 10x - 11 = 0[/tex]

Expand

[tex]x^2 + 11x - x - 11 = 0[/tex]

Factorize

[tex]x(x + 11) -1( x + 11) = 0[/tex]

Factor out x + 11

[tex](x -1)(x + 11) = 0[/tex]

Solve for x

x = 1 or x = -11

Hence, the true statement about [tex]x^2 + 10x = 11[/tex] are x = 1 and x = -11

Notice that the plane figures above are congruent with each other, so that

x/8 = 4/16

16x = 8 × 4

16x = 32

x = 2

x/5 = 48/6

6x = 5 × 48

6x = 240

x = 40

x/7 = 90/10

10x = 7 × 90

10x = 630

x = 63

3/x = 10/40

10x = 3 × 40

10x = 120

x = 12

Using the information of each pair and thus calculate the value of X, then:

6)x= 2

7)x=40

8)x=63

9)x=12

So calculating the value of X, we have:

16x = 8 × 4

16x = 32

x = 2

7) x/5 = 48/6

Answer:

( [tex]\frac{20}{7}[/tex], - [tex]\frac{12}{7}[/tex] )

Step-by-step explanation:

4x - 5y = 20 → (1)

2x + y = 4 → (2)

subtract 2x fro both sides in (2)

y = 4 - 2x → (3)

substitute y = 4 - 2x into (1)

4x - 5(4 - 2x) = 20 ( distribute parenthesis and simplify left side )

4x - 20 + 10x = 20

14x - 20 = 20 ( add 20 to both sides )

14x = 40 ( divide both sides by 14 )

x = [tex]\frac{40}{14}[/tex] = [tex]\frac{20}{7}[/tex]

substitute this value into (3)

y = 4 - 2([tex]\frac{20}{7}[/tex] ) = [tex]\frac{28}{7}[/tex] - [tex]\frac{40}{7}[/tex] = - [tex]\frac{12}{7}[/tex]

solution is ( [tex]\frac{20}{7}[/tex] , - [tex]\frac{12}{7}[/tex] )

Answer: x=6, y=2, z=0

Step-by-step explanation:

We know from the third equation that z=8-4y

and from the first that x=y+4

Substitute into the 2nd equation,

4(y+4)-7(8-4y)=24

4y+16-56+28y=24

32y-40=24

32y=64

y=2

Meaning x=6 and z=0.
