Need help finding the value of x
Answer:
The value of x is 26.
Step-by-step explanation:
In a triangle, the total angles is 180°. In order to find the value of x, you have to add up all the angles in terms of x and make it equals to 180°
2x + 3x + 50 = 180
5x + 50 = 180
5x = 180 - 50
5x = 130
x = 130 ÷ 5
x = 26
As we know that,
Sum of all angles of triangle = 180°
Given,
Angles are 2x , 3x and 50°
Now,
[tex] \rightarrow \: 2x + 3x + 50 = 180[/tex]
When plus sign goes to another side then,it become minus.
[tex] \rightarrow \: 5x = 180 - 50[/tex]
[tex] \rightarrow \: 5x = 130[/tex]
[tex] \rightarrow \: x = \cancel \dfrac{130}{5} [/tex]
[tex] \rightarrow \: x = 26[/tex]
Hence,the value of x is 26°.

find the value of x in the triangle below
Answer:
x=109
Step-by-step explanation:
The angles inside of a triangle all add up to 180 degrees. So:
23+48+x=180
Simplify Like-Terms:
71+x=180
Subtract 71 from both sides:
x=109

LITTERLY HELP ME PLEASEE..... 2/x-4x/2x-3=-2
PLEASEE I INSERTED A PIC
Answer:
x = -3
Step-by-step explanation:
Given expression is,
[tex]\frac{2}{x}- \frac{4x}{2x-3}=-2[/tex]
[tex]\frac{2(2x-3)}{x(2x-3)}-\frac{4x(x)}{x(2x-3)}=-2[/tex]
[tex]\frac{2(2x-3)-4x^{2} }{x(2x-3)}=-2[/tex]
(4x - 6) - 4x² = -2x(2x - 3)
4x - 6 - 4x² = -4x² + 6x
4x - 6 = 6x
6x - 4x = -6
2x = -6
x = -3

Measure of Arc BC
Measure of Angle B
Measure of Angle C
Measure of Arc AB
Answer:
arc BC=96 degrees
angle B=55 degrees
angle C=77 degrees
arc AB=154 degrees
(check: 48+55+77=180 and 110+154+96=360)
Step-by-step explanation:
angles A, B, & C are inscribed angles
angle A=1/2 arc BC
arc BC=96
since arc AC=110, then arc AB=360-110-96
arc AB=154
angle B=1/2(110)
angle B=55
angle c=1/2(154)
angle c=77

The length of BC is four times the length of AB.
BC = 100 metres.
Work out the length AC.
It should be 125 as
BC=100
and it's four times the length of AB then
100/4=25
then 100+25=125

((x+7)^2-49)+((y+6)^2-36)=-60
get rid of parnthaeses
(x+7)^2-49+(y+6)^2-36=-60
(x+7)^2+(y+6)^2-85=-60

Cindy spent $65.25 on ingredients for blueberry pies and $62.84 on ingredients for cherry pies. Each slice of ple sells for $3.50.
Part A
Write an expression to represent Cindy's profit if she sells b slices of blueberry pie and C slices of cherry ple.
Part B
Cindy sells 24 slices of blueberry ple and 15 slices of cherry ple. The ne
xt day, she sold 26 slices of blueberry ple and 17 slices of cherry pie. What was her total profit?
The expression that represents Cindy's profit is $3.5b - $128.09.
Cindy's total profit is $30.82.
What is profit?Profit is total revenue less total cost. Total revenue is the selling price per unit multiplied by the total units sold.
Profit = total revenue - total cost
($3.50b) - ($65.25 + $62.84)
$3.5b - $128.09
What is Cindy's total profit?Profit for the first day = $3.5(24 + 15) - $128.09
= ($3.5 x 39) - $128.09
= $136.50 - $128.09
=$8.41
Profit for the next day = $3.5(26 + 17) - $128.09
= ($3.5 x 43) - $128.09
= $150.50 - $128.09
= $22.41
Total profit = $22.41 + $8.41 = $30.82

George, Charlotte and Louis share some money in the ratio 2:5:6 Louis gets £39 How much did they share?
Answer:
£84.5
Step-by-step explanation:
Given ratio = 2:5:6
Amount that Louis got from the total amount = £39
Step 1: Add the ratio together
2+5+6=13
Step 2: covert the given ratio into fraction
George ratio=2/13
Charlotte ratio=5/13
Louis ratio= 6/13
✓LET THE AMOUNT THAT WAS SHARED AMONG THEM= Y
But we know that Louis got £39, then we can compute How much did they shared using "Louiz" shrare as
Louis ratio= 6/13 × Y= £39
= 6Y/13 = 39
Cross multiply
13×39= 6Y
507= 6Y
Y= 84.5
Hence, the amount they shared was £84.5
