Solve 7/b-36=a/72=28/b

1 answer:

6 0

(7/b)-36=(28/b)
(7/b)-(28/b)=36
7-28=36b
-21=36b
-21/36=b

Therefore:
28/b=a/72
28/(-21/36)=a/72
28 * (36/-21)=a/72
-48=a/72
72* -48 = a
a=-3456

a=-3456
b=-21/36

isosceles triangle has two sides of equal length the third is 7 less than twice the length of one of the other sideside the peri

Lostsunrise [7]

If your asking for the length of the third side, to find it first we have to build an equation.

let's take x as the length of the two sides with the same length.
so your equation should be,

x+x+2x-7=44cm
=4x-7=44cm
+7 +7
=4x=51cm
÷4 ÷4
=x=12.75cm

length of the sides with equal length= 12.75cm
length of the 3rd side= 12.75×2-7=18.5cm

check,
12.75cm+12.75cm+18.5cm=44cm
hope this helps.....

What is 1 + ( -2) ?

geniusboy [140]

When we have mixed signs we need to make it a negative. A plus and a minus or a minus and a plus are made into a minus by default.

With that in mind the question would not turn into 1 - 2 =

From here we take the sign of the bigger number. The bigger number would be negative 2 and we put it as the first part of our solution

This next step might be easier with a number line from -5 to 5

We start at positive 1 on the number line. From here we need to go left because when subtracting you go left. We move two spaces to the left. So the one goes to 0 and then it goes to -1

The answer would turn out to be negative one(-1)

1 - 2 = - 1

HOPE THIS HELPED!!! PLEASE DONT FORGET TO PUT THIS ANSWER AS THE BRAINLIEST. ALSO, LEAVE A HEART AND A 5 STAR TO LET PEOPLE KNOW IN THE FUTURE THAT THIS IS THE CORRECT ANSWER WITH A CORRECT EXPLANATION!! HAVE A GOOD DAY!

The diagram shows FGH, its medians, centroid P, and the lengths of some of the subsegments. Apply the Centroid Theorem to find o

nadezda [96]

Answer:

Step-by-step explanation:

We will use two properties to solve this problem,

1). Medians of a triangle bisect the sides of a triangle.

2). Centroid of a triangle divides the medians in the ratio of 2 : 1.

Length of FH = 2 × Length of HX

= 2 × 12

FH = 24

PF : PZ = 2 : 1

$\frac{PF}{PZ}=\frac{2}{1}$

$\frac{PF}{4}=\frac{2}{1}$

PF = 8

GX = GP + PX

GP = 9 [Given]

Since, $\frac{GP}{PX}=\frac{2}{1}$

PX = $\frac{9}{2}$ = 4.5

Therefore, GX = 9 + 4.5

GX = 13.5
