C) 58

D) 60

A)48

Explanation:

2^3 - 2^2 = 8 - 4 = 4

3^3 - 3^2 = 27 - 9 = 18

4^3 - 4^2 = 64 - 16 = 48

5^3 - 5^2 = 125 - 25 = 100

6^3 - 6^2 = 216 - 36 = 180

7^3 - 7^2 = 343 - 49 = 294

Step-by-step explanation:

An ordered pair that satisfies all the equations in a linear system of equations is called a(n) __________ of the linear system.

Answer:solution

Step-by-step explanation:

An **ordered pair** that satisfies all the equations in a **linear system** of **equations** is called a: solution of the linear system.

A **linear function** is a **function** that has a **positive relationship **between its **variables**.

Hence, an increase in one **variable** (input variable) causes an increase in the other **variable** (output variable) because the **variables** are directly proportional.

Mathematically, the graph of a **linear function** is a straight-line and its **slope** is always constant.

On a related note, a **linear system** of equation is an algebraic equation of the first order with two **variables** and each of its term having an exponent of one.

Generally, a system of linear equations in two variables must have at least two solution.

In conclusion, a **solution** of the **linear system** is an **ordered pair** that satisfies all the equations in a **linear system** of equations.

Find mWYZ as well Find mACB please help with both. Thank you every much! Triangles, Need help, right now I’m does adding more stuff so it can stop saying 20 characters.

Answer:

m<WYZ = 23°

m<ACB = 87°

Step-by-step explanation:

Problem 1: Find WYZ

Given,

m<WVX = (3x - 7)°

m<VYZ = (16x - 3)°

∆WYZ ~ ∆WVX, therefore:

m<WYZ = m<WVX (corresponding angles of similar triangles are congruent)

m<WYZ = (3x - 7)° (substitution)

Create an equation to find the value of x.

m<WYZ + m<VYZ = 180° (linear pair)

(3x -7)° + (16x - 3)° = 180° (substitution)

Solve for x

3x - 7 + 16x - 3 = 180

Add like terms

19x - 10 = 180

Add 10 to both sides

19x - 10 + 10 = 180 + 10

19x = 190

Divide both sides by 19

19x/19 = 190/19

x = 10

m<WYZ = (3x - 7)

Substitute x = 10

m<WYZ = 3(10) - 7 = 30 - 7

m<WYZ = 23°

Problem 2: Find m<ACB

Given,

m<A = 62°

m<AED = (11x - 2)°

m<B = (6x + 13)°

∆ADE ~ ∆ACB, therefore:

m<AED = m<B (corresponding angles of similar ∆s are congruent)

(11x - 2)° = (6x + 13)°

Solve for x

11x - 2 = 6x + 13

Collect like terms

11x - 6x = 2 + 13

5x = 15

Divide both sides by 5

5x/5 = 15/5

x = 3

m<ACB + m<B + m<A = 180° (sum of ∆)

m<ACB + (6x + 13) + 62° = 180° (substitution)

Plug in the value of x and solve

m<ACB + (6(3) + 13) + 62° = 180°

m<ACB + (6(3) + 13) + 62° = 180°

m<ACB + (18 + 13) + 62° = 180°

m<ACB + 31° + 62° = 180°

m<ACB + 93° = 180°

Subtract 93 from both sides

m<ACB = 180° - 93°

m<ACB = 87°

15 men can dig a ditch in 10 days, how many day

Will 10men take working at the same rate

**Answer:**

If 10 men dig a ditch in 12 days .

Total man-days required to dig the ditch

= 10 men × 12 days

= 120 man-days

how long would 15 men take to dig it?

No of days required to finish the job by 15 men

= 120 men-days / 15 men

= 8 days

Answer: 8 days will be required to finish the job by 15 men

Jared bought a cell phone for $42, Juanita spent 1 1/2 times as much how much did she spend

**answer:**

Juanita spent 1 1/2 times as much as Jared, how much did she spend?

$63

**explanation:**

one and a half of 42 is: 63

so,

the answer is Juanita spent $63!

Juanita paid $63 for the **phone**, which is **equal **to 3/2 of what Jared paid while buying the phone.

Follow these procedures to convert an incorrect fraction to a mixed number:

Given: Jared spent $42 on a cell phone.

We need to determine 1 and 1/2 which is 3/2 of total amount spent by Juanita.

So,

42(3/2) = $63

Therefore, Juanita spent $63 which is 3/2 **amount** spent by Jared in buying the** cell phone.**

Write the slope-intercept form of the equation for

each graph described.

Line passing through (-2,-8) and (9,-8)

**Answer:**

y=-8

**Step-by-step explanation:**

First find the slope which is rise over run which equals (y2-y1)/(x2-x1)

(-8-(-8))/(9-(-2))

(-8+8)/(9+2)

0/11

slope = 0

Now you have the slope of 0. You can plug in one of the given point (x,y) to find b

If a, b and c are positive integers for which (a,b,c) is the only

ordered triple such that 6a +9b + 20c = 61, then what is

a+b+c?

If *a*, *b*, and *c* are all positive integers and 6*a* + 9*b* + 20*c* = 61, then right away you know *c* < 3, because if *c* = 3, then 20*c* = 60, and there are no solutions for *a* and *b*.

So consider two cases:

• If *c* = 2, then we're left with 6*a* + 9*b* = 21.

• If *c* = 1, then 6*a* + 9*b* = 41.

We have gcd(6, 9) = 3, but 41 is prime and 3 does not divide 41. So we throw out the second case.

This leaves us with 6*a* + 9*b* = 21. Notice that if *a* = *b* = 1, then 6*a* + 9*b* = 15. Add 6 to both sides to get 21. So *a* = 2, *b* = 1, and *c* = 2, and hence *a* + *b* + *c* = **5**.
