AC=6.8m

BD is a perpendicular bisector to AC. Because of this AN and NC are created. AN is given as 3.4m. Because AC is bisected it is also split exactly on half. 3.4m is one half so you would multiply 3.4 by two to get the whole measurement of AC. 3.4*2=6.8

Order the following expressions by their values from least to greatest

Licemer1 [7]

Answer:

Step-by-step explanation:

a = -1

b = 2

c = 3

a + (-c) = -1 + (-3) = -4

Both numbers have same sign(-Ve).So add and the result will have the -Ve sign.

c - (-b) = c + b = 3 + 2 = 5

b = 2

Least to greatest: a +(-c) , b , c-(-b)

Quinzel and Joseph sell shoes. Last month Quinzel sold 18 less pairs

hichkok12 [17]

Answer:

Quinzel sold 17 pairs of shoes last month.

Step-by-step explanation:

Let be "Q" the number of pairs of shoes Quinzel sold last month and "J" the number of pairs of shoes Joseph sold last month.

Set up a system of equations:

$\left \{ {{Q=J-18} \atop {Q+J=52} \right.$

Solve for "J" from the first equation:

$J=Q+18$

Applying the Substitution Method, you get:

$Q+J=52\\\\Q+(Q+18)=52\\\\2Q=52-18\\\\Q=\frac{34}{2} \\\\Q=17$

Answer:

-1, 1

13, 15

Step-by-step explanation:

x and x+2 are the integers

x*(x+2)= 7(x+x+2) -1
x²+2x= 14x+14-1
x² - 12x -13= 0

Roots of the quadratic equation are: -1 and 13.

So the integers pairs are: -1, 1 and 13, 15

In Triangle ABC, AC is extended through C to D. If

DENIUS [597]

Answer:

X = 5 unit

Step-by-step explanation:

Given as , ABC is a Triangle ,

AC extended to through C to D

∠BAC = 6x + 10

∠ABC = 6x - 10

∠BCD = ∠ 8x + 20

When c extended to D then , ∠BCD is an external angle

∵ <u>External angle = Sum of opposite internal angles</u>

Or ,∠BCD = ∠BAC + ∠ABC

Or, ∠ 8x + 20 = 6x + 10 + 6x - 10

Or, ∠ 8x + 20 = 12x

Or, 12x - 8x = 20

∴ 4x = 20

So, x = $\frac{20}{4}$ = 5

Hence the value of X = 5 unit Answer
