Find the value of x in the figure.

Answer:

x= -10

y= -43

Step-by-step explanation:

since both of your equations equals y just plug it into each other and than make the equation: 5x+7=4x-3

and than you can just start with the variables OR numbers and then simplify

5x+7=4x-3

5x+10=4x

10= -x

x= -10

so -10 for x

plug it in to one of your 2 equations to get y

5(-10)+7= y

-50+7=y

y= -43

Answer:

Triangle C

Step-by-step explanation:

Given

Triangle A, B, C and D

Required

Pick the odd triangle

From the attachment, we can see that:

A = Right angled triangle

B = Right angled triangle

C = Obtuse triangle

D = Right angled triangle

This is so because triangle C has one of its angles to be greater than 90 (i.e. 115) and other triangles (A, B and D) have an angle equal to 90, each.

Because C is obtuse and others are right-angled, then C is the odd triangle.

Answer:

its is because if you divide 6:6 by 6 it equals 1:1

Step-by-step explanation:

plz brainliest i need it to rank up

Answer:

They are equivalent

Step-by-step explanation:

1:1 is the same as 6:6 because 6:6 is technically 1:1 when you divide both sides by 6.

Answer:

126 dollars

Step-by-step explanation:

(i'm gonna be doing my work here, dont mind me LOL)

okay, so they sold 24 packs in 4 days. divide 24 by 4 and you get 6. multiply 6 by 3 and you get 18.

now, multiply 18 by seven and you get 126.

bam!! the dance team could earn 126$ in 7 days ^__^ hope you get an A!

Answer:

$126

Step-by-step explanation:

Let x = packs sold in 7 days

Set up a proportion.   days/days = packs/packs

4/7 = 24/x

4x = 24(7)  = 42 packs sold in 7 days

At $3/pack, the amount earned in 7 days =  3(42) = $126

Answer:

A

Step-by-step explanation:

Answer:

40 dollars

Step-by-step explanation:

25% of 16 minutes is 4 mins. 16+4=20 mins.

Answer:

Measuring an angle using a protractor in anticlockwise direction:  

This is measurement in anticlockwise direction. Thus, we will use the inner scale to measure the angle.

The centre of the protractor is placed on the vertex B of the angle ABC. The base line of the protractor should coincide...

Read the markings where the arm BC overlaps the markings on the protractor.

Step-by-step explanation:

Answer:

f(4) - g(3) = 28

Step-by-step explanation:

f(x) = 8x + 10

f(4) = 8(4) + 10

f(4) = 32 + 10

f(4) = 42

g(x) = 6x - 4

g(3) = 6(3) - 4

g(3) = 18 - 4

g(3) = 14

f(4) - g(3)

= 42 - 14

= 28

Answer:

$51.38

Step-by-step explanation:

1 - .25 = .75

you're paying 75% of the price

68.50 • .75 = 51.375 ≈ $51.38

Step-by-step explanation:

therefore x+6=0

x = -6 hope this helps and you understand it.

Answer:

[tex]Let~the~length~of~rectangle~be~'l'~and~its~width~be~'b'.\\According ~to ~question,\\l:b=11:3\\or, \frac{l}{b} =\frac{11}{3} \\or, l = \frac{11b}{3}\\Also,\\Perimeter~of~the~rectangle=308\\or, 2(l+b)=308\\or, l+b=154\\or, \frac{11 b}{3}+b =154 \\or, \frac{11b+3b}{3} =154\\or, 14b = 154(3)\\or, b=33 units\\So, ~the~width~of~rectangle~is~33units.[/tex]

Alternative method:

[tex]Let~the~length~and~width~of~the~rectangle~be~11x~and~3x.\\Given,\\Perimeter~of~the~rectangle = 308\\or, 2(11x+3x)=308\\or, 14x = 154\\or, x = 11\\Now,\\Width~of~the~rectangle,3x = 3(11)=33 units\\So,~the~width~of~the~rectangle~is~33units.[/tex]

Answer:

12

Step-by-step explanation:

substitute x = 7 into the equation:

[tex]4 (7-4)\\4(3)\\12[/tex]

Answer:

12

Step-by-step explanation:

First, you insert the 7 in place of the x. Then you do what is in the parenthesis, according to PEMDAS. 7-4 = 3. You end up with 4(3). You then do distributive property and you end up with 12.

Answer:

0.84 = 84% probability that the calculator has a good case and good batteries.

Step-by-step explanation:

We have these following percentages:

8% of a certain batch of calculators have a defective case.

11 % have defective batteries.

3% have both a defective case and defective batteries.

Using Venn Diagrams:

Event A: Defective Case

Event B: Defecitve Battery

So the probabilities are: [tex]P(A) = 0.08, P(B) = 0.11, P(A \cap B) = 0.03[/tex]

Probability of at least one problem:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B) = 0.08 + 0.11 - 0.03 = 0.16[/tex]

Find the probability that the calculator has a good case and good batteries.

No problems, so

[tex]p = 1 - P(A \cup B) = 1 - 0.16 = 0.84[/tex]

0.84 = 84% probability that the calculator has a good case and good batteries.

The probability that the calculator has a good case and good batteries is 0.84 or 84%

Since

8% of a certain batch of calculators have a defective case.

11 % have defective batteries.

3% have both a defective case and defective batteries.

So, the probability is

=  1- (0.08 + 0.11 - 0.03)

= 1 - 0.16

= 0.84

Therefore, The probability that the calculator has a good case and good batteries is 0.84 or 84%

Answer:

A=78ft

Step-by-step explanation:

The area of a trapezoid is A=(a+b)/2 *h

a=long base

b=short base

h=height

For your trapezoid, it will look like this:

a=15ft

b=11ft

h=6ft

Let's add those into the equation:

A=(15+11)/2 *6

Okay, let's solve it! Using PEMDAS, we know parenthesis are first.

A=26/2 *6

Now we divide!

A=13*6

Multiply! And don't forget to add your unit.

A=78ft
