Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question;

A kid traveled a distance of 9 km by bike, and then walked a distance of x km.

a.Find the total distance traveled in terms of  x

b. If the total distance was less than 30 km, form an inequality in x, and

then solve it!

a) Total distance = distance travelled by bike + distance walked

Total distance = 9km + xkm

Total distance = (9+x)km

b)  If the total distance was less than 30 km, the inequality representing this is;

9+x < 30

Subtract 9 from both sides;

9+x-9 < 30-9

x < 21

hence the solution to the inequality is x< 21

Answer: 69%

Answer:

X^8 / 256y^20

Step-by-step explanation:

First to make your life easier with this problem reduce the fraction 5/20 = 1/4

x^3/x = x^3-1= x^2

Then you apply the outer exponent

X^2*4 = X^8

4^4= 256

y^5*4 = y^20

X^8 / 256y^20

Answer:

25%

Step-by-step explanation:

Given parameters:

Amount earned by Jessica per month = 800

Total savings target per year  = 2400

Unknown:

Percentage of savings = ?

Solution:

The total earning per year will be the amount earned per month multiplied by the total number months;

 Amount earned in a year = 12 x 800  = 9600

Let the percentage of savings per year  = y%

  Now;

              2400 = [tex]\frac{y}{100}[/tex] x 9600

                  y = 25%

Answer:

-2

Step-by-step explanation:

-2-4/3-0=-2

you basically take the y value of the first point subtract it from the y value of the 2nd point. you do the same for the x values

Answer:

-2

Step-by-step explanation:

You can use the equation rise over run, which is basically y2-y1 over x2-x1

Y2 is -2 and y4 is 4, x2 is 3  x1 is 0

-2-4 over 3-0=-6/3=-2

Answer:

[tex]34 + 51 = 85[/tex]

Step-by-step explanation:

Given

[tex]34 + 51[/tex]

Required

Use GCF and distributive property to determine the sum

34 can be expressed as:

[tex]34 = 2 * 17[/tex]

51 can be expressed as:

[tex]51 = 3 * 17[/tex]

So, the GCF of both numbers is 17

[tex]34 + 51[/tex] can then be expressed as:

[tex]2 * 17 + 3 * 17[/tex]

Apply Distributive Property, we have:

[tex]17(2 + 3)[/tex]

Solving further:

[tex]17 * 5[/tex]

[tex]85[/tex]

Hence:

[tex]34 + 51 = 85[/tex]

Answer: [tex]7\dfrac12[/tex] cups of flour is required for 3 sticks of butter.

Step-by-step explanation:

We assume that quantity of flour is proportional to butter.

Given : The recipe calls of [tex]1\dfrac14[/tex] cups of  flour  and [tex]\dfrac12[/tex] stick of butter.

Let [tex]x_1=1\dfrac14=\dfrac{5}{4}[/tex]      [tex]y_1=\dfrac{1}{2}[/tex]

For [tex]y_2=3[/tex] , we will find [tex]x_2[/tex] by using formula of direct proportion: [tex]\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}[/tex]

[tex]\dfrac{\dfrac{5}{4}}{\dfrac12}=\dfrac{x_3}{3}\\\\\Rightarrow\ \dfrac{5}{2}=\dfrac{x_3}{3}\\\\\Rightarrow\ x_3=\dfrac{5}{2}\times3= \dfrac{15}2=7\dfrac12[/tex]

Hence, [tex]7\dfrac12[/tex] cups of flour is required for 3 sticks of butter.

15/2 cups of flour!

Answer:

[tex]\boxed {\boxed {\sf Isosceles \ triangle}}[/tex]

Step-by-step explanation:

An equilateral triangle has 3 equal sides and angles.

A right triangle contains one right or 90 degree angle.

An isosceles triangle has 2 equal sides and base angles.

A scalene triangle has no equal sides or angles.

The triangle given has the sides of 5 cm, 5 cm, and 7 cm.

Therefore, 2 of the sides are equal and this must be an isosceles triangle.
