Answer:

x = -2.3

Step-by-step explanation:

4x + 1.3 = -7.9

First we want to combine the like terms.

Subtract 1.3 from both sides.

4x = -9.2

Now we want to isolate x by dividing both sides by 4.

x = -2.3

Check your answer by plugging x back into the original equation.

4x + 1.3 = -7.9

4(-2.3) + 1.3 = -7.9

Multiply.

-9.2 + 1.3 = -7.9

Add.

-7.9 = -7/9

Your answer is correct.

Hope this helps!

Step-by-step explanation:

4x + 1.3 = - 7.9

4x = - 7.9 - 1.3

4x = - 9.2

x = - 9.2/4

= - 2.3

Answer:

  5/8 or 5/9

Step-by-step explanation:

The fraction will be exactly ...

  5/(8 1/2) = 10/17   ⇒   (8 1/2)×(10/17) = 5

__

The fraction will be approximately ...

  5/8 or 5/9

The denominator will be a number that makes (8 1/2)/(denominator) ≈ 1. For that denominator, the numerator will be 5, so that we have ...

  (8 1/2) × (5/denominator) ≈ 5

  (8 1/2)/(denominator) ≈ 1 .  . . . . . . . divide by 5

If we want the denominator to be an integer, we could choose either 8 or 9. If we choose 8, the result will be slightly more than 5; if we choose 9, the result will be slightly less.

  (8 1/2) × (5/8) = 5.3125 ≈ 5

  (8 1/2) × (5/9) = 4.722... ≈ 5

Either 5/8 or 5/9 will give a product of about 5.

Answer:

it should be the graph on the bottom right

Step-by-step explanation:

The income should be more than the cost in order to make a profit and that happens for Leanne when she sells 8 quilts, so the 8 should be on the x-axis (the axis named "Quilts Sold")

The income should be 0 in the beginning bc when she sells 0 quilts she will be earning 0.

after selling 8 quilts her income will be higher than her costs

(Though naming the y-axis as "profit" is not accurate bc when she sells 0 quilts she will lose money since she will be spend money to make the quilts but not earn the money to compensate for the cost).

with all of these reasons combined the correct should be the one on the bottom right

Step-by-step explanation:

1. m(angle A) is 90 degrees............[ tangent drawn from the centre of the circle is always perpendicular to the circle]

2.m(angle C) is also 90 degrees....[ tangent drawn from the centre of the circle is always perpendicular to the circle]

3. m(angle 1) is 57 degrees, angle A is 90 degrees, .....(given)

m(angle 4) + m(angle 1) + angle A = 180 ...............[ sum of measures of a triangle is always 180 degrees]

m(angle 4) = 180 - ( 57 + 90)

= 33 degrees

4. m(angle 3 ) is 63 degrees, m(angle C) is 90 degrees, .........[given]

m(angle 3) + m(angle 2) + angle C = 180 ...............[ sum of measures of a triangle is always 180 degrees]

m(angle 2) = 180 - ( 63 + 90)

= 27 degrees

Answer:

x= 7/20

Step-by-step explanation:

(5+2×8)/6=x(4+6)

(5+16) /6 = 4x+6x

21/6=10x (divide 21/6 by 3)

7/2=10x

7/2×1/10= x

x= 7/20

Answer:

  (a)  12.825 liters

Step-by-step explanation:

"Milli-" is the SI prefix for 1/1000. So, 475 milliliters is 475/1000 liters, or 0.475 liters.

27 of these will be a volume of ...

  (27)(0.475 L) = 12.825 L . . . . matches the first choice

Answer:

a) x= 29, y= 87

b) x= 19, y= 45

Step-by-step explanation:

Q5. a) Let the first number be x and the second number be y.

The sum of 2 integers is 116.

x +y= 116 -----(1)

The second number is three times the first number.

y= 3x -----(2)

Substitute (2) into (1):

x +3x= 116

4x= 116

x= 116 ÷4

x= 29

Substitute x= 29 into (2):

y= 3(29)

y= 87

b) Let the smaller number be x and the larger number be y.

x +y= 64 -----(1)

y -x= 26 -----(2)

Since we have to use substitution to solve the equations, let's first rewrite an equation to make one of the variables the subject of the equation.

From (1):

x= 64 -y -----(3)

Substitute (3) into (2):

y -(64 -y)= 26

y -64 +y= 26 (expand bracket)

2y= 26 +64 (simplify, +64 on both sides)

2y= 90

y= 90 ÷2

y= 45

Substitute y= 45 into (3):

x= 64 -45

x= 19

Answer:

x= 0.2323 1

10x =2.323 2

100x= 23.23 3

on subtracting 1 from 3

99x= 23

x = 23/99

similarly 0.22 will be 22/ 99

so by adding 23/99 and 22/ 99 we get required value

23/99 + 22/99 = 45/ 99

Answer:

Step-by-step explanation:

height after x seconds = -16x² - 2x + 600

-16x² - 2x + 600 = 450

16x² + 2x - 150 = 0

8x² + x - 75 = 0

Quadratic formula

x = [-1 ± √(1² – 4·8(-75))] / [2·8]

 = [-1 ± √2401] / 16

 = [-1 ± 49] /16

 = 3, -3⅛

-3⅛ is an extraneous solution, so x = 3 seconds.

Answer:

0.48 = 48% probability that an employee selected at random will need either corrective shoes or major dental work

Step-by-step explanation:

I am going to solve this question treating these events as Venn probabilities.

I am going to say that:

Event A: Employee needed corrective shoes.

Event B: Employee needed major dental work.

22% of the employees needed corrective shoes

This means that [tex]P(A) = 0.22[/tex]

29% needed major dental work

This means that [tex]P(B) = 0.29[/tex]

3% needed both corrective shoes and major dental work.

This means that [tex]P(A \cap B) = 0.03[/tex]

What is the probability that an employee selected at random will need either corrective shoes or major dental work?

This is:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

Replacing the values that we have:

[tex]P(A \cup B) = 0.22 + 0.29 - 0.03 = 0.48[/tex]

0.48 = 48% probability that an employee selected at random will need either corrective shoes or major dental work

Answer:

With algebraic expressions, you can’t add and subtract any terms like you can add and subtract numbers. Terms must be like terms in order to combine them. So, you can’t always simplify an algebraic expression by following the order of operations. You have to use the distributive property to rewrite the expression and then combine like terms to simplify. With numeric expressions, you can either simplify inside the parentheses first or use the distributive property first.

Step-by-step explanation:

Answer:

Algebraic expressions have terms, Terms must be like to add and subtract,    You can’t always follow the order of operations with algebraic expressions.
