percent of the marbles are white?

Inequalities are used to represent unequal expressions

The solution to the inequality is: [tex]x > -3[/tex]

The inequality is given as:

60>5(6-2x)

Rewrite the inequality properly as:

[tex]60>5(6-2x)[/tex]

Divide both sides of the inequality by 5

[tex]12>6-2x[/tex]

Subtract 6 from both sides of the inequality

[tex]6>-2x[/tex]

Divide both sides of the inequality by -2

[tex]-3

Rewrite the inequality as

[tex]x > -3[/tex]

Hence, the solution to the inequality is: [tex]x > -3[/tex]

Answer: 144 ft

Step-by-step explanation:

352/22=16 16*9=144=length 16*2=32=width

Answer:

144 feet

Step-by-step explanation:

The ratio is 9:2 so if you add the ratio and multiply it by two because there are four sides NOT two so then you get twenty-two. Divide 352 by 22 and you get 16 now multiply nine by sixteen because you are trying to find the length.

Answer:

It is therefore a exponential function, as y increases with x.

Step-by-step explanation:

coordinates: ( 7 , 5 ) , ( 16 , 10 )

Slope: [tex]\frac{y2-y1}{x2-x1}[/tex]

         : [tex]\frac{10-5}{16-7}[/tex]

         : [tex]\frac{5}{9}[/tex]

equation: y - y1 = m( x - x1 )

              : [tex]y - 5 = \frac{5}{9}(x - 7)[/tex]

              : [tex]y = \frac{5}{9}x+\frac{10}{9}[/tex]

check if third coordinates matches:

[tex]y = \frac{5}{9}(25)+\frac{10}{9}[/tex]

[tex]y = 15[/tex] ......does not match, so its not linear.

Answer:

0.2+ 4.5 = 4.7

Step by step explanation:-

0.2+? =4.7

0.2 + x =4.7

x = 4.7-0.2

x = 4.5

Answer:

0.2 + ? =4.7

let missing num be x ,

0.2 + x = 4.7

or, x = 4.7 - 0.2

x = 4.5

0.2 + 4.5 = 4.7

Answer:

height = 14.2 m , base = 7.1 m

Step-by-step explanation:

let the base be b then height h = 2b

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh

Here A = 50 , then

[tex]\frac{1}{2}[/tex] × b × 2b = 50

b² = 50 ( take square root of both sides )

b = [tex]\sqrt{50}[/tex] ≈ 7.1 ( to the nearest tenth )

Then base = 7.1 m and height = 2 × 7.1 = 14.2 m

Given that ACE is an isosceles triangle, the measure of ∠CDB is: 55°

The two base angles of any isosceles triangle are always congruent to each other.

Therefore:

m∠CBD = m∠CDB

m∠CBD = 180° - 125° (supplementary angles)

m∠CBD = 55°

Therefore:

m∠CBD = m∠CDB = 55°

In summary, given that ACE is an isosceles triangle, the measure of ∠CDB is: 55°

Answer:

n = -13

Step-by-step explanation:

√10 - 3n = 7 ⇔

⇔ 10 - 3n = 49 ⇔ We need to remove the square root. Ex: √n = 2 ⇔ n = 2²

⇔  -3n = 49 - 10 ⇔
⇔ -3n = 39 ⇔
⇔ n = [tex]\frac{39}{-3}[/tex] = -13 (as -3 changes members, as it was multiplying, it now divides, conversion).
